问一道题:NO.PZ2017012501000010

问题如下:

The tranches in a collateralized mortgage obligation (CMO) that are most likely to provide protection for investors against both extension and contraction risk are:  

选项:

A.

planned amortization class (PAC) tranches  

B.

support tranches.   

C.

sequential-pay tranches.

解释:

A is correct.

PAC tranches have limited (but not complete) protection against both extension risk and contraction risk. This protection is provided by the support tranches. A sequential-pay tranche can protect against either extension risk or contraction risk but not both of these risks. The CMO structure with sequential-pay tranches allows investors concerned about extension risk to invest in shorter-term tranches and those concerned about contraction risk to invest in the longer-term tranches.

这题在经典题中,但是少了for investor,是不是应该选B。答案是不是有问题

建议助教们先去investopedia好好把各种概念、分类、逻辑关系搞清楚再来回答问题。这种随意的答复,太误导学员了。

同学您好,

这题选A,是一样的题目,只有investor 面临extension and contraction risk。就算少了这个词,这一题默认的还是for investor.

确实只有investor面临extention and contraction risk。所以support tranch是提供保护的,investor是面临保护的
