A 3-year $1000 face value bond pays an annual coupon of 8% and has a ytm of 4%. What is this bond's price? What is this bond's duration?
Coupon payment = 0.08 * 1000 = 80
Bond price = 80 * [ 1 - 1 / ( 1 + 0.04)3] / 0.04 + 1000 / ( 1 + 0.04)3
Bond price = 80 * 2.775091 + 888.996359
Bond price = $1,111.004
2)
Present value of year 1 cash flow = 80 / ( 1 + 0.04) = 76.9231
Present value of year 2 cash flow = 80 / ( 1 + 0.04)2 = 73.9645
Present value of year 3 cash flow = 80 / ( 1 + 0.04)3 = 71.1197
Present value of year 3 face value = 1000 / ( 1 + 0.04)3 = 888.9964
Total year 3 cash flow = 71.1197 + 888.9964 = 960.1161
Total present value = 76.9231 + 73.9645 + 960.1161 = 1,111.0037
Weight of year 1 cash flow = 76.9231 / 1,111.0037 = 0.069237
weight of year 2 cash flow = 73.9645 / 1,111.0037 = 0.066574
Weight of year 3 cash flow = 960.1161 / 1,111.0037 = 0.864188
Period 1 * weight 1 = 1 * 0.069237 = 0.069237
Period 2 * weight 2 = 2 * 0.066574 = 0.133148
Period 3 * weight 3 = 3 * 0.864188 = 2.592564
Duration = 0.069237 + 0.133148 + 2.592564
Duration = 2.79
