Update — November 6, 2026, 4:06 p.m. Central: The Nasdaq Composite recovered 264.43 points, or 1.09%, to close Friday at 24,579.42, following Thursday’s sharp selloff. The S&P 500 gained 23.13 points, or 0.31%, to 7,376.86. The Dow Jones Industrial Average fell 237.33 points, or about 0.5%, to 51,285.73.

The rebound did not erase the week’s losses. The Nasdaq finished the week down 3.4%, while the S&P 500 lost 2.7% and the Dow declined 0.9%. These are Friday’s final closing figures. The November 5 account below is retained as dated background to the selloff and subsequent partial recovery.

Earlier Updates and Context — November 5, 2026:

Update — November 5, 4:22 p.m. Eastern: Final Associated Press figures showed the Nasdaq Composite fell 1,421.52 points, or 5.5%, to 24,315.00. The index finished 11.9% below its October 6 record, confirming correction territory. The S&P 500 dropped 334.89 points, or 4.4%, to 7,353.73, its worst day since the April 2025 tariff shock. The Dow Jones Industrial Average lost 1,833.06 points, or 3.4%, to 51,523.06, and the Russell 2000 fell 4.4% to 2,729.89. Reuters’ end-of-day review put the technology sector’s loss at 7.3% and the Philadelphia semiconductor index’s decline at 12%, its second-largest on record. These final figures supersede the preliminary closing prints below.

Update — November 5, 4:00 p.m. Eastern: The Nasdaq Composite closed in correction territory after its biggest one-day decline in 19 months, Reuters reported. Preliminary closing data showed the Nasdaq down 5.46% at 24,315.02, more than 10% below its October 6 record close. The S&P 500 fell 4.32% to 7,353.65 and the Dow Jones Industrial Average lost 1,842.69 points, or 3.45%, to 51,513.43. The closing figures supersede the intraday readings below; final exchange data can differ slightly from preliminary prints.

Update — November 5, 1:46 p.m. Eastern: The selloff accelerated, with the Nasdaq Composite down 5.2% and more than 10% below its October record, putting it in intraday correction territory. The S&P 500 was down 3.9% and the Dow Jones Industrial Average had lost 1,656 points, or 3.1%, according to the Associated Press. Nvidia fell 8.7%, Advanced Micro Devices dropped 15.5% and CoreWeave lost 12.5%. Every S&P 500 sector was lower, reversing the earlier market breadth described below. These remained intraday figures; a correction would be confirmed on a closing basis only if the Nasdaq finished at least 10% below its recent record.

U.S. stocks fell sharply late Thursday morning as another wave of selling in artificial-intelligence companies pushed the Nasdaq Composite toward correction territory and erased the broader market’s gains from the previous session.

The Nasdaq was down about 4.9%, the S&P 500 was off 3.2% and the Dow Jones Industrial Average had lost 1,079 points in the latest Associated Press update. The figures were intraday readings and could change before the closing bell.

Reuters reported earlier Thursday that the Nasdaq had fallen to about 24,712.60, more than 10% below its record closing high of 27,599.89 set October 6. A decline of at least 10% from a recent high is commonly described as a market correction. The index would need to finish at that level to confirm the move on a closing basis.

The heaviest pressure came from companies linked to the expansion of AI data centers. Nvidia was down 6.3%, Advanced Micro Devices fell 13.1% and CoreWeave lost 10%, according to the AP. Investors have been reassessing whether large spending commitments for chips, data centers and related infrastructure will produce returns quickly enough to justify current valuations.

Tuesday’s U.S. midterm elections added a policy concern. Democrats’ victories in Congress raised expectations of closer scrutiny or possible pauses for some data-center projects, although the scope and timing of any future action remained uncertain.

The selloff was not uniform. A slight majority of stocks in the S&P 500 were higher, the AP reported, but declines in the largest technology companies outweighed those gains because of their heavy influence on the index. AppLovin and Tapestry rose after reporting stronger-than-expected results.

Other markets were mixed. Brent crude gained 2.5% to $96.95 a barrel after a nearly 9% drop Wednesday, while the 10-year Treasury yield eased to 4.86%.

Thursday’s decline followed a major post-election rally Wednesday, when the Dow rose more than 1,500 points. The reversal underscores the market’s sensitivity to AI investment expectations and prospective policy changes.
