KOSPI –7.89 percent to 7,648.09 on the second Black session in eleven days. Foreign KRW 5.13T out, retail KRW 5.40T in — but foreign's top-five buy list carries under 6 percent of KOSPI 200 weight. The composition is the tell.

KOSPI 7,648.09 (, 7.89 percent, 655 points). KOSDAQ, 6.74 percent. The second single-session decline above five percent in eleven trading days.
FACT
Foreign capital net-sold KRW 5.13T (~$3.3B) on the cash tape. Institutional investors added KRW 0.48T (~$0.3B) of net selling. Retail net-bought KRW 5.40T (~$3.5B), absorbing 105 percent of the foreign exit alone, and 96 percent of the combined foreign-plus-institutional exit.
The single largest KOSPI decliner: SK Hynix, 14.57 percent. Global comparison: Philadelphia Semiconductor Index (SOX), 6.27 percent, NASDAQ Composite, 0.66 percent. Korea absorbed the semiconductor repricing at roughly twelve times the US market's decline rate.
Retail investor deposit balance: KRW 121.6T (~$78.8B)down from KRW 132.5T (~$85.9B) at the start of the current sequence. A drain of KRW 10.9T (~$7.1B) in eleven sessions.
KoreaAlpha VIEW
The domestic absorption is not without a ceiling. Every session foreign capital continues to net-sell while institutional capital declines to co-buy, retail deposit balance moves further toward the threshold at which a single additional shock session at today's magnitude cannot be absorbed. Today's KRW 5.40T retail deployment was drawn from a deposit base already KRW 10.9T smaller than the one that absorbed the first comparable session on 23 June.
Foreign capital did not disengage from Korea today, the top five foreign cash purchases totaled KRW 348.1B (~$226M). Their composition, however, was highly selective: no Samsung Electronics ordinary shares, no SK Hynix, and combined KOSPI 200 weight under six percent. That structural pattern, foreign capital buying outside the index while selling the index, is the subject of Alpha Signals #001published today.
WATCHPOINT
Retail investor deposit balance crossing below KRW 115T (~$74.6B) before foreign futures register a single net long contract, the point at which the domestic absorption ceiling has thinned from a depleted base.

[Correction, 2026-08-05] This post previously described foreign futures positioning. Our data pipeline recorded a collection failure as a zero value, so those figures, and any consecutive-session counts derived from them, were unsupported. The affected sentences have been removed.
[Correction, 2026-08-08] USD conversions in this post were computed at approximately KRW 1,380 per USD, a fallback constant our pipeline recorded when exchange-rate collection failed, not a market rate. The actual USD/KRW close on 2026-07-02 was 1,542.5. All USD figures below have been recomputed; KRW figures are unchanged.
