SK Hynix Rides Micron’s Coattails as Investors Brace for a Pivotal Earnings Call
Published on 07/22/2026 at 03:31 | Redaktion boerse-global.de
The South Korean memory-chip heavyweight hasn’t issued a single press release this week, yet its shares just notched their biggest single-day gain in a month. SK Hynix closed Tuesday at 1,836,000 won, up 4.08 percent, as a blockbuster earnings report from US rival Micron Technology sent shockwaves through the entire semiconductor sector. The rally was even more pronounced in New York, where the company’s American Depositary Receipts surged 14 percent on Nasdaq, clawing back a chunk of the 10 percent decline they had suffered over the prior month.
Micron’s fiscal third-quarter results for 2026 were nothing short of staggering: revenue hit $41.46 billion, a 346 percent year-on-year explosion, with GAAP gross margins of 85 percent and earnings per share of $25.11. The guidance for the fourth quarter was equally punchy, with a revenue forecast of $50 billion, give or take a billion. For investors who had watched memory stocks get pummeled in recent weeks, the message was clear: pricing power in the chip industry remains firmly intact.
The broader market took note. The Roundhill Memory ETF, which counts Samsung, SK Hynix and Micron as its top holdings, jumped 11 percent after having cratered 31 percent in the preceding month. South Korea’s Kospi index, which had suffered three straight losing sessions, rebounded above the 6,700-point mark as foreign bargain hunters waded back in. Samsung Electronics rose 6 percent on the day, while SK Hynix added 4 percent.
A Technical Correction, Not a Fundamental Reversal
Analysts have been quick to frame the recent selloff as a mechanical phenomenon rather than a deterioration in business conditions. The 37.10 percent plunge over the prior 30 days was attributed to forced liquidations of leveraged ETFs and profit-taking after a blistering run, not to any softening in demand for memory chips. JPMorgan is standing by its 12-month Kospi target of 12,500 points, while NH Investment & Securities sees a solid floor at 6,000 points.
Should investors sell immediately? Or is it worth buying SK Hynix?
That interpretation matters because it suggests the underlying investment case for SK Hynix remains intact. The company sits at the center of three powerful trends: a dominant position in high-bandwidth memory chips for Nvidia’s AI accelerators, a structural supply shortage across the industry, and multi-year supply agreements with hyperscaler clients. Together with Samsung and Micron, SK Hynix forms an oligopoly that has turned the AI infrastructure buildout into record margins.
Yet the stock is still trading 38.5 percent below its 52-week high of 2,987,000 won, reached on June 25. That gap underscores just how violent the correction has been, even as the year-to-date return remains a stunning 182.6 percent. The annualized 30-day volatility stands at 117.41 percent, an extraordinary figure even by growth-sector standards, and the relative strength index of 41.2 suggests a market still searching for direction.
The Bull Case vs. The Chairman’s Warning
The rally narrative rests on a documented physical shortage of both HBM and conventional DRAM that analysts expect to intensify through 2027. SK Hynix has secured supply commitments with Nvidia reportedly extending to 2030, and the company is pouring capital into expansion: a new fab in the Yongin semiconductor cluster, the Cheongju P&T7 advanced packaging facility, and procurement of ASML’s EUV lithography tools. All of this is being funded in part by the historic Nasdaq listing of its ADRs on July 10.
But the bear case has a powerful voice behind it. SK Group Chairman Chey Tae-won himself described current memory prices as “abnormal,” a comment that fanned fears of an approaching cyclical peak. Citigroup has downgraded South Korean equities, citing the risk of capital rotation toward cheaper Chinese AI names. The stock’s technical position is fragile: even after Tuesday’s bounce, it remains 16.4 percent below its 50-day moving average of 2,196,213.72 won.
External headwinds add to the uncertainty. Rising energy costs and geopolitical tensions in the Middle East could squeeze manufacturing margins, while long construction timelines mean that even fully funded capacity expansions won’t ease supply constraints in the near term. That tightness may support prices for now, but it also caps growth potential.

The Binary Moment Arrives July 29
All of this sets the stage for what analysts describe as a binary test for the stock. On July 29 at 9 a.m. Seoul time, SK Hynix will hold its second-quarter earnings conference call — one of 402 companies reporting that day. The market will be listening for two things above all: commentary on HBM4 delivery timelines and any signals on pricing trends.
If management strikes a similarly bullish tone to Micron’s June call, it could calm the volatility that has rattled the stock in recent weeks. CEO Kwak Noh-jung has previously warned of a severe memory shortage in the years ahead, and investors will want to know whether that view has hardened or softened. Confirmation of stable HBM yields and continued growth in DRAM export prices would give the stock a solid foundation above its 100-day moving average of 1,626,321.06 won.
The alternative scenario is less forgiving. Signs of declining capital efficiency, cooling demand from smartphones and PCs, or any hint that the chairman’s “abnormal” comment reflects a genuine inflection point could send the stock testing the support levels established during the recent rout. Either way, the next few days are unlikely to be quiet. With volatility at 117 percent and positioning still uncertain, investors are already placing their bets ahead of the earnings reckoning.
