Which 1990s technology-heavy index fell about 78% after the dot-com bubble burst?

The technology-heavy Nasdaq Composite fell about 78 percent after the dot-com bubble burst.

The Nasdaq Composite rose from about 751 in 1994 to an intraday peak of 5,132.52 on 10 March 2000. Investors had bid up internet and technology companies, including many businesses with little revenue or no profits. When expectations changed, technology shares began a prolonged collapse.

The index reached a bear-market low of 1,108.49 on 9 October 2002, representing an approximately 78 percent decline from its 2000 peak. The bursting bubble affected venture capital, telecommunications, advertising, and employment as many internet companies failed or sharply reduced operations.

The Nasdaq Composite is an index, not a company or a stock exchange. It includes many companies listed on the Nasdaq market, with a strong technology weighting. The broader S&P 500 also declined during the episode, but its fall was substantially smaller than the Nasdaq’s.
