Today's biggest winners and losers in the stock market, a look at the notable movers:

On this episode of Stock Movers:
- SpaceX (SPCX) shares ended higher on Tuesday, snapping a three-day selloff that wiped out more than $600 billion from the Elon Musk-led rocket and satellite company’s market value. The stock gained 1% to close at $156.11 after a choppy session that saw shares slip as much as 4.8%, then jump 7.1% before paring much of that advance by market close. The volatility came amid a broad-based slide in technology and other high-momentum stocks after a selloff in Korean chipmakers stoked fears about the rally in companies involved in artificial intelligence.

- Quantinuum (QNT) is climbing as traders rotate into quantum‑linked assets after the administration issued sweeping executive orders aimed at accelerating quantum computing, strengthening quantum supply chains and securing national systems against future quantum‑enabled cyber threats.

- Carnival (CCL) shares slump as much as 11% on Tuesday after the cruise operator cut its net yield for the full year, citing the prolonged conflict in the Middle East. The company also gave a third-quarter adjusted earnings per share forecast that missed the consensus estimate.
