Sharpe Ratio

The Sharpe ratio helps investors understand how much return they're getting for the level of risk taken. A higher Sharpe ratio indicates better risk-adjusted performance, meaning more reward for each unit of risk.

1 Sharpe ratios as of Apr 3, 2026 (values are recalculated daily):

  • 1-Year: 0.21
  • 5-Year: 1.13
  • 10-Year: 1.04
  • All Time: 0.74

These values reflect how efficiently the investment has delivered returns relative to its volatility over different time periods. All figures are annualized and based on daily total returns (including price changes and dividends).

Compared to the broad market, where average Sharpe ratios range from 0.98 to 1.66, this portfolio's current Sharpe ratio places it in the bottom 25%. This suggests weaker risk-adjusted returns than most portfolios, possibly due to lower returns, higher volatility, or both. It may be worth reviewing the allocation. You can use the Portfolio Optimization tool to explore options for improving the Sharpe ratio.

The chart below shows the rolling Sharpe ratio of 1 compared to the selected benchmark. This view highlights how the investment's risk-adjusted performance has changed over time.
