{draw:frame} Sharpe Ratio = Where rp = Expected portfolio rate of return rf = Risk free rate of return σp = Portfolio standard deviation Since standard deviation is a measure of the associated risk (systematic + unsystematic) of a portfolio‚ it helps to evaluate whether the portfolio’s returns are due to smart investment decisions or a result of excess risk.
