A 30-year maturity bond making annual coupon payments with a coupon rate of 11.2% has duration of 11.63 years and convexity of 195.34. The bond currently sells at a yield to maturity of 8%.
a. Find the price of the bond if its yield to maturity falls to 7%. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
b. What price would be predicted by the duration rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
c. What price would be predicted by the duration-with-convexity rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
d-1. What is the percent error for each rule? (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)
d-2. What do you conclude about the accuracy of the two rules?
The duration-with-convexity rule provides more accurate approximations to the true change in price or The duration rule provides more accurate approximations to the true change in price.
e-1. Find the price of the bond if its yield to maturity increases to 9%. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
e-2. What price would be predicted by the duration rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
e-3. What price would be predicted by the duration-with-convexity rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
e-4. What is the percent error for each rule? (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)
