老师你好,请教一个关于reading 13的课后题,reading 13的课后第5题。客户Kealoha的目标是“earn a competitive risk adjusted rate of return while maintaining a high level of certainty to fix the obligation"。 这道题我凭借感觉选的是C,two approaches method,但是为什么不能选A surplus 呢? 我的笔记记录surplus 和two approaches method有两个区别,一个是surplus用来hedge liability的asset要和liability有相关性;第二个是two approaches的方法中的basic form要求overfunded。 但是我觉得这两个区别不能帮我判断这道题为什么不能选择surplus。

同学,你好:Hedging/return-seeking portfolios approach 指:This approach involves separating assets into two groups: a hedging portfolio and a return-seeking portfolio.
更详细的理解是:
In the basic case, the first part of the asset allocation task consists of hedging the liabilities through a hedging portfolio.
In the second part, the surplus (or some part of it) is allocated to a return-seeking portfolio, which can be managed independently of the hedging portfolio (for example, using mean–variance optimization or another method).
surplus optimization 指: mean–variance optimization applied to surplus (defined as the value of the investor’s assets minus the present value of the investor’s liabilities)
以上是两者的定义,再来分析 Kealoha 的情况,has a large fixed obligation due in 10 years / has substantially more funds than are required to meet the fixed obligation / earn a competitive risk-adjusted rate of return
可以判断出 Kealoha 有2个要求 1) 要安全 2) 收益要高
所以,Hedging/return-seeking portfolios approach 更好
