Formula

Sharpe Ratio Formula
  • Sharpe Ratio = (Expected Return - Risk-Free Rate) ÷ Standard Deviation
  • Expected Return (Rp): Average return of the investment or portfolio
  • Risk-Free Rate (Rf): Return of a risk-free investment (e.g., government bonds)
  • Standard Deviation (σ): Measure of investment volatility or risk

How to Interpret Sharpe Ratio

The Sharpe ratio indicates how much excess return you receive for the extra volatility you endure.

• Sharpe Ratio > 1.0: Good risk-adjusted returns
• Sharpe Ratio 0.5 - 1.0: Acceptable performance
• Sharpe Ratio < 0.5: Poor risk-adjusted returns
• Sharpe Ratio < 0: Returns worse than risk-free rate

Higher Sharpe ratios indicate better risk-adjusted performance. Compare ratios across similar investments to identify the most efficient portfolio.

Important Notes

  • Annualized Figures: Use annualized expected returns, risk-free rates, and standard deviations for accurate comparisons.
  • Risk-Free Rate: Typically use 3-month or 10-year government bond yields as the risk-free rate benchmark.
  • Standard Deviation: Represents total risk (both systematic and unsystematic) of the investment.
  • Limitations: Sharpe ratio assumes normal distribution of returns and doesn't account for skewness or kurtosis.
  • Comparability: Best used to compare investments with similar risk profiles and time horizons.
