The Fool has an article here that shows the top insider purchases last week. Among them was Oyo Geospace which is a MF Hidden Gems pick.
There is also high insider buying on Vertex Pharmaceuticals, which is a MF Rule Breakers recommendation:
"Such is the nature of biotech investing. Dilution persists till the promise of a blockbuster drug is either (a) fulfilled or (b) not. Investors will have to wait till at least 2010 for a definitive answer, according to company filings."
This may be a great entry point for this stock if you can wait 2-3 years for the payoff
