Micron down 6%, SK Hynix and SanDisk 5%: why is memory trade crashing?

Micron (MU) and SanDisk (SNDK) fell sharply in US premarket, reversing Monday’s strong memory-chip rally as investors trimmed exposure to 2026’s hottest AI winners. Micron was indicated about 6% lower around 5:30 a.m., signaling a near-term risk-off move in memory/AI-related semis rather than a company-specific fundamental update.
