RETURNS CALCULATION/MEASURE
Holding period : is the return earned on an asset during the period it was held. It os calculated as the
sum of price appreciation and periodic income.
A capital gain of 5 percent and a dividend yield of 2 percent is computed in the example.
What is the 3-year holding period return if the annual returns are 7%, 9%, and –5%?
When assets have returns for multiple holding periods, we should aggregate those returns into one
overall return for ease of comparison and understanding.
Arithmetic Mean: the average of all holding period returns. Assume you have three stocks A, B, C with
returns 10%,20%,30%. Return on stock would be (10+j20+30)/3=20%.
Geometric Mean: it is always greater than or equal to Arithmetic return.
Money weighted return
Is the internal rate of return on money invested that considers the cash flows and calculates actual
investment. The internal rate of return is the discount rate at which the sum of present values of these
cash flows will equal zero.
