description: "$AXT(AXTI.US) rose 16%, with the main theme being the demand for optical transmission in AI data centers using indium phosphide substrates — its subsidiary Tongmei signed a long-term indium phosphide contract with a Nanjing-based customer for 2027, locking in approximately $25.4 million, along with an 80% take-or-pay structure, and Northland also raised its price target to $125.Combined with heavy short interest earlier, the short squeeze amplified the volatility. This stock has always been very volatile, with single-day swings of over ten percent being common; chasing highs requires mental preparation."
