March copper prices this morning are sitting as much as 15 cents a pound below last week's highs. While many traders feel that the copper market has recently tended to focus on the demand side of the equation recently, the market might have received some pressure overnight from news of higher copper production from both Zambia and Kazakhstan. Copper prices may still have some residual support from ideas of improving Chinese demand in the near future but recent news from China has been not been widely seen as positive. Like other physical commodity markets, the copper market may need to see something definitively upbeat from the US Retail Sales data to support the market. Ideas that Chinese copper demand will remain soft was given additional credence by news of rising Shanghai copper stocks last week, and it is unclear if the copper market can discount negative Chinese news in favor of any positive US news flow.
