Suppose that there are two independent economic factors, F1 and F2. The risk-free rate is 9%, and all stocks have independent firm-specific components with a standard deviation of 49%. The following are well-diversified portfolios: Portfolio Beta on F1 Beta on F2 Expected Return A 2.4 2.6 27% B 3.0 0.26 22% What is the expected returnbeta relationship in this economy? E(rP) = 9 % + (P1 ? %) + (P2 ? %)
