What was the 1989 U.S. market crash on 13 October commonly called?

The 1989 U.S. market crash on 13 October was commonly called the Friday the 13th mini-crash.

The Dow Jones Industrial Average fell 190.58 points, or 6.91%, in a single session. The decline was linked partly to the collapse of a proposed leveraged buyout of United Airlines, which unsettled investors and contributed to broader selling.

The episode was much smaller than Black Monday in 1987, so the word “mini-crash” became part of its usual name. It also occurred on a Friday that fell on the 13th, giving the event its memorable calendar-based label.

This crash is sometimes confused with the 1987 Black Monday or with later technology-related market declines. The Friday the 13th event was a brief U.S. equity shock, not the start of the long dot-com crash or a worldwide banking crisis.
