AXT is trading 10.16% higher at $67.90 as renewed enthusiasm for AI infrastructure and semiconductor demand lifts the compound-semiconductor group.
- Recent momentum also reflects AXT’s record second-quarter revenue and strong third-quarter outlook.
- A multi-year indium-phosphide supply agreement with Lumentum is another supporting development.
- Those developments predate September 8, 2026; with the broader market lower, sector-specific AI enthusiasm is the likelier immediate driver.
