NEW YORK / RankWire.AI / – On Wednesday, U.S. equities edged higher, supported by a notable decline in long-term Treasury yields. The S&P 500 added 16.22 points, or 0.21%, closing at 7,707.98. The Dow Jones Industrial Average increased by 119.65 points, or 0.22%, finishing at 53,463.05. Meanwhile, the Nasdaq Composite rose 41.38 points, or 0.16%, to end at 26,331.09. This upward movement ended a three-day losing streak for all three major U.S. indices.
The session’s primary driver was the bond market, following the U.S. Treasury Department’s announcement of increased liquidity support buybacks for longer-term debt. Starting September 9, the maximum purchase amount will rise from $2 billion to at least $4 billion per operation. The increase applies to nominal coupon securities in the 10-to-20-year and 20-to-30-year maturity ranges. The department indicated these larger buybacks would continue until November 4, following robust volumes of high-quality offers.
Following this announcement, Treasury yields declined as bond prices gained. The benchmark 10-year yield fell to approximately 4.65%, while the 30-year yield decreased to around 5.20%. Notably, the 30-year yield had reached 5.337% on Tuesday, its highest point since 2007. The drop in yields eased some of the pressure that rising borrowing costs had exerted on equities, contributing to Wall Street’s recovery from earlier losses this week.
Healthcare Sector Joins Rally with Positive Results
The healthcare sector contributed to the market’s strength as Moderna and Merck announced encouraging late-stage trial data for melanoma treatment. Moderna’s shares surged 177%, and Merck’s increased by 12.6% during the trading session. The Phase 3 INTerpath-001 trial evaluated intismeran autogene combined with Keytruda following surgery for patients with high-risk melanoma. The trial achieved its primary endpoint, demonstrating improved recurrence-free survival, and also met a key secondary endpoint related to metastasis-free survival.
Gains in consumer stocks also supported the upward trend, following strong quarterly earnings reports from major firms. Estée Lauder saw its shares jump over 16% after releasing its earnings. Shares of Target and Lowe’s also increased after reporting their latest financial results. Smaller-cap stocks outperformed their large-cap counterparts, with the Russell 2000 rising roughly 0.5%. These movements helped extend the market’s recovery beyond the healthcare sector. Technology stocks experienced mixed results, limiting the overall gains in the major indices.
Major Indices Still Weaker for the Week
Despite Wednesday’s rally, the three main U.S. stock indexes remained lower for the week at the close. The Nasdaq declined about 1.5%, the S&P 500 was roughly 1% below its previous Friday’s level, and the Dow was down approximately 0.5%. The rebound followed multiple sessions marked by rising long-term yields, which had weighed on stock valuations and prompted a more cautious approach among investors across various sectors.
Looking at the broader picture, the major averages remained firmly positive for 2026 after Wednesday’s close. The S&P 500 has gained approximately 12.6% since the start of the year, while the Dow is up about 11.2%, and the Nasdaq has increased around 13.3%. Wednesday’s session represented a modest recovery on Wall Street, driven by declining Treasury yields and strong healthcare sector performance. Among the key market influences during the day were the U.S. Treasury Department’s buyback announcement and the positive melanoma trial results, which helped lift stocks amid ongoing volatility.
