The Nasdaq Composite’s lowest closing value during the dot-com crash was 1,114.11 on October 9, 2002.
The technology-heavy index had closed at 5,048.62 on March 10, 2000, at the height of the dot-com bubble. Over the following two and a half years, investors reassessed internet companies whose valuations often depended on rapid future growth rather than profits. Many businesses failed when financing disappeared.
The October 2002 close represented a decline of roughly 78% from the 2000 peak. The crash affected technology shares especially severely, although it also damaged venture capital, telecommunications, and other parts of the broader economy.
The 2002 low is different from the Nasdaq’s March 2000 peak, which is frequently cited in crash questions. The index eventually recovered its former closing high in March 2015, nearly 15 years after the bubble peak.
