UnitedHealth Sells Off, American Airlines Falls, Corning Jumps

On this episode of Stock Movers:
- UnitedHealth Group (UNH) forecast a decline in 2026 revenue, the first annual contraction in more than three decades, as the insurer falters in its attempt to rebuild confidence with investors after a stunning fall last year. The news was the second blow to shareholders in as many days. Late Monday, the US proposed holding payments to private Medicare plans flat next year, a huge disappointment that caused the stock to tumble as much as 10% in after-hours trading. Shares plunged again after the company’s results, falling nearly 18% in New York on Tuesday when markets opened. The decline erased more than $55 billion in market value.
- American Airlines (AAL) said it’s poised for a strong year as the carrier ramps up premium offerings, but first it’s trying to survive winter weather that’s prompting thousands of cancellations at major US hubs. The Texas-based airline already postponed almost 800 flights Tuesday, according to FlightAware — the most of any major carrier — after scrapping more than half on Monday amid snow and frigid temperatures in large parts of the eastern US.
- Corning (GLW) announced a multiyear, up to $6 billion agreement with Meta Platforms Inc. to supply optical fiber, cable, and connectivity solutions for Meta’s advanced data centers supporting its AI ambitions. Shares of the company rallied in trading on Tuesday.
