Why Is Micron Stock Still Falling?

Micron Technology shares dropped 3.2% despite Taiwan Semiconductor Manufacturing Company reporting strong Q2 earnings and raising capital spending guidance—developments that should bolster demand for Micron's memory products. TSMC's expanded AI chip production directly drives consumption of Micron's high-bandwidth memory (HBM) chips, making the sell-off a potential disconnect between headlines and fundamentals.

Separately, Micron signed strategic supply agreements with seven major automotive suppliers, securing revenue visibility and margin protection in a sector critical to the company's diversification strategy. The automotive deals provide contracted demand at a time when memory chip pricing remains volatile.

The contrast is sharp: TSMC's increased capex signals robust AI infrastructure buildout, which requires the exact HBM products Micron manufactures. Yet the stock traded lower, suggesting traders may be focused on broader memory market concerns or near-term cyclical headwinds rather than the positive demand signal embedded in TSMC's guidance.
