Samsung Electronics shares, which had "100,000 won electronics" in sight, turned lower intraday on the 21st. SK hynix, which topped 500,000 won early in the session, is also weak.
As of 2:08 p.m. that day, Samsung Electronics was trading at 97,950 won, down 150 won (0.15%) from the previous session. At the same time, SK hynix was down 0.51% at 483,000 won.
Samsung Electronics and SK hynix both kept setting record highs in the morning, climbing to 99,900 won and 502,000 won, respectively. In particular, expectations grew that Samsung Electronics' share price could top 100,000 won for the first time in seven years since a 50-to-1 stock split in 2018 (par value from 5,000 won to 100 won).
However, the rally appeared to stall as some investors moved to take profits after the sharp gains.
As leading blue chips lost steam, the KOSPI index, which had risen to as high as 3,893.06 early in the session, pared gains to the 3,820 level in the afternoon.
