Stada turned out to be a covered stock,
Bain Capital und Cinven try to acquire it once again. The new offer price is set to €66.25 but now they need only 63% of shareholders agree.
Additionally, there are Hedge Fonds in the game.
Thus close position at €65.3
Though from rational point of view the price shall not exceed $66.25, there might be an irrational exuberance. Since this is a short position, better close.
