SPX

If SPX can get back over 4194 you can see a move back towards 4220. Over 4220 can make its way into the previous ATH of 4238. If SPX can't hold 4150 it can fall to 4118. Under 4118 can cause a bigger selloff down to 4068. If 5/12 low breaks, I think you can see a 80 point sell off down to 3/17 previous ATH of 3980.
