Healthcare, consumer stocks help Wall Street reverse course

Wall Street reversed course to trade higher on Wednesday, helped by healthcare and consumer discretionary stocks. "The selloff last week was an over reaction and the attempted rally was too fast and furious," said Art Hogan, chief market strategist at Wunderlich Equity Capital Markets. German Chancellor Angela Merkel said Brexit would have limited impact on the country's economy, while U.S. Federal Reserve Governor Daniel Tarullo said world financial markets are well prepared for the impact.
