SK Hynix's U.S.-listed American depositary receipts rose 7.05% to a record $198.63 on Sept. 9, after touching $199.87 intraday and climbing about 33% above their July 10 IPO price of $149. Investors are betting that shortages of DRAM and NAND flash memory will persist through 2027 as artificial-intelligence infrastructure expands demand for high-bandwidth memory (HBM). UBS analyst Timothy Arcuri said both markets would remain in short supply through 2027, while TechInsights Chief Strategy Officer Dan Kim rated current memory-market overheating at 8 out of 10 and said conditions would remain at that level until at least the end of 2027. Bank of America upgraded the ADRs to buy and set a $250 target, implying about 26% upside from the Sept. 9 close. SK Hynix's broader strategy includes HBM leadership, the development of High Bandwidth Flash for AI inference, and the use of Nvidia's AI tools in chip design and manufacturing. Its South Korean shares later gave back early gains on Sept. 10 as the KOSPI weakened, despite continued buying through foreign brokerage desks.
