Avantis ETFs: Evidence-Based Tilts Built for Long-Term Portfolios
You’ve probably noticed Avantis ETFs popping up more in conversations lately. Funds like AVUS and AVUV keep coming up when people talk about adding a thoughtful edge to plain index investing without paying active-fund prices. And honestly, there’s a reason for the interest.
Avantis launched in 2019 as part of American Century Investments. The team behind it includes veterans from Dimensional Fund Advisors, including CIO Eduardo Repetto. They took decades of academic research on what actually drives returns—size, value, and profitability—and turned it into a lineup of low-cost ETFs that anyone can buy. By late 2025 they’d crossed $100 billion in assets. As of May 2026 the whole platform sits near $133 billion across 31 U.S.-listed ETFs. That kind of growth doesn’t happen by accident.
How Avantis ETFs Actually Work

Most broad index funds just buy companies in proportion to their market size and rebalance once or twice a year. Avantis does something different. Their managers look at current prices and real company fundamentals—things like book value and cash-based profitability—to decide which stocks deserve more weight right now.
They overweight smaller companies, those trading at lower valuations relative to book value, and those with stronger profitability. They underweight the expensive, low-profit mega-caps that dominate pure cap-weighted indexes. It’s still broadly diversified—hundreds of holdings in most funds—but the weights shift in a systematic, repeatable way using up-to-date information instead of stale index rules.
The result is a portfolio that aims for higher expected returns over time while keeping turnover reasonable and costs low. It’s not stock-by-stock active management in the old sense. It’s rules-based and transparent, which is why a lot of long-term investors like it.
The Numbers That Matter: Costs and Scale
One of the first things I check with any ETF is the expense ratio. Avantis keeps them genuinely competitive. The average across their lineup is about 0.24 percent, with many core funds at 0.15 percent to 0.25 percent. That’s active-strategy pricing without the usual active-strategy markup.
Take AVUS, their U.S. Equity ETF. Net expense ratio of 0.15 percent. It covers the whole U.S. market but gives a gentle boost to smaller names and higher-profitability companies. Or AVUV, the U.S. Small Cap Value ETF, at 0.25 percent. As of late May 2026 that one alone had roughly $27 billion in assets and had delivered strong year-to-date returns through April—around 18 percent on a market-price basis. International options like AVDE (developed markets) and AVEM (emerging markets) sit in the low-to-mid 0.20s to 0.33 percent range and give you factor exposure that’s hard to find elsewhere at these prices.
The low costs matter because every basis point you save compounds over decades. And because they’re ETFs, you also get tax efficiency and easy trading.
Performance Reality Check
Since most of these funds started in 2019 or shortly after, the live track record is still relatively short. That said, the early results line up with what the research predicts. AVUS has stayed competitive with broad U.S. indexes while adding the tilts. AVUV has shown it can pull ahead meaningfully in periods when small-cap value does well—which it has done historically over long stretches, even if it lags during growth-dominated runs.
International versions have helped fill gaps when U.S. large-cap growth was running hot. The point isn’t that every year will be a winner. Factor premiums show up over full market cycles, not quarters. There will be stretches where these funds trail plain indexes. That’s expected. The design is meant to capture more of the long-term equity risk premium plus the documented size, value, and profitability premiums—without forcing you to pick individual stocks or pay high fees.
Fitting Avantis ETFs Into a Simple Portfolio
I’ve been helping clients build diversified portfolios for years, and the beauty of Avantis is how cleanly they slot in. A core holding like AVUS can serve as your U.S. equity foundation with a built-in tilt. Add a slice of AVUV if you want more small-cap value exposure. Pair them with AVDE or AVDV on the international side and you’ve got a globally diversified equity sleeve that’s still simple to manage.
Newer options like the Total Equity Markets ETF (AVTM, launched early 2026) even let you get broad global exposure in one fund with the same systematic approach. Rebalance once a year, maybe tax-loss harvest when opportunities arise, and then leave it alone. That’s the kind of setup that actually works for real people with real lives.
The thing is, none of this is about chasing the hot fund of the month. It’s about owning a piece of the market in a way that’s backed by decades of data, executed at very low cost, and designed to reward patience. Value and small-cap premiums don’t appear every year, but they’ve shown up reliably enough over long periods that ignoring them entirely feels like leaving return on the table—especially when the cost to access them is this reasonable.
The Bottom Line for Patient Investors
Avantis ETFs aren’t perfect. They’re newer than some legacy providers, and like any factor-tilted strategy they’ll have periods of underperformance. But the combination of experienced team, transparent process, rock-bottom fees, and strong asset growth tells me the market is voting with its dollars for a reason.
If you’re the kind of investor who believes in staying the course through market cycles, these funds give you a practical way to own more of the parts of the market that have historically compensated investors for bearing extra risk. They fit right into a long-term, diversified ETF portfolio without adding complexity or cost.
Time in the market beats timing the market. Avantis just gives that time a little more thoughtful structure.
