What was the Dow Jones Industrial Average's peak date immediately before the 1929 crash?

The Dow Jones Industrial Average reached its pre-crash peak on September 3, 1929.

The index closed at about 381.17 on that date, marking the high point of the speculative boom that preceded the Wall Street Crash. Share prices had risen rapidly during the 1920s, and many investors bought stocks with borrowed money through margin accounts.

The market then became increasingly unstable. Black Thursday arrived on October 24, followed by severe selling on October 28 and Black Tuesday on October 29. Although the crash unfolded over several sessions, the September peak provides a clear benchmark for measuring the subsequent decline.

The Dow did not return to its September 1929 closing high until November 1954. That long recovery period is one reason the crash remains central to financial history. It is also important to distinguish the market's peak date from the start of the broader Great Depression, which involved many economic causes and developed over time.
