\"SKSK Group Chairman Chey Tae-won speaks at the San Francisco AI Summit held in San Francisco, U.S., on the 24th (local time) this month. News1<\/p>\n

SK hynix (000660.KS) shares that SK Group Chairman Chey Tae-won purchased directly on the open market for the first time are estimated to have generated a valuation gain of more than 1 billion won in just one day. As U.S. artificial intelligence (AI) chip stocks surged across the board, SK hynix jumped more than 27% in early trading, and top shareholder SK Square also soared to its daily price limit.<\/p>\n

According to the Korea Exchange, as of 10:45 a.m. on the 31st, SK hynix traded at 1,630,500 won, up 23.34% from the previous session. During the session, it climbed as high as 1,744,000 won, approaching the upper limit. SK Square, the top shareholder holding a 20% stake in SK hynix, also hit its daily limit at 1,038,000 won, up 29.91%.<\/p>\n

The surge means Chairman Chey’s investment, made through a direct open-market purchase of SK hynix common shares the previous day, recorded a large valuation gain in just one day. According to the Financial Supervisory Service’s electronic disclosure system, Chey purchased 3,620 shares of SK hynix common stock on the open market the previous day. Based on the previous day’s closing price of 1,322,000 won, a simple calculation against the session’s high of 1,714,000 won on the day yields an estimated valuation gain of approximately 1.419 billion won. However, the actual execution price on the open market was not disclosed, and the actual valuation gain may vary depending on SK hynix’s closing price for the day.<\/p>\n

The market interprets the purchase as a signal of confidence in the growth potential of the AI memory business and SK hynix’s long-term competitiveness. This marks the first time Chey has directly purchased SK hynix shares under his own name. Until now, Chey had held stakes indirectly through SK and SK Square.<\/p>\n

The rebound was led by strength in U.S. chip stocks. In overnight New York trading, Microsoft (MS) surged 15.51% after announcing earnings that beat market expectations and plans to expand AI investment. This revived expectations for expanded AI investment, sending the Philadelphia Semiconductor Index (SOX) up more than 8%. Major chip stocks also rallied across the board, including Micron (18.36%), AMD (13.00%), SanDisk (25.99%), and Intel (11.30%).<\/p>\n

The tailwind from the United States carried over directly to domestic memory chip stocks. As expectations for increased demand for high-bandwidth memory (HBM) driven by expanded AI investment came back into focus, buying flowed in centered on SK hynix. Rising expectations for SK hynix’s corporate value also lifted the shares of top shareholder SK Square.<\/p>\n
