ch Ch 08-End-of-Chapter Problems - Risk and Rates of Return Part I-GRADED Stocks A and B have the following probability distributions of expected future returns: Probability 0.1 0.2 0.5 0.1 0.1 A (8%) 6 11 24 39 a. Calculate the expected rate of return, F, for Stock B (FA- 12.20%.) Do not round intermediate calculations. Round your answer to two decimal places. % B (32%) 0 b. Calculate the standard deviation of expected returns, d, for Stock A (os - 20.78%.) Do not round intermediate calculations. Round your answer to two decimal places. Now calculate the coefficient of variation for Stock B. Do not round intermediate calculations. Round your answer to two decimal places. 23 26 50 Is it possible that most investors might regard Stock B as being less risky than Stock A? 1. If Stock B is more highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be less risky in a portfolio sense. OE II. If Stock 8 is more highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. #T III. If Stock 8 is more highly correlated with the market than A, then it might have the same beta as Stock A, and hence be just as risky in a portfolio 4 sense. IV. If Stock B is less highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. V. If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense. a U 58F X 9:28 PM 6/21/200 MEKANIZEM V. Istock B IS less rigny correlated with the marker than A, then it mignit nave a nigner beta than stock A, and nence ne more nsky in a portrono sense, -fielect v c. Assume the risk-free rate is 1.5%. What are the Sharpe ratios for Stocks A and 87 Do not round intermediate calculations. Round your answers to four decimal places. Stock A: Stock B: Are these calculations consistent with the information obtained from the coefficient of variation calculations in Part b? I. In a stand-alone risk sense A is more risky than B. If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense. II. In a stand-alone risk sense A is less risky than B. If Stock B is more highly correlated with the market than A, then it might have the same beta as Stock A, and hence be just as risky in a portfolio sense. III. In a stand-alone risk sense A is less risky than B. If Stock B is less highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. IV. In a stand-alone risk sense A is less risky than 8. If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense. V. In a stand-alone risk sense A is more risky than B. If Stock B is less highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. -Select- he Grade it Now Save & Continue Continue without saving
