NEW YORK / RankWire.AI / – On Wednesday, U.S. equities experienced modest increases amid a sharp decline in long-term Treasury yields. The S&P 500 added 16.22 points, or 0.21%, closing at 7,707.98 and ending a streak of three consecutive losing sessions. The Dow Jones Industrial Average rose 119.65 points, or 0.22%, finishing at 53,463.05. The Nasdaq Composite increased by 41.38 points, or 0.16%, to close at 26,331.09. The decline in government bond yields helped major indices recover after several sessions of downward pressure caused by rising borrowing costs.
Bond prices climbed following the U.S. Treasury Department’s announcement of larger liquidity support buybacks for longer-dated government securities. Starting September 9, the maximum purchase amount will increase from $2 billion to a minimum of $4 billion per operation. This adjustment applies to nominal coupon securities with maturities in the 10-to-20-year and 20-to-30-year ranges. The elevated purchase volumes will be maintained through November 4. The department explained that the decision was driven by strong demand for high-quality offers, which supported the move to expand liquidity operations in these sectors.
Following the announcement, Treasury yields moved downward, partially reversing the recent rise in long-term borrowing costs. The 10-year Treasury yield dropped to approximately 4.65%, while the 30-year yield decreased to around 5.20%. On Tuesday, the 30-year yield reached 5.337%, its highest level since 2007. Since bond yields move inversely to prices, increased demand for government debt caused yields to decline. This retreat eased some of the pressure that had emerged during the recent selloff in longer-term bonds.
Healthcare Sector Drives Market Rally on Wednesday
Healthcare stocks provided additional support during Wednesday’s trading session, with several pharmaceutical companies posting significant gains. Moderna shares surged by 177%, and Merck advanced 12.6% after both firms announced positive results from a Phase 3 melanoma trial. The INTerpath-001 study 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 counterbalance mixed trading elsewhere, especially within parts of the technology sector. Consumer-related equities also contributed to the positive tone after several leading companies reported quarterly earnings during the day. Estée Lauder’s shares jumped over 16% following its earnings release, boosting the overall consumer stocks’ performance. Additionally, Target and Lowe’s saw gains after releasing their latest financial results. Smaller-cap stocks outperformed large caps generally, with the Russell 2000 increasing about 0.5% as the broader market recovered.
Major Market Indices End Three-Day Downturn
Wednesday’s rally brought an end to three consecutive days of declines for the S&P 500, Dow, and Nasdaq. The recovery followed earlier sessions where higher long-term yields had negatively impacted equities. Despite Wednesday’s gains, the main indexes remained lower for the week. The S&P 500 was roughly 1% below last Friday’s close. The Dow declined about 0.5% for the week, and the Nasdaq was approximately 1.5% lower.
The overall performance for 2026 remained positive, despite the weekly decline and recent bond market pressures. As of Wednesday’s close, the S&P 500 had gained approximately 12.6% since the start of the year. The Dow had increased about 11.2% over the same period. The Nasdaq maintained a lead of roughly 13.3%, reflecting its stronger year-to-date growth. Wednesday’s session marked a modest rebound for Wall Street, supported by lower Treasury yields and gains in the healthcare sector, lifting all three major U.S. stock indices.
