U.S. equities closed sharply higher on Tuesday, with the Dow Jones Industrial Average and the S&P 500 both setting new record highs. The rally was powered by a broadening artificial intelligence trade that extended beyond chipmakers, along with a steep drop in oil prices that eased inflation concerns.
The Dow climbed 1.88% to 54,175.70, while the S&P 500 added 1.90% to 7,744.97. The Nasdaq Composite outperformed, jumping 2.69% to 26,610.62, as semiconductor stocks rebounded. The gains came as investors digested a fresh wave of earnings reports and signs that AI-related spending is translating into revenue across multiple sectors.
AI Rally Broadens Beyond Chips
The market's advance was notable for its breadth. While chipmakers led the charge—the Philadelphia Semiconductor Index surged nearly 7%—software and industrial companies also posted strong gains. Palantir Technologies (NASDAQ:PLTR) jumped almost 30% after raising its full-year revenue outlook, while Caterpillar (NYSE:CAT) rose roughly 6% on robust demand for power-generation equipment used in data centers. Caterpillar alone contributed more than 300 points to the Dow's 998-point gain.
Investors are increasingly seeing evidence that AI capital expenditures are translating into earnings across the entire ecosystem, not just for cloud providers. The S&P 500 technology sector climbed 4.5%, roughly 2.4 times the index's overall gain, while Palantir's move was nearly 16 times the S&P 500's rise.
Earnings Season Exceeds Expectations
Underlying the rally was a strong earnings season. According to LSEG data, 85.2% of S&P 500 companies that have reported so far beat second-quarter forecasts—17.7 percentage points above the historical average. Caterpillar reported quarterly sales and revenue of $20.5 billion, up 24% year over year, with adjusted earnings of $8.17 per share. CEO Joe Creed noted, "Strong order rates and a growing backlog reflect broadening momentum across all three of our primary segments."
Oil Prices Tumble on Iran Talks
Oil was the second major driver of the rally. Brent crude fell 5.3% to $79.36 a barrel, while U.S. crude dropped 5.7% to $75.77, both closing at three-week lows. The decline followed reports of progress in U.S.-Iran negotiations, which could increase global supply. Lower energy prices helped temper inflation expectations and contributed to a pullback in Treasury yields.
Economic data remained relatively steady. Job openings in June were 7.4 million, roughly unchanged from the prior month, while hires held at 5.3 million and layoffs remained low at 1.8 million. The labor market's stability, combined with easing oil prices, bolstered confidence that the Federal Reserve may have room to consider rate cuts later this year.
Market Breadth and Investor Sentiment
Market breadth was solid, with advancing stocks outnumbering decliners by more than two-to-one on the NYSE and nearly three-to-one on the Nasdaq. However, some strategists expressed caution. Jack Ablin, chief investment officer at Cresset Capital Management, noted there was "not one ounce of skepticism among investors," questioning whether a handful of strong earnings reports can sustain record valuations.
After the close, attention turned to SpaceX (NASDAQ:SPCX) and Advanced Micro Devices (NASDAQ:AMD). SpaceX was set to hold its first earnings webcast since listing at 16:30 EDT, with analysts expecting roughly $6.8 billion in revenue and about $2 billion in EBITDA. AMD's conference call, scheduled for 17:00 EDT, was expected to focus on AI accelerator products and server market demand, with the Street looking for $11.34 billion in revenue and adjusted EPS of $1.61.
Looking Ahead
The next major catalyst is Friday's U.S. payrolls report. Strong jobs data could reinforce profit forecasts but may also reduce the odds of near-term rate cuts. Meanwhile, risks remain: the rally partly reflects optimism over diplomacy ahead of a potential Iran deal, and any breakdown in negotiations could quickly reverse the oil-driven gains. Disappointing after-market guidance from key AI names could also challenge the market's recent momentum.
