Summary · why it matters

Samsung Electronics fell 13.4% and SK Hynix dropped 14.7% on Tuesday, marking Samsung's worst one-day decline in almost two decades and helping push South Korea's KOSPI index down 10.8%, its largest daily decrease since the early period of the U.S.-Iran conflict in March. The selloff came as investors assessed concerns about AI-infrastructure financing, semiconductor valuations, and increasing competition from China, with reports that Chinese companies were developing domestic deep-ultraviolet lithography equipment renewing fears that Chinese memory producers could expand capacity more rapidly. SK Hynix, a leading supplier of high-bandwidth memory chips used in AI systems, had its U.S.-listed shares close 7.5% lower at $143.02 on Monday, their first finish below the $149 listing price since the company's Nasdaq debut earlier in July. Together, Samsung and SK Hynix represent nearly half of the KOSPI, meaning their double-digit declines transmitted substantial pressure directly into the benchmark index. SK Hynix is scheduled to report earnings on Wednesday, its first results since the Nasdaq listing, and investors may now examine whether those earnings support current HBM expectations and whether China's developing equipment can achieve the reliability, performance, and commercial scale required to intensify competition.
