Daily Pulse: July 8, 2026
KOSPI fell 5.35% and foreign investors turned net buyers for the first time in 14 sessions — but half of it was SK Hynix, with zero futures and matching institutional selling.
KOSPI -5.35% | KOSDAQ -5.56% | Foreign investors turned net buyers for the first time in 14 sessions, but half of it was one stock
The Number That Matters
KRW 331.6B (~$221M). That is what foreign investors net bought in KOSPI cash equities today, their first net buy in fourteen sessions, on a day the index fell 5.35% and the KOSDAQ lost 5.56%. After two weeks of relentless selling, the buy-side finally appeared. The question is whether this is a turn or a trap.
Where the Money Actually Went
The buy was not broad. Roughly half of the foreign net purchase, KRW 166.2B (~$111M), went into a single name: SK Hynix. The rest of the top five were Samsung Electro-Mechanics (+KRW 157.6B, ~$105M), LG Innotek (+KRW 109.4B, ~$73M), SK Square (+KRW 76.6B, ~$51M), and HD Hyundai Heavy Industries (+KRW 76.3B, ~$51M). This is not a sector coming back into favor, it is selective accumulation of one memory name and its supply chain, on the day US ADR-arbitrage flows around SK Hynix were in focus.
Why the Market Moved
- AI-rotation jitters: global funds trimmed semiconductor exposure after Samsung's earnings, sending Korean chip names lower even as China rallied.
- Middle East risk: an escalation around the Strait of Hormuz lifted oil and the dollar, pressuring risk assets and won-sensitive equities.
- The KOSDAQ broke below 800 for the first time in ten months, signalling the selloff had spread well beyond large-cap chips.
The Uncomfortable Question
Institutions sold KRW 347.9B (~$232M), almost exactly matching the foreign buy, meaning domestic desks handed stock to foreigners rather than a fresh bid arriving. And half the buy was one ticker. If foreign capital were truly turning, would it show up in a single name, without futures, against domestic selling of the same size?

KoreaAlpha Take
A KRW 331.6B foreign buy on a 5.35% down day looks like the bottom-fishing headline writers want. Underneath, it is one stock, no futures, and a matching institutional exit.
The fourteen-session foreign selling streak ended today, technically. But a return worth trusting looks different: it is broad across names, confirmed by futures, and met by domestic buyers adding rather than distributing. Today was none of those. SK Hynix alone absorbed half the flow while the KOSDAQ broke 800.
