COHU is trading 7.07% down at $40.87, as semiconductor and data-center-related shares weaken amid concerns election results could bring tighter scrutiny and slow data-center construction.

  • The decline extends the sharp fall from its November 4 close; Reuters reported chip-sector losses continued November 5.
  • The move appears sector-led; no clear company-specific catalyst was found.
  • Cohu’s scheduled November 10 Investor Day is upcoming, not a new announcement explaining the decline.
