The copper market has now risen up to the highest price levels since September 19th of 2011. Many traders feel that copper was supported by an accommodating monetary policy stance from the Federal Reserve yesterday, and that vibe might continue to resonate in the market today unless US economic data comes in weaker than expected later on this morning. In the event that the market is presented with weaker US data, some traders feel it possible that today's numbers might be discounted because of the Fed's promise to use additional quantitative easing measures in the event that it is needed. While copper might be partially weakened by news of rising copper production from Anglo American Plc overnight, the copper market hasn't paid that much attention recently to classic supply side developments.
