问题如下:
At the beginning of Year 1, a fund has $10 million under management; it earns a return of 14% for the year. The fund attracts another $100 million at the start of Year 2 and earns a return of 8% for that year. The money-weighted rate of return is most likely:
选项:
A.less than the time-weighted rate of return.
B.the same as the time-weighted rate of return.
C.greater than the time-weighted rate of return.
解释:
A is correct.
The money-weighted rate of return is found by setting the present value (PV) of investments into the fund equal to the PV of the fund’s terminal value. Because most of the investment came during Year 2, the measure will be biased toward the performance of Year 2. Set the PV of investments equal to the PV of the fund’s terminal value: Solving for r results in r = 8.53%. The time-weighted return of the fund is =
为什么这一题就要开平方,而上一题算over the there years 就不开三次方?该题目中哪里可以看出是问的每年的而不是over the two years?
