Dimensional U.S. Core Equity 2 ETF (DFAC)

The Dimensional U.S. Core Equity 2 ETF (ticker DFAC) holds a broad roster of U.S. stocks but tilts toward value — companies trading at lower multiples of earnings — and profitability. Rather than weight stocks by market cap like the S&P 500, Dimensional screens for value and financial strength, meaning cheaper, better-managed firms anchor the portfolio more heavily than the market’s size-based sorting would place them. It is a U.S. equity fund built on the academic belief that value and profitability beat over the long run.

What makes DFAC different from the S&P 500?

The S&P 500 (the most popular U.S. equity index) weights stocks by market capitalization — Apple gets a far larger slice because it is worth more than any other company. DFAC uses a different logic: it applies Dimensional’s screening process to identify value and profitable companies across the market and then weights them according to these fundamental characteristics. A bank with solid profits and a low price-to-earnings ratio will carry more weight than a comparably-sized but much-pricier software company. Over decades, the research shows, this tilt toward value and profitability has historically beaten market-cap weighting, though not every year.

How does Dimensional’s screening actually work?

Dimensional does not employ stock pickers making subjective bets on individual companies. Instead, it applies transparent, rules-based filters. The firm screens the broad U.S. stock universe for value (stocks trading at lower prices relative to earnings and book value) and profitability (companies with healthy return on assets and low financial leverage). The fund then constructs a portfolio that emphasizes these characteristics while maintaining broad diversification across sectors and market caps. Quarterly rebalancing ensures that the portfolio stays tilted toward value and profitability rather than drifting as stock prices change.

Is DFAC a cheap alternative to an S&P 500 fund?

Not quite. The expense ratio is low — Dimensional keeps costs lean — but DFAC is not a minimal-cost tracker like a Vanguard or iShares S&P 500 fund, which charge some of the lowest fees in the industry. However, the fee difference is modest, and the historical academic case for value and profitability tilts suggests that DFAC’s screening and weighting may recoup its slightly higher cost through superior returns over full market cycles. That said, over any single year or stretch, the value tilt can underperform. DFAC lagged significantly during the 2010s when expensive tech stocks dominated, for example.

Who is DFAC for?

DFAC appeals to U.S.-equity investors convinced by academic research into factor premiums — the idea that value and profitability drive returns — and willing to tolerate years where their tilted portfolio underperforms the market cap benchmark. It is also useful for investors already holding a broad market-cap fund who want to tilt toward value without selling the core holding and incurring taxes. As a satellite position or a full core U.S. equity holding, DFAC offers a systematic, transparent alternative to both pure market-cap tracking and active stock picking.

What is the catch?

The main risk is factor rotation. When expensive growth stocks outperform (as they did in the 2010s and again in 2023), DFAC will lag. An investor needs a long time horizon — ideally ten years or more — to harvest the value and profitability premiums. Additionally, the fund holds roughly 1,500 U.S. stocks across all market caps, which is far broader than the S&P 500’s 500, so it includes plenty of small-cap and mid-cap names that swing more widely than mega-cap leaders. That breadth is a strength for diversification but means higher volatility. Finally, Dimensional’s rebalancing creates turnover (more buying and selling than a static index fund), which can generate a small tax drag in taxable accounts.

How do you research DFAC before buying?

Read Dimensional’s index methodology on the company’s website to understand exactly how the value and profitability screening works. Check the current top 10 holdings and sector breakdown to see what kind of companies the fund favors — you should see financial, industrial, and energy firms (historically value sectors) more heavily weighted than in the S&P 500. Compare DFAC’s five- and ten-year returns to both an S&P 500 index fund and other value-tilted U.S. equity offerings like Vanguard’s value funds or factor competitors. Watch the current price-to-earnings ratio and price-to-book ratio of DFAC versus the broad market to see how much the value tilt is currently discounting the fund. Finally, confirm the expense ratio and consider the tax implications of owning DFAC in a taxable account versus tax-advantaged retirement accounts, where rebalancing tax drag does not apply.
