Suppose you buy a five-year zero-coupon Treasury bond for $800 per $1000 face value. Answer the following questions: (a) What is the yield to maturity (annual compounding) on the bond? (b) Suppose you buy the bond. Immediately after you buy it, the yield to maturity on comparable zeros increases to 7% and remains there. Calculate your annual return (holding period yield) if you sell the bond after one year. (c) Assume yields to maturity on comparable bonds remain at 7%. Instead of selling the bond after 1 year, as in (b), now you sell the bond after two years. Calculate your annual return. (d) Suppose after 3 years, the yield to maturity on similar zeros declines to 3%. Calculate the annual return if you sell the bond at that time. (e) If yield remains at 3%, calculate your annual return if you sell the bond after four years. (f) Calculate the annual return if you sell the bond after five years. (g) What explains the relationship between annual returns calculated in (b) through (f) and the yield to maturity in (a)
