Question

I am not able to replicate the chart for a 30 year bond using the example from the previous page.

INTEREST RATE RISK
Pg 169
the amount of risk a bond has is dependant on
0 remaining time to maturity.
2 coupon rate
GENERAL RULE
4
the longer the maturity the greater the interest rate risk
the lower the coupon rate, the the risk

EXAMPLE
6.1 Semiannual Coupons
in practice, bonds issued in the United States usually make coupon payments twice a year. So, if an
ordinary bond has a coupon rate of 14 percent, then the owner will get a total of $140 per year, but
this $140 will come in two payments of $70 each. Suppose we are examining such a bond. The
yield to maturity is quoted at 16 percent.
Bond yields are quoted like APRs; the quoted rate is equal to the actual rate per period mult
plied by the number of periods. In this case, with a 16 percent quoted yield and semiannual pay
ments, the true yield is 8 percent per six months. The bond matures in seven years What is the
bond's price? What is the effective annual yield on this bond?
Based on our discussion, we know that the bond will sell at a discount because it has a cou
pon rate of 7 percent every six months when the market requires 8 percent every six months. So, if
our answer is equal to or exceeds $1,000, we know that we have made a mistake.
To get the exact price, we first calculate the present value of the bond's face value of $1,000
paid in seven years. This seven-year period has 14 periods of six months each. At 8 percent per
period, the value is:
Present value $1,000/1.08 $1,000/2.9372 = $340.46
The coupons can be viewed as a 14-period annuity of $70 per period. At an 8 percent discount rate,
the present value of such an annuity is
Annuity present value = $70 x (1-1/1.08.08
=$70 x (1-3405.08
-$70 x 8.2442
-$57710
The total present value gives us what the bond should sell for:
170
Total present value-$340.46 +57710-$917.56
To calculate the effective yield on this bond, note that 8 percent every six months is equivalent to
Effective annual rate= (1+08-1-16.64%
The effective yield, therefore, is 16.64 percent
