Ann: Director Share Purchase - David Williams, page-65

DW is a long term investor and knows what a good deal looks like.
IMO he is simply timing his buying for best effect against the short sellers while getting a great investment deal. If he triggers a squeeze - well and good. He knows the company will be profitable soon, does not need a cap raise and has a 90% gross margin with an effectively very long growth runway. I suspect his purchases over the last 2 years will not be sold for several years and will have multiplied tenfold at least.

He may stop buying today or keep going for a few more days or several more days. It doesn't really matter on the time frame this company will need to get to a long term investment success. I think any negative sentiment is transitory from most realistic investors.
What does matter is making the most of the opportunity the shorting has provided.

DW has taken a lot of shares off the cover table and a lot of holders are not selling any time soon and if they are it is will be small trading parcels. The rest of the covering will need to come from elsewhere and there is a limit to how many shares can be lent as ammunition to push down fiurther. There also a limit to any real short upside from here.
