A 1 0 year annual coupon bond has a face value of $ 1 0 0 and an annual coupon of $ 3 . Assume

A 10 year annual coupon bond has a face value of $100 and an annual coupon of $3.
Assume that the yield to maturity of the bond is 5% and that the yield curve is flat.

(a) Calculate the Macaulay and modified duration of the bond.
(b) Calculate the approximate and exact changes in price of this bond if the interest
rate change is 0.02%(i.e.,y =0.0002).
(c) Calculate the approximate and exact changes in price of this bond if the interest
rate change is 2%(i.e.,y =0.02).
(d) Briefly explain the difference between the results from (b) and (c). Can you draw
any implication for hedging with duration?
(e) You just short-sold (one unit of) the 10 year coupon bond, but now you feel
nervous. You would like to hedge against this short position. Suppose that you
can trade a 2-year zero coupon bond and a 20-year zero coupon bond by any
amount without any transaction cost. Using the proceeds from the short sale,
how can you combine these two zero coupon bonds to immunize your position
against interest rate risk?A 10 year annual coupon bond has a face value of $100 and an annual coupon of $3.
