为什么用105%*25m就是market value啊?不太理解,可以详细说一下不?

NO.PZ2019070101000093

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:

8%的债券,如果YTM下降10bp,价格变化是多少?

首先,计算coupon rate8%的债券的市值:

market value=价格*权重*面值=105×0.25×1,000,000=26,250,000

再计算价格变动,YTM change=-10bp=-0.001

price change$

=[(-effective duration*YTM change)+(1/2*convexity*(YTM change2)]*market value

=[(-8×-0.001) + (0.5×122×0.0012)] *26,250,000 = $211,601.25

不理解market value,是现在的市场价值吗?为什么这么求出来的?

嗨,努力学习的PZer你好:


先看第一行数字,25million指的是面值。

那个105指的是,对于100美元面值的债券,市场价格是105美元,也就是 每1美元面值的市场价格 = 105/100 = 1.05美元。


现在一共有25million这么多的面值,那么一共的市场价格 = 25million * 1.05 = 26,250,000
