The KOSPI index has fallen, with reports varying on the extent of the decline, below 7,000 or even 6,800. Samsung and SK hynix stocks have plummeted, with SK hynix experiencing a significant drop after its Nasdaq debut, possibly due to profit-taking or diminishing earnings optimism. The decline in the stocks and the KOSPI index may be attributed to various factors, including a chip rout, geopolitical concerns, and fed jitters.
