Piper Jaffray analyst Peyton Green upgraded Bank of the Ozarks to Overweight citing valuation following the recent pullback in the shares. The stock dropped Wednesday after Carson Block of Muddy Waters presented the company as a short idea. The short-seller induced pullback leaves Bank of the Ozarks valued at a discount to peers, even though the bank produces higher returns and is projected to post much stronger earnings growth, Green tells investors in a research note. He believes Ozarks' loan growth will remain strong and keeps a $46 price target for the shares. The stock closed yesterday down 67c to $37.01.
