Wall Street set to open sharply higher as Brexit worries ease

Wall Street was set to open sharply higher on Monday after polls over the weekend showed an increased possibility of Britain remaining in the European Union. "Everyone is going to hold their breath until Thursday or Friday, when we get to know the result of the British referendum," said Adam Hewison, chief executive of Ino.com in Maryland. Barrick Gold and Newmont Mining were down about 3 percent each premarket.
