Which technology-sector bubble burst in 2000, helping cause a major stock-market crash?

The dot-com bubble burst in 2000, helping cause a major stock-market crash in technology shares. The bubble involved intense speculation in internet-related companies, many of which had little revenue or no profits.

The Nasdaq Composite reached an intraday peak of 5,132.52 on March 10, 2000. As investor expectations changed, technology shares fell sharply, and numerous internet companies failed or were acquired at much lower valuations.

The dot-com crash is distinct from the 2008 financial crisis, which centered heavily on housing, mortgages, and banking. Some large technology companies survived and later became highly valuable, but the collapse demonstrated that a compelling new technology does not guarantee that every related stock is fairly priced.
