Obviously there is no way for any of us to know for certain the Aruda's and lawyers have been selling but, how much would 16 million shares of Polymedix be worth today? If they indeed have been sellers, it has nothing to do with their faith in the company, management, or products. It is simply a function of reducing risk. The great part is that as they complete enough selling they will likely get more and more patient and allow progress to generate higher sales prices. I believe that may be happening already. I love the fact that this board has so many posters who are willing to share their expertise in varied fields.
As for those who are annoyed by previous share holders disparaging management, check the article I just posted on that board. Scary if true.
