COHU is trading 5.21% up now at $50.50 in pre-market, with no clear company-specific catalyst identified for August 31, 2026.
- Latest disclosures were an August 12 investor-conference announcement and July 30 second-quarter results, rather than fresh overnight news.
- The broader market is modestly lower, so the pre-market gain does not appear driven by index sentiment.
- Trading activity and volume details were unavailable.
