Friday, October 30, 2026, was a rough session for most stocks. The S&P 500 fell 140.32 points to 7,580.07, the Dow dropped 572.25 points to 51,770.31, and the Nasdaq Composite tumbled 747.73 points to 25,437.00, its worst day since June 5. Intel (NASDAQ:INTC)'s cash-burn warning and Amazon (NASDAQ:AMZN)'s results triggered a broad chip and AI selloff.

Yet a handful of names rallied hard. Regeneron Pharmaceuticals (NASDAQ:REGN) was the S&P 500's top gainer, with Global Payments (NYSE:GPN) and GoDaddy (NYSE:GDDY) close behind. Each had a specific catalyst.

Regeneron's blowout

Regeneron soared after third-quarter revenue reached $5.12 billion, well ahead of the $4.54 billion analysts expected. Non-GAAP Earnings came to $20.07 a share against a $16.24 estimate. Rock and Turner also cited $1 billion upfront from an expanded deal with Sanofi (NASDAQ:SNY) and a Food and Drug Administration approval for Pasatru. Market reports said that Regeneron raised its full-year outlook.

The gain fit a broader pattern. Health care was one of the day's stronger sectors and hit a record high as money rotated away from technology into defensive areas such as consumer staples, utilities and energy. Sanofi, Regeneron's partner, also rose after beating expectations and raising its 2026 sales forecast.

A reported buyout at Global Payments

Global Payments jumped after a market report said that Private Equity firm Clayton, Dubilier and Rice is pursuing a buyout alongside GTCR, Global Payments' largest shareholder. The reported deal would be worth about $40 billion including debt. Before the jump, the company's equity was valued at about $23 billion, with net Debt above $17 billion. No price has been reported.

GoDaddy and the other winners

GoDaddy rose sharply after third-quarter earnings of $2.08 a share beat estimates of $1.85 to $1.90. Revenue reached $1.342 billion, ahead of forecasts near $1.33 billion. Normalized EBITDA came to $449.3 million against $440.2 million expected, and free Cash Flow of $480.8 million topped the $461.1 million estimate.

The company said it expects to land at the high end of its full-year revenue guidance. Its Airo AI product's annualized revenue run-rate doubled to more than $100 million, a rare example this week of an AI story that investors rewarded.

Several other companies bucked the trend. Cboe (CBOE:CBOE) Global Markets climbed after a record quarter and an extension of its exclusive S&P Dow Jones Indices license to 2051. CoStar Group rose after raising its 2026 guidance, and Veralto (NYSE:VLTO) gained after lifting its earnings outlook. Exxon Mobil (NYSE:XOM) and Chevron (NYSE:CVX) briefly hit record highs on strong refining results as oil traded above $100.

An Investment strategist pointed to the breadth beneath the headline: "The market is much more broad than people generally want to give it Credit for." The equal-weight S&P 500 fell far less than the cap-weighted index, a sign the damage was concentrated in megacaps and chips.

What to watch

For Global Payments, the key question is whether a formal offer emerges and at what price. Regeneron investors will watch the rollout of its new approval and the expanded Sanofi alliance, while GoDaddy's progress with Airo will be tracked as a test of AI monetization.

The broader market faces Apple (NASDAQ:AAPL)'s report on Monday, the midterm elections on Tuesday and the October jobs report on Friday, November 6.
