Korea Stock Market (KRX) Today (August 10): After one of the most turbulent stretches for South Korean equities in recent weeks, investors returned to the market on Monday, August 10, looking for signs that the sharp semiconductor-led correction may finally be losing steam. Seoul shares opened higher after Wall Street posted record gains, while renewed buying in technology and chip stocks gave the battered market an early lift. The rebound came as investors reassessed the outlook for artificial intelligence spending, U.S. interest rates and the earnings prospects of Korea’s biggest semiconductor companies.
The KOSPI opened 0.76% higher at 6,306.33, while the KOSDAQ advanced more sharply as investors moved into technology, biotechnology and other growth-oriented shares. However, the recovery remained fragile as foreign investors returned to selling later in the morning, preventing the main index from holding all of its early gains.
The latest session therefore offered a mixed message: buyers are willing to return after the recent sell-off, but investors remain cautious about whether the rebound can turn into a sustained recovery.
Korea Stock Market (KRX) Today (August 10): Why is the Korean Stock Market Up Today?
The immediate trigger for Monday’s recovery came from Wall Street, where U.S. stocks ended the previous week at record levels. The stronger global risk appetite encouraged investors in Seoul to hunt for stocks that had fallen sharply during the recent correction.
Technology shares became the main beneficiaries. Samsung Electronics and SK Hynix, two of the most influential companies on the Korean market, recovered after suffering heavy losses during the previous week. Their rebound provided an important lift to the KOSPI because of the companies’ large influence on the benchmark.
Investors also reacted to renewed optimism surrounding the semiconductor cycle. Recent reports suggested that the market’s sharp correction in memory-chip stocks may have gone too far, encouraging some investors to rebuild positions.
The interest-rate outlook also supported sentiment. Expectations for easier U.S. monetary policy have increased following weaker-than-expected U.S. employment data, improving the appeal of risk assets across Asia.
However, the recovery is not without risks. Foreign investors continued to sell Korean shares during Monday’s session, causing the KOSPI to give up part of its early advance. Yonhap reported that Seoul shares pared their gains as foreign selling increased later in the morning.
Korea Stock Market (KRX) Today (August 10): KOSPI
The benchmark Korea Composite Stock Price Index opened at 6,306.33, up 0.76% from its previous close of 6,258.77.
The index initially strengthened further and reached an intraday high of 6,394.06 before volatility returned. The day’s low stood at around 6,264.62, highlighting the wide trading range and continuing uncertainty among investors.
The KOSPI’s early rise reflected stronger technology shares and bargain hunting following the recent market correction. BusinessKorea also reported that the benchmark reclaimed the 6,300 level at the opening as investors responded to the strong rebound on Wall Street.
KOSPI Performance
| Metric | August 10, 2026 |
|---|---|
| Opening Price | 6,306.33 |
| Previous Close | 6,258.77 |
| Intraday High | 6,394.06 |
| Intraday Low | 6,264.62 |
| Opening Gain | 0.76% |
The numbers show how quickly sentiment shifted during the session. The KOSPI moved from a modest opening gain to a much stronger intraday advance before foreign selling reduced the momentum.
The move also needs to be viewed against the backdrop of the market’s recent correction. Semiconductor stocks had come under intense pressure as investors questioned whether lofty AI-related valuations could be sustained. The latest rebound suggests that some traders are now willing to buy after the sharp decline rather than continue selling.
Korea Stock Market (KRX) Today (August 10): KOSDAQ
The secondary KOSDAQ market performed much more strongly than the KOSPI on Monday.
The KOSDAQ opened at 807.66, gaining around 1.11%, before accelerating sharply during morning trading. The index climbed to an intraday high of 846.10, with technology, biotechnology and other growth stocks attracting strong buying interest.
The stronger performance reflected renewed appetite for higher-risk shares after the recent market turbulence.
The move also showed that investors were not simply buying large-cap semiconductor companies. Capital flowed into several KOSDAQ-listed companies, particularly biotechnology, robotics and technology names.
KOSDAQ Performance
The KOSDAQ’s sharp rise came alongside a broad advance in individual stocks. More than three-quarters of KOSDAQ-listed companies were reported to be trading higher during the strong part of the session.
The buying wave was strong enough to trigger a buy-side sidecar at 9:50 a.m. KST, temporarily suspending program trading for five minutes. The measure was designed to cool the unusually rapid rise and reduce excessive short-term volatility.
This highlighted an important feature of Monday’s trading: despite the improvement in sentiment, the Korean market remained exceptionally volatile.
Korea Stock Market (KRX) Today (August 10): Samsung Electronics
Samsung Electronics became one of the key stocks to watch as investors returned to Korean technology shares.
The company’s stock closed at 234,500 won, up 1.52%, or 3,500 won, from the previous session. It opened at 236,000 won and touched a high of 238,500 won, while the day’s low stood at 231,000 won.
Samsung Electronics Share Price
| Metric | Samsung Electronics |
|---|---|
| Previous Close | 231,000 KRW |
| Opening Price | 236,000 KRW |
| Intraday High | 238,500 KRW |
| Intraday Low | 231,000 KRW |
| Closing Price | 234,500 KRW |
| Change | +1.52% |
The recovery came as investors reassessed the outlook for Samsung’s semiconductor business.
A fresh development also attracted attention. Seoul Economic Daily reported that Samsung Electronics had reached an 80% “golden yield” for its HBM4 memory production, with UBS expecting the company to potentially overtake SK Hynix in HBM4 shipments next year.
That development adds another layer to the semiconductor competition at a time when demand for memory products remains closely tied to AI infrastructure spending.
Korea Stock Market (KRX) Today (August 10): SK Hynix
SK Hynix also participated in the semiconductor rebound.
The company closed at 1,437,000 won, gaining 1.05%. The stock opened at 1,443,000 won, reached an intraday high of 1,487,000 won and touched a low of 1,418,000 won.
SK Hynix Share Price
| Metric | SK Hynix |
|---|---|
| Opening Price | 1,443,000 KRW |
| Intraday High | 1,487,000 KRW |
| Intraday Low | 1,418,000 KRW |
| Closing Price | 1,437,000 KRW |
| Daily Change | +1.05% |
SK Hynix remains one of the biggest beneficiaries of the global AI memory boom because of its position in high-bandwidth memory.
However, investors remain divided over the company’s near-term valuation. A report published Monday noted that target-price estimates from brokerages vary considerably, reflecting the unusually high uncertainty surrounding Korean semiconductor stocks after their dramatic price swings.
The stock’s recovery therefore does not automatically signal the end of the correction. Investors are still assessing whether earnings growth can justify the elevated valuations created by the AI boom.
Korea Stock Market (KRX) Today (August 10) Performance
Monday’s session demonstrated a clear split between the initial optimism and later caution.
The opening rally reflected the positive global environment, but foreign selling prevented the KOSPI from maintaining its strongest gains. Yonhap reported that Seoul shares pared their earlier advances as foreign investors sold shares during late morning trading.
This creates an important distinction for investors. The market is showing signs of stabilisation, but it has not yet established a clear long-term upward trend.
The recent correction has forced investors to reassess several assumptions behind the earlier AI-driven rally. Semiconductor valuations, corporate earnings, foreign flows and expectations for U.S. interest rates will remain critical for the next phase of trading.
Korea Stock Market (KRX) Today (August 10): Top Gainers
Several companies across the KOSPI and KOSDAQ recorded strong advances during Monday’s session.
Major Gainers
- SK Innovation: +10.77%
- S-Oil: +10.17%
- Samsung SDI: +7.49%
- Jusung Engineering: +7.36%
- EcoPro BM: +5.23%
- EcoPro: +4.76%
- Rainbow Robotics: +2.69%
KOSDAQ-listed biotechnology company Alteogen also attracted significant attention, rising around 12.95% to 344,500 won after reports that BlackRock had increased its stake and the company had exceeded first-half earnings expectations.
The breadth of the gains showed that Monday’s recovery extended beyond semiconductors. Investors also moved into biotechnology, batteries, robotics and energy-related stocks.
Korea Stock Market (KRX) Today (August 10): Top Losers
Despite the broad rebound, several smaller companies recorded steep declines.
Major Losers
- Sambo Industrial: -22.16%
- INVENIA: -17.83%
- A ONE CUBETECH: -14.92%
- Bio Protech: -14.75%
- Future Medicine: -14.18%
- AHA: -9.96%
- PANDORA TV: -9.86%
- SJ-Chem: -9.48%
The sharp moves among smaller stocks underline the continued volatility across the Korean market.
While large-cap technology stocks benefited from bargain hunting, investors continued to rotate between individual sectors and companies. This created significant differences in performance even within the same market.
Korea Stock Market (KRX) Today (August 10): What Should Investors Know?
Monday’s recovery should be viewed as a rebound attempt rather than confirmation of a new sustained bull run.
The biggest positive factor remains the improvement in global technology sentiment. Wall Street’s record performance helped investors regain confidence after the recent sell-off, while semiconductor shares found buyers at lower prices.
At the same time, foreign selling remains an important warning sign. If overseas investors continue reducing their exposure to Korean equities, the KOSPI could struggle to build on Monday’s recovery.
Investors will also watch the semiconductor sector closely. Samsung Electronics and SK Hynix remain central to the KOSPI’s direction, meaning their earnings expectations and AI-related demand could continue to influence the broader benchmark.
Another factor is the changing behaviour of retail investors. Korean regulators have recently tightened rules around leveraged single-stock ETFs, including raising the investment threshold. Reports indicate that investors have started shifting money from highly leveraged single-stock products toward broader index ETFs.
This could reduce some of the speculative pressure that contributed to the market’s extreme swings.
For now, the August 10 session points to a market attempting to recover from a sharp correction. The key question is whether Wall Street’s strength and improving semiconductor sentiment can attract enough sustained buying to overcome foreign selling and valuation concerns.
Investors should therefore watch KOSPI’s ability to hold above the 6,300 area, the performance of Samsung Electronics and SK Hynix, foreign fund flows and the broader direction of global AI stocks in the next few sessions.
