Daily Pulse: October 1, 2026
KOSPI +1.95% | KOSDAQ +4.48% | KOSPI opened at 6,814, closed at 6,971, 0.01 points below the session high of 6,971.36: foreigners and institutions bought in the same direction for the first time in four sessions, yet SK Hynix drew KRW 218B (~$160M) in foreign selling while absorbing KRW 48B (~$35M) in institutional buying
The Number That Matters
The KOSPI closed at 6,971.35, 0.01 points below the session high, reversing from a low of 6,765.06, a 3.0% recovery off the session floor. Foreign investors bought KRW 356B (~$262M) net in cash while selling 428 futures contracts, the two legs moving in opposite directions. The single largest foreign purchase was KRW 638B (~$468M) in Woori Financial Group, which alone exceeded total foreign net cash buying.
Where the Money Went
Foreign buying concentrated in Woori Financial Group at KRW 638B (~$468M), Samsung Electro-Mechanics at KRW 126B (~$93M) and Samsung Electronics preferred shares at KRW 88B (~$64M). Foreign selling hit SK Hynix at KRW 218B (~$160M) and Samsung Electronics at KRW 199B (~$146M). Institutions bought KRW 893B (~$655M) net; financial investment led at KRW 427B (~$314M), with private equity at KRW 199B (~$146M), investment trusts at KRW 158B (~$116M) and pension funds at KRW 96B (~$71M). Program trading sold KRW 179B (~$131M) net, with non-arbitrage at KRW 164B (~$120M). Retail sold KRW 2.19T (~$1.6B) net, with SK Hynix at KRW 905B (~$664M) the single largest exit. Samsung Electro-Mechanics was the only name where foreign and institutional conviction overlapped, with retail selling KRW 233B (~$171M) into both.
Why the Market Moved
1. Foreign and institutional cash moved in the same direction; Samsung Electro-Mechanics drew simultaneous conviction buying from both investor types.
2. Retail sold KRW 2.19T (~$1.6B) net, with SK Hynix and Samsung Electronics accounting for KRW 1.26T (~$925M) of that exit; institutions absorbed KRW 48B (~$35M) of SK Hynix against retail's KRW 905B (~$664M) sell.
3. US 10-year yields stood at 5.29%, a background level rather than a measured cause of today's moves.
The Uncomfortable Question
Foreign net cash buying on this session was KRW 356B (~$262M). A single stock, Woori Financial Group, drew KRW 638B (~$468M) in foreign buying. Strip out that one name and foreigners were net sellers of Korean equities. Whether a financial-sector rotation constitutes a return to Korean equities or a one-session reallocation within a continued semiconductor exit cannot be read from this data.
KoreaAlpha Take
The data does not support a broad recovery. Foreign net buying of KRW 356B (~$262M) was entirely explained by one financial stock; the two semiconductor names drew a combined KRW 417B (~$306M) in foreign selling. The watchpoint carried from prior sessions, whether foreign net cash in SK Hynix turns positive, came in at negative KRW 218B (~$160M). The two semiconductor buyback programs, SK Hynix running to 19 November and Samsung Electronics to 21 November, are the price-insensitive buyers absorbing this selling. The trade is simple: watch whether foreign net cash in SK Hynix turns positive in the next session.
