The Financial Post reports in its Thursday edition that one day of volatility has shaken Canada's stock market to the point that strategists may reconsider their benchmark targets for the entire year. A Bloomberg dispatch to the Post says that stock-market prognosticators on both sides of the border who did not incorporate U.S. President Donald Trump's tariffs into their outlooks will probably need to lower their year-end expectations for the S&P/TSX Composite Index and the S&P 500 Index. The S&P/TSX composite plunged 3.1 per cent at the open on Monday, before paring its loss to 1.1 per cent by close, led lower by industrial stocks with cross-border supply chains. And while news after the closing bell that U.S. tariffs on Canada would be paused 30 days eased the near-term risk, in the long run, the uncertainty lingers. The tariffs Mr. Trump planned are "much worse than the market expected," CIBC analyst Ian de Verteuil wrote, adding he expects to see a 5-per-cent correction in Canadian equities. That is smaller than others on Wall Street and on Toronto's Bay Street expect, including Jefferies analyst John Aiken, who sees an immediate 10-per-cent impact and a 20-per-cent decline for the index longer term.
