What are the YTM of these two bonds?
Bond 1. 100,000 bonds with a coupon
rate of 8% (paid semi-annually), a price quote of 120.0 and have 30
years to maturity. The semi-annual YTM is 3.24%.
Bond 2. 100,000 zero coupon bonds
(semi-annual compounding) with a price quote of 30.0 and 20 years
until maturity.
1)
No of periods = 30 years * 2 = 60 semi annual periods
Coupon per period = (Coupon rate / No of coupon payments per year) * Face value
Coupon per period = (8% / 2) * $100
Coupon per period = $4
Let us compute Yield to Maturity(YTM)
Bond Price = Coupon / (1 + YTM / 2)period + Face value / (1 + YTM / 2)period
$120 = $4 / (1 + YTM / 2)1 + $4 / (1 + YTM / 2)2 + ...+ $4 / (1 + YTM / 2)60 + $100 / (1 + YTM / 2)60
Using Texas Internements BA 2 plus calculator
SET N = 60, PV = -120, FV = 100, PMT = 4
CPT --> I/Y = 3.2398
Yield to Maturity(YTM) = 2 * I/Y
Yield to Maturity(YTM) = 2 * 3.2398%
Yield to Maturity(YTM) = 6.4796%
2)
No of periods = 20 years * 2 = 40 semi annual periods
Bond Price = Face value / (1 + YTM / 2)period
$30 = $100 / (1 + YTM / 2)40
(1 + YTM / 2)40 = $100 / $30
(1 + YTM / 2)40 = 3.3333
(1 + YTM / 2) = (3.3333)(1 / 40)
(1 + YTM / 2) = 1.030557
YTM / 2 = 0.030557
YTM = 2 * 0.030557
Yield to Maturity(YTM) = 6.1114%
We can also calculate the YTM through the financial calculator
Using Texas Internements BA 2 plus calculator
SET N = 40, PV = -30, FV = 100, PMT = 0
CPT --> I/Y = 3.0557
Yield to Maturity(YTM) = 2 * I/Y
Yield to Maturity(YTM) = 2 * 3.0557%
Yield to Maturity(YTM) = 6.1114%
