TSX falls as trade jitters continue

Canada's main stock index closed lower on Monday, tracking U.S. markets after U.S. President Donald Trump announced fresh tariffs against Japan and South Korea, sparking trade jitters among Canadian investors.

The benchmark S&P/TSX composite index TSX closed down 15.88 points, or 0.06%, at 27,020.28.

The TSX turned lower earlier in the day while investors awaited updates on trade developments. The index had posted fresh all-time highs every day last week and touched another record high on Monday before turning red.

Wall Street's major indexes closed lower after Trump's tariff announcements.

"It's more just a warning that these are friendly countries that are getting to the tariffs, and that's probably a reminder that Canada is not out of the woods yet," said Greg Taylor, chief investment officer at PenderFund Capital Management.

"We're starting to see that the tariff (worries) haven't gone away yet fully, that there's still going to be uncertainty around earnings. Investors are saying, 'Well, we've had such big gains. Why don't we hit pause and take some profits?'"
