How Rolling returns works
Unlike one point-to-point return, they show how outcomes changed with the start date. Overlapping windows are not independent observations, so their percentage of positive outcomes is not a probability forecast.
The figure should always be read with its measurement period, product type and source. A precise-looking number can still answer the wrong question when two unlike products or time periods are compared.
An example
Five-year rolling returns measured monthly create a new five-year window for each month in the history, revealing the weakest, median and strongest starts.
Why it matters for your family
For dated goals, the worst and recovery periods may be more useful than the latest trailing return. Historical ranges still cannot guarantee a future result.
Connect the figure to a dated goal before acting. Money for an emergency or near-term payment has different constraints from retirement money, even when the product description quotes the same statistic.
