Problem 8-1 Expected return A stock's returns have the following distribution: Demand for the Probability of This Company's Products Demand Occurring Rate of Return If This Demand Occurs Weak 0.1 -30% Below average 0.1 -15 Average 0.5 15 Above average 0.1 22 Strong 0.2 52 1.0 a. Calculate the stock's expected return. Round your answer to two decimal places. % b. Calculate the stock's standard deviation. Round your answer to two decimal places. c. % Calculate the stock's coefficient of variation. Round your answer to two decimal places. Problem 8-2 Portfolio beta An individual has $20,000 invested in a stock with a beta of 0.3 and another $30,000 invested in a stock with a beta of 1.5. If these are the only two investments in her portfolio, what is her portfolio's beta? Round your answer to two decimal places. Problem 8-3 Required rate of return Assume that the risk-free rate is 4% and the expected return on the market is 13%. What is the required rate of return on a stock with a beta of 0.4? Round your answer to two decimal places. % Problem 8-4 Expected and required rates of return Assume that the risk-free rate is 5.5% and the market risk premium is 6%. a. What is the expected return for the overall stock market? Round your answer to two decimal places. b. What is the required rate of return on a stock with a beta of 1.5? Round your answer to two decimal places. % % Problem 8-5 Beta and required rate of return A stock has a required return of 12%; the risk-free rate is 6%; and the market risk premium is 5%. a. b. I. II. III. IV. V. What is the stock's beta? Round your answer to two decimal places. If the market risk premium increased to 8%, what would happen to the stock's required rate of return? Assume the risk-free rate and the beta remain unchanged. If the stock's beta is less than 1.0, then the change in required rate of return will be greater than the change in the market risk premium. If the stock's beta is greater than 1.0, then the change in required rate of return will be less than the change in the market risk premium. If the stock's beta is equal to 1.0, then the change in required rate of return will be greater than the change in the market risk premium. If the stock's beta is equal to 1.0, then the change in required rate of return will be less than the change in the market risk premium. If the stock's beta is greater than 1.0, then the change in required rate of return will be greater than the change in the market risk premium. New stock's required rate of return will be decimal places. %. Round your answer to two
