The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.
The time-weighted return (TWR) [1] [2] is a method of calculating investment return, where returns over sub-periods are compounded together, with each sub-period weighted according to its duration. The time-weighted method differs from other methods of calculating investment return, in the particular way it compensates for external flows.
The result of this application of a weight function is a weighted sum or weighted average. Weight functions occur frequently in statistics and analysis , and are closely related to the concept of a measure .
An exponential moving average (EMA), also known as an exponentially weighted moving average (EWMA), [5] is a first-order infinite impulse response filter that applies weighting factors which decrease exponentially. The weighting for each older datum decreases exponentially, never reaching zero. This formulation is according to Hunter (1986). [6]
Time-weighted return calculates a fund’s compound return using sub-periods, which are created each time cash moves into or out of the fund or portfolio. In doing so, TWR shows the real market ...
The dual use of the word "duration", as both the weighted average time until repayment and as the percentage change in price, often causes confusion. Strictly speaking, Macaulay duration is the name given to the weighted average time until cash flows are received and is measured in years. Modified duration is the name given to the price ...

A time-weighted average is any of the following: Permissible exposure limit, a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as loud noise. Time-weighted average price, the average price of a security over a specified time.
