SK Hynix's Two-Track Rally: Washington Diplomacy Meets a Fast-Forwarded DRAM Roadmap
Published on 09/07/2026 at 14:11 | Editorial boerse-global.de
The South Korean memory maker's shares are being pulled in two directions at once — a trade-policy whipsaw from Washington and a manufacturing transition that is running ahead of schedule. Both forces converged on Monday to produce the stock's sharpest advance in weeks, though for distinctly different reasons.
The Tariff Pendulum Swings Back
SK Hynix climbed 7.8 percent to close at 1,776,000 won on Monday, with Reuters reporting that ongoing negotiations between Seoul and Washington over semiconductor investment — conducted within the framework of bilateral tariff talks — were the primary catalyst. The move marked a rapid reversal of fortune: just days earlier, a separate Reuters-based report had flagged fresh US tariff threats targeting South Korean chipmakers, reviving pressure on the sector after Washington appeared to have shelved its semiconductor-specific duties.
The whiplash underscores just how sensitive the equity has become to political signals emanating from the trade talks. Market observers were quick to note that no fresh company-specific news drove the rally — instead, they pointed to persistently robust demand for high-bandwidth memory chips as the underlying tailwind.
That characterization aligns with the picture emerging from SK Hynix's latest preliminary quarterly results, which media reports put at 79.32 trillion won in revenue and 60.54 trillion won in operating profit, both attributed to the artificial intelligence memory boom.

A Manufacturing Transition Accelerates
Beneath the tariff headlines, a quieter but arguably more consequential story is unfolding on SK Hynix's production lines. The company is transitioning to its latest DRAM manufacturing technology — the 1c process node — considerably faster than analysts had anticipated, positioning it for the next generation of memory chips that will power AI accelerators.
The share of 1c-DRAM in total output is projected to climb from 13 percent in the second quarter to 24 percent in the third and 34 percent in the fourth quarter. By the first quarter of 2027, the 1c process is expected to overtake the current 1b standard as the company's primary manufacturing method, with 35 percent versus 33 percent respectively.
The timing is deliberate. SK Hynix is deploying 1c technology specifically for its upcoming HBM4E generation — the high-bandwidth memory chip that serves as a critical component for AI accelerators from Nvidia and others. In June, the company shipped samples of 12-layer HBM4E chips to major customers, featuring a data rate of 16 gigabits per second and more than 20 percent better energy efficiency than the previous generation. SK Hynix is widely regarded as Nvidia's principal HBM supplier.
The Competitive Landscape Shifts
The accelerated 1c push is also a direct response to competitive pressure. While SK Hynix is reserving the new manufacturing technique for HBM4E, Samsung Electronics is already using it for the current HBM4 generation — running at 11.7 gigabits per second — which entered mass production in February.
Samsung's own 1c share stood at 16 percent in the second quarter, while Micron reached 19 percent. Both rivals currently lead SK Hynix on this particular manufacturing step, even as the South Korean company maintains its overall lead in the HBM market.
In the broader DRAM market, however, the balance is shifting toward Samsung. Industry revenue in the second quarter of 2026 jumped roughly 59.5 percent quarter-on-quarter to $154.73 billion, driven by demand that is visibly outstripping supply. SK Hynix generated $38.59 billion in this segment, up nearly 38 percent, holding a 24.9 percent market share. Samsung posted $60.98 billion for a 39.4 percent share — the gap between the two conglomerates has widened considerably.
The Indiana Card in Trade Negotiations
The tariff discussions touch directly on SK Hynix's investment plans in the United States. Just last Wednesday, the company held a ceremonial groundbreaking for its advanced packaging manufacturing and research facility for AI memory chips at Purdue Research Park in Indiana. The project, announced in 2024, carries a price tag of more than $4 billion and will mark SK Hynix's first US production site for AI memory. Shipments of next-generation HBM memory are slated to begin from the facility in the second half of 2029.
Such location decisions frequently become bargaining chips in tariff negotiations, serving as evidence of local value creation. That dynamic likely explains why progress in the Seoul-Washington talks moves the stock so immediately.
Seoul's AI Ambitions Add Fuel
Political tailwinds extend beyond the bilateral talks. South Korea has proposed a record budget of $597 billion for 2027 to accelerate artificial intelligence investment, according to Reuters, with Samsung Electronics and SK Hynix identified as beneficiaries of the unprecedented profits flowing from HBM demand.
A Stock Caught Between Signals
Despite Monday's robust gain, SK Hynix still trades 41 percent below its 52-week high of 2,987,000 won, reached in June. At the same time, the shares sit 35 percent above their 200-day average of 1,314,812.28 won — evidence that the broader uptrend remains intact despite recent turbulence. Annualized volatility stands at a hefty 130 percent, a reflection of the political uncertainty surrounding the tariff dialogue.
The stock's year-to-date advance stands at 174 percent, though it remains roughly 2 percent below its 50-day moving average and a considerable distance — about 40 percent — from June's record. The September low, by contrast, is far in the rearview mirror.
For investors, the picture is one of competing narratives: short-term swings driven by every twist in trade negotiations, set against a company that is methodically aligning its technology roadmap with surging AI memory demand — even as Samsung claims a larger slice of the overall DRAM pie. The central question is whether the Seoul-Washington talks translate into concrete commitments that give SK Hynix the planning certainty its multibillion-dollar US investments require. Until then, the stock appears destined to remain sensitive to every headline from the negotiating table.
