3. (12 points) Suppose there are three possible states of the economy and estimates of the rates of return for Stocks A and B in each state are given in the table below. Economy Boom Normal Recession Probability 0.1 0.6 0.3 TA 20% 8% -4% a. Show that the expected return and the standard deviation of return of these two stocks are (, ) = (5.6%, 7.2%) and (BB) = (6.6%, 8.81%).. (4 marks) b. Consider a portfolio consists of 40% in stock A and 60% in stock B. TB -12% 4% 18% i). What is the expected return of the portfolio? ii). What is the standard deviation of return of the portfolio? D 4. (8 marks) Explain why portfolio risk (op) tends to decrease as the number of stocks in the portfolio increases. Key concepts to include in your answer: diversification, covariance of returns and specific risk. (Note: The is question is worth 8 marks, so I expect to see an "8 marks answer".) Stock Investment Beta A $100,000 1.50 B $150,000 -0.25 $250,000 1.25 $500,000 0.75 (4 marks) (4 marks) 5. (8 points) Bilibaba Inc.'s most recent dividend paid was $2.40 per share. The dividend is expected to grow at a rate of 6 percent per year in the foreseeable future. The risk- free rate is 5 percent and the return on the market is 9 percent. If the company's beta is 1.3 what is the price of the stock today? 6. (10 points) Consider the following 4-stock portfolio: The market required rate of return is 12 percent and the risk-free rate is 4 percent. a. Find the required rate of return of the portfolio. b. Find 3p, the beta of this portfolio. c. Use the portfolio 3 your obtained in part b. and the SML to verify that the required rate of return of the portfolio is the same as that in part a.
