Which internet-focused U.S. stock index peaked on March 10, 2000, before the dot-com crash?

The Nasdaq Composite peaked on March 10, 2000, before the dot-com crash.

It closed at 5,048.62 that day, marking the high point of the late-1990s technology boom. The index contained many technology and internet companies, including businesses whose market values were based more on expected future growth than on current profits.

After the peak, investors became less willing to fund companies with weak earnings or unproven business models. The Nasdaq fell sharply through 2000, 2001, and 2002, losing roughly 78% from its peak to its October 2002 low.

The crash was not caused by the failure of one internet company. It followed a broad repricing of technology shares, rising concern about valuations, tighter monetary policy, and a shift in investor expectations. The Nasdaq later recovered and eventually exceeded its 2000 high.
