Price checkExperimental
SwingsVery bumpy

Swung more than 88% of stocks we rank over the past year (79% a year).

How this is worked out

What it measures: day-to-day price moves over the past year, as a yearly figure, ranked against every stock we cover. Very calm under 20% a year, Calm 20 to 30%, Average 30 to 40%, Bumpy 40 to 55%, Very bumpy above that.

What we found: across about 13,500 stocks in 34 markets (2002 to 2025), past swings were a good guide to the next year's, and bumpier stocks fell further. How much further changed too much between eras to put a number on it.

Calm is not safe: a calm stock can still slide steadily.

Rules fixed before any data was fetched. Describes the chart, not a recommendation.
