5-10The Brownstone Corporationâs bonds have 5 years remaining to maturity. Interest is paid annually, the bonds have a $1,000 par value, and the coupon interest rate is 9%.a. What is the yield to maturity at a current market price of (1) $829 or (2) $1,104?b. Would you pay $829 for one of those bonds if you thought that the appropriate rate of interest was 12%-that is, if r d = 12%? Explain your answer.5-21Suppose Hillard Manufacturing sold an issue of bonds with a 10-year maturity, a $1, 000 par value, a 10% coupon rate, and semiannual interest payments.a. Two years after the bonds were issued, the going rate of interest on bonds such as these fell to 6%. At what price would the bonds sell?b. Suppose that, 2 years after the initial offering, the going interest rate had risen to 12%. At what price would the bonds sell?c. Suppose, as in part a, that interest rates fell to 6% 2 years after the issue date. Suppose further that the interest rate remained at 6% for the next 8 years. What would happen to the price of the bonds over time?6-7Suppose rRF= 9%, r m = 14%, and bi = 1.3a. What is ri, the required rate of return on Stock i?b. Now suppose rRF (1) increases to 10% or (2) decreases to 8 %. The slope of the SML remains constant. How would this affect rM and ri?c. Now assume rRFremains at 9% but rm (1) increases to 16% or (2) falls to 13%. The slope of the SML does not remain constant. How would these changes affect ri?6-9Suppose you manage a $4 million fund that consists of four stocks with the following investments:StockInvestmentBetaA$4000,0001.50B600,000-0.50C1,000,0001.25D2,000,0000.75If the marketâs required rate of return is 14% and the risk-free rate is 6%, what is the fundâs required rate of return.
