RBC Capital Markets went to town on the A series warrants scooping up to 90k of the 134k volume today.  The big pull back in Aris has their fair value in the low 30 cent range yet the Vacuum gobbled everything up to 39 cents.  This buyer is showing a lot of future stock price growth in over paying for the A series warrants.

I checked the B series and they were down 11% on 1730 shares traded.  The Vacuum seems to only like the A series, probably for more leverage.
