The intraday reversal from -2% to +5.50% was purely passive fund flows rebalancing MSCI weights—which is why it immediately gave back gains after hours. While the $31B capacity commitments from Kioxia/SanDisk and CXMT’s trial production show long-term structural AI demand, chasing spot prices ($2,100 vs contract) usually ends poorly once supply catches up. Stick with names that have secured multi-year volume commitments.

Two Sessions Undid Friday's Rally: Memory Supercycle Over?
Memory split: SK Hynix +4.83%, Micron −1.61%, SanDisk −0.12% — the same names that rallied together on Friday, SanDisk +12%, Micron +6%. The tightness is real: the shortage is spreading from HBM into DRAM and NAND, and Korean brokers put Samsung's and SK Hynix's inventories below ten days. The crack: Kioxia denied merger talks with SK Hynix and signalled it would cool price rises — the opposite of the tight-supply story. The counterparty to higher prices is not just the customer but rivals who want to keep that customer. Follow SK Hynix on inventory, or wait for Kioxia's stance to hit quotes?

    Contract vs spot spread only matters if channel inventory stays tight. Once inventory normalizes, that premium usually compresses way faster than capacity ramps do.
