- The strong performance guidance announced by Micron Technology (MU:US) and Qualcomm (QCOM:US) indicates that demand for artificial intelligence infrastructure remains robust, effectively alleviating market concerns about rising borrowing costs and overvaluation of tech stocks.
- Nasdaq 100 index futures surged over 2% in pre-market trading, mainly driven by an 18.7% jump in Micron's European-listed shares, as the chip sector's recovery boosted global tech stocks.
- Market focus has shifted to the upcoming U.S. Personal Consumption Expenditures (PCE) Price Index, as economists expect the annual inflation rate to reach 4.1%, heightening expectations in the interest rate futures market for a Federal Reserve (Fed) rate hike in September.
Demand for AI Infrastructure Validates Industry Growth Momentum
The latest financial forecasts released by chip manufacturers Micron Technology and Qualcomm have reassured global investors. Micron disclosed that customers have committed $22 billion to secure supplies of its high-bandwidth memory chips, while Qualcomm predicts its data center business revenue will reach $15 billion by 2029. These high-frequency data points directly confirm that capital expenditure on AI hardware by hyperscale cloud service providers and various industries has not slowed, effectively countering recent market skepticism about an AI bubble burst.
Futures Market's Rebound Eases Monthly Tech Stock Pullback Pressure
Stimulated by the favorable earnings reports, U.S. stock index futures showed mixed pre-market performance, with the tech-heavy Nasdaq 100 E-mini contract surging 606.75 points, or 2.06%; S&P 500 futures rose 0.71%, while Dow futures edged up only 0.13%. Before this rebound, the Nasdaq index was facing its largest monthly decline since March 2025, and the Philadelphia Semiconductor Index (SOX) was also under pressure. The optimistic guidance from Micron and Qualcomm effectively offset market fears of rising debt financing costs due to increased capital expenditure, injecting immediate liquidity confidence into the tech sector.
Supply Chain Capital Expenditure Expansion Triggers Global Semiconductor Sector Revaluation
Despite Micron's clear plans to expand capital expenditure in its earnings report, the market interpreted it as a signal of tight supply-demand balance in the industry, supported by strong revenue expectations. This quarter, Micron and Qualcomm's U.S.-listed shares have risen by over 200% and 50%, respectively, leading the Philadelphia Semiconductor Index towards a historically strong quarterly performance. Related semiconductor supply chain stocks in Europe and Asia also saw valuation corrections during trading, indicating that the prosperity of the AI industry chain is being transmitted from core chip design to equipment and materials.
Macroeconomic Inflation Concerns Suppress Long-term Valuation Expansion
Despite impressive micro-level corporate earnings, macroeconomic tightening pressures remain a key variable limiting further market upside. The upcoming U.S. PCE Price Index is expected to rise 4.1% year-on-year, far exceeding the Federal Reserve's official target of 2%. According to the CME's FedWatch tool, traders are pricing in the possibility of a 25 basis point Fed rate hike as early as September. If core inflation data continues to rebound, rising risk-free rates could lead to a revaluation risk for tech stocks' forward price-to-earnings ratios.
