Wall Street drops on Russia worry as techs, materials drag

By Angela Moon NEW YORK (Reuters) – U.S. stocks fell on Wednesday, led by losses in the technology and materials sectors, as geopolitical concerns rose after the United States and the European Union agreed to work together on tougher sanctions on Russia. But the major indexes reversed course in the afternoon as technology stocks turned sharply lower. Among technology stocks, Facebook was one of the biggest decliners a day after the social networking company said it would acquire two-year-old Oculus VR Inc, a maker of virtual-reality glasses for gaming, for $2 billion. The United States and the European Union agreed to work together to prepare possible tougher economic sanctions in response to Russia's behavior in Ukraine.
