问一道题:NO.PZ2019011501000003 [ CFA III ]

问题如下:

Based on the information below, calculate the time weighted rate of return of this portfolio for the first quarter of 2018 using the calculation methodology of revaluation at the time of large external cash flows (assume "large" is defined as larger than 5%).

选项:

A.

10.05%

B.

38%

C.

33.28%

解释:

C is correct.

考点:2.A Calculation Methodology

解析:这种方法将总的业绩衡量期限根据large cash flow拆分成了subperiod。Subperiod的收益率仍然是按照R=(EMV-BMV)/BMV计算,最后再几何链接计算总收益率。

Jan:

RJan1-15=(510,000-500,000)/500,000=2%

RJan16-31=(600,000-560,000)/560,000=7.14%

RJan1-31=(1+2%)(1+7.14%)-1=9.28%

Feb:

RFeb=(680,000-600,000)/600,000=13.33%

Mar:

RMar1-19=(700,000-680,000)/680,000=2.94%

RMar20-31=(690,000-660,000)/660,000=4.55%

RMar1-31=(1+2.94%)(1+4.55%)-1=7.62%

RQuarter=(1+9.28%)(1+13.33%)(1+7.62%)-1=33.28%

什么情况用TWRR 什么情况用EMV-BMV呢?我好像弄混了

嗨,爱思考的PZer你好:


Original Dietz method和Modified Dietz method计算monthly return都是直接调整现金流权重,前者统一用0.5,后者按时间权重计算。得到每月return之后,计算季度或者年度return用Geometric Linking。

Daily valuation method在计算monthly return的时候是按现金流分段计算return:

“It breaks the total performance period into subperiods that are defined by the occurrence of major cash flows.”

得到subperiod return后再用Geometric Linking计算出月度的return。计算季度和年度return跟其他方法一样,都是Geometric Linking
