Stocks turn unsteady following last week's sell-off, but oil prices fall sharply

U.S. stocks wavered Monday after last week’s sell-off, with traders reacting to sharp moves in oil prices and continuing questions around artificial intelligence spending. The S&P 500 edged up 0.1% and remained within 3% of its all-time high, while the Dow Jones rose 431 points, or 0.8%, and the Nasdaq fell 0.2%. Oil helped early gains: Brent fell 7.9% to $104.48 amid uncertainty over when a potential Iran conflict would let global production normalize. Big Tech stocks have also been volatile as investors weigh whether AI data-center investments will deliver enough profits; Alphabet rose 1.4%.
