Which index reached 5,048.62 at the peak of the dot-com bubble before the 2000–2002 crash?

The Nasdaq Composite reached 5,048.62 at the peak of the dot-com bubble before the 2000–2002 crash.

That record closing level was set on March 10, 2000. The index had risen rapidly as investors bought technology and internet companies, including many firms with limited revenue or no profits.

After the peak, expectations changed, interest rates rose, and investors became less willing to pay extreme prices for speculative businesses. The Nasdaq Composite fell sharply through 2000, 2001, and 2002, losing roughly 78% from its peak to its October 2002 low.

The Nasdaq Composite is a market-capitalization-weighted index containing thousands of Nasdaq-listed stocks, not simply a list of internet companies. Its collapse therefore reflected a broad technology-heavy market repricing, though the dot-com bust especially damaged internet start-ups.
