## Did DFAS beat the S&P 500?

Over the 5 years to Oct 30, 2026, Dimensional U.S. Small Cap ETF (DFAS) returned **+42.3%** including dividends, versus **+75.9%** for the S&P 500 (SPY). It lagged the index by 33.6 percentage points, or +7.3% a year against +12.0%.

| Period | DFAS | S&P 500 | DFAS per year | S&P 500 per year | Result |
| --- | --- | --- | --- | --- | --- |
| 1 year | +18.5% | +12.0% | +18.5% | +12.0% | Beat |
| 3 years | +65.8% | +87.4% | +18.4% | +23.3% | Lagged |
| 5 years | +42.3% | +75.9% | +7.3% | +12.0% | Lagged |

Total return with dividends reinvested, from month-end prices to Oct 30, 2026. Beating the index on raw return is only half the story: the next section adjusts for the risk taken. See also [how to beat the S&P 500](https://www.exent.ai/beat-the-market).

## Is DFAS good for retirement?

**DFAS can be a core retirement holding. It is Dimensional’s active, systematic US small-cap fund.** A broad small-cap fund (about 2,000 stocks) with tilts away from expensive, unprofitable and recently weak stocks; a small-cap sleeve, not a whole portfolio.

#### Pros

- Converted from a tax-managed mutual fund in 2021 and managed to limit realized gains (Dimensional).

#### Cons

- 0.31% versus 0.03% for VB; the tilt has to earn its fee.
- Small caps as a group lagged large caps over the last five years.

**When it is the wrong choice:** If you cannot explain why you pay ten times the index fee: the case rests on factor research you should be comfortable with.

## DFAS returns by year vs the S&P 500

DFAS beat the S&P 500 in 1 of the 4 full calendar years shown.

| Year | DFAS | S&P 500 | Difference |
| --- | --- | --- | --- |
| 2026 (to Oct 30, 2026) | +15.1% | +11.7% | +3.4% |
| 2025 | +8.2% | +17.7% | −9.5% |

| 2023 | +17.8% | +26.2% | −8.4% |
| 2022 | −13.8% | −18.2% | +4.4% |

## DFAS risk-adjusted returns: Sharpe, Sortino and volatility

Over 5 years, DFAS had a Sharpe ratio of **0.27** against 0.58 for the S&P 500, so it earned less return per unit of risk than the index. Its annualized volatility was 19.4% and its beta 1.03: it tended to move about 1.0× as much as the market.

| Metric | DFAS | S&P 500 |
| --- | --- | --- |
| Annual return | +7.3% | +12.0% |
| Volatility (annualized) | 19.4% | 15.5% |
| Sharpe ratio | 0.27 | 0.58 |
| Sortino ratio | 0.43 | 0.91 |
| Max drawdown (month-end) | −21.9% | −23.9% |
| Beta to the S&P 500 | 1.03 | 1.00 |

[Sharpe](https://www.exent.ai/learn/sharpe-ratio) divides return above cash by total volatility; [Sortino](https://www.exent.ai/learn/sortino-ratio) counts only downside volatility. Both use monthly returns and the 1–3 month T‑bill ETF (BIL) as the risk‑free rate.

## How DFAS behaved in past crashes

DFAS’s deepest fall in the crises below was **−23.6%** in the 2022 inflation bear market, against −25.4% for the S&P 500. The last column turns that into money: what a $100,000 position would have lost from peak to trough.

| Crisis | DFAS | S&P 500 | Loss on $100,000 |
| --- | --- | --- | --- |
| 2022 inflation bear market | −23.6% | −25.4% | −$23,590 |
| 2025 tariff selloff | −21.8% | −19.0% | −$21,820 |

| Window | DFAS max drawdown |
| --- | --- |
| Last 1 year | −9.4% |
| Last 3 years | −26.1% |
| Last 5 years | −26.1% |
| Last 10 years | −27.3% |

Peak‑to‑trough declines from daily prices inside each crisis window. A crash replay does not predict the next crisis; it shows how much room a holding needs. Run the same replay on a whole portfolio with the [crash test](https://www.exent.ai/tools/crash-test).

## What moves with DFAS, and what doesn’t

Correlation runs from −1 (moves opposite) to +1 (moves in lockstep). Over the last 60 months of monthly returns, DFAS’s correlation with the S&P 500 was **0.82**, with the Nasdaq‑100 0.64, with long Treasuries (TLT) 0.53 and with gold (GLD) 0.10.

## The right benchmark for DFAS

Exent matches every holding to the index with the most similar risk. For DFAS that is **MDY**. Comparing a holding with an index that carries very different risk makes good results look bad and risky ones look clever.
