These surely have not reached extremes, nor any major divergence, at least for now, I think we have more room to go before a major downturn. Of course, a bad earnings report from the like of IBM or INTC, may serve as a trigger to get back to 1842, but right now, I am not expecting that kind of "bad news" here. BP have just crossed back up above their respective 14 DMA, P/C ratio during this last advance have not reached extremes, I am not sure where you see divergences or extremes.
