问题如下:
The table provides relevant information about four bonds in a portfolio, based on the table, the price change for the 8% bond using effective duration if its YTM decreases by 10 basis points is close to?
选项:
A.$211,601.25.
B.$223,532.12.
C.$219,156.99.
D.$209,111.50.
解释:
A is correct
考点:Bond Duration-DV01
解析:
对于8% bond:
market value=105×0.25×1,000,000=26,250,000
[(-8×-0.001) + (0.5×122×0.001^2)] *26,250,000 = $211,601.25
[(-8×-0.001) + (0.5×122×0.001^2)] *26,250,000 = $211,601.25
这是用的什么公式呀。正常的公式不是应该change of P = -D*P*change of y+0.5*C*(change of y)^2 求吗。后面的(0.5×122×0.001^2) 我看懂了是对于convecity的,前面的那个部分是怎么算的呢,不是应该-8*1.05*(-0.001) 吗
