A 30-year maturity bond making annual coupon payments with a coupon rate of 16.3% has duration of 10.54 years and convexity of 161.2. The bond currently sells at a yield to maturity of 9%. a. Find the price of the bond if its yield to maturity falls to 8% or rises to 10%. (Do not round intermediate calculations. Round your answers to 2 decimal places.) YTM Price 8% $ 10% $ b. What prices for the bond at these new yields would be predicted by the duration rule and the duration-with-convexity rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.) YTM Duration Rule Duration-with- Convexity Rule 8% $ $ 10% $ $ c. What is the percent error for each rule? (Do not round intermediate calculations. Round "Duration Rule" to 2 decimal places and "Duration-with-Convexity Rule" to 3 decimal places.) Percent Error YTM Duration Rule Duration-with- Convexity Rule 8% % % 10% % % d. What do you conclude about the accuracy of the two rules? The duration-with-convexity rule provides more accurate approximations to the actual change in price. The duration rule provides more accurate approximations to the actual change in price.
