What was the nickname of the stock market crash on October 29, 1929?

The stock market crash on October 29, 1929, was nicknamed Black Tuesday.

Black Tuesday marked the climax of the panic on the New York Stock Exchange. Investors rushed to sell shares, often because falling prices triggered margin calls on borrowed-money purchases. The Dow Jones Industrial Average dropped 30.57 points, or about 11.7 percent, that day.

Approximately 16 million shares traded, overwhelming the exchange’s reporting systems and leaving ticker tapes far behind current prices. The market lost about $14 billion in stock value during the day, though the decline was part of a broader collapse rather than an isolated event.

A common mix-up is Black Thursday, October 24, when the first major wave of panic struck. Black Monday refers to October 28, 1929, while “Black Monday” is also the established name for the separate global crash of October 19, 1987.
