Asian semiconductor stocks suffered a sharp selloff today. SK hynix dropped roughly 10%, Samsung Electronics fell 7.4%, South Korea’s KOSPI declined more than 5%, and Japan’s Kioxia also saw double-digit losses. What makes this interesting is that AI memory demand has not suddenly disappeared. Instead, investors are reacting to a potential shift in the global memory supply landscape, driven partly by a technological breakthrough from China. On October 12, Chinese memory manufacturer CXMT (ChangXin Memory Technologies) disclosed progress in its next-generation 4F² DRAM cell architecture, with plans to introduce server memory products using the technology by the end of this year. Compared with the industry’s mainstream 6F² structure, the new architecture could potentially increase memory den
ASML reports today—which metrics matter most in semis Q3 season?
Semiconductor Q3 earnings season starts today: ASML reports October 14 a.m. ET, TSMC October 15 a.m. Watch ASML's EUV order book — the read on fabs' 12-to-18-month capex confidence — plus TSMC's CoWoS capacity constraints, full-year AI chip demand and margin guidance. Bulls say neither has signaled cooling demand; sustained guidance extends AI capex momentum. Bears say memory stocks just reeled from China's domestic DRAM breakthrough, and weak equipment orders would pressure the whole semiconductor chain. If ASML's order book disappoints, how far beyond semis does the damage spread?
