US Stock Futures Hold Steady as Iran Hormuz Deal and Earnings Shape Market Sentiment

U.S. stock index futures traded mostly flat on Wednesday evening as investors closely monitored developments surrounding a potential agreement to reopen the Strait of Hormuz while digesting mixed corporate earnings and preparing for key economic data later this week.

S&P 500 futures edged up 0.1% to 7,758.25, while Dow Jones futures gained 0.14% to 54,567. Nasdaq 100 futures slipped 0.17% to 29,564.25 after technology stocks lost momentum following a strong rally at the start of August.

Wall Street ended Wednesday on a mixed note. The Dow Jones Industrial Average reached another record high, but the S&P 500 closed 0.17% lower after retreating from earlier gains. The Nasdaq Composite underperformed, dropping 0.8% as investors sold technology shares. Chipmakers also weakened, with the Philadelphia Semiconductor Index falling 1.4%.

Market sentiment was weighed down by disappointing quarterly earnings from AMD and SpaceX, which triggered declines in both companies' shares. The pullback highlighted lingering concerns over the sustainability of high valuations across artificial intelligence and semiconductor stocks after significant volatility in recent months.

Investors are also keeping a close eye on geopolitical developments in the Middle East. Iranian officials indicated that an agreement with Oman to help restore shipping through the Strait of Hormuz is nearing completion. However, Tehran emphasized that it has not held direct talks with the United States and warned against further U.S. military action. Iran also cautioned that any agreement with Oman would not automatically guarantee security in the strategically important waterway.

Optimism surrounding the potential reopening of the Strait of Hormuz has pushed oil prices sharply lower this week while supporting broader risk appetite across global financial markets. Even so, traders remain cautious given the ongoing tensions between the United States and Iran, which have been marked by repeated military threats and diplomatic efforts since conflict escalated earlier this year.

Attention now shifts to Thursday's earnings reports from ConocoPhillips, Parker-Hannifin, Airbnb, and Warner Bros. Discovery. Investors are also awaiting Friday's U.S. nonfarm payrolls report for July, a key economic release that could influence expectations for future Federal Reserve interest rate decisions and set the tone for financial markets.
