The Nasdaq Composite surged 1.27% on Thursday, closing at 26,198.76, as a rally in semiconductor stocks offset investor concerns regarding escalating geopolitical tensions in the Middle East. While major indices finished higher, market volatility remains elevated as traders weigh the sustainability of the artificial intelligence-driven bull market against potential macroeconomic headwinds.
Semiconductor Sector Drives Market Gains
The PHLX semiconductor index recorded its second consecutive day of gains, led by significant momentum in AI-related hardware. Micron Technology shares jumped following the company’s announcement of a long-term strategic plan to invest more than $250 billion in the United States by 2035. This capital expenditure is aimed at scaling domestic memory chip production to meet the rising demand for artificial intelligence infrastructure.
Additional momentum in the sector came from gains in Applied Materials and SanDisk. Furthermore, Meta Platforms saw its share price rise following reports that the company is preparing to begin internal manufacturing of its own AI-specialized chips starting in September.
Geopolitical Risks and Market Sentiment
Despite the positive performance in technology stocks, broader market sentiment remains tempered by instability in the Middle East. Markets reacted to reports of intensified conflict, with Tehran claiming military strikes against U.S. interests in Kuwait, Qatar, and Bahrain following U.S. military actions in the region on Wednesday.
Ross Mayfield, an investment strategy analyst at Baird, noted that while the current environment remains an AI-driven bull market, the rally’s breadth is fragile. According to Mayfield, the market’s ability to sustain this momentum is contingent on oil prices and interest rates remaining anchored; the current geopolitical flare-up introduces uncertainty that challenges those assumptions.
Economic Data and Federal Reserve Policy
The broader market showed resilience despite mixed economic signals. The S&P 500 gained 0.79% to close at 7,541.83, while the Dow Jones Industrial Average rose 0.25% to 52,481.70. Labor market data released Thursday provided a stable outlook, as initial jobless claims for the previous week declined, suggesting that the labor market remains steady despite the cooling in job growth observed in June.
Federal Reserve policy remains a primary focus for institutional investors. Although the Federal Reserve maintained interest rates at its June meeting under Chair Kevin Warsh, minutes from that session revealed that some policymakers advocated for an increase in borrowing costs before ultimately deciding to hold rates steady. Current market sentiment, tracked by the CME FedWatch tool, indicates that traders are pricing in a high probability of a 25-basis-point rate hike by the December meeting.
Earnings Outlook and Retail Performance
As the second-quarter earnings season approaches, expectations remain high for the technology sector. Analysts surveyed by LSEG I/B/E/S project a 24% year-over-year increase in S&P 500 earnings, with technology firms expected to drive the majority of that growth. The S&P 500 is currently trading at approximately 20 times expected earnings, a contraction from the 21-times multiple observed one month ago.
Individual company performance provided a contrast to the broader index gains:
- PepsiCo: Shares declined despite the company surpassing revenue estimates for the second quarter.
- Costco Wholesale: The retailer’s stock fell to a six-month low after reporting a deceleration in comparable sales figures for the month of June.
