The time-weighted rate of return is calculated by computing the quarterly holding period returns and linking those returns into an annual return. In this case, the quarterly holding periods are 2.4/2.2 = 1.0909, 2.6/2.8 = 0.9286, 3.2/2.4 = 1.3333, and 4.1/4.2 = 0.9762. The time-weighted return is thus (1.0909 作者: JoeyDVivre 时间: 2011-7-11 19:58
I answered this in some other thread.
The time weighted return is stated yearly and not quarterly. Thats why.
So if my HPY for 7 months is 6% and the remaining 5 months is 5% , my annual return is
1.06 x 1.05 -1 = 11.3%
Now if these returns are stated semi- annually, you have to do treat them as 2 6 month periods.

woah...... i totally did not know this....作者: thisisbrianly 时间: 2011-7-11 19:58
Sorry guys but can you guys please elaborate on that? I mean why didn't we do the ^1/4???
if its stated yearly we don't needed??? so when do we needed?
Thanks in advance作者: Micholien 时间: 2011-7-11 19:58
you will need to do 1/4 if they had asked for the time-weighted quarterly return given the returns of the 4 quarters.作者: chetan86 时间: 2011-7-11 19:58
I'm confused on this as well. :s作者: dmar 时间: 2011-7-11 19:58
it's really not as bad as it looks...
Basically, you raise the product to: x/y, where:
x = number of periods over which we want the time-weighted return over
y = sum of periods covered by the component returns
much easier to explain with actual numbers. So taking the original example:
x = 12 months (coz we want the annual time-weighted return)
y = 12 months (4 quarters)
so you raise it by 12/12 = 1.
if we wanted to calculate the ANNUALIZED time-weighted return, given returns from SIX quarters:
x = 12 (coz, annual)
y = 18 (6 quarters)
so, we'd raise the product by: 12/18 = 0.67作者: johnnyBuz 时间: 2011-7-11 19:58
