On August 14, SK hynix rose 3.4% in regular trading, reaching $170.2 per share with turnover of $986 million, as multiple catalysts converged to propel the stock higher.

On the news front, SK hynix Chairman Chey Tae-won announced plans to invest $720 billion to expand AI memory production capacity in both South Korea and the United States, underscoring the company's long-term strategic commitment to the high-bandwidth memory (HBM) segment. The chairman also warned that next year could see the most severe memory shortage in recent years, reinforcing supply-tightening expectations.

Separately, SK hynix has spent over a month actively scouting potential U.S. sites for a front-end memory wafer fab, converting its previously vague stance into concrete commercial action in response to AI chip customers demanding supply chain localization. Additionally, Singapore sovereign wealth fund Temasek is reportedly planning its first direct investment in Korean equities, with SK hynix among its targets. The company's first-half revenue from NVIDIA exceeded 17 trillion won, representing approximately 13% of total sales, highlighting its dominant position as an AI memory supplier.
