Which U.S. technology-heavy index fell 78% from its 2000 peak during the dot-com crash?

The Nasdaq Composite fell about 78% from its 2000 peak during the dot-com crash.

The index reached an intraday high of 5,132.52 on March 10, 2000, after years of enthusiasm for internet and technology companies. Many firms attracted investment despite limited profits, untested business models, or no established path to earnings. When expectations changed, technology shares fell rapidly.

The Nasdaq Composite eventually reached a low of 1,108.49 on October 9, 2002, representing a decline of roughly 78 percent from its peak. The fall damaged investors and businesses, while several highly valued internet companies failed or were acquired.

The crash is commonly linked with the bursting of the dot-com bubble, but the Nasdaq Composite is an index, not a company or exchange. The Nasdaq stock exchange also continued operating; the name of the index describes the broad group of listed shares it tracks.
