US Equities Defy Treasury Rout as Tech Leads Rally
U.S. equity markets extended their upward trajectory, with the S&P 500 Index climbing 1.8% to close at 5,420.3 on September 25, 2026, securing its third consecutive weekly advance. This robust performance unfolded even as the U.S. Treasury market experienced a sharp sell-off, pushing benchmark yields to multi-month highs.
The Dow Jones Industrial Average also registered a notable gain of 1.5% for the week, ending at 39,215.7, while the technology-heavy Nasdaq Composite outperformed, surging 2.2% to 17,890.1. Investor sentiment appeared to prioritize strong corporate earnings outlooks and continued enthusiasm for artificial intelligence advancements, largely shrugging off the rising cost of borrowing.
Market Impact
The Treasury market's significant repricing saw the yield on the benchmark 10-year note jump 15 basis points over the week, settling at 4.88%, its highest close since March 2026. The 30-year Treasury yield also surged, adding 12 basis points to reach 5.01%. This move reflected increasing investor concerns over persistent inflation and the potential for the Federal Reserve to maintain higher interest rates for an extended period, leading to a decline in bond prices across the curve.
This divergence between a rising equity market and a falling bond market represents the largest weekly disconnect since January 2025, highlighting a unique phase in market dynamics. Typically, higher bond yields can pressure equity valuations by making future earnings less attractive and increasing borrowing costs for corporations. However, the current rally suggests that robust earnings growth, particularly within the technology sector, is providing a strong counterbalance.
Alibaba Group Holding Ltd. ($BABA) shares experienced a pronounced decline, falling 7.2% to $78.15 for the week, erasing approximately $15 billion from its market capitalization. This slump was attributed to renewed speculation regarding tighter regulatory scrutiny in China's e-commerce sector and intensifying domestic competition. The decline in $BABA also weighed on the broader Chinese tech sector, with the KraneShares CSI China Internet ETF ($KWEB) dropping 4.5% over the same period.
What Analysts Are Saying
"The equity market's resilience in the face of rising yields underscores the underlying strength of corporate fundamentals, especially in sectors benefiting from secular growth trends like AI," noted Michael Wilson, Chief U.S. Equity Strategist at Morgan Stanley. "Investors are increasingly focused on earnings per share growth, which continues to surprise to the upside, rather than solely on the discount rate provided by Treasuries."
Conversely, analysts at Bank of America Global Research expressed caution, highlighting the potential for bond market volatility to eventually spill over into equities. "While equities have shown remarkable fortitude this week, the bond market's message of persistent inflation and higher-for-longer rates cannot be ignored indefinitely," stated Savita Subramanian, Head of U.S. Equity & Quantitative Strategy. "A sustained move above 5% on the 10-year Treasury could trigger a re-evaluation of risk premiums across asset classes, potentially leading to a sharp correction in growth stocks."
Regarding Alibaba, "The recent decline in $BABA reflects a confluence of factors, including a challenging macroeconomic environment in China, fierce competition from peers like PDD Holdings ($PDD), and an ever-present overhang of regulatory risk," said Alicia Yap, an analyst at Citigroup. "While valuations appear attractive, investor confidence remains fragile, awaiting clearer signals on consumption recovery and policy stability."
What to Watch
Investors will closely monitor the upcoming U.S. Personal Consumption Expenditures (PCE) price index report for September, scheduled for release on October 18, as it is the Federal Reserve's preferred inflation gauge. Any significant acceleration in core PCE could reinforce expectations for further rate hikes, potentially intensifying the bond sell-off and challenging equity valuations.
Key technical levels for the S&P 500 include immediate resistance at 5,450, a level it tested but failed to break through during Friday's session. A sustained breach above this point could open the path towards 5,500. Conversely, strong support is observed around 5,380, with a move below this potentially signaling a deeper pullback towards the 50-day moving average, currently near 5,320.
For Alibaba ($BABA), the market will be keenly watching its upcoming third-quarter earnings report, expected in early November, for insights into consumer spending trends and the impact of its strategic pivots. Furthermore, any official statements or policy directives from Beijing concerning the digital economy or anti-monopoly regulations could significantly influence the stock's trajectory. The 200-day moving average, currently around $82.50, presents a key resistance level for $BABA shares to reclaim.
