Hey Gof! You sound like a former employee that missed becoming a millionaire like most of the folks that have worked at Regeneron for the last 5 years...As I have said since we were at 130, this IS the next Genentech!!!
Every piece of news regarding REGN right now is extremely positive. There is absolutely no reason I can see to think this is anywhere near the top. I do all my research and do not drink the cool aid on stocks. There is nothing to suggest this will go anywhere but UP for the foreseeable future .... IMHO
