The historical sharpe ratio uses historical returns to calculate the return and standard deviation. On top of that, the Geometric Sharpe Ratio takes actual returns into account and is a more conservative ratio. It compares a fund's historical or projected returns relative to an investment benchmark with the historical or expected variability of such returns.
