SK Hynix Pockets Vera Rubin Deal, Signals ADR Debut, Yet Market Punishes Stock With 10% Plunge

Memory giant SK Hynix suffered its worst single-day loss in months after a Nvidia supply deal and ADR announcement, as profit-taking and external headwinds offset a 205% YTD gain.

The disconnect between corporate milestones and market reaction has rarely been wider at SK Hynix. The South Korean memory giant secured a key role supplying chips for Nvidia’s upcoming Vera Rubin AI platform and outlined plans to list American depositary receipts on Wall Street — only to watch its shares suffer their worst single-day loss in months.

The stock closed at 2,070,000 won on Friday, down 9.92% from the previous session. The selloff erased roughly 57 billion dollars in market value and pulled the shares 14% below their 52-week high of 2,407,000 won, set on June 2. Yet even after the rout, the stock still shows a 205.76% gain year-to-date and a near-30% advance over the past 30 days.

Investors attributed the meltdown to a one-two punch of external headwinds. A weakening South Korean won weighed on the broader market, while a sharp decline in US tech megacaps spilled over into Asian trading. Profit-taking after an extraordinary rally also played a role: the shares had more than tripled since the start of 2026 and briefly pushed the company’s market capitalization above 1 trillion dollars just days earlier.

Inside the company, the operational narrative remains overwhelmingly bullish. SK Hynix has locked in a supply deal for Nvidia’s new Vera Rubin architecture, cementing its dominance in high-bandwidth memory (HBM). Management has also raised capital expenditure for 2026 to expand chip-packaging capacity, betting that demand will outstrip supply for years. Next-generation HBM4E samples are slated to go to customers in the second half of the year, with commercial production expected in 2027.

Those strategic moves underscore a broader industry upswing. Combined memory revenue at SK Hynix, Samsung Electronics, and Micron reached approximately 114.9 billion dollars in the first quarter of 2026, up 77% sequentially. Second-quarter revenue is on track to exceed 170 billion dollars as memory prices climb and AI-driven demand tightens supply.

SK Hynix’s own first-quarter results reflect the tailwinds: revenue of 52.5763 trillion won, operating profit of 37.6103 trillion won, and net income of 40.3459 trillion won, all lifted by sales of high-margin products. The company is also preparing to issue ADRs in the United States this year, a move that would give large institutional investors a direct channel into the stock.

The market now faces a testy few days ahead. Nvidia CEO Jensen Huang visited South Korea on June 5 and said he had brought “a lot of business” and “some surprises,” though he did not confirm a specific order. He highlighted robotics as the next big sector for the country and planned meetings with SK Hynix, Samsung, Hyundai, LG, and Naver.

On the macro front, the US consumer price index for May lands on June 10, followed by the producer price index a day later. Those releases will shape expectations for the Federal Reserve’s next rate decision on June 18, and they arrive during the Fed’s blackout period — meaning markets must digest the data without fresh commentary from policymakers.

For SK Hynix, the combination of extreme valuation, a sudden technical breakdown, and a data-driven week creates an unusually fragile setup. The stock closed 42% above its 50-day moving average, and 30-day annualized volatility stood at 85.89%, both signals that the recent price action is prone to violent reversals. The company’s fundamentals have rarely looked stronger; the question now is whether that strength can stabilize a market that just delivered a brutal wake-up call.
