为什么不用算90节点的Fixed Coupon?

NO.PZ2019010402000011

问题如下:

A manger entered into a receive-fixed and pay-equity swap three months ago. The annualized fixed rate is 3% and equity index was at 100 when swap was entered. The maturity of swap is one year with quarterly reset, and notional amount is $100 million. The current spot rates are as follows:

Assume the equity index is currently trading at 101, the value of the swap is:

选项:

A.

320,450

B.

246,337

C.

-246,337

解释:

C is correct.

考点:equity swap求value.

解析:

首先画图:

一年期的swap,3个月之前进入的,所以时间轴如下,还剩3笔现金流。

对于equity leg来说,我们可以根据价格水平直接计算现在的value。

valueequity=(101/100)×100,000,000=101,000,000{\text{value}}_{equity}=(101/100)\times100,000,000=101,000,000

对于fixed leg来说,我们只用将三笔现金流折现即可。

Valuefixedleg=3%×(90360)×100000000×(0.997506+0.992556+0.985222)+100,000,000×0.985222=100,753,663Value_{fixedleg=}3\%\times(\frac{90}{360})\times100000000\times(0.997506+0.992556+0.985222) +100,000,000\times0.985222\\=100,753,663

Value of swap=-101,000,000+100,753,663=-246,337

嗨,努力学习的PZer你好:


这个是CFA官方出题的一种习惯,当题目告诉我们目前是处在利息支付日的时候,默认为当前的利息已经支付过了。所以未来只剩下三笔现金流。

就算太阳没有迎着我们而来,我们正在朝着它而去,加油!
