20. You have been given this probability distribution for the return of Apple (AAPL). Probability Rate of Return 0.5 30% 0.5 10% a. What are the expected return and the standard deviation of AAPL? (7 points) b. Suppose the expected return and standard deviation of Amazon (AMZN) is 10% and 5%. The correlation between AAPL and AMZN is 0.71. And the optimal risky portfolio, P*, comprising of AAPL and AMZN, is investing 50% in each. What is the optimal risky portfolio's expected return and standard deviation? (11 points) c. Assume that you have a risk aversion parameter A = 4 and the risk-free rate is 8%. What is your optimal investment in P*? (4 points)
