Why Is Micron (MU) Stock Price Up 5.00% Today, Sep 22? Tight DRAM Supply and AI Memory Demand Lift MU

Micron's 5% jump reflects renewed confidence that tight DRAM supply and sustained AI-server memory demand can extend the current pricing/margin upcycle into the Sep 30 earnings catalyst. Analyst reiterations and a broader rally in memory/storage peers suggest sector-wide risk appetite is improving. Near-term focus is on whether the move holds above recent support and confirms continuation, as positioning into earnings can amplify volatility.
