对答案有点疑问

NO.PZ2018070201000104

问题如下:

Based on the capital asset pricing model, please choose the security that has the highest expected return assuming the expected market risk premium if 8%.

选项:

A.

Security 1.

B.

Security 2.

C.

Security 3.

解释:

C is correct.

E(Ri) = Rf + βi[E(Rm)–Rf]

Security 3 will have the highest expected return among all three securities because it has the highest beta.

1.老师能求下1和2的结果代入分别等于多少吗?

嗨,从没放弃的小努力你好:


这个题不是通过计算判断的。根据CAPM公式E(Ri) = Rf + βi[E(Rm)–Rf],本题中没有给出Rf,所以没有办法算出来具体的数字比较。

Rf都是一样的,[E(Rm)–Rf]给了是8%,所以我们只需要比较β大小就可以了。Security3的beta最大。所以选C

努力的时光都是限量版,加油!
