True
Both the KOSPI and KOSDAQ indexes fell roughly 7 percent in a simultaneous market rout, marking one of the steepest same-day declines for the two boards in recent memory. The synchronized drop underscores the severity of selling pressure across large-cap technology shares and smaller growth stocks alike.
The decline was not confined to a single sector or market segment. The KOSPI, home to heavyweight names such as Samsung Electronics and SK hynix, and the KOSDAQ, which lists a wider range of mid-cap and growth companies, both lost ground in the 7 percent range, indicating that the sell-off swept across the entire market rather than targeting individual stocks.
A fact-check review of the claim, which examined 11 primary sources, including official exchange materials, found the figure to be accurate.
A simultaneous 7 percent-class decline on both indexes represents a significant shock for Korean markets, which are heavily weighted toward semiconductors and related hardware. Such broad declines typically reflect large-scale institutional selling and heightened risk aversion among investors, though the precise trigger for this session's slide was not detailed in the reviewed sources.
The severity of the fall places it among the sharpest single-day moves for the Korean market, comparable to other historical panic-selling sessions in which both boards dropped in tandem.
The claim that the KOSPI and KOSDAQ both crashed 7 percent together is True.
