On which date did the 1929 Wall Street Crash begin with the day called Black Thursday?

The 1929 Wall Street Crash began with Black Thursday on October 24, 1929. Heavy selling on the New York Stock Exchange caused prices and investor confidence to plunge.

The market had risen dramatically during the 1920s, especially in popular industrial shares. Many investors bought stocks on margin, borrowing money to increase their exposure. When prices weakened, forced selling magnified the decline. On Black Thursday, roughly 12.9 million shares changed hands, a record at the time.

A group of major bankers attempted to stabilize prices by buying selected blue-chip stocks, and the market temporarily recovered. That relief did not last. Panic returned on Black Monday, October 28, followed by Black Tuesday, October 29, when about 16.4 million shares were traded.

The crash did not by itself cause every feature of the Great Depression, but it badly damaged wealth, confidence, and financial institutions. The market’s later decline continued for years, with the Dow eventually reaching its low in July 1932.
