Select A-share chemical stocks rallied; Sinochem International and Heyuan Gas
hit the daily trading limit, Kangda New Materials rose over 5%, and Haohua
Technology, Zhejiang Longsheng and Dinglong Technology also advanced. Market
reports say overseas supply-chain tightening coupled with a burst in downstream
demand has widened the supply–demand gap, sending tungsten hexafluoride (WF6)
prices sharply higher.
