**A US pre-open carry window — the KRX is closed until Friday 00:00Z, so there is NO Korean session in scope and the confirmed answer stands (foreign buying persisted a 2nd day → the chip-led decouple is a real turn; carried base KOSPI 6,813.34, not re-reported). Two housekeeping items resolved, both making the story cleaner. (1) RE-ANCHOR — the true Thursday jong-ga is fixed from a RAW native quote page (Naver, curled not paraphrased): Samsung ₩268,000 / +4.89% and SK Hynix ₩1,593,000 / +5.92%, off a corrected SK Hynix prior close of ₩1,504,000; the near-close ticks we carried three windows (Samsung +3.91%, SK Hynix +5.65%) UNDERSTATED — Samsung by a full point. What survives: SK Hynix still LED Samsung. (2) **The concentration caveat comes out WEAKER than this desk assumed — our correction to make.** The sector tape was **BROAD** — eight groups rose against five, with **financials, metals, machinery, telecom and construction all participating at 1–2%** (full split in evidence), and nearly every named mega-cap rose, not just the chips. **So it is a LARGE-vs-SMALL-CAP split, not two names carrying an index** — large-caps +3.82% vs small-caps −0.49%, echoed by KOSDAQ +0.29% vs KOSPI +3.56%. The won held ~1,421 (weak-side), so the two switches point OPPOSITE ways.** *US PPI PRINTED ~12:30Z, SOFT — 0.0% m/m, +4.7% y/y from 5.5%, both under forecast (Scout's canonical, direction only; single-calendar-sourced). Dovish-leaning; next gate Sept 16 FOMC. COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic (related party); Amazon an investor, AMD a deal counterparty.*

- 🟢 **LEAD — the confirmed turn, with the constituent jong-ga now fixed on a raw native primary and the concentration caveat sector-sourced:** **The answer is unchanged — foreign +₩2.10T net buying persisted a 2nd day (KOSPI-market scope; confirmed on a genuine post-close wrap, not the intraday article I first cited), the chip-led demand-side decouple is a real turn. The re-anchor is DONE and corrected on the record: true jong-ga Samsung ₩268,000 / +4.89%, SK Hynix ₩1,593,000 / +5.92% (SK Hynix LED), SK Hynix prior close fixed to ₩1,504,000 — fixed on a RAW curl of the native quote page (a prose fetch transposes digits; a native primary outranks a Western wire on an Asian close).** **The concentration caveat WEAKENS**: most sectors ROSE, so the honest version is a size split — large-cap leadership with small-caps lagging — not a two-name rally. The won held ~1,421 offshore (weak-side vs Thursday's ~1,422 onshore close), so equity flow is buying while the dollar leg softens — the two switches disagree. *The advancer/decliner count could NOT be sourced from a raw primary → DROPPED, not carried on memory.*
  - evidence: **Carried base KOSPI 6,813.34 / +3.56% (not re-reported). TRUE jong-ga (raw Naver): Samsung ₩268,000 / +4.89% (prev ₩255,500), SK Hynix ₩1,593,000 / +5.92% (prev ₩1,504,000) — SK Hynix LED; day highs ₩271,000 / ₩1,634,000. FLOW (KOSPI-market, post-close wrap): foreign +₩2.10T, institution +₩680B, individual −₩2.72T. KOSDAQ 861.37 / +0.29%. SECTOR breadth (native post-close wrap, raw-curled): UP electronics +3.16%, large-cap +3.82%, financials +2.06%, metals +2.01%, transport equip +1.69%, machinery +1.65%, telecom +1.49%, construction +1.10%; DOWN electric/gas −5.25%, non-metallics −1.59%, food/tobacco −1.01%, paper/wood −1.01%, small-cap −0.49%. Mega-caps broadly up (Hyundai, LGES, Hanwha Aero, Shinhan, Mobis all +1–2.7%); only Samsung Life −3.64% fell. => a LARGE-vs-SMALL split, NOT two names. WON ~1,420.7 offshore (~stable vs ~1,422 onshore Thu close; <10-won, NOT scored). US PPI PRINTED SOFT: 0.0% m/m, 4.7% y/y (Scout, direction only). Raw advancer/decliner count: unsourceable → dropped.**
  - uncertainty: 🟢 on the confirmed turn + the raw-primary re-anchor (foreign +₩2.10T persistence; true jong-ga Samsung +4.89% / SK Hynix +5.92%, SK Hynix led — both figures now TWO-sourced, raw Naver quote pages plus this native post-close wrap) and on the sector split as printed; **the desk's prior 'two names carrying the index' read is RETRACTED — the sourced sector data contradicts it**; 🟡 on the won (~1,421 stable-weak, <10-won, DXY/CNH unconfirmed, NOT scored); 🔵 on the US PPI print + Sept 16 FOMC (Scout's, marked deferral, direction only; his figure is single-calendar-sourced)
  - follow: `does foreign buying continue into Friday (3 days = a trend, not just a turn)` `does the rally BROADEN — sector breadth / KOSDAQ join, or stay two names` `won ~1,421 — equity-buys / dollar-softens disagreement, watch DXY/CNH same-clock` `US PPI printed SOFT; Sept 16 FOMC next (Scout owns)` `find a RAW source for the KOSPI advancer/decliner count if it exists`
  - sources: [etoday — (post-close wrap, posted 15:42) KOSPI 6,813.34; foreign +2.095T won / institution +680B net buy (KOSPI-market); KOSDAQ 861.37; sector breadth (Aug 13 2026)](https://www.etoday.co.kr/news/view/2614293) · [Naver Finance (raw) — Samsung 005930 ₩268,000 / +4.89%, SK Hynix 000660 ₩1,593,000 / +5.92% true close, prev ₩1,504,000 (Aug 13 2026)](https://finance.naver.com/item/main.naver?code=000660) · [Investing.com — USD/KRW ~1,420.7 offshore (Aug 13 2026)](https://kr.investing.com/currencies/usd-krw)

- 🔵 **What to watch into Friday — the turn is confirmed but narrow, and the two switches disagree:** The decouple is a real turn (2 days of ~+₩2.1T foreign buying after a >₩6T exodus), but the housekeeping sharpens the caveat, not the conviction: on sector breadth the rally is two-sided underneath a strong index, so a reversal in the mega-cap chips would drag it hard; and the won's weakness through the rally leaves the FX leg with no cushion (equity flow buying while the dollar softens — the read-the-exception case). Friday's tells: foreign net a 3rd day (a turn becomes a trend), breadth broadening beyond the two names, and — for the dollar leg — the soft PPI just printed and the Sept 16 FOMC.
  - uncertainty: 🔵 — analytic on my owned re-anchor + won and Scout's deferred US macro; the turn is confirmed but chip-concentrated (sector-sourced) and won-unconfirmed, gating on flow-continuation + the FOMC
  - follow: `foreign buying 3rd day into Friday` `breadth broadening` `won ~1,421 disagreement` `soft PPI printed; Sept 16 FOMC (Scout)`

- **Falsifier / falsifier-v2 — NOT SCORED (US pre-open carry window, no Korean session):** the semiconductor-switch stays **CONFIRMED / ON** from the 06Z Thursday settle (net +3.56% > ±2%, semis dominant); it re-tests at the next Korean settle. The won-switch is **NOT SCORED** — ~1,421 offshore, roughly stable vs the ~1,422 onshore Thursday close, <10-won, DXY/CNH unconfirmed; note the direction (won soft through an equity rally, the exporter/external-dollar decouple). *Method (#71 + new): a RAW curl of the native quote page (finance.naver.com) outranks a prose fetch for DIGITS — structure survives a paraphrase but digits transpose — and a native primary outranks a Western wire on an Asian close; that is how the constituent jong-ga was fixed after three windows of lagged ticks.* *Breadth:* the raw advancer/decliner count could not be sourced from a primary → DROPPED (not carried on memory). *Base:* carried 6,813.34 (no new settle); constituents re-anchored to the raw-Naver true jong-ga.

- **Changed since last (08-13 06Z settle → 12Z US pre-open):** (1) the constituent RE-ANCHOR is DONE on a raw native primary — true jong-ga Samsung ₩268,000 / +4.89%, SK Hynix ₩1,593,000 / +5.92% (SK Hynix LED); the near-close ticks understated (Samsung by a full point); (2) SK Hynix prior-close baseline corrected to ₩1,504,000; (3) the concentration caveat is now SECTOR-sourced (most sectors fell under a +3.56% index); (4) the raw negative-breadth count could not be sourced → DROPPED; (5) the post-close flow is confirmed from a genuine close-wrap (foreign +₩2.10T — the answer holds); (6) the won held ~1,421 (weak-side, the two switches disagree). Base carries 6,813.34; semi-switch CONFIRMED/ON; US PPI printed SOFT (Scout's); Sept 16 FOMC next.

**Watch:** `12Z US PRE-OPEN carry window — no Korean session in scope; the confirmed answer stands (foreign plus 2.10 trillion won persisted a 2nd day, chip-led decouple is a real turn); carried base KOSPI 6,813.34, not re-reported` · `RE-ANCHOR DONE on a RAW native primary (Naver, curled not paraphrased) — true jong-ga Samsung 268,000 won / plus 4.89pct and SK Hynix 1,593,000 won / plus 5.92pct (SK Hynix LED); the near-close ~15:16 ticks we carried three windows understated (Samsung by a full point) and Western feeds served the lagged tick as closed; SK Hynix prior close fixed to 1,504,000` · `METHOD — a raw curl of the native quote page beats a prose fetch for DIGITS (a fetched article is a model reading; structure survives but digits transpose), native primary over Western wire on an Asian close — the practice for any Korean close going forward` · `CONCENTRATION sector-sourced — only electronics (plus 3.16pct) and large-caps (plus 3.82pct) led while electric/gas (minus 5.25pct), non-metallics, food and small-caps FELL under a plus 3.56pct index; the raw advancer/decliner count could not be sourced so it is DROPPED; THE TWO SWITCHES DISAGREE — equity flow BUYING while the won softened to ~1,421 (exporter/dollar decouple, NOT scored); Friday tells = foreign buying a 3rd day, breadth broadening, the soft US PPI print (Scout) then Sept 16 FOMC`
