这题具体是考察哪个知识点?

NO.PZ2022081802000060

问题如下:

Question Stock X and Stock Y have the same level of total risk. Stock X has twice the systematic risk of Stock Y and half its non-systematic risk. Stock X’s expected return will most likely be:

选项:

A.the same as the expected return of Stock Y. B.lower than the expected return of Stock Y. C.higher than the expected return of Stock Y.

解释:

Solution

C is correct. Because Stock X has a higher systematic risk level compared with Stock Y, its expected return will be higher than that of Stock Y.

A is incorrect because Stock X has a higher systematic risk level compared to Stock Y, implying a higher (not the same) expected return compared to Stock Y.

B is incorrect because Stock X has a higher systematic risk level compared to Stock Y, implying a higher (not lower) expected return compared to Stock Y.

嗨,爱思考的PZer你好:


我们CAPM定价模型有一个前提假设就是资产或者组合都是well-diversified的。系统性风险是不能够被分散掉的,所以必须要给予相应的风险补偿。而非系统性风险是能够通过组合分散掉的,所以并不需要对非系统性风险提供风险补偿。所以系统性风险越大的,expected return就会越大。
