NEW YORK / RankWire.AI / – On Wednesday, U.S. equities closed higher, buoyed by a notable drop in long-term Treasury yields which supported market sentiment. The S&P 500 added 16.22 points, or 0.21%, finishing at 7,707.98. The Dow Jones Industrial Average increased by 119.65 points, or 0.22%, ending the session at 53,463.05. The Nasdaq Composite climbed 41.38 points, or 0.16%, to close at 26,331.09. This upward movement marked the end of a three-day losing streak for all three major U.S. indexes.
The session was largely influenced by bond market activity following the U.S. Treasury Department‘s announcement of increased liquidity support buybacks for longer-term debt. Starting September 9, the maximum purchase size will rise to at least $4 billion per operation from the previous $2 billion. This adjustment applies to nominal coupon securities with maturities in the 10-to-20-year and 20-to-30-year ranges. The department indicated that these larger purchases will continue through November 4, supported by strong volumes of high-quality offers.
Following the announcement, Treasury yields declined as bond prices moved upward. The benchmark 10-year yield fell 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 since 2007. The decline in yields eased some of the pressure from rising borrowing costs, which had previously weighed on equities. This shift also contributed to Wall Street’s recovery from earlier weekly losses.
Healthcare Sector Gains Provide Additional Support
Healthcare stocks gained ground after Moderna and Merck announced encouraging late-stage results from a melanoma study. Moderna shares surged by 177%, while Merck rose 12.6% during the trading session. The Phase 3 INTerpath-001 trial evaluated intismeran autogene combined with Keytruda after surgery for patients with high-risk melanoma. The trial met its primary endpoint related to recurrence-free survival and also achieved a key secondary endpoint measuring the absence of cancer spread to distant sites.
The consumer sector also experienced positive movement following earnings reports from several major companies. Estée Lauder’s shares jumped over 16% after its financial results were announced. Target and Lowe’s shares also increased after publishing their quarterly earnings. Smaller-cap stocks outperformed the large caps, with the Russell 2000 advancing about 0.5%. These gains helped broaden the market’s recovery beyond healthcare. Meanwhile, technology stocks showed mixed performance, limiting the overall gains of the major indexes.
Week-to-Date Performance Remains Slightly Negative
Despite Wednesday’s upward move, the principal U.S. stock indexes still showed weekly declines by the close. The Nasdaq was about 1.5% lower, the S&P 500 was roughly 1% below last Friday’s levels, and the Dow had declined approximately 0.5%. The rebound was driven by declines in long-term yields, which alleviated some of the valuation pressures and prompted a more cautious approach across major equity sectors.
All three major averages remained in positive territory for 2026 following Wednesday’s trading session. The S&P 500 had gained approximately 12.6% since the start of the year, the Dow had increased around 11.2%, and the Nasdaq was up about 13.3%. Wednesday’s gains reflected a modest recovery on Wall Street, fueled by lower Treasury yields and strong healthcare sector performance. The announcement from the U.S. Treasury Department and positive results from the melanoma trial were among the key market influences during the trading day.
