DBC, the commodity index ETF, is sending mix signals. The correlation between DBC and the S&P is pretty good, but while the S&P is trading about 3 % above it's 2011 high, DBC is still about 17 % below is 2011 high. It also broke it's"short" term up-trend line. Not sure what to make of this is it sending valid signals about the state of the economy or the correlation between the two is simply deteriorating ?......
