嗨,努力学习的PZer你好:
C 这道题虽然提示了cash flow 发生在月末,但是让求annual return,也没有必须说让先求monthly return再折到年化. 所以直接用年的数据可以吗?
- 文中有一处关键句子在“in equal monthly installments”,所以我们每一期是一个月,所以PMT是72,000/12=6,000, N=10*12=120,如果不化成月份,那么算出来的数不对。
D. shortcoming: 我写的是用historical data不能够准确预测capital gain的发生. 没提到future financial market environment 这样写够吗?
- 同学做题之前看下我们的不用做清单,关于蒙特卡罗模拟的考点已经被协会移除了考纲,所以不用做这题。
E. 我的答案是: increase longevity risk. DB plan offers perpetual payment until Mattison's death. The longevity risk is zero. However, under DC plan, Mattison invests by himself. If he invests unsuccessfully, he will suffer loss. Besides, he only receives an one-time sum of money. If he lives longer, the higher the probability of having no enough money. 请问这么写的话,能拿到几分??对着看答案还是不太明白踩分点............
- 我个人认为你这样写没问题,大概两分吧,因为你有的地方有些问题。(本题三分钟,我假设一分钟算一分)
- 结论:increase longevity risk
- 证据:Since Mattison will move to DC plan
- 解释:under DC plan, Mattison invests by himself. If he invests unsuccessfully, he will suffer loss. If he lives longer, there would be a higher the probability of having no enough money to cover living expense.(这段就是你的原话,我只是做了一点点修改)
- 个人认为你可以把Besides, he only receives a one-time sum of money,因为under DC plan,雇主给你往账户里交钱,你自己进行投资,并不是只会收到一笔钱。
