(a) Calculate the expected rate of return, variance and standard deviation of bond and common stock. (b) Do you think the above stocks and bonds is a good combination to form an investment portfolio? Explain why.(c) Assuming you invest in the portfolio with weights of 70% in stock and 30% in bonds. What are the expected rate of return and standard deviation of the portfolio?
You are forming an equally weighted portfolio of stocks. Many stocks have the same beta of 0.84 for Factor 1 and the same beta of 1.69 for Factor 2. All stocks also have the same expected return of 11 percent. Assume a two-factor model describes the return on each of these stocks. a) Write the equation of the returns on your portfolio if you place only five stocks in it. b) Write the equation of the returns on our portfolio...
