#韩股跌超6%触发交易暂停 South Korean Stocks Midday Update: KOSPI Plunges 5.61%, Semiconductor Sector Sells Off Across the Board

South Korea’s KOSPI index is currently at 6484.69, down sharply by ‑5.61%. The index has fluctuated violently intraday, opening at 6528.77 today and rising to 6614.39 before turning lower, hitting an intraday low of 6400.81, with an amplitude of 3.11%. China-South Korea semiconductor ETFs also plunged 5.32%, with memory chip-heavy constituents becoming the main force behind the sell-off.

Market Analysis
South Korean stocks opened higher this morning but failed to extend their gains before plunging unilaterally. The South Korean stock market is a global bellwether for memory chips, with Samsung and other memory giants accounting for a large weighting in the index. After the memory sector continued rising in the previous period and accumulated substantial profit-taking pressure, funds rushed to lock in profits today, directly dragging the broader market sharply lower. This formed an internal and external resonance with the large capital outflows from memory leaders such as GigaDevice and CXMT in the A-share market today.
Sentiment across Asia-Pacific markets has shown a chain reaction. South Korean stocks are not the only market weakening today; the Shenzhen Component Index and ChiNext Index in the A-share market also plunged sharply, while growth and technology sectors came under broad pressure. Overseas funds have begun taking partial profits from this round of AI memory rally, no longer simply chasing prices higher, and risk appetite has clearly declined.

There is a clear divergence among sectors. Technology manufacturing has retreated sharply, while funds have likewise shifted toward defensive assets. Semiconductors and hardware stocks have sold off, while defensive assets have held up relatively well. This fund-flow behavior is highly consistent with today’s A-share market logic, with global funds simultaneously rotating from high positions to low positions. The volatility in South Korean stocks offers strong reference value. Their late-session performance will directly affect the opening sentiment of the A-share semiconductor and memory sectors this afternoon. If South Korean stocks continue to fall, high-position technology stocks in the A-share market will face further sentiment pressure; only if South Korean stocks can stop falling and stabilize will domestic technology sectors have an opportunity for sentiment recovery.

This sharp decline in South Korean stocks is not an independent move in a single market, but rather reflects the concentrated realization of profits globally after the technology sector’s major rally in this round. For A-share investors, it is important to recognize changes in the external environment. Do not rush to bottom-fish in high-position memory and computing-power sectors; wait for synchronized stabilization signals in domestic and overseas markets before considering positioning.

Asia-Pacific markets are retreating across the board. Do you think the semiconductor sector’s short-term correction is over?#我的七夕交易分享 $SK Hynix ‌
