Apple falls on profit warning, but Nvidia gains steady U.S. stocks

U.S. stocks traded mixed on Tuesday as Apple fell 3.4% on weaker profit margin guidance, while gains in other Big Tech stocks like Nvidia cushioned the broader market. The S&P 500 rose 0.2%, the Nasdaq gained 0.5%, and the Dow dropped 0.4%. Apple's decline followed its report of higher memory chip costs due to AI-driven demand, which it said would reduce profit per revenue dollar in the final quarter. Nvidia rose 3.1% and CoreWeave gained 2.6%, supporting the market, while Palantir fell 4.2% despite beating profit expectations. Midterm elections added uncertainty, though historical data shows the S&P 500 has risen in the six months after every midterm since 1970. Oil prices swung near $104 per barrel, and South Korea's Kospi dropped 3.6% on tech losses.
