The arithmetic at SK Hynix is getting harder to reconcile. The memory chip maker just posted the best quarterly profit in its history, yet its shares have shed nearly a third of their value in a month. Investors are no longer asking whether the company can make money — they want to know what it plans to do with it.
That question came into sharp focus on Friday, when the Seoul-listed stock closed at 1,422,000 won, down 4.88 percent on the day. The weekly loss stands at 17.23 percent, and the monthly decline has reached 31.50 percent. Even after that brutal correction, the shares remain up 118.87 percent since the start of the year — a reminder of just how far the rally had run before the air came out.
A Record Quarter That Failed to Impress
The trouble traces back to July 29, when SK Hynix reported second-quarter revenue of 79.3187 trillion won and net profit of 93.9226 trillion won — both all-time highs. But the headline numbers flattered the underlying performance. Net income was inflated by a one-off gain of 63.3 trillion won from the sale of the company’s stake in Kioxia, while operating profit of 60.5426 trillion won came in well short of the 64 trillion won analysts had penciled in. Revenue also missed the consensus estimate of 84 trillion won.
The market’s response was swift and unforgiving: the stock dropped 9.6 percent. Management pointed to lower-than-planned HBM4 shipments, saying mass production had begun in the second quarter but that the full ramp-up would only come in the second half of the year.
A Friday Full of Decisions
Friday brought a flurry of announcements that left investors parsing signals in different directions. The company declared a dividend of 375 won per share and said it was actively reviewing additional capital return measures, with details to be finalized in the third quarter. Local media have speculated about a program worth around 100 trillion won, including a share buyback component of up to 40 trillion won.
At the same time, the board approved investments totaling roughly 54.3 trillion won for two new fabrication plants: 35.2 trillion won for the “Y2” DRAM fab in the Yongin cluster and 19.1 trillion won for the “M17” NAND fab in Cheongju. The juxtaposition was hard to miss — a company promising to return capital while committing enormous sums to capacity expansion. Investors appeared to read the investment figure as the louder signal.
Adding to the uncertainty, Bloomberg reported that SK Hynix is exploring a possible sale of its packaging plant in Chongqing, China, a deal that could value the facility at around $3 billion. The company said talks remain at an early stage and declined to comment officially.
A Week of Wild Swings
The Friday decline capped a particularly turbulent stretch. On Wednesday, the stock had jumped as much as 7.9 percent in Seoul, outpacing rival Samsung Electronics’ 6 percent gain, on speculation that the 25-day quiet period following the July 10 ADR listing had ended on August 4, clearing the way for capital return announcements. The next day brought a brief flash crash on the Nextrade alternative trading platform, where eleven shares changed hands after the price collapsed to the 30 percent daily limit before the 50-minute pre-market session ended down about 2 percent.
Should investors sell immediately? Or is it worth buying SK Hynix?
The Bull Case: Cash, Contracts, and Conviction
For those inclined to buy the dip, the supporting evidence is substantial. Chairman Chey Tae-won purchased SK Hynix shares worth around 4.8 billion won on July 30 — his first direct acquisition of the stock — a move widely interpreted as a vote of confidence. The balance sheet is solid: liquid assets have climbed to 88 trillion won, and the debt ratio sits at a modest 7 percent. Long-term supply agreements with roughly ten key customers provide revenue visibility that most semiconductor companies can only dream of.
US analysts have been notably bullish on the American Depositary Receipts, which began trading on the Nasdaq on July 10 and raised approximately $26.5 billion — the largest capital raise by a foreign company on US exchanges. Cantor Fitzgerald set a price target of $300 on Tuesday, more than double the ADR’s closing price of $142.72 on Monday. Rosenblatt initiated coverage the same day with a “Buy” rating and a $320 target, the highest among all covering banks, calling SK Hynix a “technology leader at a discount price.” Bank of America, Stifel, and RBC Capital Markets set targets of $250, $240, and $200 respectively, while Wolfe Research and Needham both launched coverage with positive ratings.
The underlying growth story remains intact. Second-quarter revenue rose 257 percent year over year to 79.3 trillion won, operating profit surged 557 percent to 60.5 trillion won, and the operating margin hit a record 76 percent. The company has started mass production of HBM4, with volume ramp-up scheduled for the second half, and has already delivered initial samples of the HBM4E successor generation. The broader SK Group partnership with Nvidia, valued at more than $500 billion, includes a long-term supply agreement for AI memory. At the FMS 2026 conference in Santa Clara, SK Hynix and Sandisk jointly presented the first standard specifications for High Bandwidth Flash, a new memory technology also backed by Google and Tenstorrent, while SK Hynix publicly showed its tenth-generation NAND with 375 layers for the first time.
The Bear Case: Expectations Set a Brutal Bar
The risks are equally visible. The Q2 reaction demonstrated that SK Hynix is now judged against extraordinarily high expectations — and that missing them carries severe penalties even when profits are record-breaking. The stock trades roughly 33.04 percent below its 50-day moving average, and the annualized 30-day volatility of 145.71 percent speaks to how frayed investor nerves have become.
External pressures are mounting too. Chinese competitor CXMT is intensifying competition in the DRAM market, speculation persists about Chinese suppliers potentially entering Apple’s supply chain, and Nvidia share sales have cast a shadow over the entire AI infrastructure complex. The 54.3 trillion won in planned factory investments will tie up substantial capital, while the fate of the Chongqing plant sale remains entirely uncertain.
The Defining Question
Everything now hinges on whether SK Hynix delivers concrete, quantified details on its capital return program by the end of the third quarter — or whether investors are left with vague promises. Many local observers expect specific measures to accompany the autumn earnings release at the latest.
If the company can pair a credible buyback program with a genuine HBM4 production ramp-up in the second half, the stock has room to stabilize from what look like oversold levels. If the details slip into October, or if the HBM4 ramp disappoints again, the downward pressure could persist. The next milestone is the third-quarter announcement on capital returns — with the full quarterly results in the fall serving as the ultimate test of whether SK Hynix can turn its record profits into a story investors are willing to pay for.
