That would be the case for Gillman, but not for Eberwein. Eberwein has nothing to do with Boston Avenue Capital.
And Boston Avenue Capital looks like a family office, single family entity (based on Linked In description). So that is pretty darn close to true insider buying, don't try to discredit it.
You may be right regarding Eberwein - though I believe that the Form 4s are basically double counting everything. Every day when one is filed for Eberwein and another for Gillman, I believe they represent the same shares owned by Eberwein. If you look at the Form 4s, they are identical with regard to number of shares purchased, the average purchase price, the number of shares owned. Only difference is that Eberwein's shares are direct whereas Gillman is indirect. It may be the case that Eberwein's shares are held at Boston Avenue Capital and because Gillman is also a director he has to report indirect ownership on behalf of the firm?
