The Globe and Mail reports in its Thursday edition that U.S. stocks ended little changed on Wednesday as investors digested the impact of two conflicting sets of jobs data and a report that said president-elect Donald Trump was mulling a national economic emergency declaration on inflation. A Reuters dispatch to The Globe says market sentiment was fragile after a CNN report said Mr. Trump was mulling building the new tariff program by using the International Economic Emergency Powers Act, which authorizes a president to manage imports during a national emergency. Ahead of Mr. Trump taking office later in the month, concerns about potential surcharges on U.S. trade partners have kept investors on edge as Mr. Trump's policies, including mass deportations and tariffs, could stoke inflation pressures. "There is quite a bit of caution in the markets with all the policy uncertainty that we're facing," said Douglas Porter, chief economist at BMO Capital Markets. "Incoming President Trump is quite serious about imposing tariffs on Canada in a meaningful fashion and that's clearly a negative for the Canadian economy and could weigh pretty heavily on the TSX." The S&P/TSX Composite Index ended up 121.79 points at 25,051.68.
