The figure below shows the expected yearly return v.s. the beta of various portfolios in a market in which the assumptions of CAPM hold. We also know that the mean and standard deviation of the yearly returns of the market portfolio are 20% and 8%, respectively. Find equations for the capital market line (CML) and the CAPM formula, make sure to include explicit values for the coefficients. Explain how you derive the equations. A portfolio has a standard deviation of 10% and a correlation coefficient of 0.5 with the market. What is the initial value of this portfolio if its expected value after one year is $1,000,000? Explain your answer What is the correlation coefficient of an efficient portfolio with the market portfolio? You must prove your answer for any efficient portfolio
