duration match

NO.PZ2022090602000051

问题如下:

On page 2, Moynahan decides to outline the three total return approaches he utilizes to manage Reagan’s fixed-income portfolios. He puts together the following exhibit:

Exhibit 1 Features of Total Return Portfolios


How should Moynahan most likely label the management approaches for each of the portfolios described in Exhibit 1 on page 2 of his presentation?

Solutio

选项:

A.

Portfolio 1 = Active Management, Portfolio 2 = Pure Indexing, Portfolio 3 = Enhanced Indexing

B.

Portfolio 1 = Enhanced Indexing, Portfolio 2 = Pure Indexing, Portfolio 3 = Active Management

C.

Portfolio 1 = Active Management, Portfolio 2 = Enhanced Indexing, Portfolio 3 = Pure Indexing

解释:

A is correct. Moynahan should label the portfolios on page 2 as follows: Portfolio 1 = Active Management, which allows for larger risk factor mismatch to the benchmark. Portfolio 2 = Pure Indexing, which involves attempting to replicate a bond index as closely as possible. Portfolio 3 = Enhanced Indexing, which is closely linked to the benchmark but attempts to generate a modest amount of outperformance versus the benchmark.

B is incorrect because the ordering of portfolios given is incorrect. The correct ordering is: Portfolio 1 = Active Management, Portfolio 2 = Pure Indexing, Portfolio 3 = Enhanced Indexing.

C is incorrect because the ordering of portfolios given is incorrect. The correct ordering is: Portfolio 1 = Active Management, Portfolio 2 = Pure Indexing, Portfolio 3 = Enhanced Indexing.

请问下老师,这道题再判断duration是否match的时候,是key rate duration和credit spread duration都要和benchmark对比吗?

是的。

这道题就是判断Portfolio使用了pure indexing, enhanced indexing, active management里面的哪一个方法。

portfolio的所有指标,如果和index都基本一致,这说明就是Pure indexing。

Portfolio的所有指标里面,如果有一些指标略微地偏离了index,但整体指标都比较接近Index,这说明是enhanced indexing。

Portfolio整体上看,如果指标大幅偏离index,属于active。

在判断的时候,应该是要看所有指标的。所以像这道题,除了duration外,key rate duration,credit spread duration等等指标都需要和benchmark进行比较。

只不过实际在做题时,我们一般是主要观察duration,因为duration是最主要的风险指标,只要duration都偏离了index,那就直接否定pure indexing,从duration快速判断是一个比较快捷的方法。如果Duration分析不出来,再去看其他的指标。但一定是基于所有的指标综合分析的。
