Missling just does not conduct himself like the usual CEO. He doesn't raise money the same way, he doesn't spend the same way, he uses late stage trials as research instruments more than anyone else, he doesn't communicate the same way, he doesn't seem to care much for deadlines, and he certainly doesn't try to manage the stock price the same way. He's a different animal.
So complaining that he isn't meeting the usual expectations for the usual CEOs is kind of silly. We should not make the usual inferences when he is not the usual actor.
