you're forgetting the private placement on March 30, 2017. Those shares are released on Monday.
The run-up happened around January/February. Someone that participated in the PP, shorted 800K-ish shares (which they do not have on hand to pay back until Monday - so that FINRA number just waits, regardless of the current price). Going forward, they will only hold the 60 cent US warrants as of Monday. They de-risked to zero on their shares and already made their profit. Warrants are gravy.
