COHU is trading 14.87% down now at $37.27, with the decline aligning with semiconductor-sector pressure and data-center construction concerns. - Shares extended their sharp decline from the November 4 close of $43.98. - No company-specific announcement explaining the November 5 move surfaced in available coverage. - Reuters reported chip and data-center-related stocks fell amid concern greater scrutiny could slow data-center construction; weak smartphone-chip sales at Qualcomm added to semiconductor-sector concerns. This aligns with COHU’s decline but does not establish a company-specific catalyst.
