KOSPI and KOSDAQ 5% or more, memory concentration amplified the shock

As geopolitical risks stemming from the Strait of Hormuz resurfaced, 7month 8day, domestic stocks plunged. Both KOSPI and KOSDAQ fell by 5% or more, sharply weakening investor sentiment.

In particular, concentration in memory semiconductor stocks, which had driven the market, amplified this decline. The plunge in large-cap memory stocks contributed to the widening decline in the indices.

Detailed figures by quantitative indicator and trends by trading participant are still being compiled. Related breaking news and summary materials are expected after the market closes.

By contrast, the Hong Kong and Taiwan stock markets rose on the same day. The divergent market trends are noteworthy.

The stock market plunge is expected to make changes in the positions of individual investors and institutions more visible. In the market, portfolios with high memory dependence suffered greater damage.

The major sector-by-sector declines identified in trading that day were concentrated in memory-related areas. Other sectors posted relatively smaller declines.

The relevant figures will be updated as additional disclosures or company-specific announcements are released. It will be necessary to monitor subsequent trading trends and respond accordingly.
