The correct answer is D
Since the bond is selling at par, it’s yield = coupon rate = 8%.
V0 = Par = 100.
For convexity, change in yield used in calculations is arbitrary – so we use 100 bps in our calculations below.
I/Y = 7.00; FV = 100; N = 12; PMT = 0.08 x 100 = 8; PV = V- = 107.94
I/Y = 9.00; FV = 100; N = 12; PMT = 0.08 x 100 = 8; PV = V+ = 92.84
convexity = (107.94+92.84-200)/(100x0.012)= 78 |
