Daily Pulse: July 3, 2026
KOSPI +5.76% | KOSDAQ +0.19% | A 440-point rally with no net buyer
FACT. SK Hynix rose roughly 10.9% even as the Philadelphia semiconductor index fell 5.44%. The two names that drove the move, Samsung Electronics and SK Hynix, about 35% of KOSPI weight, never appeared on the foreign cash buy list.
FACT. Where foreign cash did go was selective and downstream: Samsung Electro-Mechanics +KRW 128.6B (~$84.1M), Daedeok Electronics +KRW 53.3B (~$34.9M), LG Innotek +KRW 52.2B (~$34.1M), Hyundai Motor +KRW 41.2B (~$26.9M), and Hyundai Mobis +KRW 29.0B (~$19.0M), components and substrates, not the index heavyweights.
FACT. Three catalysts framed the day. Bloomberg reported Korean authorities preparing for currency inflows tied to an SK Hynix US listing; USD/KRW firmed toward 1,520 from 1,555 two sessions earlier, beyond what a 0.64% DXY decline alone explains; and Samsung Electro-Mechanics disclosed a new subsidiary equity investment on DART, a name foreign capital had bought for three straight sessions.
VIEW. A 5.76% move that no investor class claims is not a recovery; it is index mechanics and short-covering filling a vacuum. The repatriation story is the real variable, and its direction is unresolved: if proceeds route into a USD-listed SK Hynix ADR, Korean investors capture the exposure without touching domestic equities, and the KOSPI loses index weight rather than gaining a foreign demand catalyst.
VIEW. Samsung Electronics reports Q2 earnings next week into a thinner floor, the retail investor deposit base has contracted from KRW 132.5T (~$86.7B) to KRW 120.1T (~$78.5B) since June 17.
Until they do, the rally has no owner.

[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 2026-07-03 was 1,529.0. All USD figures below have been recomputed; KRW figures are unchanged.
