I have a legit concern that I'm hoping some of you

I have a legit concern that I'm hoping some of you longs can help me out with. Just so you all know I am not a basher. I rarely post on here and have been a long here since January 2017 and have doubled my position in the past month. Ok here goes, if owcp is so close to possible breakthrough safety results as they claim. Why would JF sell his shares earlier then what was warranted? Wouldn't he know the possible potential and want to hold his shares a little longer for bigger returns? By the way, I know there could a bunch of possibilities as to why he may have sold early but I would like to hear anyone's thoughts on this. Thanks ahead for any feedback.
