Shares of Pfizer (PFE) - Get Report posted gains on Thursday after the drugmaker was named a "top pick" at Credit Suisse following a meeting the analysts had with Pfizer's management team.

In a note to clients, Credit Suisse said its meeting with senior Pfizer executives boosted its confidence in both management and the prospects for new products.
