Time-weighted return. Related Articles. Time-weighted returns is a measure of the compound rate of return of a portfolio over a stated period of time. It requires a set of sub-period returns to be calculated whenever there is an external cash flow, such as a deposit or withdrawal from the portfolio.
For a set of all-positive fixed cash flows the weighted average will fall between 0 (the minimum time), or more precisely (the time to the first payment) and the time of the final cash flow. The Macaulay duration will equal the final maturity if and only if there is only a single payment at maturity.
