What date marked the Wall Street peak immediately before the 1929 stock-market crash?

The Wall Street market peak immediately before the 1929 stock-market crash occurred on September 3, 1929.

The Dow Jones Industrial Average reached a closing high of 381.17 on that date. The peak followed several years of rising share prices and widespread public interest in stock speculation. Many buyers purchased shares with borrowed money, a practice that magnified both gains and losses.

The market then became unstable. September and early October brought declines, although prices temporarily recovered. The most famous panic days came later: Black Thursday on October 24, Black Monday on October 28, and Black Tuesday on October 29. These sessions intensified the collapse in confidence and selling pressure.

The crash itself was not the sole cause of the Great Depression. Bank failures, reduced consumer demand, industrial weakness, debt, and policy mistakes also contributed. The market’s ultimate low came in 1932, when the Dow stood far below its 1929 peak.
