Suppose there is a financial market with only one risk-free asset (return of 3%) and many risky assets. There is a stock X that delivers a return of 13% with st. dev. of 40%. The market portfolio of all traded risky assets has st. dev. of 10%. The correlation coefficient between stock X and the market portfolio is 0:5. What is the beta of stock X, with respect to the given market portfolio? Additionally, if the CAPM assumptions hold, what is the expected rate of return of the market portfolio?
