D选项怎么用CAPM去定预期价格啊?A选项1.any security,又没说一定要在SML线上啊。2、market price of risk和组合risk这两个点怎么理解啊,risk in the portfolio就能是系统性风险咯?

CAPM计算出来的收益率可以给股票进行定价,如优先股定价:P=c/re(了解即可)
The security market line (SML) states that the expected return on any security is
the riskless rate of interest plus the market price of risk times the amount of risk
in the security or portfolio.
这句话就是在描述CAPM公式本身,这句话意思是:证券市场线(SML)规定,任何证券的预期回报率是无风险利率加上风险的市场价格乘以证券或投资组合中的风险量。r=rf+β(rm-rf)
