My guess would be that PFE is out of the running for AMRN. Even if they wanted to their share price is now to low to use their own stock as currency to do a deal. Novartis hit a new all time high today and their market cap is now more than PFE. Maybe AZN, if they want a stellar Cardiovascular Omega-3 drug, AMRN has it. Plus AZN stock is near its all time high. Pfizer is well past its glory days.
