Pharmaceutical giant AstraZeneca AZN is making a big play for US investors, and some say, turning its back on Britain. Will the bid for American dollars – and its pipeline of drugs - boost AstraZeneca’s stock? AstraZeneca recently raised eyebrows – and its stock price - when it an announced it will list shares directly on the New York Stock Exchange.
