Why Is Micron Technology (MU) Stock Price Up 18.36% Today, July 30? AI Outlook Revives Memory Demand

Micron surged after Microsoft's stronger cloud outlook eased fears that AI infrastructure spending is overextended, improving sentiment across the semiconductor complex. The move appears primarily driven by a sector-wide risk reset rather than new Micron-specific fundamentals, reinforcing Micron's leverage to data-center capex and high-bandwidth memory demand expectations. Near-term focus is likely to remain on follow-through in chip risk appetite and upcoming cloud capex commentary.
