老师你好,关于surplus optimization 和 hedging/return seeking portfolio的区别,讲课的时候给了两个区别,一个是surplus用来hedge liability的asset和liability之间一定有correlation,另一个是surplus不一定一定要求有overfund plan。 除此之外,请问针对surplus资产追求excess return是否有区别,surplus比较明确是针对asset - liability的资产做MVO,但是没有讲hedging/return seeking portfolio用来追求excess return的资产到底用哪种方法。

同学,你好: 除此之外,针对surplus资产追求excess return 基本没有区别。
Hedging/Return-Seeking Portfolio Approach,在这个方法中,the liability-relative asset allocation task is divided into two parts:1) In the basic case, the first part of the asset allocation task consists of hedging the liabilities through a hedging portfolio. 2)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.(主要使用的方法是 using mean–variance optimization method)
