Mutual fund rolling returns are returns measured over consecutive time periods within a given time frame.
For example, a mutual fund’s one-month rolling returns can be calculated on a regular basis for the previous year.
The first rolling return will run from March 1, 2020 to March 31, 2020, the second from March 2, 2020 to April 1, 2020, and so on for the whole year.
Rolling returns are more dynamic than trailing returns, which are essentially a point-to-point estimate of returns.
Average rolling returns can be calculated by averaging a year’s range of rolling returns.
