yet another bogus story about insider sale. Since they can not sale stock for during approval process, Insider need to plan sale after approval (or may be after bad news) otherwise they easily endup in jail.
Most insider get lot of options and little salary (Compare to option grant) and they normally spend lot of money. So no suprise they sale after approval.
I am sure they thinking it will be 17-18 atleast after approval.
Regarding fund that sold 2 milion share, They still own 10M+. Also they likely buy it at 7 or 8 and making good profit in short term. They might just thinking they have better oppturnity else where. it's no big deal. Investment company decision to sale have many reasons and most of them likely nothing to do fundamental.
