COHU is trading 4.7% down at $49.27 after falling from its August 27 close of $51.69, with no fresh company-specific catalyst identified for August 28, 2026.
- The broader market is modestly higher, so broad index sentiment does not appear to be driving the decline.
- Latest disclosures remain positive, including increased fiscal 2026 revenue-growth guidance and expanded manufacturing capacity.
- An executive stock sale occurred August 19 but does not directly explain today’s decline; confidence remains low pending possible delayed or newly emerging news.
