What nickname describes the 2000–2002 collapse of technology and internet shares?

The 2000–2002 collapse of technology and internet shares is known as the dot-com crash.

The crash followed the dot-com bubble, when investors placed exceptionally high valuations on internet and technology companies. Many firms had limited revenue, persistent losses, or business plans that depended on rapid future growth. The Nasdaq Composite reached 5,048.62 on 10 March 2000 before declining sharply.

As investors reassessed valuations and interest-rate conditions changed, many technology companies lost most of their market value. The Nasdaq eventually fell about 78 percent from its peak to its October 2002 low. Numerous internet start-ups failed, while stronger companies survived and later became important parts of the digital economy.

The dot-com crash is not the same as the 2008 financial crisis, which centered on credit, housing, and banking. Nor did every technology company fail: Amazon and other survivors continued operating through the downturn. The episode is a classic example of speculative valuation followed by a broad sector collapse.
