Dear friends pls provide any other formula or shortcut method to understand this problem
The answer given in suggested answer is so confusing
Both the bonds have a face value of ` 1,000 and coupon rate of 8% (with annual interest
payments) and both are selling at par. Assume that the yields of both the bonds fall to
6%, whether the price of bond will increase or decrease? What percentage of this
increase/decrease comes from a change in the present value of bond’s principal amount
and what percentage of this increase/decrease comes from a change in the present
value of bond’s interest payments?
(b) Consider a bond selling at its par value of ` 1,000, with 6 years to maturity and a 7%
coupon rate (with annual interest payment), what is bond’s duration?
(c) If the YTM of the bond in (b) above increases to 10%, how it affects the bond’s duration?
And why? (8+6+3 Marks) (June 2009)(S)
