Celestica Inc. is trading 11.6% down today at $404.98 as investors lock in gains following a sharp multi-day surge fueled by AI networking optimism.

  • The decline aligns with broader technology sector weakness as the Nasdaq falls and semiconductor sentiment cools following Broadcom’s recent earnings reaction.
  • No company-specific negative catalysts were identified, suggesting the move is primarily driven by profit-taking and sector rotation after the stock's recent outperformance.
