An investment has the following payoffs: $50 in one year, $50 in two years, $50 in three years, and $1,050 in four years. The investment has a YTM of 4%. Calculate the duration (Macaulay duration, not modified duration).
Give your answer to two decimal places.
Year (x) | Cash flow | Present value (w) | wx |
1 | 50 |
50 / 1.04 = 48.08 |
48.08 |
2 | 50 |
50 / 1.042 = 46.2278 |
92.4556 |
3 | 50 |
50 / 1.043 = 44.45 |
133.35 |
4 | 1050 |
1050 / 1.044 = 897.54 |
3590.16 |
1036.3022 | 4761.59 |
Macauley Duration = Sum of Wx / Sum of W
= 4761.59 / 1036.3022
= 4.60 years Answer
