US Stocks Rise on AI Optimism, Mideast Deal Hopes (Tuesday, August 4, 2026)

Market Wrap

U.S. stock markets saw a broad rally on Tuesday, August 4, 2026, with the S&P 500 reaching an intraday record high. The Dow Jones Industrial Average also hit a record high, building on momentum from the previous day's record close. All three major indexes—the S&P 500, Nasdaq, and Dow—advanced. The S&P 500's intraday record marked its first since early June.

On Monday, August 3, the Dow Industrials closed at a record high. That day, the Dow rose by 1.3%, the S&P 500 advanced by 1.5%, and the Nasdaq increased by 2.1%. The Russell 2000 also saw gains, rising by 1.94% on Monday.

What Drove It

The market's positive performance on Tuesday was primarily driven by two key factors: strong artificial intelligence (AI)-linked earnings reports and optimism surrounding a potential deal to de-escalate tensions in the Middle East.

Upbeat AI-driven forecasts from companies like Caterpillar and Palantir provided a significant boost to investor confidence. These reports followed recent strong earnings from other AI heavyweights such as Amazon and Microsoft, which had already reassured the market about the sector's robust growth. The sustained strength in AI-related earnings has been a consistent driver of recent gains on Wall Street.

Adding to the positive sentiment were hopes for an imminent deal to end tensions in the Middle East. Treasury Secretary Scott Bessent commented that a deal with Iran to reopen the Strait of Hormuz could materialize "today or tomorrow." This optimism contributed to the rally. However, there was some market skepticism that the U.S.-Iran conflict would be resolved quickly through diplomacy, as evidenced by a rebound in oil prices during the day. This contrasts with Monday's market action, where oil prices had fallen on initial hopes of easing U.S.-Iran tensions after U.S. President Donald Trump indicated talks with Iran to reopen the Strait of Hormuz were planned. Iran, however, disputed that talks were scheduled for Monday. Federal Reserve Governor John C. Williams also expressed optimism on Monday that inflation would ease, further supporting market sentiment.

Sector Highlights

Specific details on leading and lagging sectors for Tuesday were not provided in the sources. However, the strong performance of AI-linked companies suggests that the technology and industrial sectors, particularly those with significant AI exposure, likely performed well. Jefferies analysts favor technology and financial stocks.

Precious Metals & Commodities

Oil prices experienced a rebound on Tuesday, indicating lingering market skepticism about a rapid diplomatic resolution to the U.S.-Iran conflict. This stands in contrast to Monday, when crude prices settled down about 5% on hopes of de-escalating tensions.

On Monday, August 3, crude oil prices were $75.87, representing a decline of 5.56%. The S&P GSCI Index Spot, a broad commodities index, also fell by 2.43% to 652.46 on Monday. On Tuesday, however, crude oil prices rose by 0.80% to $80.98. The S&P GSCI Index Spot also saw a slight increase of 0.21% to 670.10.

Gold futures saw varied movement. On Monday, August 3, gold was priced at $4133.80, rising by 1.06%. On Tuesday, gold futures showed a gain of 0.49%, reaching $4110.40.

The U.S. Dollar Index (DXY) was largely stable. On Monday, it showed a slight decline of 0.05% to 96.14. On Tuesday, it edged up by 0.03% to 96.22.

The yield on the 10-year U.S. Treasury note was 4.625% on Monday, August 3, represented by a change of 26/32. On Tuesday, the 10-year yield was 4.698%, with a change of -2/32.

The Japanese Yen firmed on Monday after the U.S. and Japan confirmed joint intervention. On Tuesday, the Yen eased but retained most of its intervention-driven gains.

What to Watch Tomorrow

Investors will be looking for further developments regarding the U.S.-Iran talks, particularly following Treasury Secretary Bessent's remarks. Additionally, the focus will turn to the release of SpaceX's first quarterly report after the market closes on Tuesday, which will be a key event for investors.

Bottom Line

Tuesday's market rally underscored the continued influence of strong AI-related corporate earnings and optimism surrounding geopolitical de-escalation in the Middle East. While broader market indexes posted gains, the rebound in oil prices suggests that investors remain cautious regarding the swift resolution of international tensions. Long-term investors should continue to monitor corporate earnings reports, particularly from the technology sector, alongside global geopolitical developments for their potential impact on market stability.
