Core Position
Largest shareholder of SK Hynix — capturing the AI semiconductor supercycle through NAV discount compression
Investment Thesis
SK Square is a pure holding company with SK Hynix (20.1% stake) as its core asset. With 97.7% of NAV concentrated in a single asset, it is effectively a structure to "buy SK Hynix at a discount." After surging 1,367% from a 52-week low of ₩91,000 (Jul–Aug 2025) to an all-time high of ₩1,337,000 on May 27, 2026, the stock has corrected to approximately ₩1,020,000. The current NAV discount of ~47% still shows a 17pp gap to the 2028 target of 30%, and closing this gap is the primary price driver. With a Gangbangcheon B grade and Geochajesi 12/20, near-term further correction risk is elevated — but on a medium-to-long-term view, staged entry after confirming support at the Fibonacci 61.8% level (₩987,000) or the ₩800,000 zone is a viable strategy.
① Non-Financial — Holding Company Regulation Paradoxically Creates Structural Moat
SK Square's moat is not technology or brand — it is regulation. The mandatory 20%+ SK Hynix ownership requirement under Korea's Holding Company Act creates a structural sell-defense, while positioning the stock for foreign institutional investors as a "proxy investment to bypass SK Hynix concentration limits." NAV at 97.7% concentrated in a single asset is a structural vulnerability from a portfolio diversification standpoint, but simultaneously a leveraged position in the world's leading HBM producer — a paradoxical strength. Shareholder return track record (3 consecutive years of buyback-and-cancel, ₩200B cash dividend plan for 2026) underpins management credibility. → Full moat ratings, management transition (Park Jeong-ho → Kim Jae-gyu), governance, and risk analysis in the Non-Financial tab.
② Validator — Gangbangcheon B × Geochajesi 12/20 = Wait for Support Confirmation
Open-form framework. 4 of 5 Gangbangcheon steps passed (steps 1–4 ✅, NAV discount model step 5 ⚠️). Step 1: AI datacenter HBM demand growing 30%+ annually ✅. Step 2: SK Hynix 50%+ HBM market share, global #1 ✅. Step 3: Holding company structure (dividends, equity method income, exits) ✅. Step 4: Q1 2026 op income ₩8.3T (+400% YoY), ROE 55.1% ✅. Step 5 (NAV discount): conservative scenario upside only +3–24% — thin margin. Post-3x YTD run weakens case for new entry. Geochajesi 12/20 — Volume 3 + Chart 3 + Catalyst 4 + Market 2. Near-term RSI overbought + continued large foreign selling weakens entry signal. → Full NAV discount scenarios and Geochajesi item scores in the Validator tab.
③ Technical — -24% Correction from ATH, Testing Fibonacci 50% Zone
From the ATH of ₩1,337,000 on May 27, the stock fell -24% in just two days to ~₩1,020,000. Fibonacci retracement basis: Apr 24 low ₩770,000 → May 27 high ₩1,337,000; the 50% retracement at ₩1,054,000 is near the current zone. Short-term (5-day MA) broken to downside ↓; medium-term (60-day ~₩750,000) and long-term (120-day ~₩620,000) MAs remain below with bullish alignment intact. Classic short-term overheating resolution with 5d/20d MA breakdown in progress. Key support: ①₩987,000 (Fib 61.8% + ₩1M psychological) ②₩800,000 (April supply zone, projected 20d MA convergence). Break below ₩1,000,000 psychological opens path to ₩800,000. → Full 3 scenarios, chart, RSI, and bull/bear signals in the Technical tab.

Bull Case
- SK Hynix HBM market leader (50%+) — structural demand from continued AI datacenter investment
- NAV discount 47%→30%: 17pp compression headroom — +30–58% upside if 2028 target achieved
- ₩310B+ confirmed shareholder returns 2026–2028 — buyback, cancellation, and cash dividend combined
- SK Hynix consensus upgrade to ₩165T — direct A-grade catalyst linkage to parent
- Institutional proxy structure — structural fund inflow from institutions constrained on direct SK Hynix exposure
Bear Case
- Already substantially re-rated — 3x YTD, 10x+ vs one year ago. Residual upside for new entry sharply reduced
- Foreign investors in sustained large-scale selling since mid-May — near-term supply overhang risk
- NAV 97.7% in SK Hynix single asset — SK Hynix -20% would reduce NAV by ~₩37T
- NAV discount could re-widen to 50%+ — structural discount re-pricing possible after institutional rebalancing completes
- Restructuring delays in ICT non-core subsidiaries (11st, System AI, etc.) — ongoing small-scale NAV erosion
