Obviously we don't know what the real reasons for an individual selling are ( some good points made ) however I find it quite disturbing , As his recent webcast seemed very upbeat and professional . I felt a certain amount of confidence when he spoke of the efforts in trial design . That said his selling leaves the door WIDE open for interpretation ( and not all good reasons come to mind ) , what real confidence comes with his departing shares ??? Time will tell , ( just felt a chill) ... Stock
