The Dow Jones Industrial Average reached its post-crash low on July 8, 1932.
On that date, the Dow closed at 41.22, down from its 1929 peak of 381.17. The date is easy to confuse with Black Tuesday, October 29, 1929, when the initial crash became especially dramatic. The market's deepest point arrived nearly three years later, after continued economic contraction and banking distress.
The 1932 low occurred during the Great Depression, when unemployment, industrial output, prices, and international trade had all fallen sharply. The Dow began a powerful recovery after the summer of 1932, but it still did not return to its 1929 closing high until 1954. The crash therefore describes a prolonged market collapse, not only the famous trading days of October 1929.
