In the article on portfolio theory, we saw that the motivation behind the establishment of a portfolio is that risk (the bad) can be reduced without a consequential reduction in return (the good). This was mathematically evident when the portfolios' expected return was ...
To make effective financial decision, managers need to understand how risk should be measured and the effect of risk on the rate of return required by investors. In this chapter, we will focus our discussion on the risk and return using the framework of portfolio theory, and CAPM which links...
If \operatorname{Prob}\left(\widetilde{R}>R_{f}\right)=0 , for example, the return on the risky asset is always below the risk-free return, so the investor would like to build up an infinitely large negative position in the risky asset. On the other hand, if the first order ...
