Market Wrap: Thursday, September 24, 2026 — S&P 500, Nasdaq & Dow Jones

Today's market session saw a mixed tone, with the S&P 500 and Nasdaq Composite ending flat, while the Dow Jones Industrial Average posted a slight decline. The broad-based nature of the moves suggests a cautious sentiment, with investors balancing optimism over the potential reopening of the Strait of Hormuz against rising Treasury yields and concerns over oil prices. The 10-year Treasury yield surged above 5.1%, reflecting heightened volatility in the bond market, which in turn influenced stock prices. The Dow's more pronounced decline underscores its sensitivity to interest rate movements, while the S&P 500 and Nasdaq Composite's relative stability indicate a degree of resilience, possibly supported by big tech stocks. The session also highlighted the impact of geopolitical developments, with the Nasdaq's improvement on U.S.-Iran news and the Dow's fall on Treasury yields and oil prices rising providing a mixed picture. Notable themes included the potential for a Hormuz deal to offset rising yields, the influence of oil prices on market sentiment, and the meeting between U.S. President Trump and Chinese President Xi, which could have broader implications for global markets. Additionally, the session saw a quantum breakthrough and Nvidia partnership announcement from IonQ, which could have a positive impact on the tech sector.
