Answer:
-8.13%
Step-by-step explanation:
The computation of the percentage change in the price of the bond is shown below;
Given that
Face Value = $1,000
Annual Coupon Rate = 6.7%
Semi-annual Coupon Rate = 3.35%
Semi-annual Coupon = 3.35% × $1,000 = $33.50
Now
After 2 years:
Annual YTM = 8.1%
Semi-annual YTM = 4.05%
Price of Bond = $33.50 × PVIFA(4.05%, 16) + $1,000 ×PVIF(4.05%, 16)
= $33.50 × (1 -(1 ÷ 1.0405)^16) ÷ 0.0405 + $1,000 ÷ 1.0405^16
= $918.73
Now
Change in Price = ($918.73 - $1,000) ÷ $1,000
= -8.13%
