不理解答案。
题干里statement 2哪里说要minimize dispersion了?我理解的是一般情况下是会存在nonparallel shift带来的问题的。所以我觉得statement 2不对 。
答案说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,可以这个statement又不是说如何避免nonparallel shift带来的问题的。
不理解,请求解答,谢谢
