Stock Market Update
On June 26, 2026, traders were busy on the New York Stock Exchange floor during the morning session. Recently, however, stock prices took a dip as tensions flared between the U.S. and Iran, marking their first exchange of fire in a month. Still, the major indices are poised to finish August with overall gains.
The S&P 500 saw a decline of 0.4%, and the Nasdaq Composite mirrored this drop. Meanwhile, the Dow Jones Industrial Average fell by 346 points, or roughly 0.7%.
On Sunday, U.S. Central Command confirmed that there had been strikes on two rocket launchers located on Iran’s Larak Island. This attack marks the first U.S. operation against Iranian positions that’s been documented since late July. Iranian state media, in response, reported strikes on U.S. bases in Jordan.
Amid this renewed conflict, oil prices surged. U.S. West Texas Intermediate oil saw an increase of over 3%, rising above $86 per barrel, while Brent crude oil futures exceeded $91, also showing a gain of more than 3%.
Although the Middle East’s heightened tensions have caused some volatility in August, Wall Street appears to be ending the month on a favorable note, especially led by a strong tech sector. The Dow has risen more than 1% this month, aiming for its fifth consecutive month of gains. The S&P 500 and Nasdaq are also set to achieve their first monthly gains since May, with increases around 2% and 3%, respectively. Notably, both the S&P 500 and Dow reached all-time highs earlier this month.
Technology has been driving the upward momentum, particularly stocks linked to artificial intelligence. The S&P 500 tech sector has jumped nearly 6% throughout August. Nvidia has risen over 7%, while Microsoft and Micron Technology experienced even greater leaps of 9% and 14% respectively.
That said, August hasn’t been without its challenges. Inflation concerns led to Treasury yields reaching multi-year highs. The Treasury Department had tried to intervene by announcing increased debt repurchases, but the yields on longer-term bonds remain high. Federal Reserve Chairman Kevin Warsh expressed his concerns about inflation comments, emphasizing that recent data, while better than anticipated, does not indicate a significant improvement in underlying trends.
A Barclays economist, Jonathan Millar, noted the potential for a 25 basis point interest rate hike in September, which he thinks is now more likely. Investors will be looking for further economic insights this week, especially with the August jobs report set to come out on Friday. Additionally, manufacturing and services sector data will also be released.
As always, traders will be keeping an eye on events out of Asheville, North Carolina, where a meeting of the Group of 20 finance ministers is occurring.
