SK Hynix’s $29 Billion Confidence Bet Faces Its November Reckoning

The arithmetic of SK Hynix’s current position is almost contradictory. The stock jumped 3.3 percent on Friday to close at 1,649,000 won in Seoul, yet it still sits 45 percent below the record high it set in June. It has climbed 154 percent since the start of the year, but trades 11 percent beneath its 50-day moving average. Those numbers capture a company whose operational story has rarely looked stronger — and whose share price remains stubbornly unconvinced.

That hesitation has a name: Solidigm. The US subsidiary has been a lingering overhang since early August, when the Korea Economic Daily reported that SK Hynix was weighing a roughly 5 trillion won capital raise ahead of a possible initial public offering. The company pushed back in a filing with US regulators, insisting the report did not reflect any approved plan. Management said it was exploring options to strengthen Solidigm’s competitiveness but had settled on no concrete course of action. A self-imposed deadline to update the market by September 4 has come and gone, leaving investors none the wiser about the unit’s fate.

A Buyback With an Expiration Date

What has been unambiguous is the scale of SK Hynix’s share repurchase program. Launched on August 20, the 40 trillion won buyback — paired with a full cancellation of the acquired shares — had already worked through 32.4 percent of its volume by September 3. Analysts expect completion by mid-October. The message from management is clear enough: it considers its own equity undervalued.

But the program is finite, and its conclusion in November will remove a meaningful source of demand. Technical levels in the analysts’ cited notation look less reassuring than the headline numbers suggest, with support pegged at 165 and resistance at 185 to 190. The 30-day volatility reading of 129 percent and an RSI of 48.3 point to a market that has yet to settle on a near-term direction.

Washington, Indiana and the Politics of Chip Supply

The buyback is only half the story. SK Hynix is simultaneously pouring capital into new production capacity — expanding its Dalian facility by roughly 50 percent while exploring a possible joint venture in Japan. The strategic logic extends beyond customer demand. US Commerce Secretary Howard Lutnick has made clear that companies without US manufacturing operations face tariffs, and the late-September trip planned by SK Group chief Tae-won Chey and Samsung chief Jay Y. Lee to meet Nvidia CEO Jensen Huang in New York reads as a direct response to that pressure.

The company’s American footprint is already taking shape. On August 27, SK Hynix broke ground on an advanced chip-packaging facility in West Lafayette, Indiana — its first US production base for high-bandwidth memory. The investment exceeds $4 billion, with the cleanroom building on the Purdue Research Park campus slated for completion by October 2028. Series production of the next-generation HBM4E memory is targeted for the third quarter of 2029. A parallel agreement with Purdue University covers joint research into packaging technologies and recruiting engineers from the Midwest.

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

The timing reflects competitive reality. Counterpoint Research data shows SK Hynix held a 58 percent share of global HBM revenue in the first quarter of 2026. A domestic US site helps secure that position with customers increasingly demanding local supply chains — even as Samsung narrows the gap in the broader HBM segment, having grown its share from 21 to 33 percent in the second quarter.

The Squeeze That Isn’t Marketing

SK Hynix’s core argument rests on a genuine supply shortage. The company maintains a 50 percent share of the HBM segment, and the pricing data supports the case that demand is outstripping what manufacturers can produce. Spot prices for HBM3E memory have reached roughly $2,100, while contract prices sit at just $365 to $510. That gap is the clearest evidence that the much-cited “DRAM shortage” reflects a real supply deficit rather than industry spin.

There are also domestic costs to the expansion drive. SK Hynix has agreed to prepay 5 trillion won to state utility KEPCO for electricity covering 2027 through 2031 — a figure that underscores both how seriously the company takes power supply for its planned capacity growth and how strained South Korea’s state infrastructure has become. KEPCO carries liabilities exceeding 210 trillion won.

Analysts Hold the Line

Wall Street has not wavered. Citi reaffirmed its buy recommendation on September 2, and Bernstein followed on Friday with its own buy rating. Both houses cite persistently robust demand for memory chips powering AI servers — a picture reinforced by recent outlooks from Nvidia and Broadcom, which describe AI demand as supply-constrained but durable over the long term.

The weekly numbers tell a more cautious tale: a 0.2 percent decline over five sessions and a 1.1 percent drop on the month. For all the operational momentum — a record quarter over the summer, a multibillion-dollar US investment, sustained analyst support — the share price remains hostage to the unresolved Solidigm question and broader sector volatility.

The real test arrives in November. When the artificial demand impulse from the buyback disappears, SK Hynix will have to prove that its operating strength alone can carry the stock. The 11 percent discount to the 50-day average may yet look like a pause rather than a problem — but the market is clearly withholding judgment until the support mechanism runs its course.
