Dow Rises, But Nasdaq Drops on Global Chip Selloff
On July 28, 2026, U.S. stock markets showed divergent performance as the Dow Jones Industrial Average rose 510 points (1%) while the Nasdaq Composite fell 0.3%, driven by a global selloff in chipmaker stocks. The S&P 500 managed a modest 0.2% gain. A heavy selloff in Asian chipmakers, including a roughly 10% drop in South Korea's KOPSI index, dragged broader equity markets lower amid concerns over valuations and capital expenditure. Analysts at Sevens Report Research noted that focus would be on whether the pre-market selloff in tech stocks accelerates or stabilizes as Wall Street trading begins.
U.S. Stocks Mixed on Oil Relief and AI Doubts
U.S. stock markets ended mixed on July 28, 2026, as a temporary pause in retaliatory strikes involving Iran provided relief to energy markets, but concerns over the sustainability of the artificial-intelligence boom and high valuations of chip stocks weighed on tech shares. The Dow Jones Industrial Average rose 262.83 points (0.51%) to 52,210.08, while the S&P 500 edged up 1.20 points (0.02%) to 7,413.18. In contrast, the tech-heavy Nasdaq composite slipped 43.74 points (0.18%) to 24,932.08. The mixed performance reflects investor caution amid geopolitical tensions and skepticism about AI-driven growth, particularly in semiconductor stocks.
US: Nasdaq lags on angst over AI spending ahead of earnings reports
On Friday, July 24, 2026, the tech-heavy Nasdaq composite index declined as investors sold chip stocks amid growing concerns over massive capital expenditures on artificial intelligence. The selloff occurred ahead of upcoming earnings reports from major technology companies. The S&P 500 index barely advanced, with its biggest drag coming from the S&P 500 technology index. The market sentiment reflects anxiety that heavy AI spending may not yield immediate returns, leading to a rotation out of semiconductor and tech stocks. The article, published by The Business Times Singapore, highlights the market's focus on AI-related spending and its impact on tech sector performance.

Oil at $100 Puts Wall Street Back in ‘Risk Off’ Mode
On July 23, 2026, oil prices touching $100 per barrel triggered a broad market sell-off on Wall Street, pushing investors into 'risk off' mode. The Dow Jones Industrial Average fell 560 points (1.1%), the S&P 500 dropped 1.4%, and the Nasdaq declined 2.4%. Despite a strong labor market and Alphabet's earnings beating expectations, the firm's forecast for higher AI spending weighed on the stock in overnight trading.

Stocks Tumble After Oil Touches $100; Mag 7 Earnings Fail to Lift Markets
On July 23, 2026, U.S. stock markets opened sharply lower as oil prices briefly touched $100 per barrel, compounding investor anxiety. The Dow Jones Industrial Average fell 654 points (1.2%), the S&P 500 dropped 1.3%, and the Nasdaq declined 1.8%. The sell-off was exacerbated by disappointing earnings reports from major tech stocks Alphabet and Tesla, which failed to revive the AI-driven rally. Alphabet's increased AI spending forecasts spooked investors, while chip stocks continued their sharp monthly decline despite the broader tech weakness. The combination of rising energy costs and lackluster earnings from key 'Magnificent Seven' members weighed heavily on market sentiment.
Stock Market Today, July 17: Stocks Slide as Semiconductor Rout Deepens
On July 17, 2026, U.S. stock markets fell sharply, led by a deepening semiconductor sell-off. The Nasdaq Composite dropped 1.40% to 25,520, the S&P 500 lost 1.02% to 7,457, and the Dow Jones slipped 0.77% to 52,146. The tech rout was driven by investor rotation out of AI bellwethers like Nvidia, AMD, and Intel, as well as news that Chinese AI startup Moonshot AI released a competitive advanced model. Re-escalation of U.S.-Iran violence added to risk-off sentiment. Gold rose 0.57% to $4,010.55, and the 10-Year Treasury yield edged up to 4.55%. The energy sector was the only gainer. In contrast, insurance stocks surged after Travelers Companies reported a strong earnings beat, lifting Progressive and Allstate.
