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 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.

MetricDFASS&P 500
Annual return+7.3%+12.0%
Volatility (annualized)19.4%15.5%
Sharpe ratio0.270.58
Sortino ratio0.430.91
Max drawdown (month-end)−21.9%−23.9%
Beta to the S&P 5001.031.00

Sharpe divides return above cash by total volatility; Sortino 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.

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. Read why the S&P 500 is the wrong benchmark for most portfolios.
