I am going to give you the benefit of the doubt, and consider you a smart man. I don't understand your perspective and am only asking so I can. What do you mean by "taking so much out"?? The amount that the insiders have sold is miniscule compared to whats out there. If thats a lot of shares to you then I am really confused.
Additionally, if insider trading is the only thing you use to rate a company then you probably are not too successful at trading. Asking why anyone would put money in this stock based on that alone is ignorant at best. Again, I am giving you the benefit of the doubt.
Answer me this one question, even if you ignore the rest.. and a simple Yes or No will suffice. Is all insider selling a bad thing?
