The same share of the same company traded at two prices this week, roughly a third apart, and there was nothing anyone could do about it. SK Hynix’s American depositary receipts have run as much as 51% above the Seoul-listed common stock since the July 10 Nasdaq debut, settling around a 33% premium midweek. That gap is not a signal about DRAM pricing, HBM allocation, or Nvidia’s qualification schedule. It is a plumbing failure, and the plumbing is the point.
