CXMT DRAM Breakthrough Hammers Memory and Optical Stocks — Panic or Repricing?
AI hardware sold off hard Monday: SanDisk -5.97%, Lumentum -9.78%, Micron -3.88%, SK Hynix -4.02%. Trigger: CXMT's president announced a 4F² DRAM architecture breakthrough at a weekend conference, targeting server memory by end-2026 — reviving fears of Chinese competition on pricing.

Bulls say CXMT still faces major yield hurdles before any volume ramp; bears say once markets price in Chinese DRAM competition, fundamentals can't stop the re-rating. Has this changed your conviction in memory stocks?
