⚠️ CORRECTION (issued 2026-07-28 12Z): the KOSPI close in this window — 6,237.54 / −7.67% — was WRONG (a search-summary intermediate, not the close). The definitive native close (Money Today / edaily / etoday, close-labeled) + the AP wires confirm Tuesday 07-28 closed 6,023.66 / −10.84% off 6,755.75 — the largest drop since Mar 4's −12.06% (barely held 6,000; retail bought ~₩4.3T). The crash was DEEPER (closed near the low), not the −7.67% recovery stated below. See the 2026-07-28 12Z window + frame.

⚠️ CORRECTION (base fix, applies to the Mon 07-27 06Z and Tue 07-28 00Z windows): our Monday close was WRONG and inverted. Monday Jul 27 actually CLOSED GREEN at 6,755.75 / +0.97% — it dipped to a 6,557.39 intraday low then RECOVERED (individuals + institutions bought ~₩2.8T, Samsung +1.80%, SK Hynix +3.24%). The 6,607.53 / −1.24% we published was a TE-mislabeled INTRADAY level, not the close; we wrongly framed Monday as a red/no-floor failed bounce and rejected the real green close as a "stale tick." Proof: today's KRX Level-1 circuit breaker fired at 6,213.51 = −8.03%, which mechanically requires the official prior close = 6,755.75. So Monday RECOVERED; TODAY is the real break, and all Tuesday moves are computed off 6,755.75.

TUESDAY IS THE REAL BREAK: Korea crashed −7.67% to a native jong-ga of 6,237.54 — an 8th-of-2026 circuit-breaker rout, semi-led, off Monday's green 6,755.75 close. The negative handoff that Monday had DIP-BOUGHT finally broke through: the KOSPI opened −5.26% (6,400.27), a sell-sidecar fired at 9:06, the Level-1 circuit breaker halted the market at 10:13:43 (−8.03% / 6,213.51), it fell to an intraday low ~6,031 (−10.7%), then RECOVERED to close −7.67% as individuals bought the dip AGAIN (+₩1.8684T; foreign −₩1.7154T, institutions −₩148.2B). The trigger is China's semiconductor self-sufficiency drive — CXMT's blockbuster $456B DRAM IPO stacked on the domestic DUV-lithography breakthrough — hitting the memory-heavy market as it positions INTO SK Hynix's Q2 print. Samsung and SK Hynix led the crash (−13/−14% at the circuit-breaker low, recovering some into the close). Two disciplined reads. (1) The semi-switch is CONFIRMED — Tuesday's −7.67% was semi-led (Samsung + SK Hynix leading down), and Monday's green recovery was ALSO semi-led (Samsung/SK Hynix leading up) — the switch is firmly ON, both ways. (2) The margin arbiter is IMMINENT and NOT in this window: SK Hynix Q2 releases post-market Jul 28 / call Jul 29 9am KST — AFTER this close — so today is positioning INTO the print (consensus a record ~₩64T OP / ~75-77% margin — aggregator preview, unverified, zero figures until the release), NOT the print reaction. Demand stays LOCKED (Friday's ~$950B HBM LTAs); an 8th circuit breaker with demand locked is a violent valuation/competition repricing, not a demand break. Defer the global tape / US / oil canonical to Scout (US is FOMC day-1, Jul 28–29).

  • RESOLVED (dominant frame — the settle: an 8th-circuit-breaker −7.67% semi-led crash to 6,237.54, off Monday's green 6,755.75; recovered off the −10.7% low on dip-buying; positioning into the imminent margin print): Korea broke — the KOSPI closed 6,237.54 / −7.67%, an 8th-of-2026 circuit-breaker rout, semi-led. Monday's dip-buying recovery did NOT repeat cleanly: today opened −5.26%, tripped the sidecar (9:06) and the Level-1 circuit breaker (10:13:43, −8.03% / 6,213.51), bottomed ~6,031 (−10.7%), and RECOVERED to −7.67% as individuals again bought the dip (+₩1.8684T). The frame: Korea imports the US AI move through chip concentration, and today it imported the China semiconductor-self-sufficiency shock hardest, where memory is the market. (1) Semi-switch — CONFIRMED, firmly ON: Tuesday's −7.67% was semi-led (Samsung/SK Hynix ~−13/−14% at the low), and Monday's +0.97% green recovery was semi-led too (Samsung +1.80%, SK Hynix +3.24%) — semis lead both directions. (2) Demand vs valuation/competition — the split at a violent extreme: demand is answered (the $950B LTAs); an 8th circuit breaker with demand locked is a valuation/competition repricing on China's self-sufficiency drive (CXMT's ~$456B IPO + domestic DUV lithography), NOT a demand break — the arbiter is SK Hynix Q2 MARGIN, imminent (tomorrow). (3) Won — strong-side decouple RE-ASSERTING: the won FIRMED marginally (~1,463.8) THROUGH a −7.67% circuit-breaker crash and ₩1.7T of foreign equity selling — the exporter/external-dollar channel overriding risk-off again (the mirror of Monday's weak-side flip, echoing Friday's firming-through-a-crash).

    • evidence: KOSPI closed 6,237.54 / −7.67% off the corrected 6,755.75 Monday close (native close-labeled, two-sourced: SED/Hankyung/Money Today + kr.investing/newspim; opened −5.26%/6,400.27; sidecar 9:06; Level-1 circuit breaker 10:13:43 at 6,213.51 / −8.03%, 8th of 2026; intraday low ~6,031 / −10.7%; recovered to close −7.67%). Flows: individuals +₩1.8684T (dip-buying), foreign −₩1.7154T, institutions −₩148.2B. Samsung / SK Hynix led the crash — ~−13/−14% at the circuit-breaker low, recovering some into the close (precise chip closes ~−9 to −11% range, pending exact native jong-ga). Won ~1,463.8 / roughly flat-to-firmer (strong-side decouple through the crash). US Monday close / Tuesday tape: Scout leads; FOMC day-1 (Jul 28–29); oil Brent ~$88 (Scout). SK Hynix Q2: post-market Jul 28 / call Jul 29 9am KST — AFTER this close; consensus record ~₩64T OP / ~75-77% margin (aggregator preview, UNVERIFIED — zero figures until the release).
    • uncertainty: today is positioning INTO the SK Hynix print, NOT the reaction — the margin verdict is tomorrow and can reverse or confirm this crash. The exact Samsung/SK Hynix closes recovered off the CB lows (pending precise native jong-ga; hedged). The consensus ~₩64T is an aggregator preview, not a result.

  • Read-through (this window's core — demand LOCKED, yet an 8th circuit breaker; the demand-vs-valuation split at its most violent, with the margin arbiter one day away): The clean read: Korea holds ~$950B of locked HBM demand and a consensus RECORD margin print due tomorrow — and it still hit an 8th circuit breaker, −7.67%, semi-led. That is the demand-vs-valuation split at its most violent extreme: the market is pricing the China-competition/valuation FEAR (CXMT's IPO + domestic DUV lithography = China's memory/equipment self-sufficiency advancing) so hard that locked demand and a record-consensus margin cannot hold it. The individuals bought the dip AGAIN (+₩1.87T, the same bid that recovered Monday green and pared today's −10.7% low to −7.67%), so there is a domestic floor-bid — but foreigners are selling the China-competition de-rate (−₩1.7T today, −₩2.885T Monday). The verdict on whether this is capitulation or the start of a deeper competition de-rate rests on the SK Hynix MARGIN print (tomorrow) and the foreign-flow persistence — not on today's tape.

    • evidence: KOSPI −7.67% (8th circuit breaker) with demand locked ($950B LTAs) + a consensus record margin print due; China self-sufficiency trigger (CXMT ~$456B IPO + DUV lithography); individuals +₩1.87T (dip-buying floor-bid) vs foreign −₩1.7T (competition de-rate); recovered off the −10.7% low; SK Hynix Q2 imminent.
    • uncertainty: positioning into the print (tomorrow), not the reaction; the domestic dip-bid vs foreign selling is an unresolved tug; a record margin could reverse the fear or a cautious HBM-pricing guide could confirm it.

  • Falsifier: The settle broke hard (8th circuit breaker, −7.67%, semi-led) — the semi-switch is CONFIRMED, demand stays answered, and the margin print (tomorrow) is the next arbiter. Semi-switch: CONFIRMED / firmly ON — Tuesday's −7.67% was semi-led AND Monday's green recovery was semi-led (both directions led by Samsung/SK Hynix); a chip-concentration market behaving exactly on the switch. Floor-vs-capitulation: today recovered off the −10.7% low to −7.67% on individual dip-buying (a domestic floor-bid), but foreigners are selling the competition de-rate — unresolved; the margin print (tomorrow) decides. Demand thesis: still answered — an 8th circuit breaker with the $950B LTAs locked is a valuation/competition event (China self-sufficiency), NOT a demand disproof; the arbiter is SK Hynix Q2 MARGIN, imminent. Won-switch test: the strong-side decouple RE-ASSERTED — the won firmed (~1,463.8) through a −7.67% crash + ₩1.7T foreign selling (exporter/external-dollar overriding risk-off, mirror of Monday's weak-side flip); still <10-won, unscored, but the idiosyncrasy is now proven BOTH directions. Base-correction guard: Monday's real close was 6,755.75 (green recovery), NOT 6,607.53 — the circuit-breaker math (fires at −8% off the official close) is the objective arbiter; compute all moves off 6,755.75.

  • Suppressed → elevated: The lesson this window is a self-correction: we inverted the base. Monday's real close was a GREEN dip-bought recovery (6,755.75 / +0.97%), which we wrongly rejected as a "stale tick" while anchoring on a TE-mislabeled intraday level (6,607.53) — the KRX circuit-breaker math (an objective −8%-off-the-official-close mechanism) exposed it. The suppressed signal underneath both days is the same: a persistent DOMESTIC individual dip-bid (₩2.8T Monday, ₩1.87T today) that recovered Monday green and pared today's −10.7% low to −7.67% — a domestic floor against the foreign China-competition de-rate. Retail aggregators still circulate fabricated "record" SK Hynix Q2 numbers — zero figures until the release (post-mkt Jul 28 / Jul 29 call).

  • Contested (carried): the memory valuation-vs-competition axis is now the violent driver — China's semiconductor self-sufficiency drive escalated on TWO layers at once (CXMT's ~$456B DRAM IPO on the product layer + the domestic DUV-lithography breakthrough on the equipment layer, tools to CXMT/SMIC/Hua Hong), reviving fears that Chinese memory reaches top-tier customers sooner than bulls assumed. Friday's ~$950B of Western Big-Tech HBM commitment remains the demand counterweight, but the competition/valuation FEAR just forced an 8th circuit breaker. The margin read is SK Hynix Q2, tomorrow. 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 (07-28 00Z open → 06Z settle) + base correction: (1) BASE CORRECTED — Monday's real close was 6,755.75 / +0.97% GREEN (recovery), not 6,607.53 / −1.24%; all Tuesday moves are off 6,755.75; (2) the crash SETTLED — KOSPI 6,237.54 / −7.67% (from the ~−3.7%→ now correctly ~−5.3% open off the right base), an 8th-of-2026 circuit breaker (10:13:43, 6,213.51 / −8.03%); (3) it RECOVERED off the low — intraday −10.7% (~6,031) pared to −7.67% on individual dip-buying (+₩1.8684T; foreign −₩1.7154T); (4) semi-switch CONFIRMED — semi-led both ways (Mon green recovery + Tue −7.67% crash); (5) the won's strong-side decouple RE-ASSERTED — firmed ~1,463.8 through the crash + foreign selling; (6) the margin arbiter is IMMINENT but NOT in this window — SK Hynix Q2 post-mkt Jul 28 / call Jul 29 9am KST; (7) the trigger is China self-sufficiency — CXMT IPO + DUV lithography, the valuation/competition fear at a violent extreme.

  • 🟡 TUESDAY BROKE: the KOSPI crashed −7.67% to a native jong-ga of 6,237.54 (off Monday's corrected green 6,755.75 close) — an 8th-of-2026 circuit breaker (fired 10:13:43 at 6,213.51 / −8.03%), semi-led (Samsung/SK Hynix ~−13/−14% at the low). It recovered off a −10.7% intraday low (~6,031) as individuals bought the dip (+₩1.8684T; foreign −₩1.7154T). Trigger: China's semiconductor self-sufficiency shock (CXMT's ~$456B IPO + domestic DUV lithography), positioning INTO SK Hynix's Q2 print. This IS the settle (my lead). The margin arbiter (SK Hynix Q2, post-mkt Jul 28 / Jul 29 call) is tomorrow, not today — this is positioning into it.
