1. A 25-year, 5% coupon bond, pays interest semi-annually, and
is priced to yield 5%.
a. What is its approximate modified duration for 100bps change
in yield?
b. What is its approximate convexity for 100bps change in
yield?
c. Using its approximate modified duration alone, how much (in %
terms) do you expect the price of this bond to change if interest
rates increase by 200bps?
d. Using its modified duration and convexity, how much (in %
terms) do you...
