The Globe and Mail reports in its Tuesday edition that the S&P 500 fell to snap its longest streak of gains in 20 years on Monday as investors assessed U.S. President Donald Trump's latest tariff announcement ahead of the Federal Reserve's monetary policy decision later this week. A Reuters dispatch to The Globe says Canada's main stock index also fell, with a drop in oil prices weighing on energy shares. On Sunday, Mr. Trump announced a 100-per-cent tariff on movies produced outside the U.S. He provided no details on how such levies would be implemented. Several movie and television stocks fell sharply right after Mr. Trump's announcement, but later pared losses. "Nine up days in the S&P 500 is hard to maintain," said Art Hogan at B Riley Wealth in Boston. "We are starting to price in that eventuality of deals being announced, but we're running out of daylight on that because every week that goes by that we don't start cutting deals we're doing economic damage." The S&P/TSX Composite Index ended at 24,953.52, down 77.99. Data showed Canada's services economy contracted for a fifth straight month in April. Toronto's energy sector fell, with price of oil settling 2 per cent lower at $57.13 (U.S.) a barrel.
