The KOSPI index rose by more than 1% on the 28th, rebounding to the 2670 level due to active buying by foreigners and institutions. This marks the first time in three months since it recorded 2671.52 on February 19. Foreign investors, who had been selling Samsung Electronics for 8 consecutive trading days, reversed to net buying, focusing on large-cap stocks.
On that day, the KOSPI index closed at 2670.15, up 32.93 points (1.25%) from the previous trading day. During the session, it rose to 2692.47, hitting a year-high, but before the market closed, it reduced its gains and settled at the 2670 level.
Institutions and foreigners net bought stocks worth 743.2 billion won and 300.4 billion won, respectively. Only individuals sold stocks worth 991.1 billion won.
Samsung Electronics showed strength, rising nearly 4%. Foreign investors, who had been in a 'sell' position for 8 consecutive trading days until the previous day, bought Samsung Electronics worth 118.1 billion won. Preferred shares of Samsung Electronics also rose by 3.15%. Hanjin KAL surged 11.48% amid news that a quantity worth around 400 billion won would be released into the market in August, igniting a potential management dispute with Hoban Group, which has recently increased its equity stake.

Lee Jae-won, a researcher at Shinhan Investment Corp., noted, “As profit-taking has occurred mainly among recent leading stocks like industrials, securities, finance, and construction stocks have entered the overbought zone on the relative strength index (RSI).”
He added, “Considering that the world’s largest oncology conference, the American Society of Clinical Oncology (ASCO 2025), will open on the 30th, and NVIDIA is set to announce its first-quarter results on the 29th, it is necessary to pay attention to the fluctuations in the healthcare and semiconductor sectors.”
