Korea Stock Market (KRX) Today (August 6): South Korea’s stock market came under intense selling pressure on August 6 as a broad decline in global technology stocks triggered a sharp sell-off across the country’s benchmark indices. Weak sentiment from Wall Street, coupled with heavy losses in major semiconductor companies such as Samsung Electronics and SK hynix, weighed heavily on investor confidence.
The benchmark KOSPI erased much of its previous session’s gains, while the KOSDAQ showed relatively better resilience despite remaining under pressure. Investors are now closely tracking developments in the global chip industry and broader market sentiment to gauge whether the latest decline is a short-term correction or the start of a deeper pullback.
Korea Stock Market (KRX) Today (August 6): Why is the Korean Stock Market Down Today?
South Korea’s stock market witnessed another volatile trading session on August 6 as investors rushed to sell technology and semiconductor stocks following overnight weakness on Wall Street.
Heavy selling in market heavyweights Samsung Electronics and SK hynix dragged the benchmark KOSPI sharply lower. At the same time, concerns over global AI-related valuations and profit-taking across chipmakers added to the pressure.
Although the KOSDAQ proved relatively resilient, driven by gains in select biotech and robotics stocks, the broader market remained under significant selling pressure throughout the session. Investors are now closely watching whether the current correction presents a buying opportunity or signals further downside for Korea’s technology sector.
Korea Stock Market (KRX) Today (August 6): KOSPI Falls 4.16%
The benchmark KOSPI Composite Index traded sharply lower during Thursday’s session, falling 4.16% (274.29 points) to 6,323.97 by midday.
The index opened at 6,478.75, briefly climbed to an intraday high of 6,550.94, before reversing sharply and touching a low of 6,238.32. The decline erased a large portion of the previous session’s gains as investors aggressively sold technology and semiconductor shares after weakness in US markets.
Analysts attributed the decline to renewed concerns over semiconductor valuations, profit-booking after recent gains, and cautious investor sentiment following a weak performance in global technology stocks.
Korea Stock Market (KRX) Today (August 6): KOSDAQ Falls By 0.27%
Unlike the KOSPI, the technology-heavy KOSDAQ Composite Index remained relatively stable despite broader market weakness.
The index opened at 797.44, down 2.15 points (0.27%) from the previous close of 799.59. Throughout the session, it fluctuated within a narrow range just below the 800-point mark as gains in several biotech, healthcare and robotics companies helped offset weakness in semiconductor-related counters.
The comparatively smaller decline highlighted stronger buying interest in mid-cap growth stocks even as investors reduced exposure to large-cap technology names.
Korea Stock Market (KRX) Today (August 6): Samsung Electronics Falls 5.69%
Shares of Samsung Electronics came under heavy selling pressure, falling 5.69% to 232,000 KRW during midday trading.
The stock opened at 241,500 KRW before slipping to an intraday low of 229,500 KRW. Trading volume crossed 14.49 million shares, reflecting strong selling activity.
The decline followed weakness across global semiconductor stocks after a disappointing technology session on Wall Street. Investors also booked profits after Samsung’s recent rally amid growing concerns about near-term AI hardware valuations despite the company’s strong long-term outlook.
Korea Stock Market (KRX) Today (August 6): SK Hynix Down By 8.69%
SK hynix emerged as one of the day’s biggest losers, plunging 8.69% to 1,523,000 KRW.
The memory-chip giant lost 145,000 KRW from its previous close of 1,668,000 KRW as investors aggressively reduced exposure to AI-related semiconductor stocks.
The company briefly touched its daily lower limit on Nextrade’s pre-market session before recovering during regular trading. Despite the sharp decline, analysts continue to view SK hynix as one of the strongest long-term beneficiaries of AI-driven memory demand, although short-term volatility remains elevated.

- Select renewable energy firms
- Mid-cap industrial companies
These sectors outperformed as investors rotated away from high-valued semiconductor stocks.

The weakness mirrored overnight losses in US technology shares and broader profit-taking across the global semiconductor sector.
Korea Stock Market (KRX) Today (August 6): What Should Investors Know?
Although Thursday’s sharp decline reflects heightened market volatility, analysts believe investors should focus on long-term fundamentals rather than short-term price swings. Demand for AI memory chips remains strong, and both Samsung Electronics and SK hynix continue to benefit from long-term investment in artificial intelligence infrastructure.
However, profit-taking after recent rallies, uncertainty surrounding global technology valuations, and cautious sentiment following Wall Street’s weakness could keep Korean equities volatile in the near term.
Investors are also expected to closely monitor upcoming US economic data, corporate earnings, and developments in the global semiconductor industry, as these factors are likely to determine the next direction for the KOSPI and KOSDAQ.
