it was an automatic sell trade... nothing to do about even if good or bad news is comming. At the other hand Takeda has none insiders holding. Maybe the deal is AFFY is also not allowed. Look what happend in the past at Takeda with insider buying.
Are the dislikes because the information is false or because the information itself is 'disliked.' If it's a fact, then it's a fact.... I don't like it either as am long, but I'm not going to ignore it because the last time it happened, bad news was released and the pps dropped significantly. I'M JUST SAYING PEOPLE. ANY THOUGHTS!?
Your premise seems to be that he's getting out because he knows more than we do and so wants to dump everything he has, and we should follow suit. But he's a corporate insider, so he's not allowed to trade on nonpublic inside info. This suggests that even if he did decide to exit, he did so knowing no more than a meticulous investor knows, he's just evaluating it negataiely. You coud argue he as a director has a particularly good handle on the AFFY facts, but the point is that his sale is not a clue to some decision that's already been made and not announced or some development we don't already know.
