On May 29, AXT Inc fell 5.04% in regular trading, trading at $117.0/share, with trading volume of approximately $404 million, extending its pattern of sharp pullbacks from recent highs.

On the news front, the stock previously surged over 16% on May 22 after Q1 earnings significantly beat expectations — revenue grew 38.7% year-over-year while losses narrowed substantially — driven by robust AI optical communications demand. Since breaking through its all-time high, the stock has faced consecutive sessions of profit-taking pressure as accumulated gains prompted investors to lock in profits.

Notably, the semiconductor equipment sector traded broadly higher on the day, with Applied Materials up 1.75%, Teradyne up 2.45%, ASML up 1.14%, and Lam Research up 0.95%. AXT Inc's decline against sector strength further underscores that individual stock-level selling pressure from short-term profit realization remains pronounced. Additionally, market concerns have emerged regarding the long-term stability of the company's technology moat, as the evolution of silicon photonics could potentially temper future demand growth for indium phosphide substrates.
