A 30-year maturity bond has a 7.4% coupon rate, paid annually. It sells today for $879.92. A 20-year maturity bond has a 6.9% coupon rate, also paid annually. It sells today for $888.1. A bond market analyst forecasts that in five years, 25-year maturity bonds will sell at yields to maturity of 8.4% and 15-year maturity bonds will sell at yields of 7.9%. Because the yield curve is upward sloping, the analyst believes that coupons will be invested in short-term securities at a rate of 4.2%.
