Latest \u2014 Computex 2026, Taipei (Jun 2)
• Chey Tae-won pledged to DOUBLE SK Hynix wafer capacity over 5 years \u2014 a reversal from March, when he said new capacity "couldn't be added on demand." Cited memory shortage persisting through 2030. Exec-credibility read: a chairman reversing capacity guidance in 90 days is a high-conviction demand signal, not a hedge.
• Jensen wrote "Please Make More" on an HBM4E wafer and "Love SOCAMM" on a 192GB SOCAMM2 module at the booth \u2014 3rd Chey-Jensen meeting in 7 months. The top buyer publicly asking the top supplier to accelerate.
• Vera Rubin now in full-scale mass production (MSFT+Foxconn bring-up done); SK Hynix holds ~58-70% of Rubin HBM4 orders.
• Flow: Janus Henderson (Richard Clode, Global Technology Leaders Fund) plans to add SK Hynix, citing outsized earnings growth as multi-year supply contracts reprice higher in 2027. Korean media now floating ₩4M targets (~$2,960, +72%).
• Market cap surpassed $1T; YTD +260%+. Competitive watch (SemiAnalysis): Samsung Foundry producing HBM4 base/logic dies on SF4 \u2014 qualification is the item to track.

Market Context \u2014 June 5 Selloff (KOSPI circuit breaker)
SK Hynix fell ~9% (Samsung -6-7%, KOSPI -6% intraday). Read: crowded-position reset, not a thesis break \u2014 but with one genuine fundamental watch-item.
Triggers:
• Broadcom guide: Q3 AI rev $16B vs $17.2B expected, FY $56B vs $57.6B; $100B FY2027 target not raised. Still +200% YoY \u2014 an expectations miss, not a demand collapse.
• Rubin memory rumor (the one that matters): reports NVIDIA may cut Rubin NVL72 SOCAMM from 55TB \u2192 28TB/rack \u2014 hit memory names directly (Micron -9.5%, SanDisk -11%). SK Hynix is the exclusive 192GB SOCAMM2 supplier, so this is the real watch-item. Caveats: unconfirmed rumor; SOCAMM is not HBM4 (the bigger value driver); 28TB still large; a 20-30% HBM4 shipment shift on Rubin timing was already known.
• Crowded unwind: foreign net selling, leveraged single-stock ETFs -20%, Korean FinMin flagging retail leverage.
What's UNCHANGED (the disconnect): 2026 revenue consensus RAISED ₩266T \u2192 ₩318T and EPS ₩218K \u2192 ₩281K as the stock fell; MSFT/Meta/Google booked most 2026 HBM capacity; US-listing feedback "tremendously positive." Forward P/E now ~7x (vs ~23x Korean semi avg).
Honest read: fundamentals improved while price dropped \u2014 classic crowded-trade reset. But the stock was ~25% above the (raised) ₩2.08M consensus at the peak, and the SOCAMM rumor (if confirmed) is a real per-system content headwind \u2014 so some reset was rational, not pure irrationality. Watch: SOCAMM confirmation, foreign-flow reversal, Samsung HBM4 (unveiled Jun 1).
Base / Bull Price Targets (% from \u2248₩2.15M)
End 2026
Base₩1.9M ($1,407) -12%

End 2028

Bull₩5.0M ($3,704) +133%
Scenario ladder from the thesis model. Goldman-implied 2028 FV ~₩5.1M sits between our Base and Bull. 2026 base predates the rally \u2014 under review.

🧠 Governing Dynamic: The AI platform transition generates its own demand. More AI → more tokens → more compute → more memory → more optics. This self-reinforcing cycle is bounded only by physical manufacturing capacity (ASML machines, TSMC packaging, fab space) — which is constrained through 2030.
SI-CTRL analysis: This is not a product cycle. It is a platform transition. Revenue models based on gradual growth curves understate the Rubin step-function.
