Which U.S. stock-market crash followed the peak of the dot-com bubble in March 2000?

The U.S. stock-market crash that followed the dot-com bubble's March 2000 peak was the dot-com crash.

The technology-heavy Nasdaq Composite reached a closing peak of 5,048.62 on March 10, 2000. Investors had driven internet and technology shares to extraordinary valuations, often based on expected future growth rather than profits. As earnings disappointed and interest-rate conditions changed, enthusiasm reversed.

The Nasdaq fell about 78% from its peak to its October 2002 low. Many internet companies failed, while others survived by changing their business models or securing more reliable revenue. The crash reduced investment in technology and contributed to a U.S. recession in the early 2000s.

The dot-com crash is not the same event as the 2008 housing and credit crisis. It centered on equity valuations and technology companies, although its effects spread into employment, business investment, and advertising. A few major firms that survived the crash later became among the world's most valuable companies.
