ToggleWhat Are DFA Funds?
Dimensional Fund Advisors (DFA) offer investment funds designed to capture dimensions of market returns based on decades of academic research. Established in 1981, DFA Funds use a disciplined, evidence-based approach to investing. They focus on targeting factors that historically improve long-term returns, such as small market capitalization, value, and profitability.
DFA Funds employ an active indexing strategy, which sets them apart from traditional index funds. Instead of merely mimicking a market index, DFA Funds tilt portfolios toward specific factors, such as profitable companies with smaller market caps and away from expensive stocks. This enhanced strategy aims to add value while maintaining low costs and high tax efficiency.
Key Features of DFA Funds
1. Active Indexing Strategy
DFA Funds combine the efficiency of index investing with active adjustments to tilt portfolios toward dimensions that improve returns, such as size, value, and profitability. This unique approach helps DFA Funds outperform in the long term.
2. Factor Tilts
DFA Funds overweigh small-cap stocks, value stocks, and profitable companies while underweighing expensive companies. Research has shown these factors contribute significantly to long-term portfolio growth.
3. Exclusive Access
DFA ETFs are accessible to all investors, while DFA mutual funds are offered solely through financial advisors. This exclusivity ensures that investors benefit from expert guidance in structuring their portfolios to meet long-term financial objectives.
Why may DFA funds be superior?
DFA Funds are often considered superior due to their unique blend of active indexing, cost efficiency, and disciplined investment approach. Here are the key reasons why DFA Funds may be superior:
1. Active Indexing for Added Value
DFA Funds enhance returns by adjusting their portfolios to favor specific factors. This strategy allows DFA to outperform traditional index funds, which strictly replicate a market index.
2. Focus on Factors That Drive Returns
DFA tilts portfolios toward companies demonstrating profitability, smaller market capitalizations, and lower valuations. Studies show these three factors consistently improve long-term returns, making DFA Funds particularly effective in uncertain economic environments.
3. Strong Historical Performance
With more than 80% of DFA Funds beating their benchmarks over the past two decades, their performance track record is one of the strongest in the industry. This success underscores the effectiveness of their investment philosophy. For example, the DFA US Small Cap Portfolio (DFAS) has outperformed its benchmark at the 3-year, 5-year, and 10-year marks, showcasing the consistency and reliability of DFA’s factor-based strategies.
4. Tailored Exposure for Long-Term Gains
Given the uncertain economic landscape, there is an increased focus on DFA ETFs and an emphasis on U.S. small-cap stocks, which have historically delivered stronger long-term performance compared to U.S. large-cap stocks. This strategic approach aims to enhance growth potential within portfolios.
5. Lower-Cost Compared to Traditional Active Funds
DFA blends the cost-efficiency of passive investing with a carefully structured, rules-based approach. Unlike traditional active funds, which rely on expensive stock picking and frequent trading by portfolio managers, DFA Funds use an evidence-based methodology to target specific return dimensions. This reduces the need for high management fees while minimizing trading costs associated with excessive portfolio turnover.
Additionally, DFA’s systematic strategy avoids the overhead of maintaining large research teams or pursuing speculative market timing, further keeping expenses in check. As a result, investors benefit from a cost-effective solution that delivers enhanced returns through strategic portfolio tilts.
DFA Funds Performance: How Do They Compare?
DFA Funds have consistently demonstrated strong performance by leveraging their factor-tilted strategies and active indexing. Here’s how DFA compares to traditional index funds and other investment options:
DFA Funds vs. Index Funds
Traditional index funds passively track market benchmarks, offering low-cost exposure to broad markets. In contrast, DFA Funds actively adjust their portfolios to target specific factors. This approach has led to superior long-term performance, particularly in markets where factor-driven strategies excel.
DFA Funds vs. Vanguard
Vanguard is known for its ultra-low-cost index funds. While Vanguard funds provide excellent broad-market exposure, they lack the strategic tilts and active indexing employed by DFA Funds. The result? DFA Funds can potentially deliver higher returns in the long run, especially for investors seeking to capitalize on dimensions of return such as size and value.
Advantages of DFA Funds
The advantages of DFA Funds stem from their research-driven approach and long-term focus. Here’s what sets them apart:
1. Enhanced Diversification
DFA funds provide broader market exposure than traditional index funds by tilting portfolios toward small-cap and value stocks. This diversification reduces risk while maximizing potential returns.
2. Factor-Based Strategy
DFA Funds prioritize factors proven to improve returns, such as high profitability and small market capitalization while reducing exposure to overvalued stocks.
3. Tax Efficiency
DFA Funds employ tax-efficient trading strategies, making them an excellent option for taxable accounts.
4. Professional Guidance
Since some DFA Funds are only available through approved financial advisors, investors benefit from expert advice on portfolio construction, rebalancing, and long-term planning.
Disadvantages of DFA Funds
1. Limited Accessibility
Some DFA Mutual Funds are only available through approved financial advisors, which can restrict access for individual investors who prefer to manage their portfolios. This does not apply to ETFs, which are available to all investors.
2. Higher Costs Compared to Index Funds
While less expensive than other actively managed funds, DFA Funds often have higher expense ratios than traditional index funds, which may be a drawback for cost-sensitive investors.
3. Dependence on Market Conditions
DFA’s factor-based strategies may underperform during certain market conditions, particularly when small-cap or value stocks are out of favor.
4. Potential for Short-Term Underperformance
DFA Funds’ long-term approach can sometimes result in short-term performance lagging behind traditional benchmarks or more aggressive strategies.
DFA ETFs vs DFA mutual funds
DFA offers ETFs and mutual funds, each designed to reflect its evidence-based investment approach rooted in academic research. The primary distinction between DFA ETFs and DFA mutual funds lies in their structure and accessibility.
DFA ETFs are traded on stock exchanges, offering intraday liquidity and typically lower expense ratios than their mutual fund counterparts. This makes them an attractive option for cost-conscious investors seeking flexibility. On the other hand, DFA mutual funds often require working with approved financial advisors, ensuring professional guidance in aligning investments with long-term financial goals.
While both options adhere to DFA’s systematic strategies, the choice depends on the investor’s preference for hands-on trading or advisory-led financial planning.
Where To Buy DFA Funds
DFA ETFs can be purchased through major brokerage platforms, including popular online brokers like Charles Schwab, Fidelity, TD Ameritrade, and E*TRADE. Since DFA ETFs trade on stock exchanges, they are accessible to any investor with a brokerage account, offering the flexibility to buy and sell throughout the trading day. Be sure to compare brokerage fees and features to find the best platform for your investment needs.
DFA mutual funds aren’t available directly to retail investors. You must work with an authorized financial advisor to access these funds. This ensures that your investments are managed strategically and align with your financial goals.

Can DFAs Outperform the Market?
While extensive academic research sheds light on what drives investment returns, past performance does not guarantee future results. Expected returns are influenced by current market prices and anticipated future cash flows. Dimensional’s investment strategies are rooted in rigorous research, leveraging insights to focus on areas of the market that historically offer higher expected returns based on current valuations.
Investors can use these insights to target premiums and aim for higher returns relative to the broader market. The key drivers of higher expected returns are grouped into three dimensions: Size (small-cap vs. large-cap stocks), Relative Price (value stocks vs. growth stocks), and Profitability (high-profitability vs. low-profitability stocks).
As shown in the historical data across various markets—whether U.S., developed international, or emerging markets—the small-cap, value, and high-profitability factors consistently demonstrate premiums over time. By strategically tilting portfolios toward stocks exhibiting these traits, investors can position themselves to potentially outperform the market, though it’s important to note that outperformance can never be guaranteed.
Do You Want To Add DFA Funds To Your Portfolio?

Frequently Asked Questions
1. What makes DFA Funds different from traditional index funds?
DFA Funds use an “active indexing” approach. Instead of passively replicating an index, they tilt portfolios toward factors such as small-cap, value, and profitable companies. This disciplined, research-based strategy aims to capture dimensions of expected returns while keeping costs relatively low.
2. Can anyone invest in DFA Funds?
DFA Exchange-Traded Funds (ETFs) are available to all investors through major brokerages. DFA mutual funds, however, are only accessible through financial advisors approved by Dimensional Fund Advisors. This structure ensures investors using DFA mutual funds also receive professional portfolio guidance.
3. Do DFA Funds always outperform the market?
No investment strategy can guarantee outperformance. While DFA’s factor-based approach has delivered strong historical results, performance depends on market conditions. For example, DFA’s emphasis on value and small-cap stocks may lag during periods when growth or large-cap stocks dominate.
4. Are DFA Funds more expensive than index funds?
Yes, in most cases. DFA Funds typically carry higher expense ratios than ultra-low-cost index funds like those offered by Vanguard. However, DFA’s costs are generally lower than many traditional actively managed funds, and investors weigh the added value of DFA’s evidence-based strategy against slightly higher fees.
5. Are DFA Funds suitable for long-term investors?
DFA’s philosophy is designed for long-term portfolios. The funds emphasize diversification, disciplined trading, and factors that have historically generated higher expected returns over decades. While they can experience short-term underperformance, their structure is meant to align with long-term financial planning goals.
