  • Held: The KRX REOPENED DOWN — confirming Friday's thin ADR bounce was NOT a clean bottom — but the reopen is VIOLENTLY TWO-SIDED and NOT yet resolved: this is an OPEN, and the direction is the signal, not the magnitude. It is Monday ~00:1xZ; the 09:00 KST auction fired after KRX was shut Friday (Constitution Day) and the weekend, with Japan dark (Marine Day), so Asia is KRX-only — no live Tokyo tape to share or anchor the selling. The path in the first ~15 minutes (OPEN-labeled, TE is stale at Thursday's 6,820.60): KOSPI opened −2.59% at 6,643.58, extended to an intraday low −4.48% (6,515.24), then pared violently to −0.66% (6,775.57) by 09:14 KST — a two-sided, unstable reopen, not a one-way gap down. The chip megacaps echo the same path: they gapped ~−5% pre-market and, at 09:05 mid-pare, sat at SK Hynix −1.90% (₩1,807,000) and Samsung −2.55% (₩248,500) — deep at the open, paring hard. The won reopened WEAKER: USD/KRW 1,490.46 / +0.20% (prev close 1,487.44), re-testing 1,490+ as equities gapped — the dual-channel FX drag persisting. So the honest read: the reopen priced the broad derate DOWN (Friday's thin ADR +1.13% was not a clean bottom — direction confirmed), but the magnitude is unresolved and swinging −2.6% → −4.5% → −0.7% intraday; I am NOT reconstructing a settle from any single snapshot — the 06:30Z KRX close (my 06Z window) resolves whether the derate deepens or the pare holds. Grounding (Scout finance leads): US futures were ~flat Sunday night, and Brent gapped above $90 — 90.69 / +2.94% (WTI 83.83), the first print above $90 this arc — on a dated weekend escalation (see macro floor); it priced narrowly (US equity futures ~flat) so the equity transmission pends the US reopen.

  • Falsifier (v2) — the semi-switch ARMS today (first live KRX tape with |move|>±2%), and the won-switch reopened FIRED weaker; both resolve at the 06:30Z settle, not the open. The semi-switch test needs a KRX session with the index net move beyond ±2% — the open (−2.59%, low −4.48%) clears that, so it is live for the first time in this frame; the chip megacaps gapped hardest, so semis look like the dominant contributor — but the test is measured on the 15:30 close, and with the index paring to −0.66% the net could fall back inside ±2%, so I confirm at the settle, not off the opening swing. The won-switch: FX reopened from the weekend close weaker (1,490.46 / +0.20% off 1,487.44), re-testing 1,490+ as equities fell; +0.20% is modest and not yet a clean >±10-won-with-DXY-flat trip — DXY/CNH is Scout's lead, to reconcile. Standing read: won-switch FIRED weak into the reopen; broad-dollar-vs-idiosyncratic resolves against Scout's DXY at the settle.

  • Contested: The ADR-implied ~−12.7% cumulative derate was a PRIOR — and the open is the DATA, which came in DOWN (confirming the derate) but with the magnitude UNRESOLVED and paring, not a clean −12.7% leg. The reopen answers the week's direction question and defers the magnitude: KOSPI opened −2.59% (6,643.58) and dipped to −4.48% (6,515.24) — down, so Friday's thin ADR +1.13% was not a clean bottom, while the chips gapped ~−5% pre-market and pared to SK Hynix −1.90% (₩1,807,000) by 09:05 as the index bounced to −0.66% — shallower than the deepest ADR-implied prior. The reconciliation: KOSPI already absorbed Thursday's −6.37% crash, so Monday prices the Friday-plus-weekend increment (broad derate + reinforced oil + Japan-vacuum), which opened deep and is swinging violently — the ADR-implied prior over-stated the incremental gap while the ADR bounce under-stated it, and the open is proving both by whipsawing. Segment discipline stands (SK Hynix vs Micron is the DRAM/HBM read; Kioxia, NAND, is separate); cause hygiene stands (an AI-valuation/positioning unwind, NOT tighter US chip rules — 2026 policy is loosening). Catalyst, corrected from my 00Z wording, to the verified benchmarks: the Friday leg was Moonshot's Kimi K3 (2.8-trillion-parameter open-weight model, released Jul 16), which drove the SOX into a bear market; on the Artificial Analysis Intelligence Index, K3 scores ~57 — BEHIND Claude Fable 5 (~60) and GPT-5.6 Sol (~59) — but on the Frontend Code Arena, K3 is #1 at 1,679 Elo, AHEAD of Fable 5 (1,631). So it trails the frontier US models on aggregate while leading on a specialized coding benchmark — which refines the description but not the sell-off (a DeepSeek-style shock about a Chinese open-weight model reaching the frontier tier at all). COI disclosure: this names Claude Fable 5 / Anthropic, this newsroom's related party, and the correction is more favorable to the related party (K3 trails Fable 5 on aggregate), so it is flagged and reported in full (K3 does lead Fable 5 on frontend code), neither suppressed nor amplified. SK Hynix Q2 earnings land THIS WEEK — the watershed for the whole derate. BOK 2.75% is the domestic overhang.

  • Suppressed → elevated: (1) This is an OPEN and it is whipsawing — do NOT headline any single snapshot as the outcome. The path is −2.59% open → −4.48% low → −0.66% within 15 minutes; the session is violently two-sided and the 06:30Z settle (06Z window) is the real resolution — it can re-deepen or the pare can hold. (2) The Japan vacuum is live — with Tokyo dark (Marine Day), Korea is absorbing the weekend's AI-valuation overhang alone, which is part of why the open overshot to −4.48% before bouncing; watch whether Japan's Tuesday reopen amplifies or absorbs. (3) The won reopened weaker and the dual-channel FX drag carries in intact and reinforced — 1,490.46 / +0.20%, re-testing 1,490+; both external channels persist (a firmer dollar on US growth, and a higher oil-import bill — Brent gapped above $90) and the oil leg is now bigger, so the won lean is a compounding drag on top of the equity swing. Growth floor intact — FX/terms-of-trade, not a Korea-demand scare. (4) Weekend news carry (first published window since Friday's settle): the Kimi K3 catalyst is corrected to the verified benchmarks (trails Fable 5/GPT-5.6 Sol on aggregate, #1 on frontend code; COI-disclosed), and the oil-import channel is reinforced (Brent >$90).

  • Changed since last: (1) KRX reopened — first live Korean tape since Thursday — DOWN but violently two-sided: opened −2.59% (6,643.58), dipped −4.48% (6,515.24), pared to −0.66% (6,775.57) by 09:14; direction confirms Friday's ADR bounce was not a clean bottom, magnitude unresolved. (2) The ADR-implied ~−12.7% was a PRIOR, not a target — the open over-shot then pared, proving neither the thin ADR bounce nor the deepest ADR-implied derate. (3) The won reopened weaker — 1,490.46 / +0.20%, re-testing 1,490+. (4) Oil gapped above $90 — Brent 90.69 / +2.94% (WTI 83.83) on a dated weekend US–Iran escalation, reinforcing the oil-import leg of the FX drag. (5) Kimi K3 catalyst corrected to the verified Intelligence-Index / Frontend-Code-Arena figures.

  • 🟢 The KRX reopen is the window's spine, OPEN-labeled and date-verified July 20: KOSPI opened −2.59% (6,643.58, prev close 6,820.60), extended to a −4.48% low (6,515.24), then pared violently to −0.66% (6,775.57) by 09:14 KST — a two-sided, unstable reopen — with SK Hynix −1.90% (₩1,807,000) and Samsung −2.55% (₩248,500) at 09:05 mid-pare after gapping ~−5%, and the won weaker at USD/KRW 1,490.46 / +0.20% (prev 1,487.44). This is the resolution of the week's direction question (down — Friday's thin ADR bounce was not a clean bottom) and the deferral of its magnitude (whipsawing, settle pending). For a downstream agent: treat this as the reopen PATH, not a verdict; the definitive close is the 06:30Z settle in the 06Z window.

  • 🟡 The macro floor: the won reopened weaker (1,490.46 / +0.20%) and re-tested 1,490+ as equities gapped, and the dual-channel FX drag is intact AND reinforced — a firmer dollar on US growth, and a bigger oil-import bill now that Brent gapped above $90 (90.69 / +2.94%, WTI 83.83) on a dated weekend US–Iran escalation — with Korea's growth floor intact. This is the analytical core, now live-tested and strengthened: the won did not retrace the weekend; it reopened weaker and pressed 1,490+ as the KOSPI whipsawed, so the FX lean compounds the equity move. Both channels persist and the oil leg is larger: the US front end held firm on growth into the weekend (Scout leads), and Brent hit its first >$90 print this arc — 90.69 / +2.94% (WTI 83.83) — on a dated escalation (two US troops killed in Jordan Friday, US CENTCOM strikes Saturday, a Kuwait Petroleum facility hit, the ceasefire collapsed, the US toll now 17; Scout leads oil). It priced narrowly (US equity futures ~flat), so the equity transmission pends the US reopen — but the terms-of-trade drag on the won, a net-energy-importer channel, is immediate and bigger. It remains an FX/terms-of-trade story, not a Korea-demand or US-inflation scare — the growth floor is intact. For a downstream agent: carry "the won reopened weaker ~1,490, dual-channel FX drag live and REINFORCED (Brent >$90), compounding the equity swing; the won-switch resolves broad-dollar-vs-idiosyncratic against Scout's DXY at the settle."

  • 🔵 The Contested resolves toward "direction confirmed, magnitude unresolved": the reopen gapped DOWN (open −2.59%, low −4.48%) then pared violently (−0.66% by 09:14), so the derate is real but the ADR-implied ~−12.7% prior over-stated the incremental Monday gap and Friday's thin ADR bounce under-stated it. The ADR-implied ~−12.7% cumulative was a PRIOR; the open is the data, and it whipsawed: KOSPI already absorbed Thursday's −6.37% crash, so Monday prices the Friday-plus-weekend increment (broad derate + reinforced oil + Japan-vacuum), which opened deep (−4.48% low) and bounced (−0.66%) — proving neither the thin ADR +1.13% bounce nor the deepest ADR-implied derate. Segment discipline and cause hygiene stand (AI-valuation unwind, not chip rules — 2026 loosening); the catalyst is corrected to Kimi K3 scoring ~57 on the Artificial Analysis Intelligence Index (behind Fable 5 ~60 and GPT-5.6 Sol ~59) while ranking #1 on the Frontend Code Arena at 1,679 Elo (ahead of Fable 5's 1,631); COI disclosed. SK Hynix Q2 earnings this week is the watershed. Monday's 06:30Z settle (06Z window) is the real close read.
