问题如下:
In a perfect capital market, all stocks have the same risk premium. Is this statement consistent with CAPM? Explain
解释:
No, the risk premiums for different stocks will not be the same. It is, according to the CAPM:
where cov(Ri, RM) is the covariance between the returns of asset i and the returns of the market portfolio M.
中文解析:该观点与CAPM不符。按照CAPM,股票的风险溢价=(E(RM) - r)* Cov(Ri, RM) / σM2. 不同股票的风险溢价是不一样的。
完美资本市场风险溢价=Rm-Rf吗
