问题如下：
An analyst gathers the following information:
With respect to the capital asset pricing model, a decline in the expected market return will have the greatest impact on the expected return of:
选项：
A.Security 1.
B.Security 2.
C.Security 3.
解释：
C is correct.
Security 3 has the highest beta; thus, regardless of the risk-free rate the expected return of Security 3 will be most sensitive to a change in the expected market return.
E(r)=risk-free rate + B(RM-RF)
我当时的理解是 每个资产的RF都一样 β越大的算出的结果越大
老师请问 我这个想法错在哪里
