On August 18, AXT Inc fell 5.37% in regular trading, trading at 91.21 USD/share, with turnover of $221 million. The stock had surged over 17% in the prior session, creating significant short-term accumulated gains that triggered pronounced profit-taking pressure during the session.

At the sector level, the Semiconductor Equipment industry saw broad-based weakness. Among individual stocks, Lam Research fell 5.6%, Teradyne fell 5.8%, Applied Materials fell 4.89%, ASML Holding fell 3.45%, and KLA Corporation fell 3.44%, with the overall industry downturn dragging on individual names.

Additionally, the market continues to price in geopolitical risk surrounding China's indium phosphide export controls. AXT's core indium phosphide production capacity resides at its Chinese subsidiary Beijing Tongmei, and uncertainty around export license approvals remains a persistent overhang on valuation. Global indium phosphide substrate supply-demand gap exceeds 70%, yet AXT's ability to serve overseas customers hinges entirely on Chinese regulatory approval, creating a material tail risk that constrains the stock's upside despite strong Q2 results.
