What was the name of the 1989 stock-market crash in which the Dow Jones Industrial Average fell 6.9% on October 13?

The 1989 stock-market crash in which the Dow Jones Industrial Average fell 6.9% on October 13 was the Friday the 13th mini-crash.

The event occurred on Friday, October 13, 1989, after the proposed leveraged buyout of United Airlines collapsed. The Dow Jones Industrial Average dropped 190.58 points, or 6.91 percent, in one of the largest one-day percentage declines then recorded.

The decline was amplified by computerized trading and portfolio-insurance strategies, which could generate automatic selling as prices moved lower. Investors also worried about the fragility created by highly leveraged corporate transactions.

The episode was much smaller and shorter-lived than the October 1987 crash. It is also sometimes called the mini-crash of 1989, while its more memorable name refers to the calendar date. The market recovered relatively quickly compared with the prolonged declines after 1929 or 2000.
