Closing Bell: Arm Soars, JetBlue Surges, Energy and Chemical Stocks Fall

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

On this episode of Stock Movers:

- Arm Holdings Plc (ARM) shares rose by the most in almost a year after the company announced plans to sell its own chips for the first time — a move forecast to generate about $15 billion annually within five years. Meta Platforms Inc. will be the first major customer for the company’s chip, called an AGI CPU, Arm said Tuesday at an event in San Francisco. The product will have as many as 136 cores — a measure of processing power — and draw 300 watts of electricity, according to the UK-based company. Taiwan Semiconductor Manufacturing Co. will produce the chips.

- JetBlue (JBLU) shares surge after reports from Semafor saying the airline is considering the option of selling itself to a competitor. The US airline has hired advisers to explore the viability of a deal, and is considering scenarios of a tie-up with United Airlines Holdings Inc., Alaska Air Group Inc. or Southwest Airlines Co., and how such a combination would sit in the political and regulatory environment, the publication said.

- Energy and Chemical stocks fell today as investors weighed Iran rejecting a US ceasefire proposal.
