The table below contains information on two shares: X and Y. Ro is the realized one-year holding period period in the year just ended. E(R1) is the forecast return for the next year based on the performance of the company. The market risk premium is 8% and risk free rate is 2%. Shares X Y RO 12% 8% E(R) 10% 12% Beta 1.2 0.8 Standard Deviation 19% 22% a) For a new investor who only wants to invest in one of these two shares, which share should be picked? Explain. (2 marks) b) For an investor who has already been holding a well-diversified portfolio and only wants to add more shares if doing so will improve the portfolio's alpha. Should this investor invest in X or Y? Or both? Or neither? Explain. (2 marks) c) An investor has constructed a risky portfolio Z by combing X and Y. Portfolio Z has an expected return of 11.6% and a standard deviation of 18%. If the investor wants to further combine portfolio Z with the risk- free asset to maximize expected return while having a standard deviation not higher than 15%, what should be the weights of X, Y and the risk free asset? (use E(R1) in the table as the forecast expected return for share X and Y to determine their weights in Z) (4 marks) d) If CAPM holds, how are investors expected to trade shares X and Y based on the values you have calculated in part b)? What will happen to the price of X and Y if there is no new information to be revealed to market? Explain. (2 marks)
