Bank of America Merrill Lynch on Tuesday named Merck its top pick among the many U.S. pharmaceutical stocks thanks to the growing success of its key cancer drug, Keytruda.

"Merck looks well positioned to become the preferred PD1 agent in most major tumor markets, and we estimate upcoming data readouts in lung and renal cancer have the potential to add $4 billion in peak sales or 5 to 10 percent upside," Bank of America's Jason Gerberry wrote in a note to clients.
