Today's biggest winners and losers in the stock market.
On this episode of Stock Movers:
- Applied Materials (AMAT) surges after delivering a surprisingly upbeat sales forecast, signaling that demand for artificial intelligence and memory semiconductors is fueling equipment purchases.
-Rivian (RIVN) shares jump as much as 19% in premarket trading on Friday after the electric vehicle company issued a 2026 delivery outlook range with a midpoint above analyst estimates. The company also said it expects deliveries of its long-awaited R2 midsized SUV in the second quarter.
- Expedia (EXPE) shares tumble despite the online travel company reporting the fastest fourth-quarter revenue growth in three years and first-quarter sales and gross bookings view above Wall Street estimates. Analysts note healthy fundamental outlook, though debates on AI risks to online travel agents likely to persist.
