The collapse of technology-stock prices after the 2000 peak is called the dot-com crash.
During the late 1990s, investors poured money into internet companies, often valuing businesses on expected future growth rather than profits. The Nasdaq Composite, heavily weighted toward technology shares, reached a closing peak of 5,048.62 on March 10, 2000.
The bubble began to deflate soon afterward. Many companies lacked sustainable revenue, and rising skepticism led investors to sell internet and technology shares. The Nasdaq ultimately fell about 78% from its peak to its October 2002 low. The crash did not eliminate the internet economy: companies with durable business models survived or later expanded, while many speculative startups disappeared. It is often confused with the broader 2000–2002 bear market, which also affected nontechnology firms.
