Korean stock market's 12-day rally comes to an end; KOSPI is adjusting with 666 stocks showing mixed gains and losses

South Korea’s stock market experienced a clear technical correction on Tuesday after a continuous 12-day rally. The Korea Composite Stock Price Index (KOSPI) fell by 18.91 points, or 0.39%, closing at 4,885.75 points. Although the decline was modest, it ended the previous strong upward streak, reflecting increasing profit-taking pressure in the market.

According to statistics, the index has been rising for 12 consecutive trading days since the beginning of this year, with a total gain of over 16%, marking a significant increase. During Tuesday’s correction, the index briefly touched a record high of 4,935.48 points but ultimately failed to hold onto the high. Trading data showed very active turnover, with 648.7 million shares traded. There was a clear contrast between 666 stocks advancing and 228 stocks declining, indicating high market participation but with noticeable divergence. The trading volume reached 26.9 trillion won (about $182 billion), suggesting intense capital battles.

Profit-taking wave dominates the market, investor sentiment divided

The main driver of this correction was profit-taking by investors. Institutional investors sold stocks worth 6,062 billion won that day, indicating large funds began to realize gains. In contrast, retail investors and foreign investors net bought 3,527 billion won and 793 billion won, respectively, reflecting differing investment strategies among groups. The reduction in institutional holdings coupled with increased retail buying created a seesaw effect, often a sign of market sentiment divergence and uncertain future trends.

Daishin Securities analysts noted, “The semiconductor giants that led the market higher earlier this year have now reached all-time highs and are entering a short-term correction phase.” This accurately summarizes the current market situation—normal consolidation after a strong rally.

Chip and auto stocks retreat collectively, utilities rise against the trend

In terms of sector performance, the main drivers that previously pushed the market higher showed noticeable declines. Semiconductor stocks generally corrected; Samsung Electronics fell 2.75% to 145,200 won, and SK Hynix, another chip giant, declined similarly from 743,000 won by 2.75%. The auto sector also declined, with Hyundai Motor dropping slightly by 0.21% to 479,000 won, while its subsidiary Kia fell more sharply by 3.3% to 163,900 won.

Contrasting sharply with most stocks, state utility company Korea Electric Power Corporation (KEPCO) surged 16.16% to 65,400 won. This phenomenon reflects growing investor preference for stable assets amid rising risk aversion.

Rising geopolitical risks intensify market correction

The market correction is also closely related to changes in the global political and economic landscape. As U.S. President Donald Trump’s ongoing discussions about Greenland continue to ferment, geopolitical risks appear to be escalating. Global markets have entered a correction cycle, and Korea’s market pullback is a reflection of this global trend.

Additionally, the won-dollar exchange rate also declined slightly, with the rate at 1,478.7 at 3:30 pm, down 5 won from the previous trading day. This exchange rate movement further confirms cautious market sentiment.

The end of the 12-day rally does not mean a complete reversal of the upward trend but rather a normal consolidation at high levels. Based on differentiated investor actions and sector divergence, the market has shifted from a previous unilateral rise to a structural adjustment phase, adding more variables and opportunities for future developments.
