P4-24. A zero-coupon bond has a $1,000 face value, matures in ten years, and currently sells for $781.20. a. What is the market's required return on this bond? b. Suppose you hold this bond for one year and sell it. At the time you sell the bond, market rates have increased to 3.5%. What return did you earn on this bond? c. Suppose that rather than buying the ten-year zero-coupon bond described at the start of this problem, you instead purchased a ten-year 2.5% coupon bond (assume annual payments). Be- cause the bond's coupon rate equaled the market's required return at the time of purchase, you paid par value ($1,000) to acquire the bond. Again assume that you held the bond for one year, received one coupon payment, and then sold the bond, but at the time of sale the mar- ket's required return was 3.5%. What was your return for the year? Compare your answer here to your answer in part (b). -4-23. What is the price of a zero-coupon bond that has a par value of $1,000? The bond matures in thirty years and offers a yield to maturity of 4.5%. Calculate the price one year later, when the bond has twenty-nine years left before it matures (assume the yield remains at 4.5%). What is the return that an investor earns if they buy the bond with thirty years remaining and sell it one year later
