However miniscule the shares sold and converted and/or converted and sold, I think all shareholders would agree that insuder buying is always better than insider selling. 

Now that we are not in a (Agora classic scapegoat) "blackout period" it would be nice to see some insiders buying on the open market. The idea that these executives don't have cash available, or Canadian cash available is beyond laughable.

The only reason I could see for not increasing their position size would be that they are shrewd businessmen. If they bought a block of shares through that juicy convertible debenture deal, why would they put up more cash for a lesser deal?

Well, investor confidence. We're buying, why can't they? We can see the effect of disposing of a few shares, wouldn't purchasing on the open market have almost the opposite effect?   

PS: I think we can all agree that the company also deserves huge respect for pivoting and making such monumental changes in the company, and also the share price. Huge kudos to them. As shareholders it can be difficult to not always want more. We see LWLG, and PYR and we think, why not us? The PTK story continues, hopefully more up and to the right.
