嗨,努力学习的PZer你好:
这道题不规范哈,因为另外一个Portfolio的Macaulay duration差的太离谱了。直接根据macaulay duration就选出来了。
考试的话建议3个条件都写上,但一般绝大多数题目不给PV,或者默认PV是满足条件的,所以基本就是把duration和convexity的条件都写上。针对这道题,写满就是:
to build a single liability duration-matching strategy, the asset macaulay duartion should equal to liability's due date and the asset's convexity should be as low as possible.
Portfolio X' s macaulay duration of 4.98 closely matches liability due date, and portfolio x has a relative lower convexity compared with portfolio y.
分数不一定是平分的,几个小问合起来12分。
考试的话,会给3个及以上portfolio让选最优,仅仅根据一个条件选不出来最优,所以条件要写全,即便能利用一个条件选出来,也要写全,针对考试尽可能写完整哈。
