"ZGEN – The 2-month chart makes it look like someone knew something during July"
I agree! I was holding a position back then and, when it started to drop, I went with my instincts and sold out at $13. I later bought a small amount of calls but I have also unloaded these with a small profit. Something did not feel right with ZGEN's trading back then! In my usual conspiracy theory manner, I attributed it to hedgies and decided to stay out for a while and watch. I am glad I did...
How someone knew something is the question here because that someone had to have an inside track at the FDA, which brings me back to my conspiracy theory...LOL...
