4 ETFs That Beat the S&P 500 by Ignoring Market Cap Entirely

Quick Read

• Invesco RAFI US 1000 ETF (PRF) weights 1,000 large US companies by fundamental metrics like sales and cash flow rather than market cap, holding $9B in assets with an 18% trailing twelve-month return and 0.34% expense ratio. Schwab Fundamental U.S. Small Company ETF (FNDA) applies the same RAFI methodology to small caps with lower expenses at 0.25%, returned 16.6% over the past year, and holds 500-plus positions with no single holding exceeding 1.06% of assets. Dimensional U.S. Targeted Value ETF (DFAT) screens for small and mid-cap stocks across size, value, and profitability simultaneously, manages $13.2B with a 0.28% expense ratio, returned 19% trailing twelve months, and concentrates 28% in financials to filter out value traps.

• Fundamental indexing and factor-based approaches address the structural flaw in market-cap weighting by anchoring portfolios to business economics rather than price momentum, with international and small-cap versions of these strategies capturing distinct market inefficiencies.

Market-cap weighting has a structural flaw that most investors overlook: it automatically overweights whatever has already gotten expensive. The four ETFs below take a different approach, using fundamental data and systematic factor tilts to build portfolios that are less beholden to price momentum and more anchored to economic reality. Two follow the Research Affiliates Fundamental Index (RAFI) methodology. Two come from Dimensional Fund Advisors. Together they cover US large-cap, US small-cap, US targeted value, and international value — four distinct angles on the same core idea.

RAFI Methodology: What It Actually Does

The RAFI approach weights companies by measures of economic footprint — sales, cash flow, dividends, and book value. These replace stock price multiplied by shares outstanding. The result is a portfolio that naturally tilts toward cheaper stocks, since a company trading at a low multiple relative to its fundamentals will receive more weight than its market cap alone would suggest. This creates a built-in value tilt without explicitly screening for value stocks.

PRF: Large-Cap Fundamentals with a Long Track Record

Invesco RAFI US 1000 ETF (NYSEARCA:PRF) applies the RAFI methodology to roughly 1,000 large US companies, making it the most straightforward entry point into fundamental indexing for investors who want large-cap exposure without abandoning familiar names entirely.

Have You read The New Report Shaking Up Retirement Plans? Americans are answering three questions and many are realizing they can retire earlier than expected.

The portfolio still holds recognizable giants — Alphabet, Apple, and Microsoft sit among the top positions — but their weights reflect revenue and cash flow scale rather than market enthusiasm. Financials represent 16.3% of the fund, meaningfully above their weight in a typical S&P 500 fund, while the largest tech names are trimmed relative to a cap-weighted index. Information Technology still accounts for 18.2% of the portfolio, so this is not an anti-tech fund — it just sizes tech positions by business fundamentals rather than valuation multiples.

PRF carries an expense ratio of 0.34% and has been running since December 2005, giving it nearly two decades of live performance history. Assets under management stand at $9 billion. The fund returned 18% over the trailing twelve months and is up 1.5% year-to-date. The tradeoff: in momentum-driven markets where the most expensive stocks keep climbing, PRF’s value tilt can lag a standard S&P 500 index fund for extended periods.

FNDA: The Same Philosophy, Applied to Small Caps

Schwab Fundamental U.S. Small Company ETF (NYSEARCA:FNDA) uses the identical RAFI weighting system as PRF but applies it to the small-cap universe. This matters because the fundamental weighting effect tends to be more pronounced in smaller companies, where the gap between market price and underlying business value is often wider.

The sector mix reflects this: Industrials dominate at 20.4%, followed by Financials at 15.2% and Consumer Discretionary at 12.5%. Technology takes a back seat at 13.2%. The top holding represents just 1.06% of assets, meaning no single bet dominates the portfolio. With 500-plus positions, diversification is genuine rather than cosmetic.

Cost is a clear advantage here. The expense ratio is 0.25%, lower than PRF, which matters when comparing two funds built on the same methodology. FNDA returned 16.6% over the past year and is up 3.5% year-to-date. The caveat specific to small caps: this segment of the market is more sensitive to economic slowdowns and credit conditions, so FNDA will feel more turbulence than PRF during risk-off periods.

DFAT: Dimensional’s Targeted Value Approach

Dimensional U.S. Targeted Value ETF (NYSEARCA:DFAT) diverges from the RAFI funds in a meaningful way. Rather than reweighting an existing index by fundamental metrics, Dimensional constructs its portfolio by actively targeting small and mid-cap stocks that score well on three factors simultaneously: small size, deep value, and profitability. That last screen is critical: it filters out value traps, companies that look cheap because their businesses are deteriorating.

The sector composition tells the story clearly. Financials represent nearly 28% of the portfolio, the highest concentration of any fund on this list, followed by Industrials at 16.2% and Consumer Discretionary at 14.2%. Regional banks, specialty insurers, and asset managers fill the financial sleeve. Technology is intentionally underweighted at 6.9%, reflecting the reality that most tech companies do not score well on traditional value metrics.

DFAT holds $13.2 billion in assets and charges 0.28% annually. Portfolio turnover is exceptionally low at 9%, a sign that Dimensional is not trading aggressively to maintain factor purity — it buys and holds companies that meet its criteria. The fund returned 19% over the trailing twelve months, the strongest one-year number among the four. The tradeoff is concentration: a nearly 28% allocation to financials means DFAT’s performance is meaningfully tied to the health of banks and insurance companies.

DFIV: Dimensional’s Factor Lens Applied Internationally

Dimensional International Value ETF (NYSEARCA:DFIV) applies the same systematic value and profitability screens as DFAT, but to developed international markets. For investors who already hold a US-focused factor fund, this is the natural complement — it extends the same investment logic to European, Asian, and Canadian companies without adding a separate geographic allocation decision.

The holdings read like a directory of globally significant value companies: Shell, TotalEnergies, BP, and Suncor anchor the energy sleeve, while Banco Santander, HSBC, Société Générale, and several Japanese financial institutions populate the financials allocation. The dividend yield stands at 2.6%, the highest of the four funds, reflecting the income-generating character of many international value companies. Portfolio turnover is just 6%, even lower than DFAT, consistent with Dimensional’s patient, systematic approach.

DFIV manages $19 billion in assets and charges 0.27% annually. The one-year return of 32.8% leads the group, driven partly by international equity tailwinds that have benefited non-US markets recently. The tradeoff here is currency exposure and geopolitical sensitivity — European and Asian equities carry risks that domestic funds do not, and the fund’s heavy energy weighting adds commodity price variability on top of that.

Which Fund Fits Which Investor

PRF suits investors who want to stay in familiar US large-cap territory but want the portfolio to reflect business fundamentals rather than market sentiment. FNDA is the better choice for those who want to extend that same logic into small caps at a lower cost. DFAT is the most aggressive factor bet on this list. It concentrates deeply in small and mid-cap value with a profitability filter that separates it from simple value screens, and belongs with investors who understand and accept meaningful sector concentration. DFIV rounds out a factor-tilted portfolio with international exposure and the highest income yield of the group, making it particularly relevant for investors who want geographic diversification without abandoning the value and profitability framework.
