COHU is trading 10.1% up at $50.62 after semiconductor stocks rallied broadly on renewed AI-infrastructure optimism.
- The sector move followed Nvidia’s agreement to acquire Hugging Face for approximately $12.9 billion, reinforcing enthusiasm for AI-related chip demand.
- No new Cohu-specific announcement, earnings release, or analyst action was identified on September 4, 2026; the gain therefore appears primarily sector-driven.
