The S&P 500 rose 0.6%, the Dow gained 0.7%, and the Nasdaq added 0.5% on Monday as investors positioned ahead of a heavy earnings and policy week. Gains were led by technology and communication services, with Apple up 3%, Meta 2.1%, and Microsoft 0.9% ahead of results later this week, while consumer discretionary lagged as Tesla fell 3.1%. Focus has shifted to Wednesday’s Federal Reserve decision amid speculation President Trump could name a new Fed Chair as soon as this week, alongside renewed shutdown risk after Democrats threatened to block a $1.2 trillion funding bill if it includes Homeland Security spending. Trade uncertainty lingered after Trump reiterated the threat of 100% tariffs on Canadian imports tied to a potential China deal, though Ottawa downplayed the risk. Safe haven flows pushed gold to record highs above $5,100 per ounce, reflecting elevated geopolitical and fiscal uncertainty even as earnings remain broadly supportive.
