NEW YORK / RankWire.AI / – U.S. equities finished with modest gains on Wednesday amid a notable drop 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. Meanwhile, the Dow Jones Industrial Average gained 119.65 points, or 0.22%, ending the session at 53,463.05. The Nasdaq Composite added 41.38 points, or 0.16%, finishing at 26,331.09. The decline in government bond yields helped the major indices rebound after several sessions pressured by rising borrowing costs.

Bond prices rose following the U.S. Treasury Department’s announcement of increased liquidity support through expanded buybacks of longer-dated government debt. Effective from September 9, the maximum purchase size will increase from $2 billion to at least $4 billion per operation. The adjustment applies to nominal coupon securities within the 10-to-20-year and 20-to-30-year maturity ranges. These larger volumes will remain in effect until November 4. The department attributed the decision to the strong volumes of high-quality offers, which supported the move to expand liquidity operations in those sectors.
Following this announcement, Treasury yields decreased, reversing some of the recent upward trend in long-term borrowing costs. The 10-year Treasury yield dropped to around 4.65%, while the 30-year yield fell to approximately 5.20%. Notably, the 30-year yield had hit 5.337% on Tuesday, its highest level since 2007. Since bond yields move inversely to prices, the increased demand for government debt pushed yields lower, easing the pressure that had built up during the recent selloff in longer-term bonds.
Healthcare Sector Boosts Market Sentiment
The healthcare industry contributed to the positive momentum during Wednesday’s trading session, with several pharmaceutical companies experiencing significant gains. Moderna’s shares surged by 177%, while Merck’s stock rose by 12.6% following the release of encouraging results from a Phase 3 melanoma trial. The study, INTerpath-001, evaluated personalized mRNA therapy intismeran autogene combined with Keytruda after surgical removal of high-risk melanoma. The trial met its primary endpoint for recurrence-free survival, and also achieved a key secondary endpoint measuring survival without distant cancer spread.
This rally in healthcare stocks helped offset mixed performance in other sectors, especially within technology. Consumer-related equities also contributed as several major companies announced quarterly earnings during the session. Estée Lauder saw its shares jump more than 16% following its earnings report, adding to the gains seen among consumer stocks. Additionally, Target and Lowe’s experienced upward movement after releasing their latest financial results. Smaller companies generally outperformed their larger-cap counterparts, with the Russell 2000 index gaining about 0.5% as broader market sentiment improved.
Wall Street Ends Three-Day Losing Run
Wednesday’s upward movement marked the end of a three-session decline for the S&P 500, Dow, and Nasdaq. The rebound followed a period of pressure caused by rising long-term yields earlier in the week. Despite the gains, the main indexes are still lower for the week overall. The S&P 500 is roughly 1% below last Friday’s level, the Dow has declined about 0.5%, and the Nasdaq remains approximately 1.5% lower than the previous week’s close.
Looking at the broader performance for 2026, the overall trend remains positive, even with this week’s dip and recent bond market volatility. As of Wednesday’s close, the S&P 500 has gained roughly 12.6% year-to-date. The Dow has increased by approximately 11.2%, while the Nasdaq leads with a 13.3% rise, reflecting its stronger year-to-date performance. Wednesday’s session thus provided a modest recovery for Wall Street, supported by falling Treasury yields and healthcare sector gains, which helped lift all three major U.S. stock indexes.
