⚖️ Risk-Adjusted Performance
Sharpe and Sortino ratios from a return series.
What it does
Computes average return, volatility, and the Sharpe and Sortino ratios from a series of periodic returns, so you can judge risk-adjusted performance.
When to use it
Use it to compare two funds or strategies on an equal footing — higher return is only 'better' if it isn't bought with disproportionate risk.
Assumptions
- Returns are entered as percentages per period (monthly or annual).
- Sharpe uses total volatility; Sortino uses only downside volatility.
- More periods give a more reliable estimate.
Inputs
Pro tip
Prefer the fund with the better Sharpe/Sortino over the one with the higher raw return when you will hold through volatility. A Sharpe above 1 is good and above 2 is strong. Sortino is the better gauge for strategies that aim to cut downside.
