On May 29, AXT Inc fell 5.79% in regular trading, trading at $107.76/share, with trading volume of approximately $181 million, extending a pattern of sharp pullbacks from recent highs.

On the news front, the stock had surged over 16% on May 22 after Q1 earnings beat expectations (revenue up 38.7% year-over-year, losses significantly narrowed) and strong AI optical communication demand propelled shares to new all-time highs. Since then, accumulated profit-taking pressure has driven consecutive sessions of selling. Additionally, market concerns that silicon photonics technology evolution could weaken long-term demand for indium phosphide substrates — AXT's core product — have further weighed on sentiment regarding the company's technology moat durability.

Notably, the broader semiconductor equipment sector traded higher today, with ASML up 2.61%, Applied Materials up 1.85%, KLA up 1.53%, and Lam Research up 1.19%, making AXT's decline against the sector trend a further indication that individual stock-level profit realization pressure remains the dominant near-term factor.
