Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:
- Cava Group (CAVA) reported fourth-quarter sales growth and gave a rosy outlook for 2026, outperforming its fast-casual rivals and bucking expectations for a slowdown. Sales from established restaurants are seen expanding 3% to 5% this year, with the company citing price increases and customers opting for more expensive options as helping to offset a decline in store visits. Cava shares jumped 9.2% after the close of regular trading in New York, with the stock having advanced nearly 16% so far this year.

- PayPal (PYPL) closed up 6.7% to $47.01 in New York Tuesday, giving it a market value of $43.3 billion after Bloomberg reported that Stripe is considering an acquisition of all or parts of PayPal Holdings Inc., according to people familiar with the matter. The deliberations are early and there's no certainty they'll lead to a transaction, the people said.

- Novo Nordisk (NOV) next-generation weight-loss drug CagriSema had disappointing trial results, sparking calls for a radical shift in the company's strategy. Some investors are urging Novo to diversify away from diabetes and obesity, citing the risk of relying on these two areas, and suggesting fields such as rare diseases, heart disease, or cancer treatment.
