问题如下：
If the yield-to-maturity of Bond X increases by 50 bps, the expected percentage price change of Bond X is closest to:
选项：
A.
–1.792%
B.
–1.812%
C.
–1.832%
解释：
A is correct. The expected price change is calculated as follows:
%ΔPVFull ≈ (–3.6239 × 0.005) + [0.5× 16.2513 × (0.005)^2]
= –1.79164% ≈ –1.792%
为什么这个是large spread changes而不是small？
