Which crash began when the NASDAQ Composite peaked at 5,048.62 in March 2000?

The crash that began after the NASDAQ Composite peaked at 5,048.62 in March 2000 was the dot-com bubble burst.

The NASDAQ reached its closing peak on March 10, 2000, as investors had driven technology and internet-company valuations to extraordinary levels. Many newly listed companies had little revenue, no profits, or business plans dependent on continued access to venture capital. Rising interest rates and disappointing earnings helped change market sentiment.

The index then fell sharply, losing about 78% of its value from the peak to its October 2002 low. Several prominent internet companies failed, while established technology firms also saw enormous declines in their share prices. The crash damaged investment and employment in the technology sector.

The collapse did not mean that the internet itself lacked economic value. Companies such as Amazon and eBay survived and later expanded, while the crash mainly exposed unrealistic valuations and unsustainable financing. The event is also called the dot-com crash or technology bubble burst.
