An analyst gathers the following information ($ millions) about the performance of a portfolio:
Quarter
Value at Beginning
of Quarter
(prior to inflow or outflow)
Cash Inflow (Outflow)
At Beginning of Quarter
Value at End
of Quarter

The portfolio’s annual time-weighted rate of return (%) is closest to:
A. 8.
B. 27.
C. 32.
Answer: C
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 × 0.9286 × 1.3333 × 0.9762) - 1 = 1.3185 – 1 = 0.3185 or 31.85%.
Can anyone explain to me how they got 4.1/4.2?
 
Cash flow is at beginning of quarter.
So HPR for each quarter = Value at End / (Value at beginning + Cash Flow in quarter)
so for quarter 1
Quarter
Value at Beginning of Quarter (prior to inflow or outflow)
Cash Inflow (Outflow) At Beginning of Quarter
Value at End of Quarter

4.1 / (3.2 + 1 ) = 4.1 / 4.2
