US stock market today: Dow slips as UnitedHealth rout offsets tech rally. S&P 500, Nasdaq hold near records. The U.S. stock market presented a tale of two tapes on Tuesday, January 27, 2026, as the Dow Jones Industrial Average (^DJI) bucked a broader market rally, sliding 334.77 points or 0.68% to 49,077.63. While the blue-chip index retreated, the S&P 500 (^GSPC) nudged closer to record territory, rising 0.21% to 6,965.10, and the tech-heavy Nasdaq Composite (^IXIC) surged 0.49% to 23,717.23. This divergence was fueled primarily by a massive 18.9% sell-off in UnitedHealth Group (UNH), which shed over $66 per share to trade at $285.08.
Investors are currently balancing a disappointing 0.09% Medicare Advantage payment hike for 2027—well below the 4% to 6% expected—against a landmark India-EU trade deal that promises to eliminate tariffs on over 90% of bilateral goods. Amidst this, the Federal Reserve began its first two-day policy meeting of 2026 with rates expected to hold at 3.50%-3.75%, while megacap tech optimism remains high as Meta, Microsoft, and Tesla prepare to report earnings on Wednesday.
Why the Dow is under pressure while the S&P 500 and Nasdaq rise
The Dow’s underperformance on Tuesday was almost entirely stock-specific. UnitedHealth reported quarterly earnings per share in line with expectations, but revenue came in slightly below forecasts. More importantly for investors, proposed Medicare Advantage payment rates for future years disappointed the market.
According to the Centers for Medicare & Medicaid Services, average payments are expected to rise by just 0.09% in 2027, far below what insurers had anticipated. That guidance triggered a broad selloff across health insurance stocks, but UnitedHealth bore the brunt. Its shares fell nearly 19% in early trade, erasing tens of billions of dollars in market value in a single session.
UnitedHealth also disclosed that a major cyberattack on its Change Healthcare unit last year reduced full-year revenue by roughly $799 million. While management reaffirmed long-term expectations and projected 2026 revenue above $439 billion, investors focused on margin pressure and regulatory uncertainty. The company’s medical care ratio rose to 89.1% in 2025, and even a modest improvement forecast for 2026 did little to calm nerves.
Because the Dow is price-weighted rather than market-cap weighted, a sharp fall in a high-priced stock like UnitedHealth can drag the entire index lower. The S&P 500 and Nasdaq, by contrast, are more diversified and currently dominated by technology leaders, allowing them to absorb weakness in healthcare more easily.
Tech optimism, earnings strength, and global trade signals
While healthcare weighed on blue chips, technology shares continued to attract buyers. Memory chipmakers advanced on expectations of sustained AI-driven demand, helping lift sentiment ahead of key earnings from the so-called “Magnificent Seven.” Results from Meta Platforms, Microsoft, and Tesla are due Wednesday, with Apple reporting later in the week. Investors are positioning for confirmation that corporate spending on AI infrastructure remains strong into 2026.
Cyclical stocks also added support. General Motors rose after reporting a fourth-quarter earnings beat, raising its dividend, and announcing a $6 billion share buyback. The automaker forecast adjusted EBIT of up to $15 billion in 2026 and signaled confidence in North American margins returning to the 8–10% range.
Airlines and transport names were mixed. American Airlines posted record quarterly revenue and offered an upbeat outlook despite missing earnings estimates, while United Parcel Service gained after forecasting higher 2026 revenue as it shifts toward higher-value shipments and reduces low-margin Amazon deliveries.
On the global stage, trade developments added another layer of complexity. The European Union announced a long-awaited trade agreement with India, a move widely seen as a strategic counterweight to U.S. tariff pressure. The deal comes as the Trump administration signals tougher trade measures, including a potential increase in tariffs on South Korean auto imports. Markets, already sensitized by recent geopolitical shocks, are watching closely for any escalation that could disrupt supply chains or global growth.
Federal Reserve meeting and political risks in focus
Investors are also closely tracking the Federal Reserve, which began its first policy meeting of the year on Tuesday. While policymakers are widely expected to hold interest rates steady, markets are eager for clues on when rate cuts could begin later in 2026. Any shift in tone could have outsized effects on equity valuations, particularly for growth stocks.
At the same time, political risk is back on the radar. A potential U.S. government shutdown is looming as Senate Democrats attempt to block a funding bill for the Department of Homeland Security. The standoff adds uncertainty at a moment when investors are already balancing earnings, rates, and global trade.
Top Stock Movers
The individual stock performance today is driven by a mix of breakthrough medical patents and massive institutional shifts in the healthcare sector.
- Nuwellis (NUWE) [+124.19%]: The undisputed leader of the day. The stock exploded following the issuance of a new U.S. patent for its pediatric blood filtration technology. This “low-float” micro-cap caught the eyes of day traders, triggering a massive volume surge of 79M shares.
- Intel (INTC) [+3.62%]: Intel is gaining traction as it kicks off global pre-orders for its 18A process chips. Investors are betting on this as the “Angstrom Advantage” that could reclaim market leadership from TSMC in the AI PC era.
- UnitedHealth (UNH) [-18.24%]: The Dow’s primary anchor today. UNH plummeted after the government proposed a mere 0.09% increase in Medicare Advantage payments for 2027. This regulatory “freeze” is a major blow to insurer profit margins, causing the stock to lose over $60 in a single session.
- American Airlines (AAL) [-3.26%]: Despite a record $14 billion in revenue, the stock dipped as it revealed a $325 million impact from the ongoing government shutdown, which has begun to affect flight operations and consumer bookings.
Gold and silver cool after record run
In commodities, oil prices edged higher. WTI crude rose close to 1% near $61 a barrel, while Brent crude traded above $64, supported by supply discipline and steady global demand. Precious metals cooled after historic highs. Gold eased below $5,070 after briefly touching fresh records, while silver dropped more than 5% as traders locked in profits following its explosive run. Natural gas fell sharply, pressured by mild weather forecasts and ample supply.
