AXT Inc's stock plummeted 6.10% intraday, reflecting significant selling pressure after recent gains.

The decline is attributed to profit-taking by investors following the stock's surge to a 52-week high, driven by better-than-expected quarterly earnings. Additionally, a broader retreat in the semiconductor sector, with key players like ASML Holding and KLA-Tencor also trading lower, amplified the downward momentum.

Despite strong fundamentals, including a 38.7% year-over-year revenue growth and a backlog exceeding $60 million, the rapid prior rally has triggered repeated sell-offs, highlighting short-term volatility in the sector.
