COHU is trading 4.68% up at $53.09, with no fresh company-specific announcement or confirmed catalyst identified for September 8, 2026.

  • Available coverage points to earlier conference activity and the July earnings beat.
  • Cohu previously reported stronger-than-expected results and raised its outlook, but that news predates today’s move.
  • The broader market is lower, so the gain is not clearly explained by index sentiment.
