I don't know Andrea. I find it hard to believe that Sheldon and his people with all their power don't know anymore then us. I mean it's just not the business way. It never works like that whether it's intentional or not. That's the reason we follow insiders as closely as possible.
Anyway, that's the way I see it. Maybe it's because I never trust anyone in the stockmarket (but you can trust there actions and judge how to react accordingly) and I don't think anyone else should trust anyone in the stockmarket either and I have good reason and experience for what I say. But you learn and make your bets around that.
