The 2000 dot-com crash began after which US technology index peaked on March 10, 2000?

The Nasdaq Composite peaked on March 10, 2000, just before the dot-com crash intensified.

The index had become a widely watched measure of technology and internet enthusiasm because it contained many software, telecommunications, and internet companies. From the mid-1990s, investors poured money into businesses with rapidly growing website traffic and ambitious plans, even when those companies had little revenue or no profits.

After the March 2000 peak, technology shares declined sharply. Higher interest-rate expectations, disappointing business results, and growing skepticism about extreme valuations helped reverse the speculative boom. The Nasdaq Composite eventually fell about 78% from its 2000 peak to its October 2002 low.

The crash did not mean that the internet lacked long-term economic value. Instead, it showed that a useful technology can still be surrounded by unsustainable valuations. The Nasdaq is an index, not a single company, and its peak is distinct from the later recovery record.
