RE: Solid MoveWestwind has bought 1,057,000 shares nearly all in Feb and have sold only 12,500 (on Feb 21). 100,000 of that was bought on Feb 27 at $0.66. They are by far the biggest buyer in Feb. They neither bought or sold any in the prior month (Dec 24 - Jan 24).
Yes it does look as if they are building a significant position.
For comparison the next biggest buyer Jan 24 - Feb 23 wass RBC with a net 250,000 buy.
