Why Is Micron (MU) Stock Price Up 5.50% Today, Sep 17? AI Memory Squeeze Fuels Big Tech Hardware Rebound

Micron's 5.5% jump reflects renewed confidence that tightening DRAM/HBM supply, reinforced by Intel's warning on worsening memory shortages, can support near-term pricing power.

Attention remains on whether tight memory conditions persist into Micron's upcoming earnings, keeping semis sensitive to supply-chain and macro-rate shifts.
