very "unusal activity" in the end. JB just sold 80 k according to filing on 05/06. Bankers know even before insiders whenever big pharma makes an offer. Money always need prior arrangement before any move could be made. VRTX is a big burger and pharma must be drooling. VX 787, VX509, CF and VX 135 with Daclatasvir, what else one need? I hope to see a buyout like VRUS, $69 ABOVE CLOSING PRICE!
When was the last time that you saw so many insiders unload before a merger or buyout was announced? There were almost a million shares sold off by insiders in the last few weeks. Almost 100K in the last week. I doubt they'd be so foolish. Good luck with that though.
