Shanghai copper gains

Shanghai Futures Exchange copper built on overnight gains to close up 8.7 percent on Friday, amid a buying frenzy by speculators. In Shanghai, aluminium struck 14,255 yuan a tonne, the highest since September 2014. Gains came amid a widespread rally in steel, coal and iron ore prices after China curbed domestic coal production earlier this year, which has seen prices of the raw material doubling in the past two months.
"It's been building in the past couple of weeks, and Trump has kicked it along in the past few days," said analyst Daniel Hynes of ANZ in Sydney. "It's been more a shift around where the market sees demand over the course of 2017."
