In South Korea’s regular session on August 14, 2026, the KOSPI closed at 6,977.94, up 164.60 points, or 2.42%, from the previous session. The KOSPI rose as high as 7,010.86 intraday but finished below 7,000, while the KOSDAQ gained only 0.38% in the same session, widening the performance gap between the two indexes to 2.04 percentage points.

KOSPI Gives Back Part of Its Gains After Crossing 7,000
| Index | August 14, 2026 Regular-Session Close | August 14, 2026 Change |
|---|---|---|
| KOSPI | 6,977.94 points | +164.60 points (+2.42%) |
| KOSDAQ | 864.65 points | +3.28 points (+0.38%) |
The KOSPI opened the August 14, 2026 regular session at 6,995.67, traded between 6,848.43 and 7,010.86, and closed at 6,977.94. The difference between the session high and low was 162.43 points, while the close was 17.73 points below the open and 32.92 points below the high. The index closed higher than in the previous session but did not maintain its highest intraday level through the close. KOSPI closing data
The KOSDAQ opened at 868.07 on August 14, 2026, rose as high as 879.29 intraday, fell as low as 845.41, and closed at 864.65. Its intraday range was 33.88 points, and the close was 3.42 points below the open and 14.64 points below the high. KOSDAQ closing data
The editorial interpretation based on the closing data is that the gains on August 14, 2026 were much stronger in the KOSPI than in the KOSDAQ. The fact that both indexes rose, or the gap between their percentage gains alone, is not enough to conclude that a particular sector or news event caused the divergence.

Samsung Electronics closing data Historical analysis of the individual stock is available at the Samsung Electronics stock hub.
The editorial interpretation is that all tracked stocks rose on August 14, 2026, but their closing positions differed. Hyundai Motor and Samsung Electronics closed 3,000 won and 3,500 won below their respective session highs, while SK Hynix and SK Square finished 55,000 won and 54,000 won below their respective highs. These closing positions alone cannot establish the cause of selling pressure or the stocks’ subsequent direction.
Foreign Net Buying and the Background Cited in News Reports Should Be Distinguished
Investor flow data for August 14, 2026 showed foreign investors as net buyers of 30,387 hundred million won. Individual investors were net sellers of 19,819 hundred million won in the same session, while institutions were net sellers of 10,300 hundred million won. Foreign net buying occurred alongside the KOSPI’s 2.42% gain, but the simultaneous moves alone cannot establish that foreign investor flows directly caused the index to rise.

Yonhap News reported that a favorable mood stemming from easing inflationary pressure in the United States provided the backdrop for the South Korean market’s performance on August 14, 2026. This was the causal explanation presented in the article; the domestic regular-session closing data itself does not prove that causal relationship. Original Yonhap News article
An early-session report from the same trading day said the KOSPI had reclaimed 7,000 intraday shortly after the open. The August 14, 2026 regular-session data did show a KOSPI high of 7,010.86, but the index closed at 6,977.94. The report’s early-session observation and the final close refer to different points in time and should be distinguished. Original early-session article
Three Items to Watch in the Next Regular Session
-
It will be important to see how the KOSPI changes the 32.92-point gap between its August 14, 2026 close of 6,977.94 and that day’s high of 7,010.86 at the next regular-session close. For the KOSDAQ, the comparison point is the 14.64-point gap between its August 14, 2026 close of 864.65 and high of 879.29.
-
The next regular-session close will show whether the 5.82-percentage-point gap between Hyundai Motor’s 8.24% gain and the KOSPI’s 2.42% gain on August 14, 2026 widens or narrows. The relative performance of SK Hynix at 3.26%, SK Square at 3.31%, and Samsung Electronics at 2.43% should also be monitored.
-
It will be important to check whether the August 14, 2026 investor flow pattern—foreign net buying of 30,387 hundred million won, individual net selling of 19,819 hundred million won, and institutional net selling of 10,300 hundred million won—continues in the next regular-session data. This is only a point of comparison and is not a basis for predicting the direction of the index or individual stocks in the next regular session.
