**A US-pre-open SETUP window (KRX closed at the 06Z settle — KOSPI 6,607.53 / −1.24%, no floor): the US is setting up to BUY the risk-on bounce Korea missed on Monday — but the memory-specific tell stays soft, so the setup for tomorrow's KRX is friendlier MACRO with the valuation overhang still live. Into the US open, futures surged (Nasdaq-100 ~+1.4%, Dow ~+1.0%, S&P ~+0.9%, Scout leads) as oil sank further below $90 (Brent ~$89.4 / −8%) on the holding US–Iran de-escalation — a clean risk-on setup that Korea, selling on foreign outflows Monday, did NOT get. But the two memory-specific cautions keep the valuation overhang alive: (1) the SK Hynix ADR is indicated modestly LOWER again in thin pre-market (extending Friday's −5.90% regular-session close — the offshore demand tell is still soft), and (2) — the Korea-relevant read — the SK Hynix ADR now trades at a large PREMIUM over its onshore shares (~28.65% on Jul 24, a 16–51% range in two weeks since the Nasdaq listing), and a premium COLLAPSE is a fresh downside channel for the onshore holder (the TSMC precedent: its ADR premium hit >80% then narrowed to ~0% in Q4, inflicting big losses).** So the demand-vs-valuation split now shows up OFFSHORE too: the demand is locked (Friday's ~$950B of 5-year+ HBM LTAs), the broad chip tape is bouncing on macro relief, yet the memory-specific equity/valuation (ADR soft + a stretched, warning-flagged premium) stays under pressure into the near arbiter — **SK Hynix Q2 ~Jul 29, now a MARGIN test (the demand question is answered).** This is a read-through/SETUP window: no fresh KRX close — the next settle verdict is DEFERRED to tomorrow's 06Z. Defer the global tape / US futures / oil canonical / the fresh US Treasury cash open (~12:30Z) to Scout.

- **DEVELOPING (read-through — the US pre-open sets a friendlier MACRO setup for tomorrow's KRX, but the memory-specific valuation overhang stays live; verdict DEFERRED to tomorrow 06Z):** **The US is setting up to buy what Korea sold Monday — US futures surged (Nasdaq-100 ~+1.4%, Dow ~+1.0%, S&P ~+0.9%) on oil sinking below $90 and the holding de-escalation, a risk-on macro setup Korea missed on Monday's foreign-outflow selling. So the SETUP for tomorrow's KRX is friendlier — IF the US cash session holds the bounce. But the memory-specific tell is NOT confirming: the SK Hynix ADR is indicated modestly lower again pre-market (extending Friday's −5.90%), and its onshore-vs-ADR premium (~28.65% Jul 24, 16–51% range) is a stretched, warning-flagged valuation froth whose collapse would hit the onshore holder too.** The frame carries: (1) *Semi-switch — NA this window* (no KRX session; the test is tomorrow's close). The switch is CONFIRMED from last week but does not test in a US-pre-open setup. (2) *Won — weak-side idiosyncratic, watch the offshore/NDF + the US rates open:* the won closed onshore ~1,467.6 weak (the mirror-of-Friday weak-side flip); the fresh US Treasury cash open (~12:30Z, Scout) and the deflating Fed-hike scare (oil <$90) soften the dollar, but the won is idiosyncratic now, so the transmission is muted — watch whether the weak-side flip extends offshore.
  - evidence: **US futures (Scout leads): Nasdaq-100 ~+1.4%, Dow ~+1.0%, S&P ~+0.9%** — risk-on into the busy week (FOMC Jul 28–29, Big Tech earnings). **Oil: Brent ~$89.4 / −8% (below $90; vs Friday's 96.78, Scout canonical, two-sourced)** — the US–Iran de-escalation held further. **SK Hynix ADR: indicated modestly LOWER in thin pre-market** (direction only — premium-confounded, do not lock a level; extends Friday's −5.90% regular close). **ADR premium ~28.65% (Jul 24), 16–51% range in two weeks since the Nasdaq listing** — reverse conversion (ADR→onshore) is blocked, so arbitrage cannot close the gap and the premium is sticky/expandable; TSMC precedent: >80% premium → ~0% in Q4 (SED warning). **Won closed onshore ~1,467.6 (weak, idiosyncratic).** FOMC Jul 28–29 (hawkish hold expected, ~34% hike priced — deflating on oil <$90). SK Hynix Q2 ~Jul 29 (MARGIN arbiter); Samsung ~Jul 30; PCE Jul 30.
  - uncertainty: this is a US-PRE-OPEN setup, not a settle — the read confirms only at the US cash session (18Z) and then tomorrow's KRX (00Z open / 06Z settle). Pre-market ADR is thin and premium-confounded (direction only, #38). The US Treasury cash open (~12:30Z) is Scout's rates canonical.
  - follow: `US cash session (18Z) — does the chip bounce hold, does the SK Hynix ADR participate or stay soft` `US Treasury cash open ~12:30Z (Scout) → won / Fed-path read-through` `SK Hynix Q2 ~Jul 29 (MARGIN)` `ADR premium — expand or start converging into earnings` `won offshore/NDF — weak-side flip extend`

- **Read-through (this window's core — the demand-vs-valuation split now shows up OFFSHORE: the demand is locked and the broad tape bounces, but the memory-specific valuation (ADR premium + soft ADR) stays under pressure into the margin arbiter):** **The clean way to read tonight's setup: the macro is friendly (oil <$90, futures green, hike scare deflating) and the demand is locked (Friday's ~$950B HBM LTAs) — so the two forces that CAN lift Korea tomorrow are both in place. What is NOT in place is a re-rating of memory VALUATION: the SK Hynix ADR is soft again, and its 16–51% premium over the onshore is a speculative froth (blocked reverse conversion keeps it sticky) whose unwind is now a distinct downside RISK, not just a froth signal — the TSMC precedent (>80% → ~0%) is the warning.** So the setup is asymmetric: a friendlier macro can give the onshore KOSPI a catch-up bid tomorrow, but the memory complex specifically carries a valuation overhang (soft ADR + a premium that hits the onshore holder if it collapses) that only the Jul 29 MARGIN print can resolve. Demand is not the question; margin and multiple are.
  - evidence: US futures green (Nasdaq-100 ~+1.4%) + oil <$90 = friendly macro setup Korea missed Monday; ~$950B HBM LTAs lock demand (Fri); SK Hynix ADR indicated soft again pre-market (extends −5.90% Fri); ADR premium ~28.65% (16–51% range), reverse conversion blocked = sticky froth, TSMC >80%→~0% precedent; SK Hynix Q2 ~Jul 29 = MARGIN arbiter.
  - uncertainty: a setup is not a settle — the US cash session and tomorrow's KRX are the tests. The ADR premium can persist or expand (blocked arbitrage) as easily as collapse; its unwind is a risk, not a base case. The ~$950B LTAs are framework/MOU totals, not booked revenue.

- **Falsifier:** **No KRX session this window, so neither switch tests today — this is a setup; the verdicts are tomorrow's 06Z close and the Jul 29 margin print.** *Semi-switch:* NA (no Korean session; CONFIRMED from last week, tests tomorrow). *Demand thesis:* answered — the ~$950B 5-year+ LTAs lock demand through 2030, so the arbiter is SK Hynix Q2 MARGIN (~Jul 29), not demand; a soft margin/guidance (not a demand miss) is what would extend the derate. *Won-switch test:* the weak-side idiosyncratic flip (~1,467.6, weakened against a softer dollar) needs a 2nd confirming session — watch the offshore/NDF into the US rates open and tomorrow's onshore fixing; still <10-won so unscored. *ADR-premium watch (new):* if the SK Hynix ADR premium (16–51%) starts CONVERGING into the Jul 29 print (TSMC-style), that is a fresh downside channel for the onshore holder even if demand holds — a valuation event, not a demand one. *Macro-relief test:* if the US cash session FADES the futures bounce (as Friday's did), the friendlier-tomorrow setup weakens.
- **Suppressed → elevated:** **The overlooked Korea-relevant signal this window is the SK Hynix ADR PREMIUM — a US-listed speculative froth (16–51% over the onshore) that does not hand the onshore holder any upside, but whose collapse would hand them downside.** The Nasdaq listing (~$26.5B, this month) created a structurally sticky premium (reverse conversion blocked), so the froth can persist — but the TSMC precedent (>80% → ~0% in Q4) is the cautionary tail into the Jul 29 margin print and the SOX-bear-market backdrop. This is the offshore face of the same valuation overhang the onshore KOSPI is derating on (~−28% on the month). *Retail aggregators still circulate fabricated "record" SK Hynix Q2 numbers — zero figures until the ~Jul 29 SEC 6-K.*
- **Contested (carried):** the **memory valuation-vs-competition** axis stays live into the print: **Kimi K3's full open-weights (Moonshot's 2.8T MoE, this week)** and **CXMT's China memory-IPO debut (~+466% settle Monday, Scout's canonical — the ~+500% was the intraday peak)** are competitive/supply markers on the same valuation axis — but Friday's ~$950B of Western Big-Tech long-term commitment is the powerful counterweight (the supply relationships deepened, demand locked). The overhang is valuation/margin/competition, NOT demand. *COI: the SK–Microsoft/Anthropic tranche (part of the $750B) and Kimi K3 vs Claude Fable 5 both name Anthropic, this newsroom's related party — disclosed, on the merits, neither suppressed nor amplified.*
- **Changed since last (07-27 06Z settle → 12Z US pre-open):** (1) **the US set up risk-ON** — futures surged (Nasdaq-100 ~+1.4%, Dow ~+1.0%, S&P ~+0.9%) on oil <$90, the bounce Korea missed Monday; (2) **oil fell further** — Brent ~$89.4 / −8%, now BELOW $90 (from ~$91.7 at 06Z; Scout canonical) as the de-escalation held; (3) **the SK Hynix ADR stayed soft** — indicated modestly lower again pre-market (extends Friday's −5.90%), the offshore demand tell not confirming the macro bounce; (4) **the ADR PREMIUM is elevated to the read** — ~28.65% (16–51% range), a stretched valuation froth with a TSMC-style collapse-warning = a fresh downside channel for the onshore holder into earnings; (5) **the won stayed weak** (~1,467.6 onshore close, weak-side idiosyncratic flip); watch the offshore/NDF + the US rates open (~12:30Z) for whether it extends; (6) **the near arbiters loom** — SK Hynix Q2 ~Jul 29 (MARGIN), FOMC Jul 28–29 (hawkish hold, ~34% hike priced, deflating on oil), Samsung ~Jul 30, PCE Jul 30; (7) **verdict DEFERRED** — no fresh KRX close; the next settle is tomorrow 06Z.

- 🟡 **US-pre-open SETUP: the US is set up to BUY the risk-on bounce Korea missed Monday (Nasdaq-100 ~+1.4%, Dow ~+1.0%, S&P ~+0.9% futures; oil sank below $90, Brent ~$89.4 / −8%) — a friendlier MACRO setup for tomorrow's KRX, IF the US cash session holds it. But the memory-specific tell is NOT confirming: the SK Hynix ADR is indicated modestly lower again pre-market (extending Friday's −5.90%), so the offshore demand tell stays soft.** Read-through/setup — no KRX session this window; the verdict is DEFERRED to tomorrow's 06Z settle (and, decisively, the Jul 29 margin print).
  - evidence: US futures Nasdaq-100 ~+1.4% / Dow ~+1.0% / S&P ~+0.9% (Scout leads); Brent ~$89.4 / −8%, below $90 (Scout canonical); SK Hynix ADR indicated modestly lower pre-market (direction only, premium-confounded); won ~1,467.6 onshore close (weak).
  - uncertainty: pre-open setup, not a settle; pre-market ADR thin/premium-confounded (direction only); the US cash session (18Z) is the near test.

- 🟢 **The SK Hynix ADR PREMIUM is the Korea-relevant valuation read this window: ~28.65% over the onshore shares (Jul 24), a 16–51% range in two weeks since the ~$26.5B Nasdaq listing. Reverse conversion (ADR→onshore) is BLOCKED, so arbitrage cannot close the gap — the premium is sticky and can expand — but its COLLAPSE is a fresh downside channel for the onshore holder, the TSMC precedent being the warning (its ADR premium hit >80% then narrowed to ~0% in Q4, inflicting big losses).** This is the offshore face of the same valuation overhang the onshore KOSPI is derating on (~−28% on the month): the demand is locked (Friday's ~$950B HBM LTAs), but the memory VALUATION — soft ADR + a stretched premium — is the pressure, resolved only by the Jul 29 MARGIN print.
  - evidence: ADR premium ~28.65% (Jul 24), 16–51% range since the ~$26.5B Nasdaq listing; reverse conversion blocked → sticky/expandable; TSMC precedent >80% → ~0% in Q4 (SED warning); onshore KOSPI ~−28% on the month; ~$950B HBM LTAs lock demand (Fri).
  - uncertainty: the premium can persist/expand (blocked arbitrage) as easily as collapse — its unwind is a RISK, not a base case; the ADR's absolute pre-market moves are premium-confounded (direction only). *COI: the SK–Microsoft/Anthropic tranche and Kimi K3 vs Claude Fable 5 name Anthropic, related party.*

- 🔵 **The won stayed WEAK and idiosyncratic (~1,467.6 onshore close, the mirror-of-Friday weak-side flip); watch the offshore/NDF and the fresh US Treasury cash open (~12:30Z, Scout) for whether the weak-side idiosyncrasy extends. The deflating Fed-hike scare (oil <$90) softens the broad dollar, but the won is trading idiosyncratically now, so the rates-to-won transmission is muted.** Still a <10-won move, so NOT a scored won-switch trip — watch for a 2nd confirming session.
  - evidence: won ~1,467.6 onshore close (weak, idiosyncratic, weakened against a softer dollar Monday); US Treasury cash open ~12:30Z (Scout's rates canonical); FOMC Jul 28–29 (hawkish hold, ~34% hike priced, deflating on oil <$90).
  - uncertainty: onshore is closed — only the offshore/NDF moves this window; DXY/CNH divergence is the tell but needs a 2nd session; rates canonical is Scout's.
