How to course correct when you simply can't stay the course

How to course correct when you simply can't stay the course De-risking during market volatility can be costly. Here’s how to do it without breaking the bank. The best course of action during market volatility is often inaction. That’s because selling riskier assets at a loss locks in those losses. It foregoes their potential for future growth, and it might also trigger capital gains taxes in the process. But if taking some sort of action feels necessary, then modestly reducing your overall risk exposure can be a reasonable alternative. Consider dialing down your existing stock allocation by a few percentage points, or lower the costs of recalibrating by using your future deposits instead. Either way, the solution may be the same: sprinkling in more bonds. Consider bonds to calm your investing nerves When people talk about diversification, equities like international stocks get most of the attention. But no less important in the role of managing risk are bonds. These are the loans given to governments and companies by investors, and while they're not completely risk-free (no asset is), the relatively-modest interest they tend to pay out can feel like a windfall when stock values are plunging. They won’t negate all of the volatility of stocks, but they can help smooth things out and preserve capital. This is why all of our recommended allocations include holding at least some bonds. You can easily dial the bond allocation up or down in our portfolios such as Core. And we also offer two portfolios comprised primarily of bonds, each one designed for a different use case: Target Income built with BlackRock, designed to help you limit market volatility, preserve wealth, and generate income. The Goldman Sachs Tax-Smart Bonds portfolio, designed for high-income individuals seeking a higher after-tax yield compared to a cash account. Don’t forget about the role of cash One of the best ways to mitigate your overall financial risk is by shoring up your emergency fund, which may include a high-yield cash account like our Cash Reserve. Imagine losing your income stream, and how much time you'd want to get back on your feet. A good place to start is 3-6 months' worth of your essential expenses, but your right amount is whatever helps you sleep more soundly at night. Cash Reserve offered by Betterment LLC and requires a Betterment Securities brokerage account. Betterment is not a bank. FDIC insurance provided by Program Banks, subject to certain conditions. Learn more. Steadying the ship during unsteady times As we mentioned up front, right-sizing your risk during downturns isn’t always cheap. But there are ways to minimize the costs. Lowering your risk profile incrementally is one of them, and stretching out your safety net is another. Either way, it’s okay to recalibrate your risk tolerance from time-to-time, and you can do it wisely with Betterment. -

Betterment’s portfolio construction methodology Learn more about the process that underpins all the portfolios we build on behalf of customers. Table of contents Introduction Global diversification and asset allocation Portfolio optimization Tax management using municipal bonds The Value Tilt portfolio strategy The Innovative Technology portfolio strategy The Socially Responsible Investing portfolio strategies Conclusion Citations I. Introduction Betterment builds investment portfolios designed to help you make the most of your money and live the life you want. This guide lays out our portfolio construction process, one informed by real-world evidence and systematic decision-making. The Betterment Core portfolio serves as the foundation for all of the globally-diversified portfolios we construct. From there, specific adjustments are applied to other portfolios based on the investment objective of their particular strategies. These adjustments include additional allocations to value-focused or innovative stocks, or adherence to Socially Responsible Investing (SRI) criteria. For more information on the third-party portfolios we offer, such as the Goldman Sachs Smart Beta portfolio, see their respective pages and disclosures. When building a portfolio, any investment manager faces two main tasks: asset class selection and portfolio optimization. We detail our approach to these in the sections that follow. Our fund selection process, while equally as important, is covered in a separate methodology. II. Global diversification and asset allocation An optimal asset allocation is one that lies on the efficient frontier, which is a set of portfolios that seek to achieve the maximum objective for any given feasible level of risk. The objective of most long-term portfolio strategies is to maximize return for a given level of risk, which is measured in terms of volatility—the dispersion of those returns. In line with our approach of making systematic decisions backed by research, Betterment’s asset allocation for the invested (non-cash) portion of portfolios is based on a theory by economist Harry Markowitz called Modern Portfolio Theory.1 A major tenet of Modern Portfolio Theory is that any asset included in a portfolio should not be assessed by itself, but rather, its potential risk and return should be analyzed as a contribution to the whole portfolio. Modern Portfolio Theory seeks to maximize expected return given an expected risk level or, equivalently, minimize expected risk given an expected return. Other forms of portfolio construction may legitimately pursue other objectives, such as optimizing for income, or minimizing loss of principal. Asset class selection Our approach to asset allocation starts with a universe of investable assets, which could be thought of as the “global market” portfolio.2 To capture the exposures of the asset classes for the global market portfolio, we evaluate available exchange-traded funds (ETFs) that represent each class in the theoretical market portfolio. We base our asset class selection on ETFs because this aligns portfolio construction with our fund selection methodology. All of our portfolios are constructed of the following asset classes: Stocks U.S. stocks International developed market stocks Emerging market stocks Bonds U.S. short-term treasury bonds U.S. inflation-protected bonds U.S. investment-grade bonds U.S. municipal bonds International developed market bonds Emerging market bonds We select U.S. and international developed market stocks as a core part of the portfolio. Historically, stocks exhibit a high degree of volatility, but provide some degree of inflation protection. Even though significant historical drawdowns, such as the global financial crisis in 2008 and pandemic outbreak in 2020, demonstrate the possible risk of investing in stocks, longer-term historical data and our forward expected returns calculations suggest that developed market stocks remain a core part of any asset allocation aimed at achieving positive returns. This is because, over the long term, developed market stocks have tended to outperform bonds on a risk-adjusted basis. To achieve a global market portfolio, we also include stocks from less developed economies, called emerging markets. Generally, emerging market stocks tend to be more volatile than U.S. and international developed stocks. And while our research shows high correlation between this asset class and developed market stocks, their inclusion on a risk-adjusted basis is important for global diversification. Note that we exclude frontier markets, which are even smaller than emerging markets, due to their widely-varying definition, extreme volatility, small contribution to global market capitalization, and cost to access. We incorporate bond exposure because, historically, bonds have a low correlation with stocks, and they remain an important way to dial down the overall risk of a portfolio. To promote diversification and leverage various risk and reward tradeoffs, we include exposure to several asset classes of bonds. All Betterment-constructed portfolios with the exception of the Flexible portfolio target a small operational cash allocation in taxable accounts, health savings accounts, and individual retirement accounts (IRAs). Asset classes excluded from Betterment portfolios While Modern Portfolio Theory would have us craft a portfolio to represent the total market, including all available asset classes, we exclude some asset classes whose cost and/or lack of data outweighs the potential benefit gained from their inclusion. Our portfolio construction process excludes commodities and natural resources asset classes. Specifically, while commodities represent an investable asset class in the global financial market, we have excluded commodities ETFs because of their low contribution to a global stock/bond portfolio's risk-adjusted return. In addition, real estate investment trusts (REITs), which tend to be well marketed as a separate asset class, are not explicitly included in our portfolios. We do provide exposure to real estate, but as a sector within stocks. Adding additional real estate exposure by including a REIT asset class would overweight the exposure to real estate relative to the overall market. Incorporating awareness of a benchmark Before 2024, we managed our portfolios in a “benchmark agnostic” manner, meaning we did not incorporate consideration of global stock and bond indices in our portfolio optimization, though we have always sought to optimize the expected risk-adjusted return of the portfolios we construct for clients. The “risk” element of this statement represents volatility and the related drawdown potential of the portfolio, but it could also represent the risk in the deviation of the portfolio’s performance relative to a benchmark. In an evolution of our investment process, in 2024 we updated our portfolio methodology to become “benchmark aware,” as we now calibrate our exposures based on a custom benchmark that expresses our preference for diversifying across global stocks and bonds. A benchmark, which comes in the form of a broad-based market index or a combination of indices, serves as a reference point when approaching asset allocation, understanding investment performance, and aligning the expectations of portfolio managers and clients. In our case, we created a custom benchmark that most closely aligns with our future expectations for global markets. The custom benchmark we have selected is composed of: The MSCI All Country World stock IMI index (MSCI ACWI IMI) The Bloomberg U.S. Universal Bond index The S&P US Treasury Bond 0-1 Year Index (for <40% stock allocations) Our custom benchmark is composed of 101 risk levels of varying percentage weightings of the stock and bond indexes, which correspond to the 101 risk level allocations in our Core portfolio. At low risk levels (allocations that are less than 40% stocks), we layer an allocation to the S&P US Treasury Bond 0-1 Year Index, which represents short-term bonds, into the blended benchmark. We believe that incorporating this custom benchmark into our process reinforces the discipline of carefully evaluating the ways in which our portfolios’ performance could veer from global market indices and deviate from our clients’ expectations. We have customized the benchmark with 101 risk levels so that it serves clients’ varying investment goals and risk tolerances. As we will explore in the following section, establishing a benchmark allows us to apply constraints to our portfolio optimization that ensures the portfolio’s asset allocation does not vary significantly from the geographic and market-capitalization size exposures of a sound benchmark. Our benchmark selection also makes explicit that the portfolio delivers global diversification rather than the more narrowly-concentrated and home-biased exposures of other possible benchmarks such as the S&P 500. III. Portfolio optimization As an asset manager, we fine-tune the investments our clients hold with us, seeking to maximize return potential for the appropriate amount of risk each client can tolerate. We base this effort on a foundation of established techniques in the industry and our own rigorous research and analysis. While most asset managers offer a limited set of model portfolios at a defined risk scale, our portfolios are designed to give customers more granularity and control over how much risk they want to take on. Instead of offering a conventional set of three portfolio choices—aggressive, moderate, and conservative—our portfolio optimization methods enable our Core portfolio strategy to be customized to 101 different stock-bond risk levels. Optimizing portfolios Modern Portfolio Theory requires estimating variables such as expected-returns, covariances, and volatilities to optimize for portfolios that sit along an efficient frontier. We refer to these variables as capital market assumptions (CMAs), and they provide quantitative inputs for our process to derive favorable asset class weights for the portfolio strategy. While we could use historical averages to estimate future returns, this is inherently unreliable because historical returns do not necessarily represent future expectations. A better way is to utilize the Capital Asset Pricing Model (CAPM) along with a utility function which allows us to optimize for the portfolio with a higher return for the risk that the investor is willing to accept. Computing forward-looking return inputs Under CAPM assumptions, the global market portfolio is the optimal portfolio. Since we know the weights of the global market portfolio and can reasonably estimate the covariance of those assets, we can recover the returns implied by the market.3 This relationship gives rise to the equation for reverse optimization: μ = λ Σ ωmarket Where μ is the return vector, λ is the risk aversion parameter, Σ is the covariance matrix, and ωmarket is the weights of the assets in the global market portfolio.5 By using CAPM, the expected return is essentially determined to be proportional to the asset’s contribution to the overall portfolio risk. It’s called a reverse optimization because the weights are taken as a given and this implies the returns that investors are expecting. While CAPM is an elegant theory, it does rely on a number of limiting assumptions: e.g., a one period model, a frictionless and efficient market, and the assumption that all investors are rational mean-variance optimizers.4 In order to complete the equation above and compute the expected returns using reverse optimization, we need the covariance matrix as an input. This matrix mathematically describes the relationships of every asset with each other as well as the volatility risk of the assets themselves. In another more recent evolution of our investment process, we also attempt to increase the robustness of our CMAs by averaging in the estimates of expected returns and volatilities published by large asset managers such as BlackRock, Vanguard, and State Street Global Advisors. We weight the contribution of their figures to our final estimates based on our judgment of the external provider’s methodology. Constrained optimization for stock-heavy portfolios After formulating our CMAs for each of the asset classes we favor for inclusion in our portfolio methodology, we then solve for target portfolio allocation weights (the specific set of asset classes and the relative distribution among those asset classes in which a portfolio will be invested) with the range of possible solutions constrained by limiting the deviation from the composition of the custom benchmark. To robustly estimate the weights that best balance risk and return, we first generate several thousand random samples of 15 years of expected returns for the selected asset classes based on our latest CMAs, assuming a multivariate normal distribution. For each sample of 15 years of simulated expected return data, we find a set of allocation weights subject to constraints that provide the best risk-return trade-off, expressed as the portfolio’s Sharpe ratio, i.e., the ratio of its return to its volatility. Averaging the allocation weights across the thousands of return samples gives a single set of allocation weights optimized to perform in the face of a wide range of market scenarios (a “target allocation”). The constraints are imposed to make the portfolio weights more benchmark-aware by setting maximum and minimum limits to some asset class weights. These constraints reflect our judgment of how far the composition of geographic regions within the portfolio’s stock and bond allocations should differ from the breakdown of the indices used in the benchmark before the risk of significantly varied performance between the portfolio strategy and the benchmark becomes untenable. For example, the share of the portfolio’s stock allocation assigned to international developed stocks should not be profoundly different from the share of international developed stocks within the MSCI ACWI IMI. We implement caps on the weights of emerging market stocks and bonds, which are often projected to have high returns in our CMAs, and set minimum thresholds for U.S. stocks and bonds. This approach not only ensures our portfolio aligns more closely with the benchmark, but it also mitigates the risk of disproportionately allocating to certain high expected return asset classes. Constrained optimization for bond-heavy portfolios For Betterment portfolios that have more than or equal to a 60% allocation of bonds, the optimization approach differs in that expected returns are maximized for target volatilities assigned to each risk level. These volatility targets are determined by considering the volatility of the equivalent benchmark. Manually established constraints are designed to manage risk relative to the benchmark, instituting a declining trend in emerging market stock and bond exposures as stock allocations (i.e., the risk level) decreases. Meaning that investors with more conservative risk tolerances have reduced exposures to emerging market stocks and bonds because emerging markets tend to have more volatility and downside-risk relative to more established markets. Additionally, as the stock allocation percentage decreases, we taper the share of international and U.S. aggregate bonds within the overall bond allocation, and increase the share of short-term Treasury, short-term investment grade, and inflation-protected bonds. This reflects our view that investors with more conservative risk tolerances should have increased exposure to short-term Treasury, short-term investment grade, and inflation-protected bonds relative to riskier areas of fixed income. The lower available risk levels of our portfolios demonstrate capital preservation objectives, as the shorter-term fixed income exposures likely possess less credit and duration risk. Clients invested in the Core portfolio at conservative allocation levels will likely therefore not experience as significant drawdowns in the event of waves of defaults or upward swings in interest rates. Inflation-protected securities also help buffer the lower risk levels from upward drafts in inflation. IV. Tax management using municipal bonds For investors with taxable accounts, portfolio returns may be further improved on an after-tax basis by utilizing municipal bonds. This is because the interest from municipal bonds is exempt from federal income tax. To take advantage of this, we incorporate municipal bonds within the bond allocations of taxable accounts. Other types of bonds remain for diversification reasons, but the overall bond tax profile is improved by incorporating municipal bonds. For investors in states with some of the highest tax rates—New York and California—Betterment can optionally replace the municipal bond allocation with a more narrow set of bonds for that specific state, further saving the investor on state taxes. Betterment customers who live in NY or CA can contact customer support to take advantage of state-specific municipal bonds. V. The Value Tilt portfolio strategy Existing Betterment customers may recall that historically the Core portfolio held a tilt to value companies, or businesses that appear to be potentially undervalued based on metrics such as price-to-earnings (P/E) ratios. Recent updates, however, have deprecated this explicit tilt that was expressed via large-, mid-, and small-capitalization U.S. value stock ETFs, while maintaining some exposure to value companies through broad market U.S. stock funds. We no longer favor allocating to value stock ETFs within our portfolio methodology in large part as a result of our adoption of a broad market benchmark, which highlights the idiosyncratic nature of such tilts, sometimes referred to as “off benchmark bets.” We believe our chosen benchmark that represents stocks through the MSCI ACWI IMI, which holds a more neutral weighting to value stocks, more closely aligns with the risk and return expectations of Betterment’s diverse range of client types across individuals, financial advisors, and 401(k) plan sponsors. Additionally, as markets have grown more efficient and value factor investing more popularized, potentially compressing the value premium, we have a marginally less favorable view of the forward-looking, risk-adjusted return profile of the exposure. That being said, we have not entirely lost conviction in the research supporting the prudence of value investing. The value factor’s deep academic roots drove decisions to incorporate the value tilt into Betterment’s portfolios from our company’s earliest days. For investors who wish to remain invested in a value strategy, we have added the Value Tilt portfolio, a separate option from the Core portfolio, to our investing offering. The Value Tilt portfolio maintains the Core portfolio’s global diversification across stocks and bonds while including a sleeve within the stock allocation of large-, mid-, and small-capitalization U.S. value funds. We calibrated the size of the value fund exposure based on a certain target historical tracking error to the backtested performance of the latest version of the Core portfolio. Based on this approach, investors should expect the Value Tilt portfolio to generally perform similarly to Core, with the potential to under- or outperform based on the return of U.S. value stocks. With the option to select between the Value Tilt portfolio or a Core portfolio now without an explicit allocation to value, the investment flexibility of the Betterment platform has improved. VI. The Innovative Technology portfolio strategy In 2021, Betterment launched the Innovative Technology portfolio to provide access to the thematic trend of technological innovation. The portfolio’s investment premise is based upon the thesis that, over the long term, the companies innovating and disrupting their respective industries are shaping our global economy and may be the winners of the next industrial revolution. Some of these themes the portfolio seeks to provide increased exposure to are: Artificial intelligence Alternative finance Clean energy Manufacturing Biotechnology Similar to the Value Tilt portfolio, the Core portfolio is used as the foundation of construction for the Innovative Technology portfolio. With this portfolio strategy, we calibrated the size of the innovative technology funds’ exposure based on a certain target historical tracking error to the backtested performance of the latest version of the Core portfolio. Through this process, the Innovative Technology portfolio maintains the same globally-diversified, low-cost approach that is found in Betterment’s investment philosophy. The portfolio, however, has increased exposure to risk given that innovation requires a long-term view, and may face uncertainties along the way. It may outperform or underperform depending on the return experience of the innovative technology funds’ exposure and the thematic landscape. To learn more, read the Innovative Technology portfolio disclosure. VII. The Socially Responsible Investing portfolio strategies Betterment introduced its first Socially Responsible Investing (SRI) portfolio in 2017 and has since expanded the options to include three distinct portfolios: Broad Impact, Social Impact, and Climate Impact. These SRI portfolios are built on the same foundational principles as the Core portfolio, utilizing various asset classes to create globally-diversified portfolios. However, they incorporate socially-responsible ETFs that align with specific Environmental, Social, and Governance (ESG) and shareholder engagement mandates, tailored to each SRI focus. Betterment’s SRI approach emphasizes three core dimensions: Reducing exposure to companies engaged in unsustainable activities Increasing investments in those addressing environmental and social challenges Allocating to funds that utilize shareholder engagement to promote responsible corporate behavior. This methodology ensures diversified, cost-efficient portfolios that resonate with investors' values. For more information, read our full Socially Responsible Investing portfolios methodology. VIII. Conclusion After setting the strategic weight of assets in our various Betterment portfolios, the next step in implementing the portfolio construction process is our fund selection methodology, which selects the appropriate ETFs for the respective asset exposure in a generally low-cost, tax-efficient way. In keeping with our philosophy, that process, like our portfolio construction process, is executed in a systematic, rules-based way, taking into account the cost of the fund and the liquidity of the fund. Beyond ticker selection is our established process for allocation management—how we advise downgrading risk over time. The level of granularity in allocation management provides the flexibility to align to multiple goals with different timelines and circumstances. Most of our portfolios contain 101 individualized risk levels (each with a different percentage of the portfolio invested in stocks vs. bonds, informed by your financial goals, time horizon and risk tolerance). Finally, our overlay features of automated rebalancing, tax-loss harvesting, and our methodology for automatic asset location, which we call Tax Coordination, are designed to be used to help further maximize individualized, after-tax returns. Together these processes put our principles into action, to help each and every Betterment customer maximize value while invested at Betterment and when they take their money home. IX.

Take on More Control with Flexible Portfolios For experienced investors looking to tweak asset class weights, we offer a Flexible portfolio option. Let’s say you’re an experienced investor. You’re already a Betterment customer—or you’re considering becoming one. You dig our personalized approach to automated investing, but you’d like to get granular with your portfolio’s specific asset class weights. Well, our Flexible portfolio option lets you do just that. It starts with our Core portfolio’s distribution of asset classes before handing over the wheel to you, so to speak. In the process, you get access to additional asset classes including Commodities, High Yield Bonds, and REITs. If all of this sounds a little overwhelming or confusing, you should probably consider sticking with one of our expert-built, curated portfolio options. But for those comfortable with the added risk, research, and responsibility in general that comes with managing your own portfolio, a Flexible portfolio may be a good fit. Keep reading for more details on the pros, cons and other considerations of this option. The benefits of a Flexible portfolio You get a sound start with the Betterment portfolio strategy Our investing advice has several layers, and the portfolio we recommend to you is just one of them. At the core is our approach to building a diversified, risk-efficient portfolio strategy and our cost-aware selection of ETFs. A Flexible portfolio lets you benefit from this approach and start with the asset class weighting we believe comprises a diversified portfolio, but gives you the final say in those weights. You get principled feedback on your Flexible portfolio You can tweak the asset class weights, but we’ll still rate the diversification and relative risk of those tweaks before any investment changes are actually made. We want any customer with a Flexible portfolio to better understand the risks of the changes they’re considering. This also lets you experiment with different weights in theory before putting them into practice. You can still benefit from our automation and tax optimization Although the use of a Flexible portfolio means your preferences may deviate from our portfolio recommendation, you still get access to our automated investing and tax features. These include things like automatic rebalancing and Tax Loss Harvesting. Altering or removing asset classes altogether, however, may impact the effectiveness of tax-saving strategies. The drawbacks of a Flexible portfolio Adjusting an investment portfolio requires careful consideration, experience, and a higher level of effort beyond choosing one of our preset portfolio strategies. Your performance may be better or worse than the performance of those portfolio strategies with a comparable level of risk. And beyond the potential for diminished tax-saving strategies, choosing a Flexible portfolio also disables the Auto-adjust feature. This feature automatically “glides” your portfolio to a lower overall risk level as you get closer to the end date of your goal. Without it, you’ll be responsible for manually maintaining the appropriate allocation of stocks and/or bonds and its corresponding risk level.

Betterment's Socially Responsible Investing portfolios methodology
Betterment's Socially Responsible Investing portfolios methodology Jun 18, 2026 12:00:00 AM Learn how we construct our Socially Responsible Investing (SRI) portfolios. Table of Contents Introduction How do we define SRI? The Challenges of SRI Portfolio Construction How is Betterment’s Broad Impact portfolio constructed? How is Betterment’s Climate Impact portfolio constructed? How is Betterment’s Social Impact portfolio constructed? Conclusion Introduction Betterment launched its first Socially Responsible Investing (SRI) portfolio in 2017, and has widened the investment options under that umbrella since then. Within Betterment’s SRI options, we currently offer a Broad Impact portfolio and two additional, more focused SRI portfolio options: a Social Impact SRI portfolio (focused on social empowerment) and a Climate Impact SRI portfolio (focused on climate-conscious investments). These portfolios represent a diversified, relatively low-cost solution constructed using exchange traded funds (ETFs), which will be continually improved upon as costs decline, more data emerges, and as a result, the availability of SRI funds broadens. How do we define SRI? Our approach to SRI has three fundamental dimensions that shape our portfolio construction mandates: Reducing exposure to investments involved in unsustainable activities and environmental, social, or governmental controversies. Increasing exposure to investments that work to address solutions for core environmental and social challenges in measurable ways. Allocating to investments that use shareholder engagement tools, such as shareholder proposals and proxy voting, to incentivize socially responsible corporate behavior. SRI is the traditional name for the broad concept of values-driven investing (many experts now favor “sustainable investing” as the name for the entire category). Our SRI approach uses SRI mandates based on a set of industry criteria known as “ESG,” which stands for Environmental, Social and Governance. ESG refers specifically to the quantifiable dimensions of a company’s standing along each of its three components. Betterment’s approach expands upon the ESG-investing framework with exposure to investments that use complementary shareholder engagement tools. Betterment does not directly select companies to include in, or exclude from, the SRI portfolios. Rather, Betterment identifies ETFs that have been classified as ESG or similar by third-parties and considers internally developed “SRI mandates” alongside other qualitative and quantitative factors to select ETFs to include in its SRI portfolios. Betterment's SRI portfolios also target a small operational cash allocation in taxable accounts, health savings accounts, and individual retirement accounts (IRAs). Using SRI Mandates One aspect of improving a portfolio’s ESG exposure is reducing exposure to companies that engage in certain activities that may be considered undesirable because they do not align with specific values. These activities may include selling tobacco, military weapons, civilian firearms, as well as involvement in recent and ongoing ESG controversies. However, SRI is about more than just adjusting your portfolio to minimize companies with a poor social impact. For each Betterment SRI portfolio, the portfolio construction process considers one or more internally developed “SRI mandates.” Betterment’s SRI mandates are sustainable investing objectives that we include in our portfolios’ exposures. SRI Mandate Description Betterment SRI Portfolio Mapping ESG Mandate ETFs tracking indices which are constructed with reference to some form of ESG optimization, which promotes exposure to Environmental, Social, and Governance pillars. Broad, Climate, Social Impact Portfolios Fossil Fuel Divestment Mandate ETFs tracking indices which are constructed with the aim of excluding stocks in companies with major fossil fuels holdings (divestment). Climate Impact Portfolio Carbon Footprint Mandate ETFs tracking indices which are constructed with the aim of minimizing exposure to carbon emissions across the entire economy (rather than focus on screening out exposure to stocks primarily in the energy sector). Climate Impact Portfolio Green Financing Mandates ETFs tracking indices focused on financing environmentally beneficial activities directly. Climate Impact Portfolio Gender Equity Mandate ETFs tracking indices which are constructed with the aim of representing the performance of companies that seek to advance gender equality. Social Impact Portfolio Social Equity Mandate ETFs managed with the aim of obtaining exposures in investments that seek to advance vulnerable, disadvantaged, or underserved social groups. The Gender Equity Mandate also contributes to fulfilling this broader mandate. Social Impact Portfolio Shareholder Engagement Mandate In addition to the mandates listed above, Betterment’s SRI portfolios are constructed using a shareholder engagement mandate. One of the most direct ways a shareholder can influence a company’s decision making is through shareholder proposals and proxy voting. Publicly traded companies have annual meetings where they report on the business’s activities to shareholders. As a part of these meetings, shareholders can vote on a number of topics such as share ownership, the composition of the board of directors, and executive level compensation. Shareholders receive information on the topics to be voted on prior to the meeting in the form of a proxy statement, and can vote on these topics through a proxy card. A shareholder can also make an explicit recommendation for the company to take a specific course of action through a shareholder proposal. ETF shareholders themselves do not vote in the proxy voting process of underlying companies, but rather the ETF fund issuer participates in the proxy voting process on behalf of their shareholders. As investors signal increasing interest in ESG engagement, more ETF fund issuers have emerged that play a more active role engaging with underlying companies through proxy voting to advocate for more socially responsible corporate practices. These issuers use engagement-based strategies, such as shareholder proposals and director nominees, to engage with companies to bring about ESG change and allow investors in the ETF to express a socially responsible preference. For this reason, Betterment includes a Shareholder Engagement Mandate in its SRI portfolios. Mandate Description Betterment SRI Portfolio Mapping Shareholder Engagement Mandate ETFs which aim to fulfill one or more of the above mandates, not via allocation decisions, but rather through the shareholder engagement process, such as proxy voting. Broad, Climate, Social Impact Portfolios The Challenges of SRI Portfolio Construction For Betterment, three limitations have a large influence on our overall approach to building an SRI portfolio: 1. Many existing SRI offerings in the market have serious shortcomings. Many SRI offerings today sacrifice sufficient diversification appropriate for investors who seek market returns, and/or do not provide investors an avenue to use collective action to bring about ESG change. Betterment’s SRI portfolios do not sacrifice global diversification. Consistent with our core principle of global diversification and to ensure both domestic and international bond exposure, we’re still allocating to some funds without an ESG mandate, until satisfactory solutions are available within those asset classes. Additionally, all three of Betterment’s SRI portfolios include a partial allocation to an engagement-based socially responsible ETF using shareholder advocacy as a means to bring about ESG-change in corporate behavior. Engagement-based socially responsible ETFs have expressive value in that they allow investors to signal their interest in ESG issues to companies and the market more broadly, even if particular shareholder campaigns are unsuccessful. 2. Integrating values into an ETF portfolio may not always meet every investor’s expectations. For investors who prioritize an absolute exclusion of specific types of companies above all else, certain approaches to ESG will inevitably fall short of expectations. For example, many of the largest ESG funds focused on US Large Cap stocks include some energy companies that engage in oil and natural gas exploration, like Hess. While Hess might not meet the criteria of the “E” pillar of ESG, it could still meet the criteria in terms of the “S” and the “G.” Understanding that investors may prefer to focus specifically on a certain pillar of ESG, Betterment has made three SRI portfolios available. The Broad Impact portfolio seeks to balance each of the three dimensions of ESG without diluting different dimensions of social responsibility. With our Social Impact portfolio, we sharpen the focus on social equity with partial allocations to gender diversity and veteran impact focused funds. With our Climate Impact portfolio, we sharpen the focus on controlling carbon emissions and fostering green solutions. 3. Most available SRI-oriented ETFs present liquidity limitations. While SRI-oriented ETFs have relatively low expense ratios compared to SRI mutual funds, our analysis revealed insufficient liquidity in many ETFs currently on the market. Without sufficient liquidity, every execution becomes more expensive, creating a drag on returns. Median daily dollar volume is one way of estimating liquidity. Higher volume on a given asset means that you can quickly buy (or sell) more of that asset in the market without driving the price up (or down). The degree to which you can drive the price up or down with your buying or selling must be treated as a cost that can drag down on your returns. To that end, Betterment reassesses the funds available for inclusion in these portfolios regularly. In balancing cost and value for the portfolios, the options are limited to funds of certain asset classes such as US stocks, Developed Market stocks, Emerging Market stocks, US Investment Grade Corporate Bonds, US High Quality bonds, and US Mortgage-Backed Securities. How is Betterment’s Broad Impact portfolio constructed? Betterment’s Broad Impact portfolio invests assets in socially responsible ETFs to obtain exposure to both the ESG and Shareholder Engagement mandates, as highlighted in the table above. It focuses on ETFs that consider all three ESG pillars, and includes an allocation to an engagement-based SRI ETF. Broad ESG investing solutions are currently the most liquid, highlighting their popularity amongst investors. In order to maintain geographic and asset class diversification and to meet our requirements for lower cost and higher liquidity in all SRI portfolios, we continue to allocate to some funds that do not reflect SRI mandates, particularly in bond asset classes. How is Betterment’s Climate Impact portfolio constructed? Betterment offers a Climate Impact portfolio for investors that want to invest in an SRI strategy more focused on the environmental pillar of “ESG” rather than focusing on all ESG dimensions equally. Betterment’s Climate Impact portfolio invests assets in socially responsible ETFs and is constructed using the following mandates that seek to achieve divestment and engagement: ESG, carbon footprint reduction, fossil fuel divestment, shareholder engagement, and green financing. The Climate Impact portfolio was designed to give investors exposure to climate-conscious investments, without sacrificing proper diversification and balanced cost. Fund selection for this portfolio follows the same guidelines established for the Broad Impact portfolio, as we seek to incorporate broad based climate-focused ETFs with sufficient liquidity relative to their size in the portfolio. How can the Climate Impact portfolio help to positively affect climate change? The Climate Impact portfolio is allocated to iShares MSCI ACWI Low Carbon Target ETF (CRBN), an ETF which seeks to track the global stock market, but with a bias towards companies with a lower carbon footprint. By investing in CRBN, investors are actively supporting companies with a lower carbon footprint, because CRBN overweights these stocks relative to their high-carbon emitting peers. One way we can measure the carbon impact a fund has is by looking at its weighted average carbon intensity, which measures the weighted average of tons of CO2 emissions per million dollars in sales, based on the fund's underlying holdings. Based on weighted average carbon intensity data from MSCI, Betterment’s 100% stock Climate Impact portfolio has carbon emissions per unit sales that are more than 47% lower than Betterment’s 100% stock Core portfolio as of March 12, 2025*. *Target investments, actual holdings will vary. Additionally, a portion of the Climate Impact portfolio is allocated to fossil fuel reserve funds. Rather than ranking and weighting funds based on a certain climate metric like CRBN, fossil fuel reserve free funds instead exclude companies that own fossil fuel reserves, defined as crude oil, natural gas, and thermal coal. By investing in fossil fuel reserve free funds, investors are actively divesting from companies with some of the most negative impact on climate change, including oil producers, refineries, and coal miners such as Chevron, ExxonMobile, BP, and Peabody Energy. Another way that the Climate Impact portfolio promotes a positive environmental impact is by investing in bonds that fund green projects. The Climate Impact portfolio invests in iShares Global Green Bond ETF (BGRN), which tracks the global market of investment-grade bonds linked to environmentally beneficial projects, as determined by MSCI. These bonds are called “green bonds.” The green bonds held by BGRN fund projects in a number of environmental categories defined by MSCI including alternative energy, energy efficiency, pollution prevention and control, sustainable water, green building, and climate adaptation. How is Betterment’s Social Impact portfolio constructed? Betterment offers a Social Impact portfolio for investors that want to invest in a strategy more focused on the social pillar of ESG investing (the S in ESG). Betterment’s Social Impact portfolio invests assets in socially responsible ETFs and is constructed using the following mandates: ESG, gender equity, social equity, and shareholder engagement. The Social Impact portfolio was designed to give investors exposure to investments which promote social empowerment without sacrificing proper diversification and balanced cost. Fund selection for this portfolio follows the same guidelines established for the Broad Impact portfolio discussed above, as we seek to incorporate broad based ETFs that focus on social empowerment with sufficient liquidity relative to their size in the portfolio. How does the Social Impact portfolio help promote social empowerment? The Social Impact portfolio shares many of the same holdings as Betterment’s Broad Impact portfolio. The Social Impact portfolio additionally looks to further promote the “social” pillar of ESG investing by allocating to the following ETFs: SPDR SSGA Gender Diversity Index ETF (SHE) Academy Veteran Impact ETF(VETZ) Goldman Sachs JUST U.S. Large Cap Equity ETF (JUST) SHE is a US Stock ETF that allows investors to invest in more female-led companies compared to the broader market. In order to achieve this objective, companies are ranked within each sector according to their ratio of women in senior leadership positions. Only companies that rank highly within each sector are eligible for inclusion in the fund. By investing in SHE, investors are allocating more of their money to companies that have demonstrated greater gender diversity within senior leadership than other firms in their sector. VETZ, the Academy Veteran Impact ETF, is a US Bond ETF and is the first publicly traded ETF to primarily invest in loans to U.S. service members, military veterans, their survivors, and veteran-owned businesses. A majority of the underlying assets consist of loans to veterans or their families. The fund primarily invests in Mortgage-Backed Securities that are guaranteed by government-sponsored enterprises, such as Ginnie Mae, Fannie Mae, and Freddie Mac. The fund also invests in pools of small business loans backed by the Small Business Administration (SBA). JUST, Goldman Sachs JUST U.S. Large Cap Equity ETF, invests in U.S. companies promoting positive change on key social issues, such as worker wellbeing, customer privacy, environmental impact, and community strength, based on the values of the American public as identified by JUST Capital’s polling. Investment in socially responsible ETFs varies by portfolio allocation; not all allocations include the specific ETFs listed above. For more information about these social impact ETFs, including any associated risks, please see our disclosures. Should we expect any difference in an SRI portfolio’s performance? One might expect that a socially responsible portfolio could lead to lower returns in the long term compared to another, similar portfolio. The notion behind this reasoning is that somehow there is a premium to be paid for investing based on your social ideals and values. A white paper written in partnership between Rockefeller Asset Management and NYU Stern Center for Sustainable Business studied 1,000+ research papers published from 2015 to 2020 analyzing the relationship between ESG investing and performance. The primary takeaway from this research was that they found “positive correlations between ESG performance and operational efficiencies, stock performance, and lower cost of capital.” When ESG factors were considered in the study, there seemed to be improved performance potential over longer time periods and potential to also provide downside protection during periods of crisis. It’s important to note that performance in the SRI portfolios can be impacted by several variables, and is not guaranteed to align with the results of this study. Dividend Yields Could Be Lower Using the SRI Broad Impact portfolio for reference, dividend yields over a one-year period ending March 31, 2025 indicate that SRI income returns at certain risk levels have been lower than those of the Core portfolio. Oil and gas companies like BP, Chevron, and Exxon, for example, currently have relatively high dividend yields, and excluding them from a given portfolio can cause its income return to be lower. Of course, future dividend yields are uncertain variables and past data may not provide accurate forecasts. Nevertheless, lower dividend yields can be a factor in driving total returns for SRI portfolios to be lower than those of Core portfolios. Comparison of Dividend Yields Source: Bloomberg, Calculations by Betterment for one year period ending March 31, 2025. Dividend yields for each portfolio are calculated using the dividend yields of the primary ETFs used for taxable allocations of Betterment’s portfolios as of March 2025. Conclusion Despite the various limitations that all SRI implementations face today, Betterment will continue to support its customers in further aligning their values to their investments. Betterment may add additional socially responsible funds to the SRI portfolios and replace other ETFs as the investing landscape continues to evolve. -
The Goldman Sachs Smart Beta portfolio methodology
The Goldman Sachs Smart Beta portfolio methodology Jun 18, 2026 12:00:00 AM The Goldman Sachs Smart Beta portfolio is meant for investors who seek to outperform a market-cap portfolio strategy in the long term, despite periods of underperformance. Our Smart Beta portfolio sourced from Goldman Sachs Asset Management helps meet the preference of our customers who are willing to take on additional risks to potentially outperform a market capitalization strategy. The Goldman Sachs Smart Beta portfolio strategy reflects the same underlying principles that have always guided the core Betterment portfolio strategy—investing in a globally diversified portfolio of stocks and bonds. The difference is that the Goldman Sachs Smart Beta portfolio strategy seeks higher returns by moving away from market capitalization weightings in and across equity asset classes. What is a smart beta portfolio strategy? Portfolio strategies are often described as either passive or active. Most index funds and exchange-traded funds (ETFs) are categorized as “passive” because they track the returns of the underlying market based on asset class. By contrast, many mutual funds or hedge fund strategies are considered “active” because an advisor or fund manager is actively buying and selling specific securities to attempt to beat their benchmark index. The result is a dichotomy in which a portfolio gets labeled as passive or active, and investors infer possible performance and risk based on that label. In reality, portfolio strategies reside within a plane where passive and active are just two cardinal directions. Smart beta funds, like the ones that were selected for this portfolio, seek to achieve their performance by falling somewhere in between extreme passive and active, using a set of characteristics, called “factors1,” with an objective of outperformance while managing risk. The portfolio strategy also incorporates other passive funds to achieve appropriate diversification. This alternative approach is also the reason for the name “smart beta.” An analyst comparing conventional portfolio strategies usually operates by assessing beta, which measures the sensitivity of the security to the overall market. In developing a smart beta approach, the performance of the overall market is seen as just one of many factors that affects returns. By identifying a range of factors that may drive return potential, we seek the potential to outperform the market in the long term while managing reasonable risk. When we develop and select new portfolio strategies at Betterment, we operate using five core principles of investing: Personalized planning A balance of cost and value Diversification Tax optimization Behavioral discipline The Goldman Sachs Smart Beta portfolio strategy aligns with all five of these principles, but the strategy configures cost, value, and diversification in a different way than Betterment’s Core portfolio. In order to pursue higher overall return potential, the smart beta strategy adds additional systematic risk factors that are summarized in the next section. Additionally, the strategy seeks to achieve global diversification across stocks and bonds while overweighting specific exposures to securities which may not be included in Betterment’s Core portfolio. Meanwhile, with the smart beta portfolio, we’re able to continue delivering all of Betterment’s tax-efficiency features, such as tax loss harvesting and Tax Coordination. Investing in smart beta strategies has traditionally been more expensive than a pure market cap-weighted portfolio. While the Goldman Sachs Smart Beta portfolio strategy has a far lower cost than the industry average, it is slightly more expensive than the core Betterment portfolio strategy. Because a smart beta portfolio incorporates the use of additional systematic risk factors, we typically only recommend this portfolio for investors who have a high risk tolerance and plan to save for the long term. Which “factors” drive the Goldman Sachs Smart Beta portfolio strategy? Factors are the variables that drive performance and risk in a smart beta portfolio strategy. If you think of risk as the currency you spend to achieve potential returns, factors are what determine the underlying value of that currency. We can dissect a portfolio’s return into a linear combination of factors. In academic literature and practitioner research (AQR), factors have been shown to drive historical returns. These analyses form the backbone of our advice for using the smart beta portfolio strategy. Factors reflect economically intuitive reasons and behavioral biases of investors in aggregate, all of which have been well studied in academic literature. Most of the equity ETFs used in this portfolio are Goldman Sachs ActiveBetaTM, which are Goldman Sach’s factor-based smart beta equity funds. Stocks are scored according to four factors where the highest scoring companies have greater weighting. The weights are then constrained to be in-line with the market. These factors include: Good Value When a company has solid earnings (after-tax net income), but has a relatively low price (i.e., there’s a relatively low demand by the universe of investors), its stock is considered to have good value. Allocating to stocks based on this factor gives investors exposure to companies that have high growth potential but have been overlooked by other investors. High Quality High-quality companies demonstrate sustainable profitability over time. By investing based on this factor, the portfolio includes exposure to companies with strong fundamentals (e.g., strong and stable revenue and earnings) and potential for consistent returns. Low Volatility Stocks with low volatility tend to avoid extreme swings up or down in price. What may seem counterintuitive is that these stocks also tend to have higher returns than high volatility stocks. This is recognized as a persistent anomaly among academic researchers because the higher the volatility of the asset, the higher its return should be (according to standard financial theory). Low-volatility stocks are often overlooked by investors, as they usually don’t increase in value substantially when the overall market is trending higher. In contrast, investors seem to have a systematic preference for high-volatility stocks based on the data and, as a result, the demand increases these stocks’ prices and therefore reduces their future returns. Strong Momentum Stocks with strong momentum have recently been trending strongly upward in price. It is well documented that stocks tend to trend for some time, and investing in these types of stocks allows you to take advantage of these trends. It’s important to define the momentum factor with precision since securities can also exhibit reversion to the mean—meaning that “what goes up must come down.” The Goldman Sachs Smart Beta portfolio also targets a small operational cash allocation in taxable accounts, health savings accounts, and individual retirement accounts (IRAs). How can these factors lead to future outperformance? In specific terms, the factors that drive the smart beta portfolio strategy—while having varying performance year-to-year relative to their market cap benchmark—have potential to outperform their respective benchmarks when combined. You can see an example of this in the chart of yearly factor returns for US large cap stocks below. You’ll see that the ranking of the four factor indexes varies over time, rotating outperformance over the S&P 500 Index in nearly all of the years. Performance Ranking of Smart Beta Indices vs. S&P 500 Why invest in a smart beta portfolio? As we’ve explained above, we generally only advise using Betterment’s choice smart beta strategy if you’re looking for a more tactical strategy that seeks to outperform a market-cap portfolio strategy in the long term despite potential periods of underperformance. For investors who fall into such a scenario, our analysis, supported by academic and practitioner literature, shows that the four factors above may provide higher return potential than a portfolio that uses market weighting as its only factor. While each factor weighted in the smart beta portfolio strategy has specific associated risks, some of these risks have low or negative correlation, which allow for the portfolio design to offset constituent risks and control the overall portfolio risk. Of course, these risks and correlations are based on historical analysis, and no advisor could guarantee their outlook for the future. An investor who elects the Goldman Sachs Smart Beta portfolio strategy should understand that the potential losses of this strategy can be greater than those of market benchmarks. In the year of the dot-com collapse of 2000, for example, when the S&P 500 dropped by 10%, the S&P 500 Momentum Index lost 21%. Given the systematic risks involved, we believe the evidence that shows that smart beta factors may lead to higher expected return potential relative to market cap benchmarks, and thus, we are proud to offer the portfolio for customers with long investing horizons. 1Factors, as applied in investing, can mean different things. In the context of asset allocation, factors are drivers of return within broader asset classes used as a lens to uncover return potential and minimize risk. The Goldman Sachs Smart Beta portfolios examine market capitalization, rates, emerging markets, credit, equity style, commodities and momentum to seek to avoid taking unnecessary risk while pursuing the best opportunities to drive portfolio returns. -
Three blockbuster IPOs are launching. Here's when they'll land in your portfolio.
Three blockbuster IPOs are launching. Here's when they'll land in your portfolio. Jun 15, 2026 5:20:03 PM SpaceX, OpenAI, and Anthropic are going public and selling billions in stock. Before you chase the buzz, read up on the backstory. Key takeaways Several high-profile, private companies are going public in 2026, headlined by SpaceX, OpenAI, and Anthropic. Many major indexes will fast-track these companies for inclusion within weeks of their debuts. The S&P 500, however, requires a year of seasoning and strict profitability criteria. Betterment customers have multiple on-ramps to invest in them via both automated and self-directed investing. IPO excitement can inflate opening prices, which makes it hard to come out ahead. There's a case for letting the market do its stress-testing first. As these mega-cap companies join an already tech-heavy market, diversification across sectors and geographies matters more than ever. The aerospace juggernaut SpaceX smashed records with its recent initial public offering (IPO), turning a slice of the once-private company's trillions in theoretical valuation into real, tradeable stock. It raised plenty of capital—and questions—in the process, so let’s dive in and sort through what it all means for everyday investors like yourself. Wait, what’s an IPO again? An IPO is when a privately-held company goes public, selling ownership in the open market as a way to both raise money and give earlier investors a chance to “exit” and realize a return. A trio of splashy technology IPOs headline this year: not just SpaceX, but two of the biggest brand names in AI: OpenAI and Anthropic. Both are targeting IPOs for later in 2026. Taken altogether, the three could be worth more than $3 trillion, though only a portion of that value will initially come to market. That public stock would still be substantial, so the companies and their underwriters are being deliberate about how many shares they offer upfront. Before we get to how many, however, let's look at the more pressing question: how soon might these newly-public companies show up in your portfolio? Indexes are fast-tracking the trio for inclusion, with one BIG exception Stock indexes are simply lists, or put another way, they’re the ingredient lists that index funds base their allocations on. These index funds can provide a cheaper and easier way to diversify, letting you passively invest with the aim of matching market returns. But the lists themselves aren’t open-sourced. They’re strictly owned and operated, with specific rules for how quickly new businesses on the block can gain entry. Mega-cap companies (those with valuations of $200 billion or more) are testing the limits of those rules. These tech companies could make their way into many notable indexes within weeks, if not days, of going public—including the Russell 1000, with $2 trillion of funds tied to it, and the CRSP US Large Cap Index, with $1.8 trillion indexed. But the mother of all indexes, the S&P 500, isn’t budging. It represents nearly half the value of all the investable stocks in the world, and nearly $12 trillion worth of funds follow its script. And those big institutional investors aren’t keen on passively buying brand new stocks whose valuations haven’t been stress-tested. The S&P 500 has strict profitability rules companies must pass before being eligible for inclusion, rules created after the dot-com bubble, and a 12-month waiting or “seasoning” requirement to boot. So how does all of this translate into your investing? Betterment customers can set their own launch window These IPO darlings will take a while to show up in the S&P 500, but Betterment customers still have several avenues for investing in them sooner rather than later. Most of our expert-built, curated portfolios—Value Tilt, Innovative Tech, Socially Responsible Investing, and Goldman Sachs Smart Beta—utilize index funds that have a higher likelihood of listing these companies within weeks of them going public. Our Core portfolio, on the other hand, primarily gets its U.S. stock exposure through funds that track S&P indexes, so inclusion will come farther down the road. If you self-direct your investing at Betterment, you can buy applicable funds themselves, or in many cases you can buy the companies directly as single stocks shortly after they begin trading. And in the coming weeks, we’ll also be introducing Custom portfolios, which pair the flexibility of self-directed investing with the power of our automation and tax-saving technology. This new investment option will replace our Flexible portfolio and let investors slot those funds or single stocks into their portfolios themselves. All this being said, trading in these freshly-minted equities often comes with heightened volatility and additional risk. The buzz and buildup to their IPOs can drive up their opening prices, making it tough to exceed expectations and net out in the positive. Morningstar, for one, believes SpaceX’s initial offering was overvalued. There's no shame in waiting for these companies to organically work their way into a globally-diversified portfolio. In fact, there's a strong argument for it. By then, you’d be buying at a price the market has had time to test, and you’d own them as part of a portfolio that doesn’t hinge on any single rocket launch. The tech-centric stock market is about to get more techy Diversifying across continents and industries is all the more important given the increasing concentration of the stock market. Technology already accounts for more than 44% of the S&P 500, and the arrival of several mega-cap tech and tech-adjacent IPOs in 2026 could push that share even higher. Fortunately, the full value of these companies won’t be going public. They’ll make a portion of shares available to the public in what’s known as “float,” with the remaining still owned by company insiders, employees, and the angel investors and venture capitalists who helped fund early stages of growth. SpaceX, for example, offered “only” $85.7 billion of shares in its IPO. It’s this public stock that informs how big a slice of indexes they’ll make up, and that number is still sizable. Increased concentration in any single sector, especially one driven by a relatively small number of mega-cap names, can amplify both gains during favorable market conditions and drawdowns during corrections. But that’s why Betterment exists. We’re here to do the heavy lifting of asset allocation, and help you sleep a little more soundly, no matter what starry-eyed headlines these IPOs generate. -
Big traders have a built-in edge. So we engineered one for everyone.
Big traders have a built-in edge. So we engineered one for everyone. Jun 9, 2026 12:33:56 PM Individual investors have long faced structural disadvantages. Here's how Betterment's trading team and custom-built platform help close that gap. Key takeaways The trading system has long been tilted in favor of large institutional investors. Betterment's custom-built trading platform was designed to change that, harnessing the collective power of our customers. We pool your orders with other customers' to unlock the kind of bulk-order pricing big trading desks take for granted. The result: Betterment customers, whether you self-direct or automate your investing, get a fairer shake in the market. For everyday investors, the mechanics of trading haven’t always resulted in a fair fight. That’s because markets tend to reward size and speed. Large institutional investors—think hedge funds, pension funds, endowments—trade in enormous volume. And when you routinely show up with big trading orders, you tend to get preferential treatment. Those privileges get even bigger during bouts of volatility, or when trading activity is thin and buyers and sellers are harder to find. If you're a solo investor wading into those waters, you're swimming upstream. Betterment’s trading platform, however, was designed to harness the collective power of our customers. Here's how. We set price guardrails on your trade, so market chaos doesn’t cost you One of the key aspects of our trading execution methodology is the type of order we use to execute your trades. In many cases, Betterment uses marketable limit orders, which set a price ceiling (or floor) for every trade. They're designed to execute or “fill” quickly, but won't do it at a price worse than the limit. It's a guardrail that keeps the market's momentary chaos from working against you. Limit orders are one of the tools we use in pursuing "best execution," a regulatory standard that requires us to seek the most favorable terms reasonably available for your trade. Your trade packs a bigger punch—because it's not alone It’s a familiar concept for anyone who’s stepped foot in a Costco. When a seller knows you're ordering at volume, they're more motivated to give you their best price. The same logic applies in trading. Betterment aggregates customers' orders, combining similar buys (or sells) of the same security before sending them to market as a single, larger order. The crucial cutoff is generally 100 shares or more of any given stock or fund. These orders are known as “round” lots, the standard unit of trading that exchanges and market makers prioritize. Any order smaller than 100 shares, on the flip side, is generally considered an “odd” lot. The problem is solo investors struggle to come up with nice “round” lots on their own, and they end up paying more as a result. How much more? A 2021 analysis of more than 3 billion U.S. equity trades found that odd lot orders, even those falling just one share short of 100, experienced roughly 10% less price improvement than round lots. For a popular, heavily-traded fund like VTI, that can amount to thousands of dollars in lost gains over decades.1 1Example for illustrative purposes only, based on internally-derived simulations that reflect market behavior consistent with the cited peer-reviewed research. It does not represent actual performance. By banding your order together with the similar orders of other Betterment customers, we cross the round-lot threshold more often, which generally leads to better pricing. It’s important to note, however, that we don't delay your trade to chase a round lot. We aggregate when client orders naturally line up, and execute when they don't. Less predictable trading windows help you stay one step ahead High-frequency traders have made an industry of being first. By watching for signals in the market, like a sudden uptick in buy orders for a particular stock, they can race in ahead of you, buy what you were about to buy, and attempt to flip it for a profit before your trade even clears. It's exactly the sort of systemic disadvantage our custom-built trading technology works to help minimize. When orders are sent to market the instant they're placed, they can signal intent to anyone watching. Betterment, by contrast, batches orders into scheduled trade windows throughout the day, and we vary those windows across most of our trading activity. No predictable pattern means no easy target. This also works hand-in-hand with our bundling strategy above: the windows give us time to aggregate orders before sending them to market, making round-lot thresholds more attainable. There are always exceptions, of course. When timing is critical, like with day-end orders, we execute whatever lots are ready, odd or round, rather than wait for the next day. Prices can and do move while the market is closed, which is why we strive to process certain orders before the bell.2 Trade with confidence at Betterment Showing up to market as a solo investor can be rough. You’re a small fish in a very big pond. That’s where Betterment comes in. Whether you self-direct your investing or enlist our automated tech for help, you benefit from our custom-built trading platform. It pools your trades whenever possible, sets price guardrails, and chooses the moment deliberately. All so your trade gets a fairer shake, and you get more freedom to invest as you see fit. -
Can a portfolio be too simple?
Can a portfolio be too simple? Jun 9, 2026 12:00:00 AM Total market funds offer simplicity, but by unbundling asset classes—and adding Betterment’s automation—you can make your money work harder. Key takeaways Single-fund portfolios are easy to build, but they’re harder to optimize for taxes and costs. Using multiple funds adds the flexibility to fine-tune allocations and unlock savings. Betterment’s automation and expert-built portfolios give you the best of both worlds: easy to invest in, and built to work harder. If you’re looking to build long-term wealth, you could do worse than investing in one or two low-cost, globally-diversified total market funds. But you could potentially do better—and spend less of your limited bandwidth—by using a few more pieces and putting our technology to work in your favor. That’s the value of Betterment’s automated investing and expert-built portfolios, and it begins with (surprise!) tax optimization. Harvesting losses for tax wins, and putting your assets in the right place Targeting more than a date Splitting hairs on fund fees, so customers can save millions Harvesting losses for tax wins, and putting your assets in the right place Tax-loss harvesting can help give your taxable investing an edge, and it happens when we sell and replace similar assets using available funds. The downside of a total market fund, however, is you have to wait for the entire fund to experience a loss. If only one piece of it dips, you can’t unbundle the assets and harvest that specific piece. It’s sell all, or sell nothing. That’s a big reason why we switched from using a single fund for U.S. stocks in our Betterment-built portfolios, opting instead for three separate funds representing small, medium, and large-sized U.S. companies. If one of them presents a harvesting opportunity, we can swap it for a similar alternative. The second area where larger fund lineups shine is asset location, or strategically divvying up your portfolio’s assets among traditional, Roth, and/or taxable accounts. Stocks with the highest potential for growth, for example, are often better-suited for traditional accounts. Let them grow tax-free, the thinking goes, then settle up with Uncle Sam when you’re retired and more likely to be in a lower tax bracket. Our mathematically-rigorous spin on asset location is called Tax Coordination, and it’s yet another way our automated investing helps you keep more of what you earn. To start taking advantage of it, simply open any combination of the three account types above and follow a few easy steps. Targeting more than a date One of the most common single-fund options for retirement savings are target date funds. They date back to the 90s and became the default option in many 401(k) plans starting in the late 2000s. The growth of target date funds has been a good thing for investors, helping move the industry toward lower-cost, automated investing. Prior to their arrival, advisors had to manually adjust the asset allocations or “glide paths” of portfolios over time. Similar to total market funds, however, the bundling of target date funds brings with it some constraints. The first constraint is their relative lack of choice. Say you were born in 1988 and are targeting a traditional retirement age of 62. Most target date fund managers give you one option—the 2050 fund. Our automated investing, on the other hand, gives you more than a handful of portfolios to choose from, including ones tailored for social responsibility and innovation. More funds also creates more levers to fine-tune your exposure, helping manage risk in all sorts of situations. Take bond-heavy portfolios as an example. Rising interest rates can erode their value, so we dial up their exposure to short-term corporate debt and U.S. Treasuries specifically to help hedge against that risk. Splitting hairs on fund fees, so customers can save millions The relatively high cost of target date funds has been trending downward, and many total market funds can be found for expense ratios of less than 0.1%. But we can squeeze out even more savings by splitting a portfolio up and shopping for better deals. A single one hundredth of a percentage point in fund fees (what’s referred to as a “basis point” or “bip” in investing lingo) may not sound like much, but we owe it to our customers to make every one count. You could pay 6 basis points (0.06%), for example, for a total world stock fund like VT. Or you could pay one-third of that for your U.S. stock allocation by breaking it up into three funds (SPYM, SPMD, and SPSM) like we do with our Core portfolio and others. Using our customers’ nearly $20 billion worth of U.S. stocks as an example, that would amount to roughly $7.6 million in combined savings each year. Flexibility to stretch your investing dollars even farther A simple portfolio can be a great place to start, but it’s not always where your money works hardest. By strategically using a few more funds, we can sprinkle tax advantages on more of your investing, optimize across account types, and potentially unlock even more cost savings. All automatically. You get the simplicity you want, but with our tech doing the heavy lifting behind the scenes. -
Inside the investing kitchen, part 1
Inside the investing kitchen, part 1 Jun 8, 2026 12:00:00 AM The recipe for a better portfolio, and the science behind a safer nest egg. Jamie Lee isn’t a Top Chef, but he knows his way around the kitchen. He dabbles in sous vide with the help of a sous chef (his 6-year-old daughter). He loves smoking salmon low and slow on a pair of pellet grills. And in some ways, his day job on the Betterment Investing team resembles the culinary world as well. He and his teammates work in a test kitchen of sorts, defining and refining the recipes for our low-cost and globally-diversified portfolios. They size up ingredients, pair flavors, and thoughtfully assemble the courses of each “meal.” All in service of customers with varying appetites for risk. It's highly-technical work, but we wouldn't be Betterment if we didn't make our methodologies as accessible as possible. So whether you're kicking the tires on our services, or you're already a customer and simply curious about the mechanics of your money machine, come along for a three-part, behind-the-scenes look at how we cook up a better portfolio. Here in part 1, we'll explore how we allocate your investing at a high level. In part 2, we'll zoom in to our process for selecting specific funds. And in part 3, we'll show you how we handle thousands of trades each day to keep our customers’ portfolios in tip-top shape. The science behind a safer nest egg Betterment customers rely on Jamie and team to do the heavy lifting of portfolio construction. They distill handfuls of asset classes, a hundred-plus risk levels, and thousands of funds into a simple yet eclectic menu of investment options. This process applies to the invested (non-cash) portion of our portfolios, and underpinning much of it is something called Modern Portfolio Theory, a framework developed by the late American economist Harry Markowitz. The theory revolutionized how investors think about risk, and led to Markowitz winning the Nobel Prize in 1990. Diversification lies at the heart of Modern Portfolio Theory. The more of it your investing has, the theory goes, the less risk you're exposed to. But that barely scratches the surface. One of the meatiest parts of building a portfolio (and by extension, diversifying your investing) is how much weight to give each asset class, also known as asset allocation. Broadly speaking, you have stocks and bonds. But you can slice up the pie in several other ways. There’s large cap companies or less established ones. Government debt or the corporate variety. And even more relevant as of late: American markets or international. Jamie came of age in South Korea during the late 90s. Back here in the States, the dot-com bubble was still years away from popping. But in South Korea and Asia more broadly, a financial crisis was well underway. And it changed the trajectory of Jamie’s career. His interest in and application of math shifted from computer science to the study of markets, and ultimately led to a PhD in statistics. Jamie Lee (right) helps optimize the weights of asset classes in Betterment portfolios. For Jamie, the interplay of markets at a global level is fascinating. So it’s only fitting that when optimizing asset allocations for customers, Jamie and team start with the hypothetical "global market portfolio," an imaginary snapshot of all the investable assets in the world. The current value of U.S. stocks, for example, represents about two-thirds the value of all stocks, so it's weighted accordingly in the global market portfolio. These weights are the jumping off point for a key part of the portfolio construction process: projecting future returns. Reverse engineering expected returns “Past performance does not guarantee future results.” We include this type of language in all of our communications at Betterment, but for quantitative researchers, or “quants,” like Jamie, it’s more than a boilerplate. It’s why our forecasts for the expected returns of various asset classes largely aren't based on historical performance. They're forward-looking. "Past data is simply too unreliable," says Jamie. "Look at the biggest companies of the 90s; that list is completely different from today.” So to build our forecasts, commonly referred to in the investing world as Capital Market Assumptions, we pretend for a moment that the global market portfolio is the optimal one. Since we know roughly how each of those asset classes performs relative to one another, we can reverse engineer their expected returns. This robust math is represented by a deceivingly short equation—μ = λ Σ ωmarket—which you can read more about in our full portfolio construction methodology. From there, we simulate thousands of paths for the market, factoring in both our forecasts and those of large asset managers like BlackRock to find the optimal allocation for each path. Then we average those weights to land on a single recommendation. This “Monte Carlo" style of simulations is commonly used in environments filled with variables. Environments like, say, capital markets. The outputs are the asset allocation percentages (refreshed each year) that you see in the holdings portion of your portfolio details. At this point in the journey, however, our Investing team's work is hardly finished. They still need to seek out some of the most cost-effective, and just plain effective, funds that give you the intended exposure to each relevant asset class. For this, we need to head out of the test kitchen and into the market. So don’t forget your tote bag. -
The behavioral case for bonds
The behavioral case for bonds Jun 4, 2026 12:00:00 AM How bonds can build a buffer that makes your portfolio more resilient, and you more likely to stay invested Key takeaways Bonds are loans investors make to companies, governments, and other entities in exchange for interest. Although their historical returns are lower than stocks, their relative stability makes them an ideal buffer during bouts of market volatility. Bonds can help investors stay in the game and preserve capital for the next market recovery. Betterment makes it simple to mix them into your portfolio now and adjust along the way. When most of us think about investing, we think about the flashy headlines of the stock market, the ups and downs of brand names and the companies behind them. Bonds, by contrast, can feel boring. But they’re often the unsung heroes of a well-balanced portfolio. They help smooth out your investing journey, making it more likely you stay in the wealth-building game. So, what exactly is a bond? At its simplest, a bond is a glorified loan, but one that you make, not the other way around. You’re lending your money to an entity (usually a company or government) for a set period, and in exchange, they promise to pay you back the full amount on a specific date, plus a little extra interest (aka “yield”) along the way. Bonds commonly break down along two lines: Investment-grade bonds — These are issued by less risky, more creditworthy entities and offer lower yields as a result. The U.S. government is one of the biggest players here—issuing tens of billions in Treasury bonds—but corporate bonds also play a role. High-yield bonds — Bonds issued by riskier, less creditworthy players (both corporate and government) and carrying higher yields in turn. These types of bonds are often under-represented in funds that track a pre-set list of bonds, meaning there’s more potential for higher returns with the right active management. For most of the 2010s, interest rates were stuck near zero, which meant bonds of all kinds weren't paying much. But the landscape has shifted since the pandemic. Since then, the "boring" part of your portfolio is actually working quite hard, offering yields that look a lot more attractive than they used to. Why bonds matter, regardless of your goal’s timeline If you’re in your 20s or 30s, you may think, “I’ve got 30 years to grow my money. Why not just go 100% stocks?” It’s not the craziest idea. Over longer periods, stocks generally outperform bonds. But investing isn't just a math problem; it's a psychology problem. The real danger to your wealth isn't a market dip—it's you hitting the "sell" button during a market dip because the choppy waters feel like too much to bear. Bonds can help calm the storm in this sense. When the stock market has a bad week (or a bad year), they tend to hold more of their value, or even gain in value. They also generally continue to pay out interest. This in theory means your overall portfolio experiences smaller dips, and it’s a lot easier to stay invested when your portfolio is down 15% instead of 30%. Bonds can also help preserve your portfolio’s precious capital, meaning there’s more fuel for the fire as stocks recover and grow beyond their pre-dip levels. This is why our allocation advice for even the longest of timelines still includes some bonds. Putting bonds into practice (and your portfolio) So how do you actually "do" bond investing without spending your weekends reading government balance sheets? You shouldn’t have to be an expert to benefit from a sophisticated bonds strategy. That’s why most of our portfolios include a globally-diversified mix of both stocks and bonds*, with bond allocations that can automatically increase as your goal’s target date nears. *Target investments, actual holdings will vary. You can also manually dial your amount of bonds up or down at any time—we’ll even preview the potential tax impact of the changes you’re considering. In certain cases, one of our portfolios made up primarily of bonds may make even more sense. For investors looking to generate income (e.g. retirees), for example, we offer Target Income built with BlackRock. And for those with incomes falling in the 32% tax bracket or higher, we offer the Goldman Sachs Tax-Smart Bonds portfolio. It’s personalized based on customers’ unique tax situations and focuses on municipal bonds issued by state and local governments, which often offer tax-free interest at the federal level. The bottom line on bonds Bonds are rarely trendy, but their strong track record of stability can help cushion the chaos when market volatility hits next. Betterment’s lineup of stock and bond portfolios make it easy to mix some into your investing today, then adjust as you go. Because your right amount of bonds is whatever helps you stay invested. -
Three ways it can pay to automate your investing
Three ways it can pay to automate your investing Jan 30, 2026 6:00:00 AM Our managed offering adds value beyond a DIY approach. Here’s how. Key takeaways Portfolio construction is just the beginning. Betterment’s automated investing is designed to help you manage risk, maximize returns, and minimize leg work. Tax-smart features help you keep more of what you earn. Fully-automated Tax Coordination and tax-loss harvesting seek out efficiencies hard to replicate by hand. Navigation helps keep your goals on track. Automated rebalancing, effortless glide paths, and recurring deposits make it easier to stay the course through market ups and downs. Peace of mind is part of the return. Automation frees up time and headspace, letting you live your life instead of worrying about your portfolio. With the arrival of self-directed investing at Betterment, you can choose from thousands of individual stocks and ETFs on your own, including the very same funds we research and select for our curated portfolios. So if you can now buy the same low-cost investments, why pay someone (i.e., us) to manage them for you? It’s a fair question, and to help answer it, it helps to understand why our portfolio construction is just the beginning of the story. It's not just the Betterment portfolio you see today, but the one you see tomorrow (and in the weeks, months, and years that follow) that captures the full value of our expertise and technology. The ongoing optimization and evolution of your portfolio, in other words, is where our automated investing really shines. Sometimes the benefits are tangible. Sometimes they’re emotional. But regardless of how you frame it, we’re constantly working in the background to deliver value in three big ways. Tax savings: keeping more of what you earn Navigation: keeping your investing on-track Calm: keeping your sanity—and your spare time 1. Tax savings: keeping more of what you earn One of the most reliable ways to increase your returns is lowering the taxes owed on your investments. And here's the first way Betterment’s managed portfolios can pay off. Our trading algorithms take tax optimization to a level that’s practically impossible to replicate on your own. Take our Tax Coordination feature, which uses the flexibility of our portfolios to locate assets strategically across Betterment traditional IRAs/401(k)s, Roth IRAs/401(k)s, and taxable accounts. This mathematically-rigorous spin on asset location can help more of your earnings grow tax-free. Then there’s our fully-automated tax-loss harvesting, a feature designed to free up money to invest that would've otherwise gone to Uncle Sam. Our technology regularly scans accounts to identify harvesting opportunities, then goes to work. It’s how we harvested nearly $60 million in losses for customers during the tariff-induced market volatility of Spring 2025. Betterment does not provide tax advice. TLH is not suitable for all investors. Learn more. It’s also a big reason why nearly 70% of customers using our tax-loss harvesting feature had their taxable advisory fee covered by likely tax savings.1 And with the upcoming addition of direct indexing to Betterment’s automated investing, our harvesting capabilities will only continue to grow. 1Based on 2022-2023. Tax Loss Harvesting (TLH) is not suitable for all investors. Consider your personal circumstances before deciding whether to utilize Betterment’s TLH feature. Fee coverage and estimated tax savings based on Betterment internal calculations. See more in disclosures. 2. Navigation: keeping your investing on-track It’s easy to veer off-course when managing your own investing. Life happens, calendars fill up, and the next thing you know, your portfolio starts to drift. When you pay for automated investing, however, you not only get our guidance upfront, you benefit from technology designed to get you to your destination with less effort. As markets ebb and flow, for example, we automatically rebalance your portfolio to maintain your desired risk level. And the “glide path” that automatically lowers your risk as your goal nears? It just happens in eligible portfolios. No research or calendar reminders needed. Our management also helps steer your investing toward a time-tested path to long-term wealth. Most of our portfolios are globally diversified so you take advantage when overseas markets outperform. And we encourage recurring deposits so you buy more shares when prices are low. Recent research by Morningstar helps quantify the value of this “dollar-cost averaging” approach. They found investors lost out on roughly 15% of the returns their funds generated due in large part to jumping in and out of the market. Betterment customers using recurring deposits, meanwhile, earned nearly ~4% higher annual returns.2 It turns out it’s easier to stay the course with a little help. 2Based on Betterment’s internal calculations for the Core portfolio over 5 years. Users in the “auto-deposit on” groups earned an additional 0.6% over the last year and 1.6% annualized over 10 years. See more in disclosures. 3. Calm: Keeping your sanity—and your spare time Our automation can save you time—two hours for each rebalance alone3—but the value of automating your investing is more than just time saved. It’s quality time spent. How much of your finite energy, in other words, are you spending worrying about your money? We can’t erase all of your anxiety, but our team and our tech can empower you to build wealth with confidence and ease, with an emphasis on the ease. 3Based on internal data for a client with one account subject to Betterment’s TaxMin methodology and no other tax features enabled. Betterment will not automatically rebalance a portfolio until it meets or exceeds the required account balance. Between market volatility and a constant barrage of scary headlines, the world is stressful enough right now. There’s little need to add portfolio optimization and upkeep to the list. That is, of course, unless you enjoy it. But many of us don’t. The majority of Betterment customers we surveyed said they hold most of their assets in managed accounts, with self-directed investing serving as a side outlet for exploration. That’s why we offer both ways to invest at Betterment. The payoff is personal Investing performance and price are often measured down to the hundredth of a percentage point. That’s “zero point zero one percent” (0.01%), also known as a “basis point" or "bip" for short. Here at Betterment, it’s our mission to make every one of the 25 bips we most commonly charge worth it. We measure our portfolio’s performance after those fees, so you see what you’ve really earned. And we don’t stop there. With direct indexing and fully paid securities lending coming soon to automated investing, you’ll get even more ways to make your money work harder.
