Which technology-stock bubble burst worldwide between 2000 and 2002?

The technology-stock bubble that burst worldwide between 2000 and 2002 was the dot-com bubble.

Internet companies attracted extraordinary investment during the late 1990s, even when many had little revenue or no profits. Investors often valued firms according to website traffic, projected growth, or the promise of a future online economy rather than established business performance.

The Nasdaq Composite reached a record close of 5,048.62 on March 10, 2000. It then fell sharply as high-profile technology companies missed expectations and confidence weakened. The downturn spread beyond newly created internet firms to many established technology businesses.

The dot-com bubble is sometimes confused with the broader 2000–2002 bear market, but the bubble describes the speculative boom and its collapse. It also differs from the 2008 housing and credit crisis, which centered on mortgages and the banking system.
