US-Canada trade talks collapse, Dow futures dip as investors eye Fed and Nvidia earnings.

US-Canada trade negotiations broke down over the weekend, leading to new US tariffs on Canadian goods and Canadian retaliation threats. This escalated trade tension caused Dow futures to slip 0.1%, with tech stocks under pressure. Investors are also focused on the upcoming Federal Reserve Jackson Hole meeting for clues on interest rates, Treasury Secretary Scott Bessent's expected fiscal plan, and major tech earnings from Nvidia and others. The week promises significant market-moving events amid geopolitical and economic uncertainties.
