Sorry fredman, but I have to disagree with you on a few things. Seeing that the stock didn't bounce right back, all of those conspiracy theories can be laid to waste with a little DD. I did a 5 mins worth of digging and found this article: www.fool.com/investing/high-growth/2011/05/13/fda-advisory-panel-positive-shares-punished.aspx#commentsBoxAnchor
Here is an excerpt you might want to take note of:
Those insider buys are very tiny. Not the kind of insider buying you see right before things get better for a company. The CEO only added 13,000 shares to his now 898,912 share load. My calculator says that's barely a 1.5% increase in his holdings. The VP only bought $15K worth of shares himself. Again, nothing that sets off alarms on my scanner.
I trade FDA plays myself and don't see any reason to buy this stock other than to play the technicals bounce. With that being said, I do wish you the best of luck with it. Hopefully you bought the bottom and didn't hold all the way down from the top!
