Which technology-focused U.S. stock index fell about 78% after the dot-com bubble peaked?

The NASDAQ Composite fell about 78% after the dot-com bubble peaked.

The index reached an intraday high of 5,132.52 on 10 March 2000, reflecting intense enthusiasm for internet and technology companies. Many businesses had little revenue or no profits, but investors expected rapid growth and frequently valued companies using optimistic assumptions.

After the bubble burst, technology shares fell sharply. The NASDAQ Composite eventually reached a bear-market low of 1,108.49 on 10 October 2002, roughly 78 percent below its peak. The decline damaged both established technology firms and newly listed internet companies.

The dot-com crash is not identical to the 2008 financial crisis. It centred on technology-stock valuations and business expectations, whereas 2008 involved housing finance, mortgage securities, banks, and a broader credit-system breakdown.
