I just wanted to reiterate this:
Copper is often being looked to as a leading indicator for global economic growth. Whether that's true this time around or not is fairly irrelevant for my note here. Looking at the chart below I note a downward-trending channel that Copper is now looking to break out of to the upside. What else? Copper last week managed to close above the 50 day moving average..i.e., it so far looks like the 50 dma is holding as support. Personally I need to see a little more upside and volume here, but I could see this evolve into a good long setup shortly.
