Calculation:

ln(close ÷ previous close) for each trading day in the last 365 days; sample standard deviation of the returns × √252; minimum of 200 trading days. A return that crosses the record date of a recorded split, reverse split or stock bonus is discarded, because an unadjusted price around the event is not market movement. Returns discarded because of a corporate event: 0.

Limitation:

Describes how much daily closes already moved; it does not indicate price direction nor guarantee it will repeat. It changes with the window and the annualization factor. Corporate events for this asset class are not yet recorded by InvestimentoTech; a split or reverse split in the period may inflate the number.

Where it came from, when we collected it and what the number doesn't say. It's the data's origin, never a judgment on the asset.
