Copper rises

Beijing : London copper prices traded higher on Wednesday, on course to end a four-day losing streak, as a weaker dollar provided some respite after the metal hit a three-month low in the previous session following another big increase in inventories.

Three-month copper on the London Metal Exchange was up 0.3 percent to $6,772 a tonne by 0219 GMT, after closing down 1.4 percent on Tuesday and touching $6,730 a tonne, its lowest level since Dec. 14.

LME copper stocks grew by a further 3,200 tonnes on Tuesday to 322,475 tonnes, bringing this month´s rise to 61 percent.

The most-traded May copper contract on the Shanghai Futures Exchange was down for a fourth day, falling 0.9 percent to 50,910 yuan ($8,043) a tonne. It touched a low of 50,640 yuan, its lowest since Sept. 25.

The dollar index was down 0.1 percent at 90.30. A weaker dollar makes metals cheaper for holders of other currencies and can support prices. 
