Affected by the pressure of profit-taking and the increase in foreign epidemics, copper prices fell slightly on Tuesday. LME copper continued to hover around US$ 5,300. Electricity copper premium also fell after rising continuously. Factory enterprises were also slightly cautious in purchasing. At present, the supply of recycled copper is still tight due to a small import volume, which continues to boost electricity copper consumption. It is expected that short-term copper prices will have some profit pressure after a continuous rise, but the general direction is still slightly stronger.
