Three AI Memory Stocks to Watch Through July 2026: Samsung, SK Hynix, SanDisk

Samsung Electronics, SK Hynix and SanDisk are showing strong AI memory fundamentals but signs of cautious investor positioning heading into late-July catalysts. According to BeInCrypto, Samsung guided for Q2 operating profit of ₩89.4 trillion versus ₩87.3 trillion expected and revenue of ₩171 trillion, yet shares fell nearly 7% as foreign investors sold about 26 million shares over six sessions; full results are due July 30. SK Hynix, a key HBM supplier to Nvidia, fell 6.06% with roughly 3.3 million shares sold by foreigners ahead of July 29 earnings. SanDisk is up over 500% YTD but down about 16% in five days, with put-call ratios above 1 and weakening money-flow signals.
