Goldman Sachs turned positive on the memory chip sector in its latest research report, stating that "the worst days are behind us," triggering a broad rally in memory stocks on Wednesday. SK Hynix's US-listed shares led the gains, hitting an all-time high intraday before closing up approximately 7% at $193.53. Micron Technology closed up about 2% at $1027.77, and SanDisk closed up about 1.51% at $1764.17. Goldman Sachs noted that Micron and SanDisk have broken through their summer downtrends, and hedge fund positioning remains low, leaving room for capital inflows. However, Kioxia CEO Hiroo Ota warned on the same day that NAND prices have risen sufficiently, and excessive chasing of prices could harm industry growth.
