Which 1929 U.S. stock-market crash began with Black Thursday and culminated in Black Tuesday?

The 1929 U.S. stock-market crash that included Black Thursday and Black Tuesday was the Wall Street Crash of 1929.

After years of rising prices and widespread buying on margin, the market became vulnerable to a loss of confidence. Heavy selling began on October 24, 1929, known as Black Thursday, and intensified on October 28 and 29.

Black Tuesday, October 29, saw exceptionally heavy trading and large price declines. The crash did not single-handedly cause the Great Depression, but it damaged wealth, confidence, investment, and the banking system.

The crash is often described as lasting only two days, but the broader bear market continued for years. The Dow Jones Industrial Average eventually reached its low in July 1932, after the economic depression had deepened.
