December copper posted large gains during overnight trading, with prices reaching their highest levels since mid-May. Shanghai copper prices reached a new 3-month high, with many traders pointing to news that China approved 1-trillion-yuan worth of infrastructure projects this week as a key supportive factor for the market. Sharp gains in Asian equity markets in reaction to yesterday's ECB meeting results and a slide in the Dollar down to a new 3 1/2-month low were also widely seen as positive factors for copper.
