Weekly Roundup: Intel Jumps, Zoetis Plummets, Datadog Soars

Today's biggest winners and losers in the stock market.
On this episode of Stock Movers, we take a look at some of the biggest gainers and decliners of the week:
- Intel (INTC) rallied on Friday after the Wall Street Journal said the company reached a preliminary agreement with Apple to manufacture some of the chips in its devices. Bloomberg reported on Monday that Apple had held exploratory discussions about using Intel and Samsung to produce the main processors for its devices in the US, a move that would offer a secondary option beyond longtime partner Taiwan Semiconductor Manufacturing Co. Intel and Apple reportedly have been in talks for more than a year and it’s still unclear which Apple products Intel would make chips for.
- Zoetis (ZTS)’s shares plummeted after the world’s largest animal health company missed first-quarter sales expectations and cut its 2026 forecast as Americans spent less on their pets. The maker of medicines for pets and livestock said it would generate full-year earnings of as much as $7 a share, a top-end cut of 10 cents a share that came in below the average estimate from analysts. The biggest hit in the quarter was in drug sales for US pets, which declined 11% due in part to rising inflation, the company said in a statement. Shares fell 22% to $87.31, the biggest drop on record in trading on Thursday.
- Datadog (DDOG) surged by the most in more than six years after the software developer raised its full-year outlook for sales and earnings, far exceeding Wall Street’s expectations. Revenue is now expected to total $4.3 billion to $4.34 billion, above analysts’ estimates of $4.09 billion on average. The company also raised its adjusted earnings guidance to as much as $2.44 a share, from $2.16 at the previous top of the range. The company’s shares gained 31% to close at $188.73 in New York on Thursday, their highest settlement price since September 2019.
