TSX slips 0.5% at open as Nvidia turmoil weighs on tech

TORONTO – The S&P/TSX composite index was down 0.514 per cent in early trading Thursday, as questions about Nvidia’s chief executive weighed on artificial intelligence stocks and U.S. futures pointed lower.

The index stood at 36,224.73, down 186.99 points from Wednesday’s close of 36,411.72, as of 9:33 a.m. ET, according to TMX Money. The figures are intraday and will change through the session.

The Associated Press reported that Nvidia shares slid more than seven per cent to US$160.85 before the opening bell, about 34 per cent below the chipmaker’s all-time high reached just over a month ago. The New York Times reported Wednesday that CEO Jensen Huang had a second affair with an Nvidia executive who reports to him, and analysts quoted by the AP said that could force the board to remove him.

The AP said futures for the S&P 500 were down 0.4 per cent early Thursday and futures for the Dow Jones industrial average were nearly unchanged. In Europe, Germany’s DAX rose 1.0 per cent to 26,939.92 and Britain’s FTSE 100 gained 0.3 per cent to 10,868.98, while Japan’s Nikkei 225 fell 0.7 per cent and Hong Kong’s Hang Seng lost 1.3 per cent.

The pressure on the AI trade lands on a Toronto market that rose 0.667 per cent on Wednesday, when TMX Money showed the index up 14.817 per cent so far this year. Shopify Inc. (TSX:SHOP), the third-largest constituent of the index by market capitalization according to TMX Money, closed Wednesday at $207.97, down 2.164 per cent.

On the earnings calendar, Canadian Tire Corporation, Limited (TSX:CTC.A) reported third-quarter earnings per share of $4.27 before the open, and Brookfield Corporation (TSX:BN) reported a profit attributable to shareholders of US$1.31 billion, or 54 cents US per diluted share, according to The Canadian Press. Our Thursday preview has the full list of reports and data due, and our Wednesday close report has the sector detail from the last session.

Figures come from TMX Money as of 9:33 a.m. ET Thursday, Nov. 12, 2026, and from the Associated Press and The Canadian Press. A closing report follows after the 4 p.m. ET close.
