The Globe and Mail reports in its Wednesday edition that the S&P 500 and Nasdaq fell on Tuesday as a rebound in technology shares faded and as President Donald Trump said the U.S. must react to Iran's shooting down of a U.S. helicopter. A Reuters dispatch to The Globe says the Toronto Stock Exchange also closed lower, with energy stocks weighing on the Canadian benchmark index as oil prices slid. Mr. Trump wrote in a social-media post that Iran had shot down the U.S. Apache helicopter that was patrolling the Strait of Hormuz overnight, and vowed to respond, which added to doubts about prospects for a truce in the Middle East war. The Cboe Volatility Index hit its highest level since April 7 during the session as stocks sold off. Technology stocks resumed Friday's sell-off after a bounce on Monday. The S&P 500 tech index fell more than 4 per cent before paring losses. The SE Semiconductor Index dropped as much as 8.6 per cent. S&P/TSX Composite Index ended down 67.05 points at 34,411.69, extending its pullback from a record closing high last Thursday. Celestica fell 4.1 per cent. The price of gold fell 1.6 per cent. U.S. consumer price data for May on Wednesday could offer fresh clues on energy prices.
