Micron and SanDisk are both trading roughly 25 percent below their June highs after Samsung's shareholder return plan came in below what the market wanted. The mechanism is simple. Samsung's board approved 90 to 110 trillion won versus expectations closer to 140 trillion, and the immediate buyback tranche was smaller than SK Hynix's own program from earlier this month. None of that changes underlying DRAM and NAND demand. It changes sentiment around capital discipline in a sector that just had its best year in a decade. Micron is still up close to 190 percent for 2026, so this reads more like profit taking after an extreme move than a reversal of the AI storage thesis.
