[Edaily Reporter KIM YOON-JEONG ] Just one day after SK Group Chairman Choi Tae-won purchased SK hynix shares on the open market, his paper gains exceeded 1.2 billion won. As he demonstrated his commitment to responsible leadership by personally buying shares that had recently plummeted, the stock price rebounded sharply, causing his investment returns to grow rapidly.

According to MP Doctor on the 31st, as of 10:27 a.m., SK hynix(000660)is trading at 1,687,000 won, up 365,000 won (27.61%) from the previous trading day.
Earlier, SK hynix disclosed that Chairman Choi had purchased 3,620 shares of SK hynix common stock on the open market on the previous trading day (the 30th). The average purchase price was 1,353,677 won per share, for a total purchase amount of 4,860,310,000 won.
As SK hynix’s stock price surged by more than 27% during the trading session today, Chairman Choi’s investment returns also grew rapidly. Based on the current stock price, the market value of Chairman Choi’s holdings has increased to approximately 6.107 billion won. His paper gains in a single day amount to about 1.207 billion won.
This purchase is reportedly part of his commitment to responsible management, based on the assessment that SK hynix’s stock price—which had recently plummeted—was excessively undervalued relative to the company’s intrinsic value. The decision to limit the purchase amount to less than 5 billion won is interpreted as a move to swiftly demonstrate his commitment to responsible management without undergoing the prior disclosure procedures required for transactions exceeding 5 billion won.
This marks the first time Chairman Choi has purchased SK hynix shares on the open market. Earlier, on the 17th, at the Jeju Forum hosted by the Korea Chamber of Commerce and Industry, Chairman Choi emphasized the growth potential of the semiconductor industry in the age of artificial intelligence (AI) and called for long-term investment.
At the time, when asked about the outlook for SK hynix’s stock price, he said, “Don’t buy and sell SK hynix stock; just hold onto it.”
He went on to explain, “Memory will inevitably continue to be used, and the reason SK hynix and SamsungElectronics’ stock prices have risen from last year through this year is because they recognized this trend,” adding, “Stock prices can skyrocket when expectations are high, but they can also plummet sharply if things don’t look quite right.”
He continued, “Given the current situation, memory will continue to be in demand, so over time, the trend will be upward. However, I cannot predict what will happen next month.” He added, “For this type of stock investment, just hold on to your shares. Don’t buy and sell—we believe that’s the best way to preserve your assets.”
