VERT is controlled by a short position. The Buyer for Vert sent out morning bashers to try and get this down. They prob also sold some at the bid to drop this.
Vert may have caught wind of a pr that is coming tomorrow or is getting nervous with news pending at any moment. There now gonna start covering a big short position they took the rest of the day.
All Speculation by me. I am just creating conversation for the board.
