BEIJING- Prices of copper and other metals in London edged up on Monday as previous price falls triggered some buying opportunity, while looming concerns over global economies weighed on sentiment, capping further gains.

Three-month copper on the London Metal Exchange climbed 0.2 percent to $9,074 per metric ton, while the most-traded September copper contract on the Shanghai Futures Exchange slid 1.3 percent to 73,000 yuan ($10,195.53) a ton.

Bullish factors previously such as strong China demand and smelters’ output cut faded but investors still buy the dip given the long-term optimism towards copper, traders said.

LME copper lost 8 percent over the past four weeks. Analysts at ANZ expect metal prices to bottom out soon as current prices could trigger a supply response.

US job growth slowed more than expected in July, while the unemployment rate increased to 4.3 percent . This could heighten fears that the labor market is deteriorating, potentially making the economy vulnerable to recession.

The data came on top of weak manufacturing activities in China, triggering a global selloff in risk assets.

The job report on Friday, however, fueled expectations of deeper interest cuts by the US Federal Reserve, starting from September. That could bolster industrial activities and metals demand.
