The market often frames AI hardware as a sequence: GPU first, then memory, then substrates. That is only partly right. AI infrastructure is now a rack-scale system made of GPUs, CPUs, DPUs, NICs, switch ASICs, memory modules, power boards and low-loss CCL. Every chip expansion needs a board. This sector thesis connects Samsung Electro-Mechanics, Daeduck Electronics, Doosan Electronic BG, Kolon Industries and Pamicell to the same system-level bottleneck.

Part 5 was the conservative endpoint of new-coordinate definition (company defining, market discounting). Part 6 was the aggressive endpoint (market pricing, company catching up). Part 7's Viva Republica (Toss) goes one step further — a pre-listing case where the coordinate itself hasn't been accounting-closed yet. This piece refuses to declare a single 'base case'. Considering the five institutional walls of US listing — public F-1 not yet filed, ADR/FPI discount, Korean financial-regulation exposure, secondary-share liquidity complexity, and the standard 30–40% IPO discount — the possible price spectrum spans $5B to $15B. Reuters' '$10B+' headline sits at one point in the upper-end region, reachable only when all five walls are cleared and the super-app narrative is convinced. Inverting the four scenarios into the series' implied-cost-of-equity matrix reveals that the same company can land anywhere from one endpoint to the other.
Part 5's Korea Investment Holdings was 'a company defining a new coordinate while the market applies a conservative discount.' Part 6's KakaoBank is precisely its mirror image — a company actively claiming a new coordinate ('mobile financial platform + AI-native bank + ROE 15%'), with the market already pricing that claim in. Implied cost of equity ~4.2% — far below all five other companies in the series and the polar opposite end of Korea Investment Holdings's 17.3%. Two ends of the same 'new coordinate definition' chapter. The company pulling the market vs. the market pulling the company. The accounting meaning of the asymmetry.
Series Parts 1–3 framed Meritz, Kiwoom, and KB as three peaks. Part 4 traced Shinhan's transit toward KB's coordinate. Part 5's Korea Investment Holdings (071050) maps onto none of them cleanly. Equity ₩12.1T → outstanding short-term notes (발행어음) ₩21.5T against a ₩24.2T cap (89% utilization) → IMA balance ₩1.9T → combined funding capacity ₩36.3T. That 5-step 'fund → asset-create → operate' flywheel exists nowhere else in the series. ROE 18.5% × PBR 1.07× = implied cost of equity 17.3% — the highest of all five. The 5.8 pp gap is not a 'mispricing' — it is the accounting evidence that 'a new coordinate is being defined'. The speed at which it gets recognized depends on two self-stabilizing mechanisms: governance and shareholder-return policy.
