Key Players and Relevance

On this Thursday morning, the three major indices of Wall Street are advancing. The most closely watched stock averages are up, with chip manufacturer Micron providing relief to the market following fears of an AI bubble.

Major Indices Performance

  • Dow Jones Industrial Average: Up 0.55% to 48,148.76
  • S&P 500: Up 0.79% to 6,774.81
  • Nasdaq Composite: Up 1.66% to 23,069.41

Micron Technology’s Impressive Gain

Shares of Micron Technology soared 11.90% after forecasting nearly a 200% increase in its fiscal second-quarter profits. This surge is attributed to rising chip prices due to supply shortages and the growing demand for AI data centers.

Market Confidence Regained

Micron’s projections have instilled a sense of certainty in the market. Recently, Wall Street displayed skepticism due to increased corporate capital expenditure on AI-related projects, which have squeezed profit margins for several companies.

“Wall Street advances following the widespread sell-off on Wednesday, led by the technology sector, supported by Micron’s robust forecast that offers some relief from the AI bubble narrative,” according to analysts at GBM.

Other Economic Indicators

The Consumer Price Index in the United States increased less than expected through October. The Labor Statistics Bureau, part of the Department of Labor, did not release the monthly IPC changes due to the prolonged government shutdown.

Nine out of eleven S&P 500 sectors are in the green. Notable gainers include discretionary consumer spending (+2.43%) and communication services (+1.91%). The former is bolstered by Amazon.com (+3.24%) and Tesla (+3.83%), while the latter is supported by Meta (+2.76%) and Alphabet (+1.89%).
