How this Sharpe Ratio Calculator works
The Sharpe ratio divides excess return by standard deviation. When periodic inputs are selected, average return and risk-free return are multiplied by periods per year while volatility is multiplied by the square root of periods.
Important: Historical Sharpe ratios do not predict future performance and can be misleading for non-normal, illiquid or option-like returns. This is not investment advice.
What assumptions should I verify?
