coefficient of 1.3, and a 20% standard deviation. The risk-free rate is 6%, and the market risk premlum is 5%. a. Calculate each stock's coefficient of variation. Do not round intermediate calculations. Round your answers to two decimal places. CVx=CVy= b. Which stock is riskier for a diversified Investor? 1. For diversified investors the relevant risk is measured by beta. Therefore, the stock with the higher beta is riskler. Stock Y has the higher beta so it is riskier than Stock X. II. For diversified investors the relevant risk is measured by standard deviation of expected returns. Therefore, the stock with the higher standard deviation of expected returns is riskler. Stock X has the higher standard deviation so it is riskier than Stock Y. III. For diversifled investors the relevant risk is measured by beta. Therefore, the stock with the lower beta is riskier. Stock X has the lower beta so it is riskier than Stock Y. IV. For diversified investors the relevant risk is measured by standard deviation of expected returns. Therefore, the stock with the lower standard deviation of expected returns is riskler. Stock Y has the lower standard deviation so it is riskier than Stock X, V. For diversified investors the relevant risk is measured by beta. Therefore, the stock with the higher beta is less risky. Stock Y has the higher beta so it is less risky than Stock X. c.
