Consider a 8% coupon bond making annual coupon payments with 4 years until maturity and a yield to maturity of 10%.
Please show how to do it and use excel if possible. thank you
SOLUTION:-
a.
Annual coupon rate | 8% |
Yield | 10% |
Settlement date | 4/10/2020 |
Muturity date | 4/10/2024 |
Payment frequency | 1 |
MDURATION function in excel |
3.237903803 |
b.
Annual coupon rate | 8% |
Old Yield | 10% |
Settlement date | 4/10/2020 |
Maturity date | 4/10/2024 |
Payment frequency | 1 |
Redemption value | 100 |
New yield | 10.75% |
Using function PRICE in excel | |
Bond Price at old yield = 10% | Bond Price at new yield = 10.75% |
93.66026911 | 91.42253393 |
Percentage change in bond price (91.4225 - 93.6602)*100/91.4225 = 2.4476% (decrease)
c. Change in bond price = Duration effect + convexity effect
= ( - Modified duration change in yield) + convexity * (change in yield)^2)
= ( - 3.2379*0.0075) + (0.5*14.13*0.0075*0.0075)
= -2.388%
New price using convexity - duration = 93.6602*(100-2.388)/100 = 91.4236
d. Percentage error = = 0.001203%
