原版书这个case后面的4个小题没有收录在题库是出于什么考虑?

问题如下:

If Winslow is allowed to hedge into any of the currencies, she can obtain the highest expected returns by

选项:

A.

buying the Greek 5-year in each portfolio and hedging it into Pesos.

B.

buying the Greek 5-year in each portfolio and hedging it into USD.

C.

buying the Mexican 5-year in each portfolio and not hedging the currency.

解释:

A is correct.

As shown in the previous question, the Greek bond is the most attractive. Although the Peso is expected to depreciate by 2% against the EUR and the GBP and by 1% against the USD, this is less than the benefit of hedging EUR into MXN (+3.475%). The net currency component of the expected return is +1.475% = (3.475% – 2.0%) for the EUR and GBP portfolios and +2.475% = (3.475% – 1.0%) for the USD-denominated portfolio. Hedging into GBP would add only 0.175% for any of the portfolios. Hedging into USD would reduce expected return for any of the portfolios because the pick up on the hedge (+0.625%) is less than the expected depreciation (–1.0%) of the USD against the Euro and GBP.

B is incorrect. Hedging the Euro-denominated Greek bond into USD would reduce expected return for any of the portfolios because the pick on the hedge (+0.625%) is less than the expected depreciation of the USD against the Euro and GBP.

C is incorrect. As shown above, the Greek bond is more attractive than the Mexican bond.

我在做原版书题的时候,发现这个case后面还有4个小题。一是在咱们题库没看到,二是原版书习题讲解也没有那几个题。我做的也晕晕的答案也看不明白。所以想请教一下。

嗨,努力学习的PZer你好:


“一是在咱们题库没看到,二是原版书习题讲解也没有那几个题。我做的也晕晕的答案也看不明白。所以想请教一下。”


这几道题协会在勘误里删除掉了。

主要是这道题的题干里面,表2收益率曲线的变动定义与我们所学的刚好相反。所以用表2做后面4道题,做出来的结果是错误的。因此协会删掉了,目前还没有勘误。


后面4道题对应的考点在基础班何老师是就着Reading 20这道例题进行展开的,可以参考Reading 20的基础班视频:


这里建议继续往前学,后期在固定收益的经典题里面,这道题的题干我们会修改正确,然后何老师会就着新的题干进行讲解。

就算太阳没有迎着我们而来,我们正在朝着它而去,加油!
