The most active November copper contract on the Shanghai Futures Exchange fell 0.6 percent to 55,910 yuan ($8,800) per tonne on Friday, pushed down by Shanghai equities amid thin trading volumes. Shanghai copper is up 0.8 percent on the week. Traders said contracts' real trading volumes were low as Chinese speculators were still focused on agricultural futures.
"Taken at face value, Shanghai copper trading volumes of over 300,000 lots today were already relatively small. And this number includes open positions being moved to November," said one trader.
