Friday’s close was the sixth consecutive positive close in a row. In the following chart, you can see this is pretty rare and has a high probability of leading to a pullback the following day (I drew a yellow line for the 5/6 days up from 2006-07 to clarify where they occurred). There is no telling the size of the move this way. It could be .1 /ES point, a camel tit or a horse nuke. All you really have is the strong expectation that the day itself should close lower. If Monday’s close is higher, than what I said above would be equally as true for Tuesday.
Also reflecting the possibility of a weekly pullback is that weekly breadth is overbought. I have marked on the following chart that breadth is in an area that can lead to a 1-3 or 5-10 day pullback. That said, the breadth of this move has been very bullish (also shown on chart), which is exactly what you want to see when you break out of a congestion area (1085-1120). Since we are only 25 points above the aforementioned area, it seems probable that a pullback could take price back into that range. However, unless breadth is really negative (multiple +2 std. dev. days in my strength reading), it should be another dip to buy.
