Major U.S. stock markets ended the day lower on Thursday, August 6, 2026, with the Dow Jones Industrial Average breaking its streak of all-time highs. The market pullback, which also affected the S&P 500 and the Nasdaq Composite, was driven by a combination of factors, including rising Treasury yields, rising oil prices and the digestion of new corporate earnings and labor market data.
US stock markets give ground amid volatility
The Dow Jones Industrial Average (DJI) posted a 0.9% decline, while the S&P 500 (GSPC) saw a 0.2% decline. The Nasdaq Composite (IXIC), in turn, presented a slight retraction of 0.1%. Investors showed caution in the face of rising borrowing costs and escalating geopolitical tensions, which directly influence commodities.
Impact of rising oil prices and rising bond yields
Global oil prices (BZ=F) rose to $83 per barrel, reflecting geopolitical uncertainty. Iran and Oman have announced talks for a temporary sea route through the Strait of Hormuz, a hotspot for oil shipping. This outlook, while it may indicate a solution, has not entirely dispelled concerns about the supply. Simultaneously, US Treasury bond yields have also increased, with the 30-year bond (TYX) reaching 5.21% and the 10-year bond (TNX) rising to 4.67%, which makes fixed income investments more attractive compared to stocks and puts pressure on the market.
Challenges and opportunities in the artificial intelligence scenario
The focus on investments in artificial intelligence (AI) remains intense, but the sector presents a mixed picture. High-performing AI companies such as Sandisk (SNDK) and Western Digital (WDC) saw their shares react negatively following their earnings release, reflecting concerns about high valuations and capital needs. In contrast, Microsoft (MSFT) celebrated a 43% increase in Azure revenue and more than 30 million paid licenses for its Copilot 365 software, showing that AI can significantly boost results for well-positioned companies.
Concerns about the artificial intelligence “bubble”
Analysts at Apollo Global note that the growth of investment in hyperscale infrastructure for AI is taking up a share of the Gross Domestic Product (GDP) at a faster pace than the telecommunications and real estate booms of the early 2000s. According to Torsten Sløk, an economist at Apollo Global, while the real estate boom grew 0.85 percentage points of GDP per year at its peak, the “AI cycle” develops at almost twice that speed. While promising, this accelerated pace raises the risk of an equally rapid downturn if demand for AI does not meet expectations, potentially leading to a severe macroeconomic impact.
Company performance and labor market scenario
Shares of other companies were also on the radar:
- Moderna (MRNA):It approved the first mRNA flu vaccine by the FDA, which boosted its shares.
- SpaceX (SPCX):Its shares showed volatility as the lockdown period ended, which allowed executives and early investors to sell their holdings, increasing the supply of shares in the market. Despite the post-IPO slump, retail investors continued to buy, showing confidence.
- ConocoPhillips (COP):It announced the retirement of its CEO, Ryan Lance, and the appointment of a successor, which was accompanied by a slight rise in the stock following its second-quarter earnings report.
In the job market, a report from Challenger, Gray & Christmas indicated that layoffs in July fell to their lowest level in two years. Data from the Bureau of Labor Statistics showed a slight increase in initial unemployment insurance claims, totaling 199,000 in the week ending Aug. 1. This data comes ahead of the July jobs report, which is eagerly awaited for Friday.
Copper and cobalt on the rise after African export ban
In a move with significant implications for the technology and energy industry, the Democratic Republic of Congo has imposed an immediate ban on the export of cobalt and copper concentrates. As the world’s largest supplier of cobalt (75% of global production) and the second largest of copper (13-15%), the measure aims to encourage domestic processing and increase the country’s revenue. The news sent copper and cobalt futures soaring, reflecting higher costs for these essential metals in batteries, electric cars and AI infrastructure.
Mortgage Rates and Expectations for Federal Reserve Decisions
Interest rates for U.S. mortgage loans have reached their highest levels in more than a year, with the average rate for a 30-year fixed-rate mortgage reaching 6.69% on August 5, 2026. This increase is directly linked to elevated government bond yields, which reflect investor concerns about the Federal Reserve’s commitment to controlling inflation. The monthly jobs report for July is expected to provide more clues about the central bank’s next monetary policy decision in September.
