Which U.S. technology-stock bubble burst in 2000, leading to a major market decline?

The U.S. technology-stock bubble that burst in 2000 was the dot-com bubble.

During the late 1990s, investors poured money into internet businesses, many of which had little revenue or no profits. The Nasdaq Composite rose dramatically as traders speculated that online commerce would transform business. The bubble began to deflate in March 2000, and technology shares continued falling for roughly two years.

The Nasdaq reached a closing peak of 5,048.62 on March 10, 2000, then lost about 78% of its value by October 2002. The crash did not mean that the internet was unimportant; instead, it showed that promising technology could still be purchased at unsustainable prices. A common mix-up is calling every technology downturn the dot-com crash; the term specifically refers to the collapse of the late-1990s internet-stock boom.
