嗨,爱思考的PZer你好:
经过我们教研组老师讨论,这个例题的4个答案都是存在问题的,但是原版书一直没有勘误,所以我们就保留这道题,讲解了解题方法,相近的练习,请参考Reading 6 课后题18。
这道题是Reading 6 ■ Principles of Asset Allocation的example11
我们先查表,得到
Module A and that the appropriately adjusted expected return for that module is 2.3%. Discounting a US$500,000 annual cash flow, inflated by 2% a year from Year 2 onwards。
也就是5年现金流是500,000, 回报为2.3%, inflation 是2%求现值,第二年才有Inflation。
PMT = 500,000, N= 5, I = 1.023/1.02-1
算出来是2478092,因为第二年才inflation 所以得出的数字需要除以1.02 也就是2429502。投资我们取千位也就是2430000。
They want an 85% chance of being able to maintain their current expenditures over the ensuing 25 years, which they see as a reasonable estimate of their joint life expectancy.
Goal 2 关键词:85% probability of success,25years。通过查表,选择F portfolio,minimum expected return=6.1%。因为要除去前5年,从第六年开始,
因此算出PMT = 500,000, N= 25, I =1.061/1.02-1
PMT = 500,000, N= 5 ,I =1.061/1.02-1
再减掉前5年的PV,得出PV
Goal 3 已知N=10,I/Y=4.1,FV=10million,CMT PV=6,691,026 书上给的答案没有参考价值哈。
