Why Is AXT INC (AXTI) Stock Up Today?

AXT Inc. stock surged 19.26% to $97.36 on Monday as part of a broader rally in the optics sector driven by rising demand for indium phosphide, a key material in optical interconnects for artificial intelligence applications. The stock opened with a 5.1% gap up and climbed steadily through the session, reaching an intraday high of $97.60. AXTI’s move was part of a broader upswing in the sector, with peers like Coherent and Lumentum also posting gains.

What Happened
