What was the name of the U.S. technology-heavy index that plunged during the dot-com crash?

The Nasdaq Composite was the U.S. technology-heavy index that plunged during the dot-com crash.

The index had risen dramatically during the dot-com bubble, as investors poured money into internet and technology companies. Many firms had limited revenue, large losses, or business plans based mainly on rapid future growth. The Nasdaq Composite reached a closing peak of 5,048.62 on March 10, 2000.

After the bubble burst, technology shares fell for roughly two years. The Nasdaq lost about 78% from its peak to its October 2002 low. Numerous internet companies failed, while survivors faced layoffs, falling valuations, and pressure to demonstrate sustainable profits.

The dot-com crash was not a total collapse of technology as an industry. Companies with durable products, infrastructure, or strong finances eventually recovered and helped drive later market growth. The common error is equating the bubble’s failure with the disappearance of the internet economy.
