Pivotal Research initiated coverage of Amazon.com with a Buy rating and $260 price target. Amazon has a “deep moat” around its core businesses driven by “unmatched scale” and has what appears to be the largest organic revenue growth opportunity of any mega cap tech company, driven by the Web Services segment, the analyst tells investors in a research note. The firm sees “continued rapid growth” in the company’s advertising business. Amazon also has the highest potential of its peers to materially boost operating margins driven by scale, leveraging robotics and benefits from an increasing percent of revenue from high margin cloud computing, contends Pivotal.
