Summary
Investing.com reports that Samsung and SK Hynix shares surged on April 1, 2026, rebounding from over 20% losses suffered during March 2026. The March losses were driven by concerns over AI memory demand after Google’s TurboQuant algorithm claimed to slash AI memory requirements, combined with OpenAI spending cuts and the Sora shutdown. The rebound was driven by bargain buying across the broader Korean tech sector.
Key Points
- Samsung jumped over 10% to 184,300 won on April 1, 2026
- SK Hynix rallied as much as 9.5% to 884,000 won on the same day
- Both were among the biggest boosts to the KOSPI index, which rallied 6.5% after losing over 19% in March
- The March losses (over 20% for both stocks) were driven by concerns over long-term memory chip demand after Google’s TurboQuant algorithm
- Additional downward pressure came from speculation over memory chip price falls due to OpenAI spending cuts and Sora shutdown
- Confirms OpenAI signed agreement with Samsung and SK Hynix for 900,000 DRAM wafers — described as “a major chunk of supply”
Newsletter Angles
- The Jevons timeline: TurboQuant published March 24 → memory stocks crash 20%+ through March → rebound April 1. The market took roughly one week to process the Jevons logic (efficiency won’t reduce demand, it’ll expand addressable market). This is the live-case timeline for the Concept Decoder piece.
- Bargain buying, not fundamentals: The rebound is described as “bargain buyers stepped in” — not a fundamental reassessment. The Jevons reasoning (efficiency increases total demand) came from analyst commentary during the recovery, not from the rebound itself. The piece should be precise about this distinction.
Entities Mentioned
- Samsung — surged 10% on April 1 after 20%+ March losses
- SK Hynix — rallied 9.5% on same day, same pattern
- Google — TurboQuant algorithm cited as primary cause of March selloff
- OpenAI — spending cuts and Sora shutdown contributed to downward pressure
- KOSPI — Korean index rallied 6.5% after losing 19% in March
Concepts Mentioned
- Jevons Paradox — the March-to-April timeline is a real-time demonstration: panic (efficiency = less demand) followed by reversal (efficiency = more demand via expanded use cases)
- AI DRAM Crisis — the rebound occurs within the broader crisis; prices remain elevated despite the recovery

Notes
- This is a brief market-reaction piece from Investing.com, not deep analysis. Its primary value is the precise timeline: March losses (20%+) → April 1 rebound (10% / 9.5%). This fills a specific source gap in the wiki — the TurboQuant crash was documented, but the recovery date and magnitude were not.
- The piece attributes the March losses to Google’s algorithm and OpenAI’s spending cuts but does not name TurboQuant specifically — it describes “a new algorithm which it claimed could slash AI’s memory requirements.” Cross-reference with How Sam Altman’s OpenAI may have caused the worst consumer hardware crisis for the TurboQuant name.
- The “bargain buying” framing suggests the April 1 rebound was technical (oversold bounce) rather than fundamental. The Jevons-based analyst reasoning that efficiency would increase total demand came separately from the price action.
