问题如下:
Leah informs Molly that DFC has a single $500 million liability due in nine years, and she wants SD&R to construct a bond portfolio that earns a rate of return sufficient to pay off the obligation. Leah expresses concern about the risks associated with an immunization strategy for this obligation. In response, Molly makes the following statements about liability-driven investing:
Which
of Molly’s statements about liability-driven investing is (are) correct?
选项:
A.Statement 1 only.
Statement 2 only.
Both Statement 1 and Statement 2.
解释:
Correct Answer: C
C is correct. Molly is correct that measurement error can arise even in immunization strategies for Type 1 cash flows, which have set amounts and set dates. Also, a parallel shift in yield curves is a sufficient but not a necessary condition to achieve the desired outcome. Non-parallel shifts as well as twists in the yield curve can change the cash flow yield on the immunizing portfolio; however, minimizing the dispersion of cash flows in the asset portfolio mitigates this risk. As a result, both statements are correct.
minimizing the dispersion of cash flows in the asset portfolio mitigates this risk(非平行移动)
之前有个知识点是laddered portfolio,它的优点就是 现金流 比较均匀的分布在收益率曲线上,对收益率曲线非平行移动有一定的抵抗作用。
但是答案又说 最小化现金分散度 可以缓解非平行移动的风险。 那感觉怎么是矛盾的呢?最小化现金分散度不就是bullet,那上面那个又是laddered,那请问到底那个可以抵抗非平行移动带来的风险?
