Which technology-focused U.S. stock index fell sharply after the dot-com bubble burst in 2000?

The Nasdaq Composite fell sharply after the dot-com bubble burst in 2000.

The index, heavily weighted toward technology and internet companies, reached an intraday peak of 5,132.52 on 10 March 2000. Many businesses had attracted enormous valuations despite limited revenue, continuing losses, or untested business models. As investors began demanding stronger earnings evidence, technology shares fell rapidly.

The Nasdaq Composite ultimately lost about 78% of its value from its 2000 peak to its October 2002 low. The crash damaged venture capital, advertising, telecommunications, and technology employment, while companies with durable products and profits survived or later recovered.

The Dow Jones Industrial Average also declined during this period, but it was not the index most closely associated with the dot-com collapse. The 2008 crash had a different central cause, involving housing finance, banking, and structured credit rather than internet-stock valuations.
