November Copper futures rallied, with prices up for the fifth week in the last seven, but pulled back from a high of $5.26. The rally occurred despite a strengthening dollar, which is a reversal of the historical inverse correlation between the two. The market is also reacting to Canadian miner Teck Resources cutting its production guidance due to challenges at its Chilean mine. The mine's recent production of 170,000-190,000 tonnes is down from the previous range of 210,000-230,000 tonnes.
