COHH is trading 4.8% up in pre-market as its 2x exposure amplifies Coherent’s AI data-center demand.
- Coherent reported record fiscal fourth-quarter revenue, driven by AI data-center and communications demand; COHR gained 6.60% on September 4, 2026.
- Despite softer U.S. futures, the move appears primarily underlying-stock and sector-specific rather than broad-market driven; elevated rates and geopolitical tensions remain risks.
- No new September 8 company announcement was identified.
