Wall Street closed mixed on Tuesday, with the Dow Jones and S&P 500 posting gains, while the Nasdaq edged lower. Strong corporate earnings and falling oil prices boosted the market, but major tech stocks remained under pressure. The Dow Jones rose 529.85 points (1.02%) to 52,495.88, and the S&P 500 gained 21.84 points (0.28%) to 7,712.57. The Nasdaq slipped 6.06 points (-0.02%) to 26,424.81. Healthcare, industrial, and real estate sectors led gains, with the Russell 2000 up 1.7%. Equifax and Hasbro surged over 11% on better-than-expected results, and 3M also advanced. General Motors fell nearly 7% despite strong quarterly figures, as investors focused on the company's more cautious forward guidance.
