The U.S. technology exchange especially associated with the dot-com bubble was Nasdaq.
Nasdaq became the main public-market home for many internet and technology companies during the 1990s. Investors often bid up shares based on expected future growth rather than current profits. New companies could attract enormous valuations even when they had limited revenue, large losses, or untested business models.
The Nasdaq Composite reached a closing peak of 5,048.62 on March 10, 2000. It then declined sharply as investors questioned whether technology companies could justify their prices. The collapse destroyed trillions of dollars in market value and contributed to a recession in the United States.
The bubble’s bursting did not mean every internet company failed. Amazon survived and later became highly valuable, while companies such as Pets.com disappeared. Nasdaq is also not itself a company in this context: it is the exchange and the name used for several market indexes, including the Nasdaq Composite.
