(a) An investment advisor states, "An investor's annualized holding period return from investing in a bond consists of three parts: the coupon interest payments, the return of principal, and any capital gain or loss that the investor realizes on the bond." Comment and explain if the advisor's opinion is correct or incorrect and why? (b) Charlie Smith holds two portfolios, Portfolio X and Portfolio Y. They are both liquid, well-diversified portfolios with approximately equal market values. He expects Portfolio X to return 13% and Portfolio Y to return 14% over the upcoming year. Because of an unexpected need for cash, Smith is forced to sell at least one of the portfolios. He uses the security market line to determine whether his portfolios are undervalued or overvalued. Portfolio X's beta is 0.9 and Portfolio Y's beta is 1.1. The expected return on the market is 12% and the risk-free rate is 5%. Smith should sell: 1) either portfolio X or Y because they are both properly valued. II) portfolio Y only. III) both portfolios X and Y because they both are overvalued. Select one option from the above and explain the rationale behind your selection
