Which U.S. stock-market crash began after the 2000 dot-com bubble reached its peak?

The Dot-com crash began after the 2000 dot-com bubble reached its peak.

The Nasdaq Composite reached an intraday peak of 5,132.52 on March 10, 2000. Many internet and technology companies had attracted huge valuations despite limited profits, weak business models, or no earnings. When confidence changed, investors rapidly reassessed those companies.

The resulting decline became known as the dot-com crash. The Nasdaq fell steeply over the following years, while numerous internet startups failed, merged, or abandoned plans to go public. The downturn also affected established technology companies, although its effects varied widely across sectors.

The dot-com crash is different from the 2008 financial crisis. The earlier episode centered on technology-stock valuations and speculative expectations, whereas the later crisis centered on housing finance, credit markets, and banking-system stress. The Nasdaq eventually exceeded its 2000 peak many years later.
