Stocks end mixed as crude oil prices rise and stay over $100 a barrel

U.S. stocks closed mixed Monday while crude oil prices remained above $100 per barrel, signaling uncertainty across financial markets at the start of the week. Oil's sustained elevation above the $100 threshold typically weighs on consumer spending and corporate profits, as higher energy costs ripple through the economy. The mixed stock performance reflects investor caution about inflation pressures and economic growth prospects tied to persistently high fuel prices. Energy sector gains from elevated oil prices can be offset by weakness in consumer discretionary and industrial stocks that face margin pressure from rising input costs. The divergent market moves suggest traders are reassessing exposure to different sectors based on how they'll weather sustained higher energy costs.
