It is reasonable volume to grab shares. I think I have a clue who is selling. I think warrant holders that are converting, and selling while holding their original common shares. Just to hedge their bets.
But who would be buying if they had your attitude?
I'd take a 28% gain for the year in a deeply red market any day. Zooming in on one hour of one day and using this as a basis to disparage this stock is inconsequential. I'd encourage you to take a look at the big picture. If you are still not happy with the big picture, you always have the option to sell.
