NEW YORK / RankWire.AI / – On Wednesday, U.S. equities experienced moderate gains, buoyed by a significant decline in long-term Treasury yields. The S&P 500 increased by 16.22 points, or 0.21%, reaching 7,707.98 and ending a streak of three consecutive losing sessions. Meanwhile, the Dow Jones Industrial Average added 119.65 points, or 0.22%, closing at 53,463.05. The Nasdaq Composite also advanced, gaining 41.38 points, or 0.16%, to settle at 26,331.09. These gains were largely supported by the drop in government bond yields, which helped the major indices recover after several sessions of downward pressure caused by rising borrowing costs.
The boost in bond prices came after the U.S. Treasury Department announced an increase in liquidity support buybacks for longer-dated government bonds. Starting September 9, the maximum purchase amount will be raised from $2 billion to at least $4 billion per operation. This update applies to nominal coupon securities within the 10-to-20-year and 20-to-30-year maturity ranges. The expanded volume will be in effect through November 4. The department explained that strong demand for high-quality offers in these sectors motivated the decision to boost liquidity operations.
Following the announcement, Treasury yields moved downward, reversing some of the recent increases in long-term borrowing costs. The 10-year Treasury yield fell to approximately 4.65%, while the 30-year yield decreased to around 5.20%. Notably, the 30-year yield had touched 5.337% on Tuesday, marking its highest point since 2007. Since bond prices and yields move inversely, increased demand for government debt resulted in lower yields, alleviating some of the pressure that had built up during the recent selloff of longer-term bonds.
Healthcare Sector Contributes to Market Momentum
During Wednesday’s trading session, healthcare stocks played a key role in supporting the market’s overall positive movement, with several pharmaceutical companies posting substantial gains. Moderna shares skyrocketed by 177%, while Merck rose 12.6%, following the announcement of favorable results from a Phase 3 melanoma trial. The INTerpath-001 study evaluated a personalized mRNA therapy called intismeran autogene in combination with Keytruda after the surgical removal of high-risk melanoma. The trial successfully met its primary endpoint of recurrence-free survival and also achieved a key secondary endpoint related to survival without distant cancer spread.
This surge in healthcare stocks helped offset mixed performance elsewhere, particularly within certain parts of the technology sector. Consumer-related stocks also contributed to the positive sentiment after several major companies released quarterly earnings. Estée Lauder advanced more than 16% following its earnings report, boosting the broader consumer stocks. Target and Lowe’s also saw gains after reporting their latest financial results. Smaller-cap stocks outperformed their large-cap counterparts, with the Russell 2000 rising around 0.5% as the broader market regained strength.
Wall Street Breaks Three-Day Losing Streak
Wednesday’s gains marked the end of a three-session decline for the S&P 500, Dow, and Nasdaq. The rally followed earlier in the week when rising long-term yields exerted downward pressure on stocks. Despite Wednesday’s positive turn, the major indexes still closed lower for the week; the S&P 500 was roughly 1% below last Friday’s level, the Dow had fallen about 0.5%, and the Nasdaq was approximately 1.5% lower.
Looking at the broader 2026 outlook, the market still posted gains for the year despite the weekly decline and recent bond market turbulence. As of Wednesday’s close, the S&P 500 had increased about 12.6% since January 1, while the Dow was up roughly 11.2%, and the Nasdaq led with an approximate 13.3% rise, reflecting its stronger year-to-date performance. Wednesday’s session thus offered a modest recovery for Wall Street, supported by the decline in Treasury yields and positive movements in healthcare stocks, which collectively lifted all three major U.S. stock indexes.
