South Korea's benchmark stock index, the KOSPI, experienced extreme volatility in Monday's trading after posting a decline of more than 5%. This sharp drop forced exchange authorities to temporarily halt trading to curb market panic triggered by a massive sell-off in tech giants.
The negative sentiment arose alongside growing concerns among global market participants regarding artificial intelligence (AI) valuations and semiconductor sector earnings. Top-tier South Korean tech companies were the hardest hit; SK Hynix Inc reportedly plummeted nearly 10%, while Samsung Electronics slid more than 6% after its latest financial report disappointed investors.
This situation also spilled over into the semiconductor supply chain in other parts of Asia. Companies like Kioxia Holdings Corp, Murata Manufacturing, and TDK Corp recorded significant price corrections. This phenomenon reflects investor skepticism about whether the massive capital expenditures allocated by tech companies for AI infrastructure can deliver commensurate returns in the future.
The selling pressure marks a period of high volatility currently sweeping Asian capital markets. After recording a rally of gains over the past few months, market participants are now adopting a more defensive stance, questioning the sustainability of memory chip profitability in covering the high investment costs of AI research and development.
