Chip stocks crash in Seoul while DRAM contract prices climb 20 to 30 percent
On July 28, 2026, the semiconductor selloff turned brutal in Seoul: SK Hynix closed 14.65% lower and Samsung Electronics fell 13.4%, dragging the KOSPI to its biggest one-day drop since March, in the fourth straight losing session for chip stocks globally. Investors were spooked by reports of China's progress on domestic chipmaking equipment including DUV lithography, circular financing unease, and stretched valuations. Meanwhile third-quarter DRAM contracts are settling 20 to 30% higher this month, as AI memory demand keeps prices climbing.
