Memory stocks, including Micron, SK Hynix, SanDisk, Western Digital, and Seagate, all rallied double-digits today, with SanDisk surging 22% and Micron climbing 15%. This broad market strength, also reflected in a 13% rise for the Roundhill Memory ETF, follows a warning from South Korean tech giant Samsung about tightening memory supplies. The development, coupled with improving sentiment toward semiconductor demand and a broader rebound in technology stocks, is seen as potentially boosting pricing power for memory manufacturers.
