The CEO recently hired has a career history of moving into companies for the sole purpose of selling them. If you do not understand ask your broker. He will be glad to share his knowlede with you. I understand that since you are short then you will have a childlike dread of such events.
I don't know if you made that up or what,
but there has been no insider activity at all, no buying or selling for over 6 months, no options flipping..nothing. Which is exactly what you'd expect from a company that wanted to be or is a takeover target. Any insider who does buying,selling or flipping while negotiations were occurring would suffer the extreme wrath of the SEC, and be charged with a federal offense.
What's astounding, is that the SEC has no record of any insider activity at all. Yet insiders own 16% of the float. But quite a few foreign ownership filings. One Director who joined recently (Dr. Yitzhak Peterburg) is also a Director for TEVA. Do they dabble in genetics like ROSG ?
