SK Hynix's Record Quarter Meets a Brutal Reality Check in Seoul
Published on 08/04/2026 at 03:44 | Redaktion boerse-global.de
The arithmetic of SK Hynix's second quarter reads like a triumph. Revenue of 79.32 trillion won. Operating profit of 60.54 trillion won — the best in company history. An operating margin of 76 percent. Year-on-year, sales climbed 257 percent while operating profit surged 557 percent.
None of it mattered on Monday. The stock closed at 1,567,000 won, down 8.79 percent in a single session, erasing most of Friday's gains when the shares had finished at 1,718,000 won. The KOSPI benchmark fell 5.12 percent as investors fled risk assets amid a volatile mix of US recession fears, Middle East tensions, and the abrupt unwinding of the Japanese yen carry trade that had been funneling liquidity into global tech names.
A Correction With Multiple Triggers
Monday's slide was the culmination of several forces converging at once. In Cupertino, Apple chief Tim Cook had floated the idea of diversifying its DRAM supplier base during an earnings call — a comment that landed with particular weight in a market where SK Hynix, Samsung Electronics, and Micron Technology collectively dominate the sector. Any move to bring in new suppliers could erode pricing power for the incumbents, and Chinese challengers like ChangXin Memory Technologies are already narrowing the technology gap in high-performance memory for AI applications.
The macro picture compounded the sector-specific worries. Geopolitical tensions in the Middle East had put investors on edge, and while the situation eased during trading, the risk-off mood persisted. Institutions used the window to lock in profits after weeks of what many considered an overheated rally.
Should investors sell immediately? Or is it worth buying SK Hynix?
Technical factors then turned a correction into a rout. More than 1.2 million leveraged retail accounts in South Korea triggered margin calls during the early August volatility, forcing brokers to liquidate positions automatically. Leveraged ETFs added fuel, their rapid unwinding generating forced selling across the entire Korean chip complex. The result was a decline that overshot what the underlying news flow alone would have justified.
The Distance From the Peak
The scale of the drawdown is stark. Over 30 days, the stock has shed roughly a third of its value. From the 52-week high of 2,987,000 won reached in late June, the shares now sit nearly 48 percent lower — 47.54 percent, to be precise. The 200-day moving average of 1,187,091 won still sits about 32 percent below the current price, a reminder that the correction has only consumed part of the prior rally.
That the sell-off came despite record results points to a deeper question investors are wrestling with: how much longer will the massive capital expenditures from major AI cloud providers continue? SK Hynix's exposure to fixed-price contracts added another wrinkle — roughly half of its second-quarter DRAM sales ran through long-term supply agreements, which prevented the company from fully capturing the recent spot-price surge. Some market participants trimmed their near-term expectations accordingly.
Building a Broader AI Story
While the market fixated on macro risks, SK Hynix used its "Future of Memory and Storage" conference in Santa Clara to push its strategy forward. Together with Sandisk, the company unveiled the first standard specification for High Bandwidth Flash, or HBF — a technology designed to sit between High Bandwidth Memory and conventional SSDs. Combining fast data transfer with NAND storage, HBF can reach capacities of up to 512 gigabytes and aims to address bottlenecks in AI inference applications.
The move signals an effort to reduce dependence on HBM3E and the upcoming HBM4. With HBF, the company gains a third pillar for the growing demand for large-scale AI infrastructure.
SK Hynix at a turning point? This analysis reveals what investors need to know now.
The balance sheet provides room to maneuver. SK Hynix ended the second quarter with 88 trillion won in cash, funding ongoing investments in the Cheongju M15X fab and the development of HBM4 samples currently being delivered to key customers.
What Comes Next
Investors now have two dates on the calendar. On Wednesday, August 5, the company becomes eligible to disclose details of a planned shareholder return program — the market expects a combination of buybacks and special dividends that could absorb a significant portion of free cash flow. Then, at the end of August, key partner companies report quarterly results, offering a clearer read on whether AI memory demand remains robust or whether Monday's sell-off was the opening act of a longer correction.
For a stock still up 141.19 percent on the year, the pain is relative. But the speed of the reversal — from record profits to an 8.79 percent single-day slide — illustrates just how quickly sentiment can turn when a crowded trade meets an uncertain macro backdrop.
