In about mid-August this year, remember the one day shake-out that drove Probe's share price towards the $1.50 level? The low extreme was so off the wall prices recovered rapidly just like they did today. The low in August rebounded nearly 60% from that low. If history repeats itself then the low of $2.02 may equate into roughly $3.20, just on that basis.
