Good question, I was wondering the same thing. Where is the cash going.

Hard selloff into the last second before the close then instant big buying right after the market close.

NVDA now up $25 after hours on earnings.

The wicked selloff maybe a bear trap. See tomorrow. Gap up should cause a lot of buying. Not to say the move down is over, but develop into a bull trap in coming sessions. Or just get down to the 200 test straight away. But why not a bull trap before that just for kicks!
