On October 13, SanDisk Corp. fell 3.72% in Pre-Market Trading, trading around $1436.78 per share, with turnover of $58.82 million.

The move coincided with renewed pressure across memory-related names after ChangXin Memory Technologies announced key progress in its 4F² DRAM architecture research, reinforcing market concerns that storage-chip competition could intensify.

Recent market reports showed the broader memory group weakening alongside SanDisk Corp., with peers including Silicon Motion, Micron Technology, SK hynix and Western Digital also trading lower. Additional context pointed to cautious positioning in the sector, including foreign ownership in SK hynix remaining in the 49% range for eight consecutive trading days, which was viewed as a sign of more guarded investor sentiment toward memory stocks.
