Just noise. Mylan is very litigious. It is their strategy. CELG has no obligation to sell their drugs to Mylan and their drugs are on patent for several more years. This is typical Mylan strategy from what I've read. The REMS has been upheld by courts so this will go nowhere for Mylan and then CELG will be loved once again. All the funds that sold low will buy back high as they always do.
All, I have now said this on a number of boards in this space. This is noise. This stock is down as the entire bio tech space is getting crushed today. Shoot the market overall is getting battered... Sure, the shorts will toss fuel on the fire and try to create panic to improve the odds but to not listen. The fundamentals are great and this is a chance to add to a position and think a bit longer than "today".... Be smart. ;)
