You have a one-year investment horizon and want to choose among
three bonds. All three bonds have the same default risk, mature in
10 years, and have a face value of $1,000. The first is a
zero-coupon bond. The second has an 8% coupon rate (paid annually).
The third has a 10% coupon rate (paid annually).
a) If all three bonds are now priced to yield 8% to maturity, what
are their prices?
b) If you expect their yields to maturity to be 8% at the beginning
of next year, what will their prices be then? What is your rate of
return on each bond over the one-year holding period?
a)
Zero Coupon Bond:
Price = Face Value/[(1+Interest Rate)^Time to Maturity] = 1000/[(1+0.08)^10] = 1000/2.1589 = $463.2

Rate of Return:
Zero Coupon Bond = (Price after 1 year-Price today)/Price today = (500.25-463.2)/463.2 = 8%
8% Annual Coupon = (Price after 1 year-Price today+Coupon)/Price today = (1000-1000+80)/1000 = 8%
10% Annual Coupon = (Price after 1 year-Price today+Coupon)/Price today = (1124.94-1134.2+100)/1000 = 9.07%
