Understanding the Sharpe Ratio

Formula

Sharpe Ratio = (Portfolio Return - Risk-Free Rate) / Standard Deviation

Key Components

Portfolio Return

The expected or historical return of your investment portfolio over a specific period.

Risk-Free Rate

The return of a risk-free investment, typically government treasury bonds.

Standard Deviation

A measure of the portfolio's volatility or risk, showing how much returns vary.

Practical Applications

  • Compare different investment strategies on a risk-adjusted basis
  • Evaluate mutual fund or portfolio manager performance
  • Determine if additional risk is being adequately compensated
  • Make informed decisions about portfolio allocation
  • Screen investments for optimal risk-return profiles

Limitations

  • Assumes returns are normally distributed
  • Only considers downside and upside volatility equally
  • Based on historical data which may not predict future performance
  • Doesn't account for skewness or kurtosis in return distributions
  • May not be suitable for strategies with asymmetric risk profiles
