Google Stock Gains On Buy Upgrade

Shares of Google Inc. traded higher Wednesday following an upgrade to buy from hold at Pivotal Research. "We have been generally negative on Google since early 2013," said analyst Brian Wieser. But "the business has generally expanded better than we thought it would and margin erosion - while evidently worse than most investors expected - has not been quite as bad as we feared," he said. The bullish note comes a day after Google closed at a 14-month low following a price target cut at J.P. Morgan. Shares of Google edged up 1.7% to $506.74 in recent trade. Wieser backed his $610 price target.
