Suppose that there are two independent economic factors, F1 and F2. The risk-free rate is 1.0%, and all stocks have independent firm-specific components with a standard deviation of 25%. The following are well-diversified portfolios; e.g., Portfolio (A) has a beta sensitivity to factor the first factor, β(F1), of 1.20 and an expected return of 13.0%:「huixue_img/importSubject/1564170575868465152.png」
Which is the correct return-beta relationship in this economy?
选项
A.E[R(P)] = 1.0% - β(F1)×6.0% - β(F2)×4.0%
B.E[R(P)] = 1.0% - β(F1)×5.0% + β(F2)×2.0%
C.E[R(P)] = 1.0% + β(F1)×9.0% + β(F2)×3.0%
D.E[R(P)] = 1.0% + β(F1)×12.0% + β(F2)×8.0%
答案
D
解析
We need to solve for two equations with two unknowns:「huixue_img/importSubject/1564170575964934144.png」Solving the equations, we will get: RP(1)=0.12 RP(2)=0.08So the answer is: 「huixue_img/importSubject/1564170576048820224.png」
