AstraZeneca shares fall as Pfizer walks away



    LONDON (Reuters) - Shares in AstraZeneca fell 2.4 percent in early trade on Tuesday after U.S. drugmaker Pfizer said it would not make a formal bid to acquire its smaller British rival.

    Societe Generale analyst Stephen McGarry downgraded the stock to "sell" from "hold" on the news, setting a price target of 36 pounds a share.
