SK Hynix's 23% Friday Surge: A Market Recalibration After a Brutal Month
Published on 08/02/2026 at 19:01 | Redaktion boerse-global.de
The memory-chip maker's shares have just delivered one of the most violent reversals in recent memory — a 22.63% single-day advance that recouped a meaningful slice of the prior month's losses. SK Hynix closed Friday at 1,718,000 won, a dramatic swing that underscores just how quickly sentiment can flip in the semiconductor trade when the right catalysts line up.
The rally followed a punishing stretch that stripped nearly a third of the stock's value. The 32.89% drawdown had been fueled by a combination of post-earnings disappointment and broader anxiety about whether the artificial-intelligence infrastructure boom was starting to cool. Friday's move, however, suggested investors were ready to reassess.
The Catalysts Behind the Turnaround
Two developments did the heavy lifting. First, South Korea's trade ministry published preliminary July export figures that blew past even optimistic forecasts: semiconductor shipments jumped 179% year-over-year to $41.01 billion, the second-highest monthly total on record behind June. Memory chips alone accounted for roughly 41.5% of the country's total exports, with enterprise SSDs — the storage workhorses inside AI data centers — seeing their sales value climb more than 500% from a year earlier.
Second, SK Hynix confirmed a multi-year partnership with Nvidia for next-generation AI memory chips. The deal, tied to the more than $500 billion initiative for AI factories and memory development, reinforced the company's position as the primary supplier for Nvidia's accelerator lineup.
Should investors sell immediately? Or is it worth buying SK Hynix?
Overseas investors responded with conviction. Foreign buyers snapped up a record 7.2 trillion won of KOSPI shares on Friday — the largest single-day inflow ever registered — with SK Hynix at the center of the buying wave.
The Earnings Paradox
The Friday surge marked a sharp pivot from the market's initial reaction to the company's second-quarter report on July 29. The numbers were, by any historical measure, extraordinary: operating profit of 60.54 trillion won, up 557%, on record revenue of 79.32 trillion won, with an operating margin of 76%. Net income of 93.92 trillion won was inflated by a one-off gain of 62.17 trillion won from the sale of the Kioxia stake.
Yet the stock initially fell. The culprit was a modest miss on the top line — revenue came in slightly below the consensus estimate of around 84 trillion won, while operating profit also trailed the roughly 64 trillion won that ambitious analysts had penciled in. Investors punished the shortfall rather than celebrating the underlying strength.
Friday's action suggests a recalibration. The market's attention has shifted to execution: HBM4 mass shipments began in the second quarter, production for the second half of 2026 is already ramping, and the key question is whether the company can resolve the delivery delays flagged in its earnings report and hit its bit-growth targets for the new memory generation.
Where the Stock Stands
Despite the explosive rebound, the shares remain 42.48% below their 52-week high of 2,987,000 won set on June 25. The stock is still 20.74% under its 50-day moving average of 2,167,507.68 won, and the gap to the 200-day average stands at a wide 45.43%. A 14-day RSI of 44.7 suggests the rally hasn't pushed the stock into overbought territory, leaving technical room for further upside.
The bull case rests on SK Hynix's commanding position in high-bandwidth memory. According to the prospectus for its recent Nasdaq listing, the company holds a 56.4% share of the global HBM market. That leadership could face pressure in 2027 as competitors accelerate their HBM4 certifications, but for now the company remains the dominant force in the most profitable corner of the memory business.

The bear case is equally visible. Annualized 30-day volatility sits at a staggering 152.53%, a figure that speaks to a stock prone to violent swings in both directions. The capex plan of at least 45 trillion won for 2026 — up 50% from the prior year — raises the stakes on achieving high manufacturing yields. And the revenue miss showed how quickly delivery recognition issues can rattle the share price, even in a robust demand environment.
What to Watch
For the coming weeks, the immediate technical question is whether the stock can hold above the 1,700,000 won level. Beyond that, investors will be monitoring qualification updates for HBM4 and further details on the new M15X production line. The stock's year-to-date gain of 164.43% reflects how richly the market has rewarded the company's profitability, and SK Group Chairman Chey Tae-won recently added 3,620 shares worth roughly 4.9 billion won — a vote of confidence from the top.
The broader backdrop remains supportive. Microsoft's quarterly results exceeded expectations, with robust cloud growth and reaffirmed 2026 investment plans, easing fears that the massive AI capital expenditure cycle might stall. As long as US tech giants keep spending on AI infrastructure, SK Hynix stands to benefit. But with volatility at these levels, the market's mood can shift as quickly as it did this week — in either direction.
