Despite investigations into the composition of its key drug, Acthar gel, as well as into its marketing practices, Questcor Pharmaceuticals (UNKNOWN:QCOR.DL) has announced that it is being bought by Mallinckrodt (NYSE:MNK) for $5.6 billion. Short-sellers have been attacking Questcor relentlessly recently, alleging that the stock could, in fact, be worth nothing if Acthar's composition is found not to be what the company claims.

He also tells Questcor bulls everywhere that this signals the end of the battle for Questcor investors, and that they've officially won the fight on this stock over the bears.
