While the copper market was thought to have exhibited considerable strength with yesterday's large-scale recovery, today's price action has been muted with little follow-through to the upside so far. Rising concerns that the Chinese economy may be heading towards a hard landing continue to hang over the market and could make it difficult for copper to gain further ground going into the weekend. While LME exchange copper stocks had a sharp daily decline, weekly Shanghai copper stocks rose to their highest levels since 2002. LME Copper Stocks were 306,375 tons, down 4,750. LME Copper Stocks are at the lowest levels since September 3rd, 2009. LME Copper stocks have declined 18 of the last 20 days. Shanghai Deliverable Stocks were 217,142 tons, up 18,940 or 9.6% for the week. Shanghai Deliverable Stocks have increased 12 of the last 20 weeks. Improving macro-economic sentiment, due in large part to an optimistic outlook towards an eventual resolution to the Greek debt crisis, could help to support copper prices at these current levels. In addition, some traders feel that a set of positively-received US economic data would likely strengthen copper prices later on this morning.
