Copper stock rise Friday on Shanghai Futures Exchange doesn't indicate Chinese demand below expectations, says senior trader Haihua Shen at Maike Futures. Notes stock rise of 6,027 tons to 46,913 tons follows positive domestic-international price ratio encouraging high level of copper imports, leading to temporary surplus; "the level of Chinese copper in demand is in line with my expectations. Demand is picking up gradually and should continue during the second quarter." LME 3-month copper is up $25/ton vs Friday PM kerb at $6,155.
