Tech and Semiconductor Stocks Slump Led by Qualcomm and Corning Amid Valuation and AI Rivalry Concerns

In a move reflecting intensifying competitive pressures within the AI sector, technology and semiconductor stocks experienced a sharp collective sell-off. According to reports, Qualcomm led the decline with a 9.52% drop driven by Nvidia's emergence as a formidable rival in the AI PC chip market, while Corning Inc fell 10.11% as investors re-evaluated elevated valuations. The downturn extended to Tesla, which declined 4.11% impacted by Bitcoin depreciation losses and broader negative macroeconomic data.

This correction arrives as the sector faces dual pressure from rising yields and fierce technological rivalry, following Nvidia's recent launch of its Blackwell processors which raised the bar for performance and pricing. Compared to the previous quarter, analysts suggest that valuations for firms like Corning and Texas Instruments now require exceptional growth to justify current levels, especially after strong U.S. jobs data reduced hopes for imminent Fed rate cuts. Per market data, this retreat represents one of the most significant weekly shakeouts for the semiconductor industry this year.

Looking at closing levels on June 5, 2026, traders are monitoring whether QCOM can stabilize above key technical support levels following this downward gap. Moving forward, markets are awaiting Fed Chair Powell's speech scheduled for May 31 (per the economic calendar) for clues on monetary policy, alongside the ISM Manufacturing PMI release on June 1, which will be pivotal in determining risk appetite for growth and tech equities.
