What you're looking at
Every trading day since 1995 we count the US stocks that were trading that day, including the ones that later went bankrupt or were taken over. Leaving those out would make every crash look milder than it was.
A stock counts when it is a real, traded company that day: a share price of $5 or more, at least $1 million traded a day, and a year of history.
The normal day is the median since 1995: half of all days were above it, half below. The record is the highest day.
The index describes the market; it does not forecast it. A high reading has come before rebounds and before further falls.
