How it is measured
The move is the close-to-close return; its size is that return divided by the standard deviation of Dow Jones's previous 20 daily returns. A quake is 3σ or more. This record was made the night after the day finished trading and has not been changed since. The live chart is on Dow Jones's page; the last few months of every market's daily moves are on the volatility terrain, and every quake on record is in the quake archive.
