Which technology-heavy index became the main symbol of the dot-com crash that began in 2000?

The Nasdaq Composite became the main symbol of the dot-com crash that began in 2000.

The index had risen rapidly during the late-1990s technology boom because it contained many internet, software, telecommunications, and other growth companies. It reached a peak of 5,048.62 on March 10, 2000, before falling dramatically as investors questioned whether many newly listed businesses could ever become profitable.

The collapse was not limited to companies with weak business models. Established technology firms also suffered as valuations contracted and investment capital became harder to obtain. The Nasdaq ultimately lost roughly 78% of its value from its 2000 peak to its 2002 low.

The Dow and S&P 500 also declined, but the Nasdaq is most closely associated with the episode because of its concentration in technology and internet shares. The crash helped establish the phrase “dot-com bubble” in popular financial history.
