NEW YORK / RankWire.AI / – U.S. equities finished with modest increases on Wednesday amid a sharp decline in long-term Treasury yields. The S&P 500 gained 16.22 points, or 0.21%, closing at 7,707.98, breaking a three-day losing streak. The Dow Jones Industrial Average added 119.65 points, or 0.22%, to close at 53,463.05. The Nasdaq Composite rose by 41.38 points, or 0.16%, ending at 26,331.09. The decline in government bond yields helped major indices recover after recent pressure from climbing borrowing costs.
Bond prices increased following the U.S. Treasury Department’s announcement of larger liquidity support buybacks for longer-dated government debt. From September 9, the maximum purchase amount will rise from $2 billion to a minimum of $4 billion per operation. This adjustment applies to nominal coupon securities in the 10-to-20-year and 20-to-30-year maturity brackets. The expanded purchase volume will be maintained through November 4. The department stated that a strong flow of high-quality offers justified the decision to escalate liquidity operations in these sectors.
Following the announcement, Treasury yields decreased, 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 fell to about 5.20%. Tuesday saw the 30-year yield reach 5.337%, its highest since 2007. Bond yields tend to move inversely to prices, so increased demand for government bonds pushed yields lower. This retreat alleviated some of the pressure seen during the recent selloff in longer-term government securities.
Healthcare Sector Boosts Market Sentiment
Wednesday’s trading was supported by the healthcare sector, as several pharmaceutical companies reported significant gains. Moderna shares soared by 177%, while Merck advanced 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 achieved its primary endpoint of recurrence-free survival and also met a key secondary measure related to survival without distant metastasis.
The rally in healthcare stocks helped offset mixed performance elsewhere, especially within the technology sector. Consumer stocks also contributed as several leading firms released quarterly earnings reports. Estée Lauder rose more than 16% following its earnings release, boosting the gains among consumer-focused equities. Target and Lowe’s also moved higher after reporting their latest financial results. Smaller-cap stocks outperformed their larger counterparts, with the Russell 2000 gaining roughly 0.5% as the broader market rebounded.
Major Indices End Three-Day Losing Streak
Wednesday’s gains marked the end of a three-session slide for the S&P 500, Dow, and Nasdaq. This rebound followed earlier declines caused by rising long-term yields. Despite the positive session, the main indices still closed lower for the week. The S&P 500 was about 1% below last Friday’s level. The Dow decreased approximately 0.5% for the week, while the Nasdaq was roughly 1.5% lower overall.
Looking at the broader 2026 outlook, the market remains in positive territory despite recent setbacks and bond market pressures. As of Wednesday’s close, the S&P 500 had gained about 12.6% since the start of the year. The Dow had increased roughly 11.2% over the same period, with the Nasdaq outperforming at approximately 13.3%, reflecting its stronger year-to-date gain. Wednesday’s session provided a modest recovery for Wall Street, driven by declining Treasury yields and advances in healthcare stocks, lifting all three major U.S. stock indexes.
