Markets edge up as US-Canada tariff row intensifies ahead of Jackson Hole

U.S. equities advanced modestly after a day of tariff-driven headlines, with the Dow up about 0.3%, the S&P 500 around 0.2%, and the Nasdaq roughly 0.6%, as Canada retaliated with duties in response to U.S. tariffs. Nvidia earnings and Fed Chair Jerome Warsh’s Jackson Hole speech loom large for market sentiment, while Bitcoin briefly topped $80,000 and oil slipped on tariff headlines. Economic data showed softer new-home sales and consumer confidence, setting a cautious tone ahead of the Fed symposium. DICK’S Sporting Goods fell about 13% after missing expectations and trimming its outlook, and Canada’s TSX rose on financials amid the broader volatility.
