The Globe and Mail reports in its Tuesday edition that the S&P 500 and S&P/TSX composite indexes ended lower for a third straight session Monday after a day of wild swings in stock values, erroneous headlines and some of the biggest names on Wall Street voicing concerns about U.S. President Donald Trump's sweeping tariffs. The Globe's Darcy Keith writes that trading volume broke U.S. records for the second session in a row. All three major U.S. stock indexes, as well as the Toronto Stock Exchange, started the day sharply lower, with the Dow plunging as much as 1,700 points. But in late morning trading, stocks soared, with the Dow surging to a gain of nearly 900 points. The S&P 500, meanwhile, went from a loss of 4.7 per cent to a leap of 3.4 per cent, which would have been its biggest daily jump in years. The sudden rise followed a rumour, picked up by wire services and CNBC, that Mr. Trump was considering a 90-day pause on his tariffs. A White House account on X quickly labelled it as "fake news" and markets almost instantly reversed the rally. Shortly afterward, Mr. Trump dug in further and said he may raise tariffs more against China after it retaliated last week with its own tariffs on U.S. products.
