Nasdaq Falls 5.5% Into Correction as AI Trade Unravels: What to Watch

Wall Street's AI trade just had its worst day in months. The Nasdaq Composite fell 5.52% on Thursday, its worst session since April 2025, and closed in correction territory, more than 10% below its Oct. 6 record close, Fox Business reported.

The damage wasn't limited to tech. The Dow dropped 1,833.06 points, or 3.44%, to about 51,868. The S&P 500 lost 4.36%, and all 11 S&P sectors closed lower.

Chips took the worst of it. The Philadelphia Semiconductor Index plunged more than 12%. Nvidia sank about 9.3%, and Micron fell 17%. Meta dropped nearly 4%, Tesla slid about 10.8%, and data center operators IREN, Applied Digital and Nebius each lost more than 14%. The Nasdaq-100 erased roughly $2.3 trillion in market value, according to Yahoo Finance.

The trigger was politics. Democrats swept Tuesday's midterms, and several of them ran against data center buildouts as electricity prices became a campaign issue. On Thursday evening, Texas Governor-elect Gina Hinojosa said in a CNN interview that Texas would "have laws to protect Texans, and we need to stop what we are doing with data centers until we have those protections."

eToro analyst Jakub Rochlitz told Fox Business the market now reads the AI buildout as becoming "slower and more expensive." That rewrites growth expectations across the whole supply chain, from chip designers to power producers like GE Vernova and Constellation Energy.

"With a relatively small number of technology and semiconductor stocks now carrying so much weight, weakness in those names quickly translates into sizeable falls for the Nasdaq and S&P 500." — Stuart Clark, Portfolio Manager, Quilter

Clark's point lands hard when you look at the numbers. A Motley Fool tally found six stocks made up 30.8% of the S&P 500 as of Nov. 2. When that few names carry that much weight, an AI wobble becomes an index problem.

There's a second story under the political one. Nomura cross-asset strategist Charlie McElligott argued the main driver isn't a sudden collapse in fundamentals. He sees hedge funds rushing to lock in 2026 profits, a momentum unwind that's been "wildly acute" for more than a month.

The monthly moves back that up. Lam Research is down 36% over the past month, Applied Materials has shed 30%, AMD is off 22% and Nvidia is down 15%. These were the year's winners, and they're being sold first.

Retail investors didn't buy the dip either. Vanda Research said everyday traders net-sold $358 million of individual U.S. stocks as of 2:58 p.m. ET, their biggest selling day since March 17, 2020. Vanda's Viraj Patel called it "total capitulation." The VIX, Wall Street's fear gauge, jumped 61%, The Guardian reported.

Friday brought a partial bounce. Nasdaq-100 futures rose about 1.6% and Micron was up roughly 9% in early trading, CNBC reported, but Dow futures were down about 444 points. Europe's Stoxx 600 was down 1.7%, and the selloff hit Asia hard, with Japan's Nikkei and South Korea's Kospi sinking 6% and more than 8% in early trading.

Is this a buying chance? Strategists are split. Argent Capital's Jed Ellerbroek called it "the capitulation phase" for data center capex beneficiaries but said the magnitude of the moves looks "outsized." Saxo's Neil Wilson said the selloff "looks totally overdone," though he added the market needs to find stability first.

The counterpoint is that the political risk is real and not priced in yet. Dan Ives warned that Democratic control of the Senate will "create some major hurdles for AI and tech legislation" over the next two years. President Trump pushed back Friday, writing on Truth Social that data centers are "GOLD" and that he'd work with any state that supports them.

Past Nasdaq corrections show tech stocks often find their footing in three to six months, CNBC noted, but trading can stay rocky in the meantime. Don't expect a straight line up.

For your own portfolio, start with a plain question: how much of it is AI and semiconductors, including through index funds? If a 5% Nasdaq day made you want to sell everything, your exposure may be bigger than you planned. Resist the urge to make that call on a panic day.

Near term, watch Friday's October jobs report. Economists expect 59,000 new jobs and a 4.2% unemployment rate. After that, the signals that matter are state-level data center legislation and whether the chip names that bounced Friday can hold their gains.

Bottom line: this was a political shock landing on a crowded trade, so judge your AI exposure by the fundamentals, not by the worst day of the year.
