Solution:
Since the bond are selling at par(i.e sale value and face value are same),hence interest rate(YTM) must be equal to coupon rate.Let the fair value(Maturity value) of bond is $1000
Accordingly if the interest rate rise by 2%(i.e 9%),then price of each bond is as follow;
Price of bond is the present value of coupon payable on it and its maturity value.Thus formula for calculating price of bond is;
=Coupon amount*[email protected] rate for given period+Maturity value*[email protected] interest rate for given period
Price of Bond Sam=$35*[email protected]% for 6 period+$1000*[email protected]% for 6th period
=$35*5.1579+$1000*0.7679
=$180.5265+767.90
=$948.42
%Change in price=($1000-$948.42/$1000)*100
=-5.16%
Price of Bond Dave=$35*[email protected] for 40 period+$1000*[email protected] for 40th period
=$35*18.40158+$1000*0.171929
=$644.06+171.93
=$815.98
%change in price=[($1000-$815.98)/$1000]*100
=-18.40%
b)If interest rate fall by 2%(i.e 5%),then price of;
Bond Sam=$35*[email protected]% for 6 period+$1000*[email protected]% for 6th period
=$35*5.508125+$1000*0.862297
=192.78+862.297
=$1055.08
%change in price=[($1000-$1055.08)/$1000]*100
=5.51%
Bond Dave=$35*[email protected]% for 40 period+$1000*[email protected]% for 40th period
=$35*25.10278+$1000*0.37243
=$878.59+$372.43
=$1251.02
%change in price=[($1000-$1251.02)/1000]*100
=25.10%
c)Interest rate risk is higher for Long term bond as compare to short term bond,which is clearly shown above.
