An investor with investment horizon of 10 years purchases a 12-year, semiannual coupon bond with coupon rate of 7.82%, yield to maturity of 7.24%, and face value of $1,000. Just after buying the bond, the yield to maturity falls to 6.12% and stays at that level throughout the investment horizon. Calculate the investor's realized return if he reinvests his coupons to his investment horizon and sells the bond at that time.
