COHU is trading at $52.12, up 6.69% from the October 26 regular-session close of $48.85; the move coincides with a semiconductor-stock rebound after the recent AI-related sell-off, but no company-specific catalyst was identified.

  • SOXX was up about 3% during the session, supporting sector strength as context but not confirming a specific reason for COHU’s after-hours jump.
  • Cohu’s next scheduled catalyst is its Q3 2026 results on October 28, after the close.
