Key Highlights

● Six S&P 500 sectors rose on Friday, October 30, 2026.

● Energy, staples, utilities, health care, materials and real estate gained.

● Technology was the worst sector by a wide margin.

● Intel's cash-burn warning set off the selling.

Friday, October 30, 2026, was Wall Street's worst day since June, but not every sector shared the pain. While technology stocks were hammered, energy, consumer staples, utilities, health care, materials and real estate all rose. Six of the 11 major sectors finished higher, according to market data.

The headline indexes told only part of the story. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average dropped 572.25 points to 51,770.31 and the Nasdaq Composite lost 747.73 points to 25,437.00. But the equal-weighted S&P 500 fell far less than the cap-weighted index, a sign that the damage was concentrated in megacaps and chipmakers.

What hit tech

The technology sector was the session's worst performer by a wide margin. Intel (NASDAQ:INTC) warned of cash burn this year, citing a weak PC market, Manufacturing bottlenecks and a factory accident in Israel, and its shares posted their biggest one-day drop on record. The Philadelphia Semiconductor index tumbled to 10,688.80, with AMD, Qualcomm (NASDAQ:QCOM), Marvell (NASDAQ:MRVL) and Sandisk (NASDAQ:SNDK) falling steeply.

Amazon (NASDAQ:AMZN) added to the worry with trailing 12-month free Cash Flow of negative $42.4 billion and a signal that Capital spending would rise again next year. Alphabet (NASDAQ:GOOGL), a day after its worst session ever, slipped further. A senior market analyst said: "The message from investors is becoming clearer: strong AI Demand is no longer enough on its own."

Why energy rose

Energy was the day's best sector. Oil prices climbed above $100 a barrel, with December West Texas Intermediate crude up $2.12 to $104.12. Reports that the United States could resume strikes on Iran, tanker incidents in the Strait of Hormuz and a Ukrainian strike on a refinery in Samara all pushed prices higher.

Company results helped too. Exxon Mobil (NYSE:XOM) posted record refining results and adjusted Earnings of $4.23 a share, and Chevron (NYSE:CVX) reported adjusted earnings of $5.28 a share on Revenue of $67.8 billion. Both briefly hit record highs.

Why the defensives rallied

Consumer staples, utilities and health care are classic defensive sectors, made up of companies whose sales tend to hold up regardless of the economic cycle. On a day when investors were questioning the payoff from AI spending, those businesses looked more predictable.

Staples were lifted by results from Mondelez (NASDAQ:MDLZ), Colgate-Palmolive (NYSE:CL) and Church & Dwight (NYSE:CHD), while Coca-Cola (NYSE:KO), PepsiCo (NASDAQ:PEP), Costco (NASDAQ:COST) and Walmart (NASDAQ:WMT) gained in the rotation. Health care hit a record high, according to market data, led by Regeneron (NASDAQ:REGN), whose third-quarter revenue of $5.12 billion beat forecasts of $4.54 billion. Utilities rose as Dominion Energy (NYSE:D), Exelon (NASDAQ:EXC) and Alliant Energy (NASDAQ:LNT) beat earnings estimates.

Friday's split extended a pattern that ran through October. Nine of the 11 sectors gained for the month, according to market data. Only technology and communication services fell, with communication services posting its worst month since April 2022, according to market data. Energy, health care, utilities and staples all posted strong monthly gains.

The Dow, with its heavier weighting in industrial and consumer names, rose about 864 points in October, while the Nasdaq Composite fell about 1,424 points.

What to watch

The rotation will be tested quickly. Apple (NASDAQ:AAPL) reports on Monday, November 2, and Palantir (NASDAQ:PLTR) reports the same day. The midterm elections on Tuesday, November 3, could shift sentiment toward AI and data-center names, and the October jobs report arrives Friday, November 6. Oil remains tied to developments involving Iran and Hormuz, and futures markets are pricing in a Federal Reserve rate hike in December, a Factor that can weigh on rate-sensitive utilities.
