Rolling returns vs point-to-point: the honest way to judge a fund

When a fund advertises "18% over 5 years," that single number hides a trap: it depends entirely on the one start date used. Pick a start date at a market bottom and any fund looks brilliant; pick a peak and the same fund looks poor. Rolling returns fix this.

Point-to-point returns (the flattering version)

A trailing return measures NAV on one start date vs one end date. "5-year return as of today" uses exactly two data points. Move the start by six months and the number can change dramatically — not because the fund changed, but because the market's starting level did. That's why an advertised return is a sales figure, not an analysis.

Rolling returns (the honest version)

Rolling returns compute the return for every possible start date over a window, then look at the whole distribution.

Example: "5-year rolling returns over the last 10 years" takes every 5-year period — Jan 2016→Jan 2021, Feb 2016→Feb 2021, and so on, stepping monthly — and gives you not one number but a range:

• Average 5-year return across all those periods
• Best and worst 5-year period an investor actually lived through
• How often the fund beat, say, 12% — its consistency

A fund that returned 14% every rolling 5-year period is far more dependable than one that averaged 14% by swinging between −5% and +35%, even though the headline "average" looks the same.

What to look for

• A high floor. The worst rolling period tells you the pain you'd have to sit through. A fund whose worst 5-year stretch is still positive is sturdier than one that occasionally went negative over 5 years.
• Consistency over peak. In the same category, prefer the fund whose rolling returns cluster tightly over one with a higher average but wild spread.
• The right window. Judge equity funds on 3- and 5-year rolling returns, not 1-year — one year is mostly noise.

See it for any fund

On each fund page, the rolling-returns chart shows exactly this — every rolling period, not a cherry-picked pair — and the FundScore already weights consistency, so a steady performer ranks above a lucky one. It's the difference between "what did this fund return once?" and "what would this fund have returned whenever you'd invested?"
