The nickname given to October 24, 1929, during the Wall Street Crash was “Black Thursday.”
On that day, heavy selling hit the New York Stock Exchange and the Dow Jones Industrial Average fell sharply in early trading. A group of leading bankers later met and attempted to restore confidence by purchasing large quantities of major shares. The market recovered some of its losses before closing, but the intervention did not end the broader decline.
Black Thursday was followed by a temporary rebound and then renewed selling. Black Monday occurred on October 28, and Black Tuesday followed on October 29. These labels describe key sessions in the same crash sequence rather than separate historical crashes.
The 1929 collapse reflected more than one day of panic. Speculative buying, margin debt, slowing economic conditions, and fragile confidence had created a market vulnerable to a sudden reversal. The crash helped undermine confidence, although the Great Depression resulted from a wider combination of economic and financial forces.
