Which technology-heavy U.S. stock index peaked at 5,048.62 during the dot-com crash era?

The Nasdaq Composite peaked at 5,048.62 during the dot-com bubble before the technology-stock crash began.

The index reached that closing high on March 10, 2000, after years of enthusiasm for internet companies and other technology businesses. Many firms attracted enormous valuations despite having little revenue or no profits, while investors expected rapid growth from the new commercial internet.

After the peak, the Nasdaq Composite fell dramatically as technology shares were repriced. The decline became the defining market movement of the dot-com crash, although the broader economic consequences were less severe than those of the 1929 or 2008 crises.

The Nasdaq Composite is not the same as the Nasdaq-100. The Composite includes thousands of Nasdaq-listed stocks, whereas the Nasdaq-100 tracks 100 large non-financial companies listed on that exchange. That distinction makes the Composite the specific index associated with the 5,048.62 peak.
