On June 5, AXT Inc declined 5.32% overnight, trading at $100.35/share, with trading volume of $4.15 million. The decline continues the stock's high-level correction pattern since hitting an all-time high on May 22, when shares surged over 16% in a single session following a Q1 earnings beat featuring 38.7% year-over-year revenue growth and significantly narrowed losses driven by strong AI optical communications demand.

The sustained sell-off has been amplified by intensive insider selling. CEO Morris S Young sold 197,498 shares on June 1-2 at prices above $112 per share, while Director Jesse Chen filed to sell approximately 109,526 shares valued at roughly $11.59 million. These transactions signal potential high-valuation recognition by management and have weighed on investor sentiment.

The broader Semiconductor Equipment sector declined notably, with ASML down 3.91%, Lam Research down 2.81%, Teradyne down 2.74%, Applied Materials down 2.44%, and KLA-Tencor down 2.16%, further pressuring the stock. Longer-term concerns persist regarding silicon photonics technology potentially displacing indium phosphide substrate demand and China's indium export controls constraining shipment capacity.
