Argus analyst Stephen Biggar upgraded SunTrust to Buy from Hold with a price target of $57 after the Federal Reserve CCAR review, leading to a 25% dividend increase and a $2B stock buyback. Biggar also cites his expectations for the bank to expand its net interest margins and the underperformance for the stock relative to the regional bank index over the past 3 and 6 month periods, creating an "attractive entry point". Based on the company's strong credit quality, the analyst contends that it should trade at a slight premium compared to peers' average for PE and price to book multiples.
