In her research note, Merrill Lynch analyst Lauren Rich Fine attributed the upgrade primarily to stronger indicators for Yahoo!'s ad pricing. "This revenue estimate was based on increasing our estimate of cost-per-click sequential growth from 4 percent to 11 percent and our CPM year-over-year growth from 17 percent to 20 percent," she wrote.
Despite the upgrade, the Wall Street firm left it's "neutral" rating for Yahoo!'s stock due to its relatively high market valuation.
