KOSPI closed at 6797.70 on the 22nd, up 49.75 points (0.74%), after triggering a buy-side circuit breaker during an intraday surge past 7100. The index retreated over 300 points from its session high despite foreign investors net purchasing ₩2.6299 trillion, as institutions and retail investors sold a combined ₩2.6139 trillion. The failure to sustain the 7000 level following a strong programmatic buy signal is considered unusual, reflecting heavy supply above 7000 and weak market internals, according to market observers cited in the Financial News report.
Foreign Investors Net Buy ₩2.6 Trillion While Institutions and Retail Sell Equivalent Amount
Foreign investors net purchased ₩2.6299 trillion in the securities market on the 22nd, according to the Korea Exchange. Institutions net sold ₩1.3963 trillion and individuals net sold ₩1.2176 trillion during the same session. The combined institutional and retail selling totaled ₩2.6139 billion, nearly matching the foreign inflow.
Financial investment entities led the institutional selling with ₩975.8 billion in net sales. Private equity funds sold ₩257.4 billion, investment trusts sold ₩109.6 billion, and pension funds recorded net sales of ₩70.6 billion.
Semiconductor Stocks Surrender Intraday Gains as Profit-Taking Emerges
Samsung Electronics rose as much as 6.6% intraday but closed with a gain of only 0.6%. SK Hynix surged 9.3% during the session before turning negative with a 0.3% decline at the close. The semiconductor sector's inability to hold gains reflected stronger profit-taking pressure in the afternoon compared to the morning buying momentum, according to the source.
Kang Jin-hyuk, senior researcher at Shinhan Investment & Securities, stated that "foreign cash inflows and semiconductor strength drove the index past 7100 intraday, but institution-led selling resulted in a strong-start-weak-finish pattern."
Market Structure Shows Heavy Supply Above 7000 Level
The buy-side circuit breaker triggered on the 22nd marked the second consecutive day of such an event and the 20th occurrence in the current year. A securities industry official quoted in the source noted, "The key point is not the circuit breaker itself but the flow afterward. A buy-side circuit breaker signals strong upward pressure in the futures market. However, on this day, even after the breaker triggered and KOSPI broke 7100, the index failed to hold those gains."
The pattern suggests that profit-taking supply waiting above 7000 exceeded new buying interest at those levels. The ₩2.6 trillion foreign inflow absorbed the combined institutional and retail selling but did not generate additional upward momentum.
Lim Jung-eun, researcher at KB Securities, stated, "Major earnings announcements are scheduled, including Hyundai Motor and Samsung Biologics domestically, and Alphabet and Tesla in the US. Alphabet's results will serve as a key variable influencing sentiment toward AI semiconductor-related stocks."
