Approaching end-of-quarter results and "window dressing" offers some price support across the base metals complex but overall the market isn't showing much interest, says a London-based broker, adding that a backwardation continues to curb selling interests. He notes increased volume in aluminium, while "lead and nickel are looking vulnerable today, at the lower part of their range, but not weak enough to attract panic selling," but any move lower would find dip buyers, he says. LME three-month copper trades flat at $6,850/ton, aluminium is at $2,740/ton, +0.3%, nickel +1.2% at $43,000/ton, lead is at $1,894.85/ton up 0.1%.
