AXT Inc's stock soared 16.02% during the intraday session on Monday, marking a significant upward movement for the semiconductor materials company.
The sharp rise is attributed to a technical oversold rebound following a period of sustained profit-taking. Fundamentally, the company is benefiting from China's continued tightening of export controls on indium phosphide (InP) and upstream high-purity indium, with rejection rates for export applications from U.S. and Japanese companies reportedly exceeding 80%.
As a leading U.S.-listed InP substrate supplier, AXT commands a scarcity premium in a globally constrained market where it and a few other companies collectively control over 90% of production capacity. Additional support came from broad-based strength in the semiconductor equipment sector, which rallied strongly alongside AXT's movement.
