SK Group Chairman Chey Tae‑won bought 3,620 ordinary shares of SK Hynix on the open market, valued at about 4.79 billion won. The purchase, disclosed in a filing on July 31, is his first personal stake in the chipmaker; previously he exercised control through the group’s largest shareholder, SK Square. The shares had fallen more than 50 % from a record high of 2.99 million won on June 25 to 1.32 million won on the day of the purchase. After the filing, SK Hynix stock jumped roughly 25 % to around 1.66 million won, giving Chey an estimated paper gain of 10‑13 billion won. The rally was reinforced by a broader semiconductor rebound, with the Philadelphia Semiconductor Index rising 8.19 % on the same day. Analysts interpreted the move as a signal of confidence and responsible‑management intent, prompting a surge in investor sentiment toward Korean memory stocks.
