SK Hynix's Record 30% Daily Surge Caps a Week of Whiplash — and a Historic Quarter That Still Disappointed
Published on 08/01/2026 at 06:51 | Redaktion boerse-global.de
The Seoul bourse had not seen anything quite like it in nearly two decades. SK Hynix shares slammed into the exchange's daily trading limit on Friday, rocketing 29.95 percent higher to close at 1.718.000 won. It was the chipmaker's biggest single-session advance in more than 17 years — a violent reversal for a stock that, just days earlier, had been shedding value at an equally alarming clip.
From Margin Calls to a Short Squeeze
The turbulence began in late July. Between the 28th and 30th, the stock lost roughly 17 percent of its value as margin calls on leveraged positions forced liquidations across the South Korean market. The unwinding of leveraged ETFs added fuel to the fire, dragging automatic stop-loss orders into the cascade and leaving sellers scrambling for exits.
Friday's rebound, by contrast, bore all the hallmarks of a classic short squeeze, amplified by a broader stabilization in global semiconductor sentiment. The KOSPI index itself posted a historic 17.91 percent gain on the day, powered by the heavyweight memory-chip names that dominate the benchmark.
Yet even after the fireworks, the stock remains deep in the red relative to its recent peak. SK Hynix still trades 42.48 percent below the 52-week high of 2.987.000 won reached in late June. On a weekly basis, the shares are down 2.33 percent — a reminder that one spectacular session does not erase five days of pain.
Should investors sell immediately? Or is it worth buying SK Hynix?
Record Numbers, Missed Expectations
The whiplash traces back to a quarterly report that was, by any historical measure, extraordinary — and still somehow insufficient. For the second quarter of 2026, SK Hynix posted:
- Revenue: 79.32 trillion won, up 257 percent year over year
- Operating profit: 60.54 trillion won, a 557 percent surge
- Net profit: 93.92 trillion won
- Operating margin: 76 percent — a company record
All of these figures marked all-time bests for the firm. But analysts had penciled in revenue closer to 84 trillion won and operating profit around 64 trillion won, and the miss triggered a sharp sell-off on the day of the announcement. Management attributed the shortfall to timing: some high-bandwidth memory shipments slipped into later periods, while long-term supply contracts muted the immediate impact of rising DRAM prices on roughly half of total revenue.
A Fortress Balance Sheet
As the dust settled, investors redirected their attention from the income statement to the balance sheet — and found plenty to like. Cash and equivalents swelled to 88 trillion won by quarter-end, an increase of 33.6 trillion won from the prior quarter. Total debt, meanwhile, contracted to 18.6 trillion won, leaving the company with a net cash position of 69.4 trillion won.
That war chest gives SK Hynix substantial firepower for the expansion plans it has laid out. CEO Kwak Noh-jung has been unusually blunt about the road ahead, warning of a potential "memory crisis" in 2027 and predicting the most severe supply shortage in industry history. The company has confirmed a capital expenditure budget of at least $31 billion — roughly 48 trillion won — for 2026, with funds directed toward accelerating construction at its Yongin and Cheongju manufacturing clusters.
The balance sheet strength also supports a notable strategic shift. Reports indicate SK Hynix is reallocating resources toward conventional DRAM production alongside its ongoing HBM work, as acute shortages in standard memory have pushed margins in that segment to historically attractive levels. In high-bandwidth memory, where the company holds a 50 to 60 percent market share, the focus remains on the HBM4 transition, with mass production slated to begin in 2026 — a timetable the company insists it will hold, given the architecture's importance to Nvidia's upcoming AI hardware platforms.
A Nasdaq Milestone and Labor Reforms
The week's drama unfolded against a backdrop of significant corporate milestones. In early July, SK Hynix completed the listing of American depositary receipts on the Nasdaq, raising $26.5 billion — the largest amount ever raised by a foreign company in the United States. Proceeds are earmarked for next-generation manufacturing infrastructure and advanced lithography equipment.

Closer to home, management presented a proposal to the labor union on July 31 outlining a new compensation framework. The plan includes temporary salary adjustments during loss-making years and revised bonus structures, designed to give the company greater flexibility to navigate future industry cycles.
Technicals Point to Stabilization
The numbers behind the chart tell a story of recovery in progress. Year to date, the stock remains up an impressive 164.43 percent. The relative strength index, at 44.7, has exited oversold territory following Wednesday's panic. The share price has reclaimed its 100-day moving average of 1.681.145 won, though it still sits roughly 20.74 percent below the 50-day average.
For the full year, SK Hynix expects DRAM demand to grow around 25 percent, underpinned by the structural shift toward AI-centric server infrastructure. Management has guided capital expenditures toward the upper end of its 40 trillion won range, with emphasis on expanding AI memory capacity and advanced packaging — including the recently announced P&T7 fab. The combination of easing valuation pressure, a bulging cash pile, and persistent AI infrastructure demand has handed the memory heavyweight a measure of stability heading into August. Whether that stability holds will depend on whether the market's expectations — now clearly set higher than even record results can satisfy — align with the company's delivery in the quarters ahead.
