On September 18, Applied Optoelectronics rose 5.44% in regular trading, trading at $103.24/share, with turnover of approximately $506 million. The gain marks a continued technical rebound following the sharp selloff on September 14, when the broader optical communications sector was hit hard after three major AI companies publicly called for slowing frontier model development, sending AAOI down over 9% in a single session.

The optical communications sector broadly strengthened in recent sessions, with peers Lumentum up 2.75%, Coherent up over 4%, and MaxLinear up over 4%. Multiple analysts have characterized the prior selloff as emotion-driven, noting that the AI slowdown rhetoric remains at the verbal level with no actual capital expenditure cuts or order cancellations materializing. Industry fundamentals remain supportive, as the shift from copper to optical interconnects in multi-rack scale-up architectures continues to expand the sector's addressable market. Goldman Sachs recently raised its global optical module market forecast significantly, projecting the market to reach approximately $1,295 billion by 2028.

Investors should note that the company filed a $600 million ATM equity distribution agreement in late August, which triggered a single-day drop exceeding 12% on dilution concerns.
