Inside the investing kitchen, part 1 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, high-performing, 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 (coming soon), we'll zoom in to our process for selecting specific funds. And in part 3 (also coming soon), 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. And underpinning much of this process 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. 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 Hypothetical portfolio; for illustration only 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.

Four ways we help trim your tax bill And why these "invisible" wins matter more than you may think. As investors, we tend to focus most on what we can see. Things like portfolio makeup, and the returns generated by those investments. No less important, however, are the less obvious things, like the taxes you never paid in the first place because of technology that quietly runs in the background. You may only think about taxes once a year, but here at Betterment, every day is Tax Day. This sort of year-round tax optimization sounds boring, but believe us, it makes a difference. Taxes can steadily eat away at your returns over the years. So any advisor worth their salt should take taxes seriously and minimize them as much as possible. These “invisible” wins are hard to spot in the moment, so let’s shine a light on them now. Here are four sophisticated ways we buy, sell, and hold your shares, all in the name of trimming your tax bill. Choosing which assets go where – Our Tax Coordination feature helps shield high-growth assets in the most tax-efficient account types. Rebalancing wisely – We take advantage of any existing cash flows to help minimize capital gains taxes while rebalancing your portfolio. Choosing which taxable shares to sell (or donate) – Our TaxMin technology helps minimize short-term capital gains taxes. Harvesting losses – When your taxable investments dip below their initial purchase price, we jump on the opportunity to “harvest” the theoretical loss and potentially lower your future tax bill. 1. Choosing which assets go where From a tax perspective, you have three main account types at your disposal when saving for retirement: Tax-deferred (traditional IRAs, 401(k)s, etc.), where taxes are paid later. Tax-exempt (Roth IRAs, 401(k)s, etc.), where taxes are paid now. Taxable, where taxes are paid both now and later. Because of their different tax treatments, certain types of investments are a better fit for certain accounts. Interest from bonds, for example, is typically taxed at a higher rate than stocks, so it often makes sense to keep them away from taxable accounts. This sorting of asset types based on tax treatments, rather than divvying them up equally across accounts, is known as asset location. And our fully-automated, mathematically-rigorous spin on it is called Tax Coordination. When Tax Coordination is turned on, the net effect is more of your portfolio's growth is shielded in a Roth account, the pot of money you crucially don't pay taxes on when withdrawing funds. To learn more about our Tax Coordination feature and whether it’s right for you, take a peek at its disclosure. 2. Rebalancing wisely When the weights of asset classes in your portfolio drift too far from their targets, our technology automatically brings them back into balance. But there's more than one way to accomplish this portfolio rebalancing. You can simply sell some of the assets that are overweight, and buy the ones that are underweight (aka "sell/buy" rebalancing), but that can realize capital gains and result in more taxes owed. So we first take advantage of any available cash flows coming into or out of your portfolio. When you make a withdrawal, for example, we intentionally liquidate overweight assets while striving to minimize your tax hit as much as possible (more on that below). And when you deposit money or receive dividends, we use those funds to beef up underweight assets. 3. Choosing which taxable shares to sell (or donate) Say there's no way around it: you need to sell an asset. Maybe cash flows aren't enough to keep your portfolio completely balanced. Or you’re withdrawing funds for a major purchase. The question then becomes: which specific assets should be sold? The IRS and many brokers follow the simple script of "first in, first out," meaning your oldest assets are sold first. This approach is easier for your broker, and it can avoid more highly-taxed short-term capital gains. But it often misses the opportunity of selling assets at a loss, and harvesting those losses for potential tax benefits. So our algorithms take a more nuanced approach to selecting shares, and we call this technology TaxMin. TaxMin is calibrated to avoid frequent small rebalance transactions and seek tax-efficient outcomes, things like avoiding wash sales and minimizing short-term capital gains. In the case of donating shares, we apply the same logic in reverse, or TaxMax as we call it. That's because when donating shares, it benefits you to choose the ones with the most gains, since any shares bought as a replacement will effectively have a reset tax bill. 4. Harvesting losses Life is full of ups and downs, and your investments are no different. At times, most notably during market downturns, the price of an asset may dip below what you paid for it. Tax loss harvesting takes advantage of these moments, selling taxable assets that fit this bill, then replacing them with similar ones so you stay invested. You can then use those harvested losses to shift taxes you owe now into the future. The strategy doesn’t make sense for everyone, but it can help some investors sprinkle tax advantages on a portion of their taxable investing. And our fully-automated spin on it takes a tax hack once reserved for the wealthy and makes it available to the masses. Happy harvesting. In conclusion, we care a lot about taxes Because it’s one of the most reliable ways to boost your returns. We can’t control the market, but tax laws? Those are set by the IRS and broadcast far and wide. And we can help you navigate them wisely. We wouldn’t be doing our job if we didn’t. So the next time you take a peek at your returns, ask yourself how much of that growth will still be there come tax time. If you’re a Betterment customer, you can rest assured we’re working tirelessly to minimize those tax drags. You may not realize it right away, and rightfully so. Live your life, and leave the tax toiling to us.

With U.S. markets struggling, is now the time to go global? Here’s the case for keeping a little international exposure in your investing. U.S. stocks have been the envy of the world since 2010, generating nearly 4 times the returns of their international counterparts. But since April 2, President Trump’s tariff policies have dragged down U.S. stocks and left investors unnerved. Does this mean the U.S. market is toast? Certainly not, but it does signal a potential shift in foreign investment, which means that if you haven’t already, now may be the time to consider diversifying globally. And we can help on that front. Hello, world. We're here to invest. The U.S. market is big, but it’s not the only game in town. Hundreds of billions of dollars in assets trade hands in international markets each day. It's why the Betterment Core portfolio, built on the idea that more diversification equals less risk, roughly mirrors the relative weights of global markets. Like we mentioned above, the U.S. market has been on an absolute tear the past 15 years, and even more so since 2020. This record winning streak has fueled our home bias, or the tendency for American investors to favor American markets. But history shows a pendulum that typically swings back and forth every 5 to 10 years. International markets outperformed in the 2000s, for example, and they saw a huge spike in the late 80s. So what’s an investor to do? If you're investing for the long term, the odds are good the U.S. market will hit at least one extended rough patch in that time. And in that scenario, a globally-hedged portfolio will very likely smooth out your returns from year to year. We’re seeing this start to play out in 2025, with the Betterment Core portfolio and its global diversification outperforming many common U.S.-only funds. As of 5/2/2025. Betterment Core composite actual time-weighted returns: 10.52% over 1 year, 12.35% over 5 years, and 7.30% over 10 years as of 5/2/2025. Composite performance calculated based on the dollar weighted average of actual client time-weighted returns for the Core portfolio at 90/10 allocation, net fees. Performance not guaranteed, investing involves risk. That being said, diversification is a sliding scale. There is no pass/fail, no good or bad. If you’re looking for a little more international exposure, but not to the extent of one of our pre-built portfolios, you can invest in our Flexible portfolio and tailor your allocation as you see fit. But if you’re less experienced in investing, and simply want an option that requires less work, then let us do the recalibrating for you. We update our pre-built portfolios annually, finetuning our U.S. and international exposures based on the latest long-term projections. We can’t predict when the global tides will turn, but we can make sure you don’t miss out when they do.

How tax loss harvesting turns market losses into tax wins The tax strategy can unlock similar benefits as tax-deferred accounts Tax loss harvesting, or TLH for short, is selling an asset at a loss (which can happen especially during market downturns) primarily to offset taxes owed on capital gains or income. It shifts some of the taxes you might owe now, in other words, into the future. But the key takeaway is this: TLH can take a portion of your taxable investing and effectively turn it into tax-deferred investing. And tax-deferred investing, as we’ll quickly demonstrate, can do wonders for wealth-building. Tax me now or tax me later Take a dollar you would’ve otherwise paid in taxes today. Now invest it wisely. Odds are, it’ll be worth a lot more in the long run, even taking away any taxes you eventually owe. Depending on how your tax situation shakes out over the years, tax-deferred investing can be like Uncle Sam giving you a nearly interest-free loan to invest. This is in large part why tax-deferred accounts like traditional 401(k)s and IRAs come with restrictions. They’re reserved for retirement, namely, and their contributions are capped. But tax loss harvesting opens an entirely new door for tax-deferred investing, along with a few other side benefits. For a few types of investors in particular, it offers tremendous upside. Who TLH benefits the most Let’s start with an important caveat: While TLH offers potential value for most investors, it can be a wash or actually increase your tax burden in certain cases. But for now, let’s focus on three types of investors who can reap some of the biggest rewards from the strategy: The high-income earner Once you’ve offset all of your realized capital gains taxes for a given year, any leftover harvested losses can be used to offset taxes on up to $3,000 of ordinary income. So in the case of high earners, this means trading a high income tax rate for a relatively low long-term capital gains tax rate. The end result is both deferring and discounting your taxes. The steady saver Not only are recurring deposits a great way to start a savings habit, they also produce more harvesting opportunities. That’s because the older an investment, the less likely it drops below its initial purchase price (aka “cost basis”) and can be harvested at a loss. A steady drip of deposits, monthly for example, creates fresh crops of investments for harvesting in the near future. The tax-smart philanthropist A common misconception of tax loss harvesting is that it helps you avoid paying taxes altogether. Believe it or not, however, two scenarios exist in which you actually can cancel out your tax obligation: The first is when you donate shares to charity. As we mentioned earlier, selling and replacing shares as part of a harvest increases their future tax bill. It does this by lowering the shares’ cost basis, or the initial purchase price used to calculate capital gains. If you donate and replace these shares down the road, however, you reset their cost basis to a new, higher level. This effectively wipes out their entire tax bill(!) that had accrued to that point. In the eyes of the IRS, it’s like those capital gains never happened, and it’s one big reason why wealthy investors have long paired TLH with the practice of donating shares. The second scenario is posthumously. At that point, you won’t get a tax break, of course. But any individuals who you leave shares to will, because immediately after your death, the cost basis of your investments similarly “steps up” to their current market value. Your harvest awaits Historically-speaking, tax loss harvesting has been too time-intensive and costly to execute for all but the wealthiest of investors. But technology like ours and the low-cost trading of ETFs have made it a tax strategy for the masses. Take the market volatility of 2025 as an example. In little more than two weeks (March 26-April 10), Betterment harvested nearly $60 million in tax losses for customers. If TLH is right for you, the sooner you open and start contributing to a taxable account, the sooner you can start giving a portion of your taxable investing an edge. If you already have a Betterment taxable account, here’s how to turn on tax loss harvesting.

How we make market downturns less scary And how it can benefit your investing’s bottom line. The recent round of tariffs and trade wars have roiled markets, offering the latest example of investing’s inherent volatility. The fact that market drops do happen, and happen with some regularity, means that managing them is not only possible but paramount. "It's not about whether you're right or wrong," the investor George Soros once quipped. "But how much money you make when you're right, and how much you lose when you're wrong." Mitigating losses, in other words, matters just as much as maximizing gains. And this is true for two important reasons: The bigger the loss, the more tempted you may be to sell assets and lock in those losses. The bigger the loss, the less fuel for growth you have when the market does rebound. Point A is psychological, while Point B is mathematical, so let’s take each one separately. In the process, we’ll explain how we build our portfolios to not only weather the storm, but soak up as many rays as possible when the sun shines again. Smoothing out your investing journey Imagine you’re given a choice of rides: one’s a hair-raising roller coaster, the other a bike ride through a series of rolling hills. Sure, thrill seekers may choose the first option, but we think most investors would prefer the latter, especially if the ride in question lasts for decades. So to smooth things out, we diversify. Owning a mix of asset types can help soften the blow on your portfolio when any one particular type underperforms. Our Core portfolio, for example, features a blend of asset types like U.S. stocks and global bonds. The chart below shows how those asset types have performed individually since 2018, compared with the blended approach of a 90% stocks, 10% bonds allocation of Core. As you can see, Core avoids the big losses that individual asset classes experience on the regular. That’s one reason why through all the ups and downs of the past 15 years, it’s delivered 9% composite annual time-weighted returns1, and that’s after fees are accounted for. 1As of 12/31/2024, and inception date 9/7/2011. Composite annual time-weighted returns: 12.7% over 1 year, 7.9% over 5 years, and 7.8% over 10 years. Composite performance calculated based on the dollar-weighted average of actual client time-weighted returns for the Core portfolio at 90/10 allocation, net of fees, includes dividend reinvestment, and excludes the impact of cash flows. Past performance not guaranteed, investing involves risk. Core’s exposure to global bonds and international stocks has also helped its cause, given their outperformance relative to U.S. stocks year-to-date amidst the current market volatility of 2025. A smoother ride can take your money farther Downside protection is all the more important when considering the “math of losses.” We’ll be the first to admit it’s hard math to follow, but it boils down to this: as a portfolio’s losses rack up, the gains required to break even grow exponentially. The chart below illustrates this with losses in blue, and the gains required to be made whole in orange. Notice how their relationship is anything but 1-to-1. This speaks to the previously-mentioned Point B: The bigger your losses, the less fuel for growth you have in the future. Investors call this “volatility drag,” and it’s why we carefully weigh the risk of an investment against its expected returns. By sizing them up together, expressed as the Sharpe ratio, we can help assess whether the reward of any particular asset justifies its risk. This matters because building long-term wealth is a marathon, not a race. It pays to pace yourself. And yet, there will still be bumps in the road Because no amount of downside protection will get rid of market volatility altogether. It’s okay to feel worried during drops. But hopefully, with more information on our portfolio construction and automated tools like tax loss harvesting, you can ride out the storm with a little more peace-of-mind. And if you’re looking for even more reassurance, consider upgrading to Betterment Premium and talking with our team of advisors.

How socially responsible investing connects your holdings to your heart Learn more about this increasingly-popular category of investing. Socially responsible investing (SRI), also known as environmental, social, and governance (ESG) investing, screens for companies that consider both their returns and their responsibility to the wider world. It’s a growing market for investors, with assets totaling $30 trillion as of 2022. We launched our first SRI portfolio back in 2017, and have since expanded to a lineup of three options: Broad Impact Social Impact Climate Impact All three are globally-diversified, low-cost, and built to help align your investing with your values. So let’s explore a few ways they do that, before tackling a common question about the SRI category in general: performance. How our Social Impact portfolio lifts up underserved groups Social Impact uses the Broad Impact portfolio’s foundation while adding a trio of funds focused on helping underserved groups get on equal footing. There’s $SHE and $JUST, which screen for U.S. companies demonstrating a commitment toward gender and social equality, respectively. Then there’s $VETZ, our latest addition to the portfolio. $VETZ is the first of its kind: a publicly-traded ETF that mainly invests in loans to active and retired U.S. service members, and the survivors of fallen veterans. These types of home and small-business loans have historically helped diversify portfolios, and they also help lower borrowing costs for veterans and their families. And unlike $SHE and $JUST, which are comprised of stocks, $VETZ is an all-bond fund. So even if you have a lower appetite for risk when investing, your SRI portfolio can maintain an exposure to socially responsible ETFs. How the $VOTE fund is shaking up shareholder activism Remember the “G” in ESG? It stands for governance, or how companies go about their business. Do they open up their books when necessary? Is their leadership diverse? Are they accountable to shareholders? On that last front, there’s the $VOTE ETF found in each one of our SRI portfolios. On the surface, it seems like a garden variety index fund tracking the S&P 500. Behind the scenes, however, it’s working to push companies toward positive environmental and social practices. It does this by way of “proxy” voting, or voting on behalf of the people who buy into the fund. Engine No. 1, the investment firm that manages $VOTE, puts these proxy votes to use during companies’ annual shareholder meetings, where individual shareholders, or the funds that represent them, vote on decisions like board members and corporate goals. In 2021, Engine No. 1 stunned the corporate world by persuading a majority of ExxonMobile shareholders to vote for three new board members in the name of lowering the company’s carbon footprint. And it did all this in spite of holding just .02% of the company’s shares itself. Not a bad return on investment, huh? Does SRI sacrifice gains in the name of good? We now stand eye-to-eye with the elephant in the room: performance. Worrying about returns is common regardless of your portfolio, so it’s only natural to question how socially responsible investing in general stacks up against the alternatives. Well, the evidence points to SRI comparing quite well. According to a survey of 1,141 peer-reviewed papers and other similar meta-reviews: The performance of SRI funds has “on average been indistinguishable from conventional investing.” And while the researchers note that it’s “likely that these propositions will evolve,” they also found evidence that SRI funds may offer “downside” protection in times of social or economic crisis such as pandemics. Your socially responsible investing, in other words, is anything but a charity case. Simplifying the socially responsible space Not long ago, SRI was barely a blip on the radar of everyday investors. If you were hip to it, you likely had just two options: DIY the research and purchase of individual SRI stocks Pay a premium to buy into one of the few funds out there at the time Those days are thankfully in the past, because our portfolios make it easy to express your values through your investing. And our team of investing experts regularly seeks out new funds like $VETZ and updated SRI standards that strive to deliver more impact while helping you reach your goals. Check out our full methodology if you’re hungry for more details. And if you’re ready to invest for a better world, we’ve got you covered.
