DRAM Breakout Ignites Memory-Stock Rally in WDC, MU, STX, and SNDK
Memory-chip names led the session as Western Digital (WDC) jumped about 16%, Micron (MU) up ~11%, Seagate (STX) ~9.4%, and SanDisk (SNDK) ~6.5%, with the Roundhill Memory ETF climbing ~9% on the DRAM upcycle. Morgan Stanley lifted WDC’s price target to $650 citing stronger HDD demand and new UltraSMR/HAMR products, while SK Hynix and Samsung also gained. The broader rally followed a US–Iran peace deal, with the memory sector showing notable year-to-date gains (SNDK ~788%, MU ~280%, WDC ~280%, STX ~271%), and StockTwits sentiment flipping to bullish for WDC.
