One year ago, you purchased a 10-year 8% annual coupon bond when the market interest rate on similar bonds was 6%. Today you received the first coupon payment, and the bond's yield to maturity is 5%. If you sell the bond today, what will be your holding period return?

12.73%

Explanation:

to determine the price paid for the bond last year we must add the present value of the annuity plus the present value of the bond's face value:

present value of an annuity = payment x {1 - [1 / (1 + r) ⁿ]} / r

present value of bond's face value = future value / (1 + r) ⁿ

payment = 80 future value = 1,000 n = 10 r = 6%

present value of an annuity = 80 x {1 - [1 / (1 + 6%) ¹⁰]} / 6% = $588.81

present value of bond's face value = 1,000 / 1.06¹⁰ = $558.39

market price of the bond last year = $588.81 + $558.39 = $1,147.20

to determine the current value of the bond we just adjust n = 9 and r = 5%

present value of an annuity = 80 x {1 - [1 / (1 + 5%) ⁹]} / 5% = $568.63

present value of bond's face value = 1,000 / 1.05⁹ = $644.61

current market price of the bond = $568.63 + $644.61 = $1,213.24

last year you invested $1,147.20 to purchase the bond and this year you received $80 (coupon) and $1,213.24 when you sold the bond. Your net profit = $1,293.24 - $1,147.20 = $146.04

holding period return = ($146.04 / $1,147.20) x 100 = 12.73%
