Crude oil fell sharply again and copper prices have continuously brought profit risks and economic repression recently. Copper prices fell slightly on Tuesday, and the state of mind in preparing materials before the International Labor Day was also slightly affected. Judging from the current situation, the supply of recycled copper continues to be in short supply. Guangdong's electricity and copper stocks continue to fall to over 40,000 tons and high water prices have some support for the copper market. The profit trend after the rebound in copper prices is normal. The global relief economy's increased exchange and the increasing subsequent demand are favorable to the copper market, and the general trend is upward.
