US stock index futures advanced broadly on Tuesday, with Nasdaq 100 futures leading the gains. Investors are shifting their focus to a slate of major corporate earnings reports scheduled for this week, aiming to gauge the sustainability of the artificial intelligence-fueled market rally.

As of early Tuesday morning Eastern Time, futures for the Dow Jones Industrial Average were up approximately 0.2%, S&P 500 futures gained 0.4%, and Nasdaq 100 futures surged 1.3%. The semiconductor sector showed signs of recovery following last week's sell-off, with Micron Technology shares rising over 5% in pre-market trading. SanDisk and Western Digital also posted notable gains.

Market Attention on Major Tech Earnings

Market attention is concentrated on earnings reports from major technology companies due this week, including Alphabet (Google's parent company), Tesla, Intel, and IBM. The performance of these companies will serve as a crucial test of whether the AI-driven capital expenditure boom can justify current high valuations. Additionally, several other prominent firms, including Charles Schwab, 3M, General Motors, and Novartis, are set to report earnings before the market opens on Tuesday.

Context of Recent Semiconductor Weakness

Last week, the Philadelphia Semiconductor Index fell more than 20% from its late June peak, entering technical bear market territory. Analysts noted that this decline reflected a rotation of capital rather than a deterioration in fundamentals. Following visits to data center procurement channels, Morgan Stanley confirmed that the intensity of the memory chip shortage has not abated. The market is also monitoring geopolitical risks, such as the US-Iran conflict, for their potential impact on oil prices.
