NEW YORK / RankWire.AI / – U.S. stocks finished somewhat higher on Wednesday, buoyed by a sharp decline in long-term Treasury yields. The S&P 500 increased by 16.22 points, or 0.21%, closing at 7,707.98, breaking a three-day losing streak. The Dow Jones Industrial Average climbed 119.65 points, or 0.22%, to close at 53,463.05. The Nasdaq Composite added 41.38 points, or 0.16%, ending at 26,331.09. The drop in government bond yields helped the major indices recover after several sessions of pressure from rising borrowing costs.
Following the U.S. Treasury Department’s announcement of increased liquidity support buybacks for longer-dated government bonds, bond prices rose. From September 9, the maximum purchase size will go up from $2 billion to at least $4 billion per operation. This change applies to nominal coupon securities with maturities in the 10-to-20-year and 20-to-30-year ranges. These increased buyback amounts will be effective through November 4. The department explained that the decision was supported by strong volumes of high-quality offers, which justified expanding liquidity operations in those sectors.
As a result of the announcement, Treasury yields declined, reversing some of the recent upward trend in long-term borrowing costs. The 10-year Treasury yield dropped to approximately 4.65%, while the 30-year yield decreased to roughly 5.20%. On Tuesday, the 30-year yield had hit 5.337%, its highest level since 2007. Since bond yields move inversely to their prices, increased demand for government debt caused yields to fall. This retreat alleviated some of the pressure that had accompanied the recent selloff in longer-term government bonds.
Healthcare Sector Boosts Market Performance
The healthcare sector again contributed to the market’s positive momentum on Wednesday, with several pharmaceutical companies posting significant gains. Moderna shares surged by 177%, while Merck increased by 12.6% after both companies announced promising results from a Phase 3 melanoma trial. The INTerpath-001 study evaluated personalized mRNA therapy intismeran autogene combined with Keytruda following surgical removal of high-risk melanoma. The trial met its primary endpoint of recurrence-free survival, and also achieved a key secondary endpoint measuring survival without distant cancer spread.
This rally in healthcare stocks helped counterbalance mixed trading elsewhere, particularly within the technology sector. Consumer stocks also contributed, buoyed by several companies’ quarterly earnings reports released during the session. Estée Lauder shares rose over 16% following its earnings release, adding to gains among consumer-focused companies. Target and Lowe’s also saw gains after reporting their latest financial results. Smaller-cap stocks outperformed large-cap indexes generally, with the Russell 2000 up about 0.5% as the broader market rebounded.
Wall Street Reverses Three-Day Losing Streak
Wednesday’s gains marked the end of a three-session decline for the S&P 500, Dow, and Nasdaq. The recovery followed earlier losses driven by rising long-term yields earlier in the week. Despite Wednesday’s positive movement, the major indexes remained lower for the week at close. The S&P 500 was roughly 1% below last Friday’s level, while the Dow had dipped about 0.5% for the week. The Nasdaq was approximately 1.5% down, reflecting its weaker weekly performance.
Looking at the broader performance for 2026, the market trend stayed positive despite the recent dip and bond market pressures. By the close on Wednesday, the S&P 500 had gained around 12.6% since the start of the year. The Dow was up approximately 11.2% over the same period, while the Nasdaq led with a roughly 13.3% increase, highlighting its stronger year-to-date growth. Wednesday’s session thus represented a modest rally for Wall Street, supported by declining Treasury yields and healthcare sector gains, lifting all three major U.S. stock indices.
