Korean stocks crash in a rout! The Korea Composite Index (Korean: KOSPI) plunges more than 11%, with Samsung and SK hynix both tumbling more than 13%

The Korean market saw extreme conditions today. The decline in the Korea Composite Index widened to 11.29%, directly breaking below the 6,000-point mark; compared with the historical high in June, the cumulative pullback is nearly 35%.
Storage giants were hit hard across the board: SK hynix fell 14.15%, while Samsung Electronics plunged more than 13%, and panic sentiment in the global semiconductor sector spread further.
The core reason behind this selloff is still the sharp surge in U.S. bond yields at elevated levels, which suppresses high-valuation growth assets. Coupled with the storage sector’s massive gains within the year, investors rushed to take profits, prompting panic-driven selling of assets.
The global AI storage industry chain is under collective pressure. Near-term sentiment for U.S.-listed peers such as Micron will also be dragged down, and short-term sector volatility will likely be amplified further.
However, the industry fundamentals have not changed: DRAM price increases and the tight supply-demand situation for HBM remain. The sharp drop is more a valuation “estimate kill” driven by macro sentiment rather than a breakdown of industry logic.
