On September 8, Applied Optoelectronics rose 5.01% overnight, trading at $110.85/share, with turnover of $13.57 million. The optical communication sector staged a broad rebound, with peers Lumentum up 3.34%, Ciena up 2.73%, and Nokia up 3.79%.

On the news front, OpenAI recently launched its GPT-6 Astra model, a significant leap in frontier AI capabilities that has fueled expectations for rising demand in computing power and high-speed optical interconnects. Separately, Goldman Sachs issued a research note materially raising its global shipment forecast for 1.6T and above optical modules by 29% to 61%, reinforcing the bullish outlook for the sector.

As a core beneficiary of AI-driven optical module demand, Applied Optoelectronics had previously come under pressure following a $600 million at-the-market equity offering announced in late August, which triggered dilution concerns and a sharp selloff exceeding 16%. The current move represents a sector-wide rebound from that pullback, supported by strengthening demand catalysts across the optical communication supply chain.
