This weekend felt like the memory/AI-infra trade roaring back to life with a vengeance, KOSPI erasing the entire July crash and DRAM names ripping on SanDisk-fueled euphoria, yet the smart-money footprints tell a wary story underneath the exuberance. CoreWeave's blowout print gave the capex bulls fresh ammo, but 13F filings showing Druckenmiller, Tepper, and the Situational Awareness fund all de-risking or getting forced out of these exact names right before the rally injects a nagging sense that this is a rally to trade, not marry. Meanwhile rates stayed benign and geopolitics stayed stuck, so the real tension this weekend wasn't macro — it was believing the memory supercycle story while watching the people who know it best quietly take chips off the table.
