Beta as a measure of risk:
Jensen’s alpha = return - CAPM expected return
Treynors measure = (expected return - RF)/Beta, which is the slope of the line plotted on the graph (return/beta)
Total risk as the measure
Sharpe Ratio = (expected return - RF)/Total Risk, the slope of the line plotted on the graph (return/total risk)
M2 = the theoratical return if the portolio had the same risk as the market - RF + (portfolio return - RF)*market risk/portolio risk
Active risk as the measure
Information Ratio = active return per unit of active risk
