What name is given to the 2000–2002 collapse in technology-share valuations after the dot-com boom?

The 2000–2002 collapse in technology-share valuations was the dot-com bubble burst.

In the late 1990s, investors bid up companies associated with the internet and new digital technologies. Many businesses had little revenue or no profits, yet their share prices were justified by expectations of rapid future growth. The Nasdaq Composite became the clearest market measure of this enthusiasm.

The Nasdaq reached 5,048.62 on March 10, 2000, then began a prolonged decline. Higher interest rates, disappointing business results, and rising skepticism about internet-company valuations weakened the market. Numerous startups failed when they could no longer raise capital.

The bubble’s collapse is often called the dot-com crash or dot-com bust. It differed from the 2008 crisis because its central excess involved technology-company valuations and venture financing rather than a worldwide housing-credit breakdown.
