What Is It?
The 1929 stock market crash was a major financial event where stock prices collapsed over several days in October 1929, marking the beginning of the Great Depression. The Dow Jones fell 25% in four days.
Origin
The 1920s saw rapid economic growth and stock market speculation. "Buying on margin" allowed investors to borrow heavily to buy stocks. The bubble burst on October 24, 1929 (Black Thursday), with panic selling continuing through Black Tuesday (October 29).
Why It Matters
The 1929 crash led to the Great Depression, the longest and most severe economic downturn in modern history. It prompted fundamental reforms including the creation of the SEC and modern securities regulation. Understanding the crash informs views on market bubbles and regulation.
