SK Hynix Inc stock (KR7000660001): valuation in focus as memory cycle and AI demand drive South Korean chip giant

SK Hynix shares in South Korea remain closely watched as investors weigh rich valuation metrics against strong AI-driven memory demand and the latest quarterly figures from the KRX-listed chipmaker.

SK Hynix Inc shares on the Korea Exchange remain in the spotlight on 05/29/2026 as investors assess the South Korean memory specialist's valuation metrics in light of strong demand from artificial intelligence data centers and the latest quarterly earnings recovery.

The stock is listed on the Korea Exchange (KRX) under the ticker 000660 in South Korea, where it is a key constituent of the KOSPI index and widely followed by domestic institutions and retail investors. According to Korea Exchange data, SK Hynix has been one of the most actively traded semiconductor names in Seoul during 2026 as markets focus on dynamic random access memory (DRAM) and high bandwidth memory (HBM) exposure into the global AI infrastructure cycle.

In its most recent earnings release for the first quarter of 2026, SK Hynix reported that operating profit rebounded sharply from the prior-year loss as DRAM and NAND prices recovered on the back of tight supply and AI-related server demand. Company disclosures show that revenue and profitability improved significantly compared with the memory downturn in 2023, when excess inventories and weak PC and smartphone demand weighed on results. Management highlighted sustained momentum in high-performance DRAM products used in AI training and inference workloads in data centers, an area where SK Hynix positions itself as a leading supplier.

The stock's current pricing on the Korea Exchange reflects investors' expectations that the memory upcycle and AI-driven HBM demand will continue to support earnings through 2026 and 2027. Local financial media in South Korea regularly note that SK Hynix has become one of the flagship AI-related plays on the KOSPI alongside Samsung Electronics, with foreign inflows tracking global semiconductor sentiment. For German-based investors, the shares can also be accessed via secondary trading venues such as Tradegate or Frankfurt, where prices are quoted in euros and track the primary KRX line.

Valuation metrics and multiples for SK Hynix Inc

Investors looking at SK Hynix on 05/29/2026 are focusing on valuation ratios that have expanded along with the recovering memory cycle and the strong narrative around AI-related demand. Market data from the Korea Exchange and major financial information providers indicate that, based on the latest twelve-month earnings reported in the first quarter of 2026, SK Hynix trades at a markedly higher price-to-earnings multiple than it did during the trough of the cycle in 2023, when the company posted net losses and valuation was better assessed on a price-to-book basis. As profitability has returned, the forward P/E multiple has moved into a range that reflects both cyclical recovery and optimistic expectations for sustained HBM demand from global cloud and AI players.

Beyond P/E, enterprise value to EBITDA multiples are also closely watched given the capital-intensive nature of the memory business and SK Hynix's significant fabrication plant investments in South Korea and overseas. The latest investor presentations from SK Hynix emphasize substantial capital expenditure to expand HBM and advanced DRAM capacity, which feeds into valuation discussions around long-term returns on invested capital and the sustainability of margins through the next phases of the cycle. While the company has historically paid dividends, payout levels and yields vary with earnings, and recent years of restructuring the balance sheet and funding capacity expansion have influenced its dividend policy, which investors incorporate when comparing SK Hynix to global peers in the memory and broader semiconductor sector.

Conclusion

SK Hynix remains one of South Korea's most closely followed semiconductor names as the stock reflects a recovery in memory pricing and heightened expectations around AI-related demand for advanced DRAM and HBM products. The latest quarterly figures show a sharp turnaround in profitability compared with the 2023 downturn, which is now embedded in richer valuation multiples on the Korea Exchange as of 05/29/2026. How earnings evolve across upcoming quarters, and whether capital expenditure on capacity expansion delivers the anticipated returns, will be key in determining whether current valuation levels are sustained in the context of the global memory and AI infrastructure cycle.
