BWS Financial analyst Hamed Khorsand noted that news of a U.S. Department of Commerce export ban against ZTE (ZTCOY) caused optical component stocks to come under significant selling pressure yesterday. However, while AXT, Inc. (AXTI) gets bundled with optical component stocks sometimes due to its indium phosphide crystals being used for optical components, he views the pressure on the stock as unwarranted. AXT has a diversified customer base with multiple end markets and no customer representing over 10% of revenue, noted Khorsand, who maintains a Buy rating on the stock.
