Wall Street Opens Mixed as Technology Stocks Extend Losses
US stocks opened mixed on Thursday, October 15, 2026, as selling pressure intensified across artificial intelligence and semiconductor companies. The Nasdaq Composite suffered the sharpest decline among major benchmarks, while the Dow Jones Industrial Average advanced despite concerns about inflation and borrowing costs.
At 9:30 a.m. Eastern Time, the Dow rose 266.74 points, or 0.52%, to 51,888.22. The S&P 500 declined 33.35 points, or 0.43%, to 7,685.59, while the Nasdaq Composite dropped 329.86 points, or 1.24%, to 26,363.01. These were opening-session readings, not closing prices.
The divergence reflected growing concerns about financing requirements and valuations of artificial intelligence businesses. Investors were also reacting to economic figures indicating persistent inflation pressures.

Nasdaq Today: AI and Semiconductor Stocks Face Heavy Selling
Technology shares remained under pressure following Wednesday’s steep losses. Nvidia, Advanced Micro Devices and companies associated with AI infrastructure were among those affected. In early Thursday trading, Nvidia declined approximately 3.2%, while AMD lost around 5.4%. AI computing infrastructure company CoreWeave also faced selling pressure.
The decline reflected concerns about the sustainability of substantial AI investment commitments as borrowing costs remain elevated. Businesses financing data centres, computing equipment and infrastructure through debt face closer scrutiny when interest rates rise. Investors were evaluating whether commercial returns would justify the scale of capital spending across the industry.
The selling extended beyond Wall Street. South Korea’s Kospi declined approximately 7.6% in a reported session snapshot, reflecting broader weakness in technology-related equities.
S&P 500 Today: Inflation and Interest Rates Pressure Valuations
The S&P 500 opened lower as investors assessed the implications of persistent inflation for corporate profitability and monetary policy. Wednesday’s US consumer inflation report had already heightened concerns about possible additional Federal Reserve rate increases. Thursday brought further evidence of price pressure through wholesale inflation data.

Wholesale prices rose more than economists had anticipated, with higher energy costs contributing to the increase. Persistent inflation creates challenges for businesses through operating expenses and financing costs. It can also affect stock valuations because higher bond yields reduce the present value of expected future earnings, particularly for rapidly growing companies.
Dow Jones Today: Industrial Average Outperforms Nasdaq
The Dow Jones Industrial Average performed better than the technology-heavy Nasdaq during Thursday’s opening session. Its advance of more than 260 points highlighted the uneven nature of the selloff. While AI-linked companies suffered significant declines, other established businesses attracted comparatively stronger interest.
The benchmarks have different compositions. The Nasdaq is more heavily exposed to growth-oriented technology companies, while the Dow includes industrial, financial, healthcare and consumer businesses. Their contrasting performances suggested investors were reassessing specific industries rather than selling US equities uniformly.
US Retail Sales Rise as Gasoline Spending Lifts Headline Growth
New economic data added to the debate about consumer demand and inflation. US retail sales increased 0.8% in September, following a revised 1.3% rise in August. The latest reading exceeded economists’ expectations of approximately 0.3%.

Gasoline purchases accounted for an important share of the increase. Sales at gasoline stations climbed 6.4%, while retail sales excluding gasoline rose only 0.2%. The figures suggested that higher energy costs were influencing total spending rather than the headline increase necessarily reflecting stronger underlying demand across retail categories.
Federal Reserve Outlook Remains Central to Trading
The Federal Reserve’s interest-rate outlook remained a central concern. The October Beige Book, released Wednesday, described modest employment growth and strong price increases. It also indicated that consumer spending was broadly unchanged across many districts, with lower-income households showing greater caution.
The combination of persistent inflation and uneven economic growth complicates monetary policy expectations. For companies dependent on financing future expansion, sustained high borrowing costs can be especially important.
What Wall Street Is Watching Next
Investors were monitoring whether technology stocks could stabilise after consecutive sessions of selling and whether the Dow could maintain its relative strength. Further corporate earnings, Treasury yield movements and energy prices remained key influences.

Thursday’s opening session demonstrated the widening divide between AI-related businesses and other parts of the US equity market. The next phase of trading would indicate whether the technology selloff remained concentrated in AI-linked companies or spread more broadly.
