请教下老师,这道题答案是不是有问题??为什么不是 3%+1.5*(6%-3%)
NO.PZ2015121801000102 问题如下 analyst gathers the following information:With respeto the capitasset pricing mol, if the expectemarket risk premium is 6% anthe risk-free rate is 3%, the expectereturn for Security 1 is closest to: A.9.0%. B.12.0%. C.13.5%. is correct.The expectereturn of Security 1, using the CAPM, is 12.0% = 3% + 1.5(6%); E(Ri) = Rf + βi[E(Rm)–Rf]. 为什么不是a呢。。
ERm-Rf应该是0.06-0.03=0.03啊
