Goldman Sachs analyst Jason English added Simply Good Foods (SMPL) to Goldman's Americas Conviction List while keeping a Buy rating on the shares with a $34 price target. Since the company reported earnings on January 9, the stock is down 17% on concerns over missing consensus growth expectations, English tells investors in a research note. However, the selloff is overdone as the miss was not a sign of reduced demand but rather improved inventory management at key retailer, contends the analyst. English also reiterates a Buy rating on BellRing Brands (BRBR) with a $26 price target. He sees "strong investment appeal" in both stocks.
