Daily Pulse — August 3, 2026
Retail absorbed KRW 4.65T (~$3.26B) alone as foreign and institutional investors both sold. One session after the largest foreign inflow in this market’s history, the flow reversed.
KOSPI −5.12% | KOSDAQ +2.44% | Friday’s record foreign inflow reversed in one session
The Number That Matters
KRW 4.65T (~$3.26B). That is what retail absorbed on Monday, against foreign net selling of KRW 2.84T (~$1.99B) and institutional net selling of KRW 1.95T (~$1.36B) — 97.1% of the two professional cohorts combined, and 163.7% of the foreign leg on its own. One session earlier, foreign investors had bought a record KRW 8.77T (~$6.14B). The reversal took a single day.
Where the Money Actually Went
Foreign investors net sold KRW 2.84T (~$1.99B) in cash equities with futures flat at zero contracts. Their top five purchases were Hyundai Motor (+KRW 35.6B, ~$25M), Hyundai Mobis (+KRW 29.4B, ~$21M), NAVER (+KRW 26.0B, ~$18M), LG Innotek (+KRW 23.3B, ~$16M) and Hanwha Aerospace (+KRW 21.2B, ~$15M). No semiconductor name appears. SK hynix fell 8.80% to 1,567,000 won and Samsung Electronics 8.76% to 239,500 won, both surrendering roughly a third of Friday’s move. Samsung’s foreign ownership closed at 46.70%, its lowest since 2009. KOSDAQ rose 2.44% to 737.35 — a 7.56 point spread against KOSPI.
Why the Market Moved
Selling concentrated in the two names that produced Friday’s record session. The KOSDAQ divergence points to a large-cap semiconductor unwind rather than broad risk-off. Deposit-balance and global-indicator feeds failed to collect today, so no structural liquidity reading is available for this session.
The Uncomfortable Question
Alpha Signals #002 set a falsification test on Friday’s rally: foreign net turning negative during August 3–7 while SK hynix traded below its July 31 close of 1,718,000 won would reclassify that session as short-covering rather than re-entry. Both conditions were met on the first session available. That removes the marginal buyer the index had on Friday.
KoreaAlpha Take
Retail standing alone against both professional cohorts is the same structure as June 23. What is different is the speed: the largest foreign inflow in this market’s history lasted one session before reversing.
The bull condition set on Friday — foreign net buying positive for five consecutive sessions through August 7 — is now unreachable this week. The next scheduled event is August 19, when KRX tightens NAV divergence limits on single-stock leveraged products from 3% to 2% domestic.
