Wells Fargo analyst Brian Fitzgerald downgraded eBay to Market Perform from Outperform with an unchanged price target of $45. The company's slowing gross merchandise volume suggests stagnant or decreasing market share, Fitzgerald tells investors in a research note. Further, the analyst believes eBay's segment margins look lower than the activist investors are assuming in a breakup, which suggests to him "lower potential upside from the strategic review." Fitzgerald's sum-of-the-parts analysis lead him to believe that eBay shares are fairly valued. With that said, the company's 7.2% free cash flow and share buyback potentials limit downside risk on the stock, contends Fitzgerald.
