Suppose that the index model for stocks A and B is estimated from excess returns with the following results: R_A = 5.0% + 1.30R_M + e_A R_B = 2.0% + 1.60R_M + e_{B M} = 20%; R-square_A = 0.20; R-square_B = 0.12 Assume you create a portfolio Q, with investment proportions of 0.40 in a risky portfolio P, 0.35 in the market index, and 0.25 in T-bill. Portfolio P is composed of 70% Stock A and 30% Stock B.
