If the CAPM is correct, then the market portfolio has the highest Sharpe ratio. Since portfolio A has the higher Sharpe ratio, it must be the market portfolio. 11. The CAPM implies E(RA ) − RF = β A (E(RM ) − RF ) . E ( R A ) − RF .10 − .02 Cov ( R A , RM ) Therefore, β A = , we have = = 2 . Since β A = E ( RM ) − RF .06 − .02 Var ( RM ) Cov ( RA , RM ) = β AVar( RM ) = 2 × (.03) 2 = 0.0018 . E ( R X ) − RF 0.13 − 0.05 12. The Sharpe ratio of Fund X is = = 0.53 while that for Fund Y σX 0.15 E ( RY ) − RF 0.12 − 0.05 is = = 0.23 . Therefore, Fund X is better on the...
