Good chances a rebound at least tomorrow morning.
ISEE equity only index readings now is at 232, which is the 2nd highest readings since March bottom. The last similar extreme readings was May 5 (225) and May 29 (237), SPX was up huge after both date. The big differences between today and those 2 days were that today is a huge down day. So will today be different than that of those 2 days? Well, I have no idea.
