Robert Shiller on SK Hynix
SK Hynix has a dated HBM lead, but its price and coverage risk turning that lead into a permanent-cycle story before the record can prove it.
SK Hynix supplies a real precipitating factor for Shiller’s process: a dated qualification and production lead. The dossier dates Samsung’s failed Nvidia tests to May 2024, SK Hynix’s volume production to September 2024, and Nvidia’s allocation of most of its 2026 HBM4 demand to SK Hynix before Samsung completed qualification. The dossier also records the new-era test: Nasdaq coverage framed SK Hynix as a bet that AI would end memory’s boom-and-bust cycle. Management strengthened that claim by forecasting demand above supply past 2030, after warning about a shortage emerging in 2027. The dossier therefore presents both a genuine operating advantage and a claim of permanent structural change.
The provider-current Seoul series shows the feedback material. SK Hynix closed September 18 at KRW 1,857,000, up 6.42%, or KRW 112,000, from the prior close of KRW 1,745,000. The same series records an earlier fall of 54.7%, or KRW 1,597,000, to KRW 1,322,000 from KRW 2,919,000 between June 22 and July 30. TEXXR’s snapshot labels 2026 Q3 its latest complete period and logs 52 SK Hynix articles, compared with an average of 10.6 articles per quarter across the preceding eight quarters. TEXXR’s count measures coverage attention, not demand, shortages, or buyer recruitment.
Reuters sources described Intel talks that could face Seoul opposition and a Solidigm factory review, so Reuters did not establish executed projects. Reuters sources also described CXMT’s NAND plan, while a document supported SK Hynix’s power proposal rejection because of uncertainty over long-term chip demand. Reuters therefore supplies skeptical controls against the permanent-shortage story.
The record cannot establish Shiller’s “naturally occurring Ponzi process,” which requires rising prices, contagious explanations, recruited buyers, and another price rise; the materials show a price move and more attention, but no recruited-buyer evidence. The supplied materials also lack the decade of real earnings or cyclically adjusted multiple required for Shiller’s historical valuation test. SK Hynix therefore leaves a split Shiller record: the operating lead is dated, while the permanent cycle break and complete feedback loop remain unproved.
