问一道题:NO.PZ2016031101000006

问题如下:

Use the information in the following table to answer this question (amounts in €):

Calculate the rate of return for this portfolio for January, February, March, and the first quarter of 1998 using revaluing for large cash flows methodology (assume "large" is defined as greater than 5%).

选项:

解释:

January:

RJan=(208,000200,000)/200,000=4.00%R_{Jan}=(208,000-200,000)/200,000=4.00\%

February:

lRFeb115=(217,000208,000)/208,000=4.33%RFeb1628=(263,000257,000)/257,000=2.33%RFeb128=[(1+0.0433)×(1+0.0233)]1=6.76%  {l}R_{Feb1-15}=(217,000-208,000)/208,000=4.33\%\\R_{Feb16-28}=(263,000-257,000)/257,000=2.33\%\\R_{Feb1-28}=\lbrack{(1+0.0433)}\times{(1+0.0233)}\rbrack-1=6.76\%\\\;

March:

lRMar121=(270,000263,000)/263,000=2.66%RMar2231=(245,000240,000)/240,000=2.08%RMar131=[(1+0.0266)×(1+0.0208)]1=4.80%{l}R_{Mar1-21}=(270,000-263,000)/263,000=2.66\%\\R_{Mar22-31}=(245,000-240,000)/240,000=2.08\%\\R_{Mar1-31}=\lbrack{(1+0.0266)}\times{(1+0.0208)}\rbrack-1=4.80\%

Quarter 1:

                             RQT1=[(1+0.0400)×(1+0.0676)×(1+0.0480)]1=16.36%R_{QT1}=\lbrack{(1+0.0400)}\times{(1+0.0676)}\times{(1+0.0480)}\rbrack-1=16.36\%

 (See Section 3.3 of the reading.)

这题的二月份收益为什么可以(1+r1)*(1+r2)? 我理解应该是 (1+r1/2)^(0.5)*(1+r2/2)^(0.5 = 1 + r(feb)

不需要将半个月收益转变成一个月收益吗

嗨,从没放弃的小努力你好:


同学你好,这里的RFeb1-15 / RFeb16-28分别求出的是15天的持有期收益率,并不是月度的收益率,用 (1+r1)*(1+r2) 是用几何平均的方式,把它转化成了月度的收益率。
