The 2000–2002 crash in technology shares after the dot-com boom is called the dot-com crash.
During the late 1990s, investors poured money into internet companies, often valuing businesses on anticipated growth rather than profits. The Nasdaq Composite rose dramatically and reached a closing peak of 5,048.62 on March 10, 2000. When confidence weakened, many newly listed companies lost most of their value or failed.
The Nasdaq continued falling until October 2002, when it had lost roughly 78% from its peak. The crash is sometimes described as the bursting of the dot-com bubble, while the broader period of declining technology shares is called the dot-com crash. It was not the same event as the 2008 financial crisis, although the two downturns affected investors and the wider economy in different ways.
