It wasn't just 4.9 billion won... The logic behind Choi Tae-won's 'responsible management' reflected in SK hynix

SK Group Chairman Chey Tae-won bought 3,620 common shares of SK hynix on the 30th for about 4.93 billion won in open-market trading.

It is his first direct holding in SK hynix, and is being read as a show of personal commitment and responsible management.

The purchase came just under the 5 billion won disclosure threshold by about 99.69 million won, avoiding prior disclosure requirements.

Markets view the move as a strong signal of confidence in SK hynix and the wider group, with potential implications for further buying.
