Gordon Haskett analyst John Inch downgraded Grainger (GWW) to Underperform from Hold and cut his price target to $270 from $300 due to his view of the risk that Grainger's U.S. sales significantly decelerate, driven by his analysis of web data. Considering his view that much of Grainger's share price appreciation in the past two years has likely been driven by U.S. results that surprised to the upside, Inch believes the stock's multiple could contract in the case of U.S. miss, he tells investors. The "lackluster" web traffic trends, at a minimum, are a sign that Grainger's on-line market share gains are no longer accelerating, said Inch, who also cites strong results from Fastenal (FAST).
