S&P 500 Hits Record High as Tech Rallies, Dow Drops 409 Points on Health Insurance Slump

The S&P 500 closed at a record high of 6,978.60 on January 27, 2026, gaining 0.41%, while the Nasdaq surged 0.91% on tech strength. The Dow Jones fell 409 points (0.83%) to 49,003.41, dragged by a healthcare sector collapse after UnitedHealth (UNH) plunged over 19% on weak 2026 revenue guidance. Health insurers Humana (HUM) and CVS Health (CVS) crashed 21% and 14%, respectively, following proposed Medicare Advantage rate changes. Tech outperformed as Micron (MU) rose over 5% on a $24 billion Singapore investment plan. Markets await Fed's January 28 policy decision, expecting rates to hold at 3.5%-3.75%, with focus on future cut signals. Upcoming earnings from Meta, Microsoft, and Tesla on January 28, and Apple on January 29, are key for AI investment sentiment. Consumer confidence hit a 2014 low, reflecting trade policy concerns, while EU-India trade deal added geopolitical nuance.
