SHANGHAI, Jul. 24 (SMM) – As LME copper extended weakness overnight, SHFE 1211 copper contract, the most active one, started RMB 470/mt down at RMB 54,300/mt Tuesday. After the opening, the contract continued to fluctuate around the opening price and touched a low at RMB 54,170/mt. During major trading hours, the HSBC announced that the HSBC China manufacturing PMI rose from the previous data and lifted LME copper prices.

At the tail of trading though, short selling appeared again and pressured SHFE copper prices down below the daily moving average again and returning to around the opening price.
