From the recent rally the low end was around 21-22, but if we were to take a step back, the low is lower.
This version of the chart suggests the market can rally to +1150 given the VIX declines to the high teens.
(The Vix is the moving Blue Line, the SP500 is the moving Black. The Dotted Red horizontal line is the very low-end for the Vix under the overlay chart condition, the Blue horizontal line is the low end Vix support so far for this current market rally. The Solid Red horizontal line is the top end resistance for the Vix.)
The Vix has entered its low end, and that would trigger some selling. I think a retest of the very low end is very possible.
I will let the pundits create a reason for the move upward ;), but the possibility of a push upward is not out of the question.
