问题如下:
The rate of return on stock A and stock B will be the same each month if they have the same beta.
选项:
A.
True
B.
False
解释:
False
The realized return is random. CAPM predicts that the expected rates of return for stocks A and B should be the same.
中文解析:
股票的实际收益率是随机的,无法预测的。CAPM只能判断股票的预期收益率。如果A和B的β相等,那么根据CAPM,二者的预期收益率应当相等,但实际收益率是否相等无法判断。
如果这道题说根据CAPM的话,理论上两者的预期收益是相等的对吗?
