SK Hynix's Steep Descent Puts a Red-Hot AI Trade on Trial
Published on 08/07/2026 at 10:21 | Redaktion boerse-global.de
The arithmetic is brutal. A stock that was up nearly 119 percent in June has surrendered more than half its value from its June 25 record high, closing Friday at 1,422,000 won after another 4.88 percent slide. That puts SK Hynix 52.4 percent below its peak — a staggering reversal for a company whose products sit at the very center of the artificial intelligence boom.
The sell-off has been punctuated by a technical oddity that has little to do with the chipmaker's underlying business. On the alternative South Korean exchange Nextrade, two separate blocks of shares hit the daily limit of minus 30 percent within a single week. Just eleven shares were enough to trigger the moves. The incidents have raised fresh questions about trading stability on the young platform, but they say far more about thin liquidity than about the health of SK Hynix's operations.
Record Numbers, Unimpressed Markets
The real damage began after the company's second-quarter report on July 29. SK Hynix delivered revenue of 79.3187 trillion won and operating profit of 60.5426 trillion won — the latter up 557 percent year over year, with an operating margin of 76 percent and net income of 93.9226 trillion won. Under normal circumstances, those figures would have been cause for celebration.
But analysts had been expecting more. Consensus estimates compiled by LSEG SmartEstimates called for operating profit of around 64 trillion won and revenue of 84 trillion won. The gap between delivery and expectation triggered a 9.6 percent drop on the day of the report, followed by a further 10.37 percent decline on Thursday that left the shares at 1,495,000 won. The stock remains up 130.11 percent on a twelve-month basis, but the recent trajectory has been unforgiving. The 50-day average sits at 2,140,092.50 won, meaning the shares now trade roughly 30.14 percent below that mark.

The Bull Case: Contractual Backing and Pricing Power
For those inclined to buy the dip, the fundamentals offer genuine support. SK Hynix controls more than half of the global market for high-bandwidth memory chips, with a 58 percent share in the first quarter of 2026. Crucially, a meaningful portion of that growth is already locked in — the company has secured long-term agreements with roughly ten customers, meaning the revenue stream is contractual rather than aspirational.
Pricing momentum remains favorable. Both DRAM and NAND flash prices rose quarter over quarter, driven by HBM and DRAM demand for AI servers. On the technology front, mass production of HBM4 began in the second quarter, with full-scale manufacturing expected to ramp in the second half of the year. Sample shipments of the follow-on generation, HBM4E, went out in the first half, with series production targeted for 2027. The 200-day moving average sits about 18 percent below the current price — a technical signal that the longer-term foundation remains intact despite the recent carnage.
The Bear Case: Competition and Fragile Sentiment
The skeptics question whether last year's re-rating was ever justified. Chinese memory manufacturers could expand capacity too quickly, eroding prices and compressing industry-wide returns. Market researchers warn that HBM prices may enter a correction phase after 2026 as competition intensifies and production capacity grows.
The price action itself reveals how fragile sentiment has become. The relative strength index sits at 39, approaching oversold territory, while annualized volatility of 145.71 percent suggests that calm is nowhere in sight. The Nextrade incidents add another layer of concern: as the alternative exchange gains market share rapidly in South Korea, episodes like the flash crash at SK Hynix draw regulatory attention. The worry is that such trades could undermine genuine price discovery. A portion of the recent damage is likely technical rather than fundamental — but that in itself is a risk, since thin liquidity can amplify any piece of genuine bad news.
The Capital Returns Question Hangs Overhead
Beyond the immediate price action, a separate debate is building around shareholder remuneration. SK Hynix was subject to a 25-day lock-up period following its ADR placement, which expired on August 4. On July 29, the company said it could not provide details on distribution plans due to those restrictions but would follow up after the ADR process concluded in early August. That expectation briefly lifted the stock on Wednesday.
The pressure is mounting. Reuters reported Thursday that SK Hynix and Samsung Electronics could together hold net liquidity of $263 billion by year-end — more than double Nvidia's recent net cash position. With record profits fueled by the AI boom, investors are demanding a larger share of that liquidity through dividends or buybacks.
Wall Street, for its part, remains constructive. On August 4, immediately after the lock-up expired, multiple US houses initiated coverage of SK Hynix's ADRs with positive ratings. Cantor Fitzgerald issued an Overweight with a $300 price target, implying roughly 100 percent upside. Rosenblatt, Bank of America, UBS, Needham, Stifel, Wolfe Research, and RBC Capital Markets also launched coverage with buy recommendations, with targets ranging from $200 to $320 per ADR. Barclays' Simon Coles trimmed his target from $330 to $300 on July 29 — citing lower expected average selling prices in the second quarter — but maintained an Overweight rating.
A notable signal from within: SK Group Chairman Chey Tae-won purchased shares worth 4.8 billion won on July 31.
What Happens Next
The company's own guidance points to continued growth. Third-quarter DRAM shipments are expected to rise about 10 percent quarter over quarter, with NAND bit shipments growing in the low single digits. Capital expenditures for the year should reach the high 40-trillion-won mark, and the first cleanroom phase at the Yongin facility is slated to begin operations in early 2027.
At the Flash Memory Summit in Santa Clara, SK Hynix and SanDisk jointly presented standards specifications for High Bandwidth Flash and showcased a tenth-generation 4D NAND wafer with 375 layers, promising a 2.5-fold improvement in performance per watt over the previous generation.

Two catalysts will likely determine the direction over the coming months: progress on the HBM4 ramp in the second half of 2026, and fresh signals on hyperscaler AI investment plans. Should those budgets be cut or the HBM4 ramp slip, the bear case gains considerable weight, with further downside possible toward the 200-day average at roughly 1,208,520 won. But as long as the contractual HBM business and margin profile hold up, the case for a medium-term recovery from these depressed levels remains credible.
For now, the market is caught between a company executing exceptionally well and a trade that may have simply gotten too far ahead of itself.
