U.S. equities surged to record highs on Tuesday, with the Dow Jones Industrial Average crossing the 54,000 threshold for the first time. The blue-chip index climbed 1.6%, while the S&P 500 advanced 1.4% and the Nasdaq Composite jumped 2.0%, reflecting a broad risk-on sentiment fueled by robust artificial intelligence-related earnings.
The market's advance was led by semiconductor and industrial stocks, as AI investment increasingly extends beyond software into hardware and infrastructure. The PHLX Semiconductor Index soared 5.7%, marking its fourth consecutive session of gains, its best streak since November 2022. This broadening of AI demand is evident in rising orders for optical connections, power semiconductors, and industrial machinery, indicating that the AI boom is now lifting a wider range of suppliers.
Economic Data Presents Mixed Picture
Official data released Tuesday painted a divergent economic landscape. Total factory orders declined 0.3% in June, missing the Reuters poll expectation of a 0.2% increase. However, orders for computers and electronics surged 3.2% month-over-month and jumped 13.9% year-over-year, underscoring the strength in tech-related manufacturing. Core capital-goods orders rose 1.2%, with shipments up 2.0%, suggesting resilient business investment.
Labor market indicators pointed to a gradual cooling. Job openings fell by 178,000 to 7.359 million, while hiring increased by 96,000 to 5.348 million. Layoffs remained relatively stable at 1.77 million, consistent with a market characterized by slow hiring and firing.
Company Highlights: Palantir, Caterpillar, Onsemi
Palantir Technologies (NASDAQ:PLTR) surged 25.9% to $158.25 after raising its 2026 revenue guidance to $8.150-$8.158 billion, up from $7.650-$7.662 billion. The company's second-quarter revenue jumped 93% year-over-year to $1.94 billion, with CEO Alex Karp noting the company is compounding at an unprecedented rate and scale.
Caterpillar (NYSE:CAT) gained 6.4% to $882.74 after lifting its full-year sales growth outlook. Quarterly revenue climbed 24% to $20.54 billion, with construction sales up 35% and the power and energy segment up 17%. Analyst Kristen Owen of Oppenheimer called the construction-driven performance “a standout.”
Onsemi (NASDAQ:ON) rose modestly after forecasting a more than twofold increase in its AI data-center revenue for 2026. The company's third-quarter revenue midpoint of $1.70 billion exceeded analyst expectations of $1.67 billion.
Market Breadth and Sector Performance
While overall sentiment was upbeat, market breadth was uneven. Advancing stocks outnumbered decliners by more than two-to-one, but seven of the 11 S&P 500 sectors traded lower earlier in the session. The energy sector fell 2.5% as oil prices dropped. WTI crude declined 5.45% to $75.96, alleviating inflation concerns, while gold gained 1.08% to $4,134.80.
Earnings season continues to show strength, with 85.2% of S&P 500 companies beating estimates, well above the historical average of 67.5%.
Looking Ahead: SpaceX Earnings and Risks
Investors are eyeing SpaceX (NASDAQ:SPCX) inaugural earnings after the market close. Options pricing implies a 15% swing, with analysts projecting an operating loss of $1.55 billion on revenue near $7 billion. A disappointing report could test investor appetite for AI risk.
Goldman Sachs forecasts Brent crude to trade in the $80-$90 range until a U.S.-Iran agreement is reached or hostilities escalate, posing a potential inflation risk. Despite these uncertainties, the market's upward momentum remains strong, driven by the expanding AI investment cycle.
