The past 3 days in particular have been quite divergent among the big four indexes. The past month the only spot I can see where this happened was on Nov 3rd, and it quickly ironed itself out within a day. This one is at 3 days and counting. Healthy markets shouldn't have sustained divergences like this. A day here or there, fine, but this one is worth monitoring. QQQ and SPY doing well, IWM and DIA getting spanked.
