Question: A five-year bond with a yield of 10% (continuously compounded) pays a 7% coupon at the end of each year.
What is the bond's price?
What is the bond's duration?
Use the duration to calculate the effect on the bond's price of a 0.2% decrease in its yield.
Recalculate the bond's price on the basis of a 9.8% per annum yield and verify that the result is in agreement with your answer to (c).
