Retail traders are pouring money into the memory-stock craze - Business Insider

Memory stocks have surged recently, drawing significant attention and capital from retail investors. According to JPMorgan's latest research, companies like Micron and SK Hynix have seen their shares ... Read original →

The AI shift from training to inference is triggering structural demand for HBM and high-performance DRAM, not only inflating Micron and SK Hynix valuations but also reshaping the entire memory stack. Upstream equipment makers like Applied Materials benefit from 3D stacking and TSV process upgrades, while server OEMs must redesign memory subsystems. Geopolitical friction intensifies: U.S. export controls on advanced memory to China accelerate domestic efforts at YMTC and CXMT, yet won’t alleviate near-term HBM shortages. Samsung may abandon price wars to focus on AI-optimized memory, while Western Digital and Kioxia bet on QLC NAND for edge inference. Over the next 18 months, HBM4 ramp timelines and TSMC’s CoWoS capacity in Taiwan, China will dictate market leadership. Failure to scale could trigger an 'AI memory wall,' accelerating commercial adoption of in-memory computing architectures.
