SK Hynix’s Balancing Act: NAND Milestone Meets Tighter Leverage as Nasdaq Looms
14.06.2026 - 08:16:04 | boerse-global.de
The South Korean chipmaker has been on a tear, but the forces driving its rally are shifting. SK Hynix closed Friday at 2,150,000 won, up 2.33% on the day, extending a year-to-date surge of roughly 218%. Beneath the surface, a complex picture is emerging: a technological breakthrough in NAND flash, a pending US listing that could unlock billions, and a simultaneous squeeze from Wall Street banks on the very leverage that fuelled the stock’s ascent.
Industry research firm TrendForce confirmed this week that SK Hynix has completed verification of a 375-layer NAND design. Mass production is slated to start by the end of 2026, with the company planning to convert existing fabrication capacity. The technical challenge is formidable: at such dense stacking, resistance and signal delay mount, so SK Hynix is introducing molybdenum into part of the word-line structure to mitigate both. Notably, the original target was pegged at 400 layers, but the company has revised the number downward, acknowledging the manufacturing complexity of pushing beyond that frontier. The move would still give SK Hynix a commanding lead over rivals — Samsung only began mass production of 286-layer NAND in April 2024, while Kioxia’s 218-layer product dates back to 2023. For investors, the NAND story adds a new dimension to SK Hynix’s AI narrative, positioning it as a broad advanced-memory player rather than just a high-bandwidth memory (HBM) play.
Yet even as the technology roadmap extends, the financial mechanics of the rally are being recalibrated. Bloomberg reported on June 12 that Citi, JPMorgan, and Goldman Sachs have raised the financing costs for hedge funds using swap structures to bet on SK Hynix and Samsung Electronics shares. Morgan Stanley has gone further, reportedly rejecting new swap requests for both Korean stocks outright. Banks are also limiting the size of new positions and tightening counterparty credit checks. Swap financing costs for SK Hynix and Samsung have jumped to the secured overnight financing rate (SOFR) plus 300 basis points — as high as 11% — compared with roughly 100 to 200 basis points over SOFR in early May. This tightening doesn’t affect the company’s operational health, but it alters the demand composition behind the stock, potentially making it more vulnerable to sudden shifts in sentiment.
Should investors sell immediately? Or is it worth buying SK Hynix?
The operational backdrop remains robust, however. In the first quarter, SK Hynix posted quarterly revenue exceeding 50 trillion won for the first time, with record operating profit driven by strong demand for HBM, server DRAM modules, and enterprise SSDs for AI infrastructure. Last week, the company and Nvidia announced a multi-year technology partnership to develop next-generation memory solutions for platforms including the Vera Rubin AI supercomputer, Vera CPUs, and Jetson Thor for robotics. These fundamentals continue to underpin the bull case.
Adding another layer of complexity is the planned Nasdaq listing. Reuters also reported on June 12 that SK Hynix has chosen the Nasdaq over the New York Stock Exchange for its US debut. SEC clearance could come as early as the week of June 22, with the actual listing potentially in August. The company confidentially filed for a US listing in March, and the offering could raise up to $14 billion. That would open the stock to a new pool of institutional buyers, partially offsetting the chill from the swap tightening and potentially broadening long-term ownership.
For now, the technical picture offers no clear direction. The relative strength index (RSI) at 58.4 points to neither overheated nor oversold territory. But the annualized 30-day volatility of 102% — or over 100%, according to a separate reading — underscores how quickly position changes can move the shares. The stock remains about 10% below its all-time high of 2,407,000 won set in early June. With the SEC decision on the ADR listing expected around June 22, the coming week could prove pivotal in determining which of these cross-currents gains the upper hand.
