🟢 Amentum is trading 4.17% up

Amentum is trading at $20.99, up 4.17%; the reason for the gain remains unclear.

• No verified company-specific announcement dated October 22 clearly explains the move.
• The Sellafield preferred-supplier selection was announced September 30, and Cheyenne Mountain contract coverage predates this session.
• Amentum is rising while the supplied market context describes broad index declines, so the move does not appear to track the wider market direction.
