Sharpe Ratio is a measure of historical risk-adjusted performance. It is calculated by dividing the fund's excess returns (the fund's average annual return for the period minus the 3-month "risk free" return rate) and dividing it by the standard deviation of the fund's returns. The higher the ratio, the better the fund's return per unit of risk. The three month "risk free" rate used is the 90-day Treasury Bill rate.
