What nickname describes the 13 October 1989 U.S. market plunge triggered by the collapse of a leveraged buyout?

The U.S. market plunge on 13 October 1989 is known as the Friday the 13th mini-crash.

The sell-off came after the proposed $6.75 billion leveraged buyout of United Airlines collapsed. Investors feared that the failure signaled trouble for the market for highly leveraged takeovers and junk bonds. The Dow Jones Industrial Average fell 190.58 points, or about 6.9 percent, in a single session.

Because it was much smaller and shorter than the October 1987 crash, journalists called it a “mini-crash.” The event occurred on a Friday that fell on the 13th, supplying the memorable nickname. It is sometimes mistakenly grouped with Black Monday, but Black Monday refers to 19 October 1987, when markets worldwide suffered a far larger one-day percentage collapse.
