Wall Street Decided the AI Panic Was Overdone by Monday Lunch, and the Only Chipmaker That Couldn't Rebound Did It to Itself

EVENING MARKET SCRIPT: Monday, November 9, 2026

Good evening.

Wall Street spent last week worrying that Democrats’ midterm sweep would bring new rules for data centers, energy use and the AI boom. On Monday, investors looked at those worries again, decided the selloff had gone too far, and bought technology shares back.

Most of them, anyway.

The Dow Jones Industrial Average surged 1,104.02 points. The S&P 500 posted its biggest daily percentage gain since April 8. The Nasdaq had its strongest daily advance since July 30. Chipmakers bounced sharply after a bruising week.

And Nvidia, the world’s second-most valuable company, fell 4.2%.

The difference was not a new chip, a fresh earnings warning or a sudden collapse in data-center demand. Nvidia shares were hit by a controversy involving CEO Jensen Huang, who told employees he had an affair with a businesswoman whom U.S. intelligence agencies allege is a Chinese spy. Nvidia’s board opened an independent investigation into the allegations.

So, by Monday’s close, the market had delivered two messages at once: broad fears about AI regulation looked overdone to many investors, while Nvidia had acquired a company-specific problem that did not require a congressional hearing to get attention.

The verdict, in short: Wall Street relaxed about the political risk. It did not relax about Nvidia’s CEO problem.

WHAT YOU’LL LEARN: What drove the rebound, why Nvidia diverged from the chip rally, and what investors will be watching as inflation data, earnings and a still-unsettled Federal Reserve outlook arrive this week.

A Big Rebound. Not a Clean Bill of Health.

Start with the headline numbers. All three major U.S. stock indexes finished sharply higher. The Dow rose 2.15% to 52,389.75. The S&P 500 added 2.35% to 7,549.94. The Nasdaq Composite gained 2.74% to 25,253.14.

For the S&P 500, that was the biggest daily percentage gain since April 8. For the Nasdaq, it was the biggest daily advance since July 30. The Russell 2000, a small-cap index, rose 3.15% to 2,840.81.

The Dow also moved back above its Election Day closing level. The S&P 500 and Nasdaq remained slightly below theirs. That distinction matters: Monday was a powerful recovery session, but not every index had fully erased the ground lost since Election Day.

The breadth was impressive. All 11 S&P 500 sectors rose. Industrials and consumer discretionary shares each gained more than 3%. That is more than a technology-only bounce. It points to buying across a wider range of the market.

But a green screen does not settle every question that drove last week’s volatility. It does not tell investors what Congress will propose, how the Federal Reserve will respond to inflation, or whether the next round of AI spending will meet the profit expectations built into current valuations.

A sharp rebound says investors were willing to buy at Monday’s prices. It does not say the risks have vanished. The market, as ever, is confident right up until its next reason not to be.

Oil Helped Make the Case for Risk

The clearest support for the rally came from a market outside the technology sector: oil.

U.S. West Texas Intermediate crude fell 4.38% to settle at $86.85 a barrel. Brent, the international benchmark, slid 5.85% to $92.57. Lower oil prices helped cool concerns that energy costs could feed inflation and complicate the Federal Reserve’s next move.

Reuters reported that the drop came as President Donald Trump downplayed the likelihood of renewed strikes on Iran. That was the news framing around the market move. The timing is relevant; it is not proof that one statement alone caused oil prices to fall. Oil prices move on a mix of expectations, supply concerns and geopolitical developments. Markets can be dramatic about each of those, often before the facts have finished arriving.

Still, the direction mattered to investors. When crude fell, inflation worries eased enough to support a broad advance in stocks. The day’s rally was not just a referendum on whether AI regulation might slow the data-center buildout. It was also a bet that pressure from energy prices might be less severe than feared.

That relief has limits. WTI settled at $86.85, not at a level that removes oil from the inflation conversation. And lower crude on Monday does not answer what Tuesday’s consumer-price data or Friday’s producer-price report will show.

For now, oil provided Wall Street with a welcome tailwind. It did not write the rest of the week’s forecast.

Last Week’s AI Panic Met Its First Serious Buyer

The previous week was ugly for technology shares. The S&P 500 had its worst week since April 2025. The selloff followed the Democrats’ midterm sweep, which fed investor concerns that new regulation around data centers, energy use and development costs could weigh on the AI trade.

Those concerns were about the conditions for building and powering data centers, the infrastructure behind the rapid expansion of AI computing, not simply about whether people would use AI tools. A tougher regulatory environment could increase costs, delay projects or make some planned investments harder to execute.

That is a legitimate risk. It is also not the same thing as saying the AI business has stopped growing. Markets tend to collapse those two ideas into one very nervous trade, then remember they are different once prices have fallen far enough.

On Monday, some major Wall Street firms made that argument explicitly. Morgan Stanley and UBS called last week’s rout in AI stocks overdone. Both pointed to the risk that political fears had pushed prices too far down, while arguing that the threat of extreme restrictions on data-center development was limited.

Oppenheimer strategist John Stoltzfus also argued that the market could rebound if the fundamentals supporting economic growth, revenue and profit remained intact. That is a conditional case, not a guarantee. If the fundamentals deteriorate, a bargain can turn out to be merely a lower price on a weaker business.

There was a counterweight to the buy-the-dip mood. Citi tactically downgraded U.S., global and European technology shares to Neutral, citing positioning and sentiment. The bank’s position was not that the long-term AI story had disappeared. It was that investor positioning and the mood around the trade could remain unstable, and Citi wanted cleaner conditions before becoming more bullish again.

That is the useful distinction in Monday’s debate:

1. The AI investment case may remain intact. Demand for computing and data-center infrastructure has not been shown to disappear merely because investors fear regulation.
2. The path of that investment can still change. Rules affecting construction, energy consumption or project costs could delay or reshape spending.
3. Valuations and sentiment can overshoot in both directions. Last week’s selloff may have been too severe. Monday’s rebound does not prove the market has finished reacting.

In other words, “the AI panic was overdone” is a market judgment about the scale of the selloff. It is not a promise that regulation will be irrelevant, that every planned data center will be built on schedule, or that every AI stock is suddenly a bargain.

Wall Street’s mood changed quickly. The underlying debate did not.

The Exception: Nvidia’s Problem Was Not an AI Regulation Problem

Nvidia was the lone decliner in the Philadelphia Semiconductor Index on Monday. The index itself jumped 6.9%, recovering after falling more than 12% last week. Broadcom climbed 8.8%. Advanced Micro Devices surged 13.3%.

Nvidia, by contrast, dropped 4.2% to about $178.51 and closed at its lowest level since April 7. The company remains the world’s second-most valuable, but its stock was moving to a separate story.

Nvidia’s board opened an independent investigation into CEO Jensen Huang’s relationship with businesswoman Alice Huang, whom intelligence agencies allege is a Chinese spy. Those are allegations, not established findings. The board’s investigation is ongoing, and the claims should be described that way.

In an email to staff on Sunday, Huang said he had an affair with the woman and that the board had opened an independent investigation into the spying allegations. An Nvidia spokesperson said Huang was committed to continuing as CEO without interruption.

That leaves investors with two issues to watch, and they are not interchangeable. One concerns the allegations and what an independent review finds. The other concerns governance and leadership: how the board handles the investigation, what information becomes public, and whether the controversy distracts the company or changes its leadership outlook.

There is no need to invent a business impact before one is known. There is also no need to pretend that a controversy involving a company’s chief executive is irrelevant simply because the company sells critical AI hardware.

Nvidia’s decline was striking precisely because the rest of the chip group was recovering. For the sector, Monday looked like a reversal of last week’s panic. For Nvidia, the market had another question to price.

The irony was fairly efficient: investors who had spent the week worrying that government rules could complicate the AI trade ended Monday buying chip shares, except for the one whose immediate headline involved its own board, its CEO and his email to employees.

The Interest-Rate Backdrop Is Still There

The drop in oil and the rebound in technology stocks did not erase the pressure on the Federal Reserve.

Expectations for a rate hike at the Fed’s December meeting remained above 80%, according to CME FedWatch, after October’s strong jobs report. That is a market-implied probability, not a decision by the Federal Reserve. The distinction is worth keeping: traders’ expectations can move, and the Fed still has to make its own assessment of the data.

Richmond Fed President Tom Barkin said the central bank should move “with care” as it considers its response to inflation. “With care” does not promise any particular rate decision. It does underline that policymakers are weighing inflation risks rather than treating one day’s lower oil prices as a complete answer.

This week’s inflation releases will give markets fresh numbers to parse. The Consumer Price Index for October is due Tuesday. The Producer Price Index is due Friday. CPI tracks prices paid by consumers; PPI measures prices received by producers and can offer clues about costs moving through businesses and supply chains.

Investors will be looking at both reports for evidence about inflation’s direction, and, by extension, how much room the Fed has to change policy. If inflation remains stubborn, the market may have to revisit its optimism about rates. If the data are softer, the Monday rally could find another reason to keep going.

For now, the market has conflicting inputs: a strong jobs report that has kept rate-hike expectations elevated, falling oil that offers some inflation relief, and a Fed official urging caution. That is not a settled outlook. It is a calendar full of catalysts.

This Week’s Checklist: Inflation, Earnings and Follow-Through

The immediate schedule is straightforward. The interpretation will not be.

Tuesday: October CPI. This is the first major test after Monday’s relief rally. Investors will watch whether consumer inflation supports the view that price pressures are easing, or suggests the Fed may need to stay more aggressive.

Friday: October PPI. Producer prices will provide another inflation reading, this time from the business side. A hotter-than-expected report could revive concern about costs working their way toward consumers.

Company earnings: CoreWeave, Cisco and Applied Materials. All three are reporting this week. For investors trying to distinguish AI enthusiasm from actual business performance, those results and outlooks will matter. The market will be looking for evidence about demand, spending and the economics of the infrastructure supporting the AI buildout.

There is also a technical question: can the rebound hold? Monday delivered a powerful move, but a single session does not establish a new trend. Citi’s caution about positioning and sentiment, and the broader market’s sensitivity to news, remain relevant. Investors may be buying because last week’s losses looked excessive. They may also be waiting to see whether Tuesday’s data give them a reason to keep buying.

If you are following the market, keep the checklist simple:

• Separate sector recovery from individual-company risk. The semiconductor index jumped. Nvidia still fell.
• Watch the inflation data, not just the oil quote. Lower crude helped on Monday; CPI and PPI will add more information.
• Read earnings outlooks for execution, not just AI buzzwords. Spending plans matter. So do costs, timelines and returns.
• Treat probabilities as expectations, not outcomes. The FedWatch rate-hike probability is high, but it is not a Fed announcement.
• Keep the political risk in proportion. Regulatory proposals could affect AI infrastructure, but Monday’s market action showed that investors were not treating that risk as a reason to abandon the trade altogether.

Frequently Asked Questions

Why did U.S. stocks rally on Monday, November 9?

A sharp decline in oil prices eased some inflation concerns, while technology shares rebounded after the previous week’s AI-driven selloff. All 11 S&P 500 sectors rose.

Did the market recover all of its post-election losses?

No. The Dow moved back above its Election Day close. The S&P 500 and Nasdaq remained slightly below theirs.

Why did Nvidia fall while other chip stocks rose?

Nvidia shares were pressured by news of an independent board investigation into CEO Jensen Huang’s relationship with Alice Huang and allegations by intelligence agencies that she is a Chinese spy. Those allegations are not established findings. An Nvidia spokesperson said Huang remained committed to continuing as CEO.

Does Monday’s rally mean the AI regulation concern is over?

No. Some investors and analysts viewed last week’s selloff as overdone, but concerns about regulation, data-center development, energy use and project costs remain. A rebound shows buyers returned. It does not settle the policy debate.

What should investors watch next?

October CPI on Tuesday, October PPI on Friday, and earnings from CoreWeave, Cisco and Applied Materials. Investors will also watch how the market responds to data that could affect expectations for Federal Reserve policy.

Final Thoughts: A Rebound Is Evidence, Not a Verdict

Monday gave investors a strong counterpoint to last week’s AI selloff. The Dow gained 1,104.02 points. The S&P 500 and Nasdaq posted their strongest daily percentage advances in months. The semiconductor index rallied. Oil fell, helping ease inflation worries.

And Nvidia dropped.

That combination is the story. The market became more comfortable with the idea that fears about AI regulation had pushed the sector too far down. It did not treat every AI company as interchangeable, and it did not give Nvidia a pass on a separate leadership and governance controversy.

So take the rebound seriously, but do not mistake it for certainty. The AI investment case still has to survive policy questions, execution, earnings and the cost of capital. Nvidia’s board investigation will develop on its own timeline. Inflation data will arrive this week, and the market’s expectations for December rates remain elevated.

The practical move is to follow the evidence as it arrives. Watch the CPI and PPI releases. Listen to what CoreWeave, Cisco and Applied Materials say about demand and spending. Keep the distinction between allegations and findings clear. And remember: a market can recover quickly without having finished worrying.
