COHH is trading at $11.25 (+26.98%) on August 7, 2026, after Coherent and related optical-communications stocks rallied sharply.
- Coherent gained more than 14% after the open, while Lumentum, Corning, and Marvell also advanced, indicating a broad sector move rather than an isolated ETF event.
- COHH targets 2x the daily performance of Coherent, so the underlying stock’s surge mechanically explains most of the ETF’s gain.
- Coherent’s upcoming August 12 earnings release may also be encouraging positioning; no separate company announcement was identified for August 7.
