Nasdaq Took More Than a Decade to Recover From 78% Dot-Com Drop

The Nasdaq Composite needed more than a decade to recover its dot-com-era peak after losing about 78%, while other U.S. market downturns delivered their sharpest damage in a single day. The episodes show how selloffs can differ in both speed and duration.

The Nasdaq fell from its March 2000 high to an October 2002 low during the collapse of the dot-com bubble. It did not regain its previous peak for more than 10 years. The Philadelphia Semiconductor Index, by contrast, recorded its largest one-session drop on March 16, 2020, when it fell 15.9%.

The 1929 crash combined steep daily losses with a prolonged decline. The Dow Jones Industrial Average dropped 12.82% on Oct. 28 and another 11.73% the next day. By July 1932, it had fallen about 89% from its peak.

On Oct. 19, 1987, the Dow plunged about 22.6%, its biggest one-day percentage decline. Selling linked to portfolio insurance and computerized trading intensified the drop. The episode was followed by changes to trading safeguards, including circuit breakers.

During the 2008 financial crisis, the Dow lost 6.98% on Sept. 29 after the U.S. House rejected a financial rescue plan. The S&P 500 fell about 8.8%, while the Nasdaq declined about 9.1%. The Dow dropped another 7.87% on Oct. 15. Across the broader downturn, the S&P 500 fell about 57% from its October 2007 high to its March 2009 low.

The May 6, 2010, flash crash was brief: The Dow plunged nearly 1,000 points intraday, then recovered most of that loss and finished down about 3.2%.

The pandemic-driven selloff brought another severe session on March 16, 2020. The Dow fell 12.93%, the S&P 500 lost 11.98% and the Nasdaq dropped 12.32% that day. The semiconductor index’s 15.9% decline was its largest on record.

In 2022, losses accumulated over months. As high inflation and Federal Reserve rate increases weighed on markets, the S&P 500 fell about one-quarter from its January high to its October low. The Nasdaq’s decline was larger. These episodes ranged from a rapid reversal within one session to market losses that took years to recover.
