DRAM is trading 5.14% down at $52.19 as memory-chip stocks sell off amid concerns about competition from China's CXMT.

  • Reports say CXMT has made progress on a denser 4F² DRAM design and plans server-memory products by year-end, raising concerns about future competition and pricing pressure.
  • Samsung and SK hynix also fell; no DRAM-specific company announcement was identified. The ETF's listed holdings include Samsung, SK hynix and Micron.
  • U.S. indices were nearly unchanged, pointing to memory-sector rather than broad-market news.
