SK Hynix’s Split Personality: Record Earnings, a Thin-Tape Glitch, and the $263 Billion Question

The arithmetic of SK Hynix’s current predicament is almost absurd on its face. The South Korean memory-chip giant just posted a record quarterly net profit of 93.9 trillion won, its operating income surged 557 percent year over year, and its combined cash pile with Samsung Electronics is projected to hit 375 trillion won — roughly $263 billion, more than double Nvidia’s net cash position. Yet the stock has spent the past fortnight lurching violently lower, leaving shareholders to reconcile the strongest fundamentals in the company’s history with the ugliest tape in recent memory.

The latest leg of the selloff came on Thursday, when shares closed at 1,495,000 won after sliding 10.37 percent. The damage extended into Friday, with the stock shedding another 5.35 percent to trade at 1,415,000 won. That followed an earnings report on July 29 that, by any conventional measure, should have been a celebration: revenue of 79.3 trillion won, operating profit of 60.5 trillion won at a 76 percent operating margin, and a net figure that dwarfed even the most bullish forecasts. The problem was the gap between those numbers and what the street had penciled in. LSEG SmartEstimates had analysts looking for roughly 64 trillion won in operating profit and 84 trillion won in revenue — and the miss triggered a 9.6 percent one-day drop on the report itself.

A Thin-Tape Episode That Rattled Nerves

If the earnings reaction was mechanical, what happened Thursday morning was something else entirely. In pre-market trading, SK Hynix plunged nearly 30 percent to 1.168 million won — on just eleven shares changing hands, according to the Seoul Economic Daily. The episode, which unfolded against a market capitalization still above 1,100 trillion won, belongs to a recent pattern of outsized moves in Korean equities driven by vanishingly small liquidity. The trading platform Nextrade plans to introduce a circuit-breaker mechanism on September 14 to curb such extreme volatility. For all the drama, the stock still sits 17.09 percent above its 200-day moving average, a sign that the longer-term uptrend has bent but not yet broken — even as the 50-day average of 2,140,092.50 won leaves the current price roughly 30 percent below that nearer-term benchmark.

The Samsung Factor Shifts the Rotation

Part of the pressure is competitive. Samsung Electronics unveiled the world’s first samples of its 12-layer HBM4E memory chips, a development that gave its own shares a visible lift in Seoul and encouraged investors to rotate some capital toward the cheaper, more diversified rival. SK Hynix still dominates the high-bandwidth memory market with a 58 percent share in the first quarter, according to Counterpoint, ahead of Samsung and Micron. BNP Paribas pegs the total HBM market at $76 billion for 2025, expanding to $156 billion by 2027. But the narrative has shifted from unchallenged leadership to a two-horse race, and the valuation gap is conspicuous: SK Hynix trades at roughly half of Micron’s multiple despite its HBM supremacy.

Wall Street Sends a Different Signal

Across the Pacific, the picture could hardly be more divergent. The New York-listed ADR under the ticker SKHY climbed 8.2 percent on Wednesday to $154.38 after Wedbush analysts upgraded the stock to “Strong Buy,” citing quarterly earnings per share of $8.76 against a consensus of $5.12 — even though revenue of $52.83 billion trailed the expected $59.05 billion. The average analyst price target stands at $245.50. The post-earnings coverage wave has been striking: Cantor Fitzgerald initiated with Overweight and a $300 target, while Rosenblatt, Bank of America, UBS, Needham, Stifel, Wolfe Research, and RBC Capital Markets all launched coverage with buy ratings and targets ranging from $200 to $320. Barclays’ Simon Coles trimmed his target from $330 to $300 on July 29, citing softer expected average selling prices, but kept his Overweight stance. A notable insider signal: SK Group chairman Chey Tae-won purchased 4.8 billion won worth of shares on July 31.

The ADR enthusiasm partly reflects a structural story. A planned Nasdaq listing of Solidigm, SK Hynix’s US-based NAND subsidiary, could eventually close the valuation discount, according to TrendForce — though debt and aging production equipment at Solidigm temper expectations of a near-term IPO.

Should investors sell immediately? Or is it worth buying SK Hynix?

The Capital Returns Question Hangs Over Everything

The most consequential debate, however, is about what SK Hynix does with its money. The company completed a 25-day lock-up period required under US securities law following its ADR placement, which expired on August 4. Management said on July 29 it could not provide details on shareholder return plans until that process concluded. Investors are now pressing hard for payouts, with reports suggesting SK Hynix is considering raising its payout ratio to at least 80 percent of free cash flow. Of the combined 375 trillion won in net cash projected for SK Hynix and Samsung, SK Hynix alone accounts for 141 trillion won.

That demand has run into political resistance. Industry Minister Kim Jung-kwan warned that more generous distributions could set South Korea back in the global race, pointing to China’s state-backed competitor CXMT and its aggressive investment push. He has also called for reform of the statutory 52-hour work week to protect the domestic industry’s competitiveness.

What’s Next: HBM4 Ramp and New Memory Frontiers

Operationally, the pipeline remains full. SK Hynix guided for DRAM shipments to rise roughly 10 percent quarter over quarter in Q3, with NAND bit shipments growing in the low single digits. Capital expenditure for the year is set to exceed 40 trillion won, and the first clean-room phase of the Yongin fab is slated to begin operations in early 2027. HBM4 mass production started in the second quarter, with the full ramp expected in the second half of this year; samples of the HBM4E successor have already shipped, with volume production targeted for 2027.

At the Flash Memory Summit in Santa Clara, SK Hynix and SanDisk unveiled initial specifications for High Bandwidth Flash, a new memory technology supporting capacities up to 512 gigabytes. Google and Tenstorrent have signaled interest in joining the associated industry standard; Nvidia has not, and commercialization is not expected before 2027. The company also showcased its tenth-generation 4D NAND wafer with 375 layers, promising a 2.5-fold improvement in performance per watt over the prior generation.

For now, the market’s verdict on SK Hynix depends on which screen you are watching. In Seoul, the tape says caution. In New York, the analysts say buy. The truth, as ever, lies somewhere between a record earnings report and a stock that has yet to find its footing.
