More and more I'm thinking we may have sideways motion in the form a of a triangle on SPX. Weekly BBs are starting to show sideways action and lower weekly BB and MAs (200 weekly, 50 monthly) are all pointing to support around 3650-3600. This analysis is wrong if they can get over the August 22 high of 4325, which to me is doubtful.
It's possible they ramp this one more time into the 4200s with CPI but it would only concern me if they could start getting over the 4325 mark. Anything over 4200 would be a gift to bears in my opinion. Many large cap stocks and other indexes are at a backtest of important resistance, a little higher would not be an issue.
I'm thinking this could be the high for quite a while. If I'm right, a D leg down to 3600 would be followed by an E, but the E should not get over the current C leg high.
Good luck!
