let A be the fund balance onjanuary 1, B the balance on june 30, and C the balance on december 1.
a) if there are no deposits or withdrawals, show that yield rates computed by the dollar-weighted method and the time-weighted methodare both equal to (C- A)/A.
b) if there was a single deposit of D immediately after the june 30 balance was calculated, fund expression for the dollar-weighted yield rates.
c) rework (b) if thedeposit occurred immediately before the june 30 balance was calculated.
d) verbally interpret the fact that the dollar-weighted yield rates in (b) and (c) are equal.
e) show that the time-weighted yieldrate in (b) is greater that in (c)
