US Memory Chip Stocks Slide Premarket, SanDisk, Micron, Western Digital, SK Hynix Down Over 2%

On August 28, 2026, US-listed memory chip stocks fell in premarket trading, with major players including SanDisk, Micron Technology, Western Digital, and SK Hynix each declining more than 2%. The broad-based downturn reflects investor caution in the semiconductor storage sector, though no specific catalyst was cited in the report. The declines were observed across both US and Korean memory makers, indicating a sector-wide trend rather than company-specific issues. As of the premarket session, all four companies were trading lower, with losses exceeding the 2% threshold. The move comes amid ongoing market volatility in tech stocks, and traders will be watching for further developments during regular trading hours.
