Davis Government Bond Fund (RFBAX) Sharpe Ratio: 1.76

Mutual Fund · Currency in USD · Last updated Jul 11, 2026

The investment seeks current income. The fund invests exclusively in U.S. Treasury securities, U.S. government agency securities, U.S. government agency mortgage securities (collectively "U.S. government securities"), and repurchase agreements collateralized by U.S. government securities. Under normal circumstances, the fund's portfolio will maintain a weighted average maturity of three years or less.

RFBAX's Sharpe Ratio of 1.76 indicates that for each unit of volatility, it generates 1.76 units of excess return above the risk-free rate. The ratio is calculated using historical daily returns over the past 12 months (as of Jul 11, 2026).

Sharpe uses total volatility (standard deviation) which includes both upside and downside price movements, making it useful for comparing risk-adjusted returns across different assets. For how to read this number and when it can mislead, see Sharpe Ratio Explained.
