AXT Inc's stock experienced a sharp intraday decline of 5.30% as investors continued to take profits following the stock's recent surge to an all-time high.

The sell-off reflects ongoing pressure from investors locking in gains after the stock's significant rally, which was initially driven by stronger-than-expected first-quarter earnings featuring 38.7% year-over-year revenue growth and a notable narrowing of losses, coupled with robust expectations for AI optical communications demand.

Notably, the decline occurred despite broad strength in the semiconductor equipment sector during the session, underscoring that the movement is primarily due to stock-specific profit-taking rather than any industry-wide weakness.
