U.S. stocks meandered to a mixed finish on Wednesday, August 5, 2026, hovering near record highs as markets weighed strong corporate earnings and ongoing uncertainty surrounding the U.S. conflict with Iran. The S&P 500 dipped 0.2% to 7,723.55, while the Dow Jones Industrial Average climbed 0.5% to reach another record at 54,349.12.
Wall Street’s uncertain trading session followed two days of significant gains that kicked off August on a strong footing. Several major technology companies slumped during the Wednesday session, weighing down broader indexes even as corporate earnings reports continued to impress AP News.
Wall Street Reaches New Highs Amid Tech Slump
The S&P 500 fell 12.97 points to close at 7,723.55, spending most of the day in positive territory after touching a record high on Tuesday. The tech-heavy Nasdaq Composite dropped 221.55 points, or 0.8%, to 26,363.44, pressured by declines among major technology shares including a 4% drop for Google parent Alphabet and a 1.1% decline for Microsoft.
Corporate earnings season has largely exceeded expectations so far. Three-quarters of the companies within the S&P 500 have reported results, with Wall Street anticipating overall profit growth of 50%. The Walt Disney Co. gained 3.6% after easily beating Wall Street’s profit forecasts, bolstered by theme park revenue and a $1 billion box office haul from “Toy Story 5.” Booking Holdings jumped 6.6% following a report that strong travel demand drove quarterly profit and revenue growth.
SpaceX Reports First Public Results and Shifts Chip Strategy
Elon Musk’s SpaceX fell 13.6% following the release late Tuesday of its first quarterly report as a public company, which revealed sharply increased spending on artificial intelligence infrastructure. Despite the stock drop, SpaceX provided a boost to semiconductor giant Nvidia by announcing it will exclusively use Nvidia chips for its artificial intelligence technology.
That exclusive agreement weighed heavily on Advanced Micro Devices, which saw its shares fall 7%. Musk had previously indicated that both SpaceX and Tesla would utilize chips from AMD alongside Nvidia hardware.
The broader artificial intelligence trade continues to dominate market discussions. Analysts note a distinct shift in investor sentiment regarding the technology sector.
Strait of Hormuz Uncertainty and Oil Price Volatility
Geopolitical tensions in the Middle East continued to cast a shadow over trading floors. The ongoing conflict involving the U.S. and Iran has stifled global oil supplies and rattled energy markets for five months.
President Donald Trump stated that a deal to reopen the Strait of Hormuz could materialize as early as Wednesday, though market participants remained cautious given numerous previous stops and starts in negotiations. Brent crude, the international standard, fell 0.1% to settle at $79.45 a barrel. Energy prices have experienced wild swings throughout the conflict, touching as high as $102 per barrel at peak periods and fueling stubbornly high inflation.
Additional escalation over the weekend involved continued U.S. strikes and retaliatory actions by Iran against U.S. allies in the region, particularly Kuwait, aol.com. Furthermore, Yemen’s Houthi militia declared a blockade against Saudi Arabian oil exports, while President Trump asserted that Iran will pay
for the deaths of U.S. military personnel.
