What happened to the Nasdaq, S&P 500 and Dow?
On November 5, the Nasdaq Composite fell 5.52% to about 24,315, the S&P 500 declined 4.36% to 7,353.73 and the Dow Jones Industrial Average lost 3.44% to 51,523, according to Reuters' closing-market account. Associated Press separately confirmed the broad selloff and its concentration in AI-linked shares.
| Index | Daily change | Reported close |
|---|---|---|
| Nasdaq Composite | −5.52% | About 24,315 |
| S&P 500 | −4.36% | 7,353.73 |
| Dow Jones Industrial Average | −3.44% | 51,523 |
The Nasdaq decline was its largest daily percentage loss in roughly 19 months. The benchmark also fell more than 10% from its October 6 closing record, meeting the conventional definition of a market correction. A correction describes a price decline; it does not automatically mean an economic recession or guarantee further losses.
Why did Nvidia, AMD and AI infrastructure stocks fall?
Chipmakers and companies supplying data centers were hit particularly hard. AP reported Nvidia down 9.3%, AMD down 17.3% and power-equipment supplier GE Vernova down 7.5% on Thursday. Reuters reported the Philadelphia Semiconductor Index falling more than 12%.
Investors were weighing multiple overlapping risks rather than one confirmed new law. Democratic gains in the US midterm elections raised expectations of greater scrutiny of data-center permitting, electricity and water use, while expensive borrowing and uncertain returns on AI infrastructure spending already concerned investors. Reuters described how worries about future restrictions and financing affected semiconductor and data-center valuations. Expectations about policy are not the same as enacted restrictions.
Did stocks rebound on Friday, November 6?
Yes, but only partly. The Nasdaq Composite gained approximately 1.09% on Friday to around 24,579, according to the Guardian's November 6 market coverage. Investor's Business Daily reported Nvidia rebounding 2.8% and AMD roughly 11% on Friday. These gains were measured from already depressed prices; they did not restore the previous week's levels.
The rebound is also not evidence that concerns over data-center spending, permitting or valuations have disappeared. Friday's jobs data and interest-rate expectations added another variable to an already volatile market.
What does this mean for US investors and retirement savers?
Broad-market funds can still have meaningful exposure to the largest technology companies. Investors comparing daily headlines should check their actual fund holdings, concentration and investment horizon rather than assume that an index correction means every portfolio has fallen by the same amount. A sharp drop followed by a rally is not, by itself, a reliable buy or sell signal.
Three questions matter next: whether companies demonstrate cash returns from AI infrastructure, whether financing remains available at sustainable costs, and whether policymakers introduce actual restrictions affecting new data-center projects. Those are forward-looking uncertainties, not settled outcomes.
For context, read our November US consumer-sentiment analysis and Berkshire Hathaway Q3 earnings explainer. These cover different economic indicators and should not be confused with direct causes of Thursday's market decline.
