Context This is a KOSDAQ-focused follow-up to Korea Has Liquidity, But Breadth Has Broken, Korea Foreign-Investor Playbook: KOSPI 168, KOSDAQ 355, and KOSDAQ Smart Money Return.
TL;DR
KOSDAQ weakness should not be read as “foreigners sold.” Based on the provided local Kiwoom DB cut, foreigners were net buyers. The market still fell because foreign buying was narrow, ADR collapsed, and domestic institutional real money kept selling.
KOSDAQ is still up 8.5% YTD as of June 2, 2026, but it is down 16.3% from the April 27 high and fell 15.5% in May. The practical question is not whether KOSDAQ is cheap. It is whether real-money institutions are ready to return.
1. Price: The Problem Is the Post-April Drawdown
| Item | KOSDAQ |
|---|---|
| 2026-01-02 close | 945.57 |
| 2026-06-02 close | 1,026.03 |
| YTD return | +8.5% |
| 2026-04-27 high | 1,226.18 |
| Drawdown from high | -16.3% |
| May return | -15.5% |
The precise statement is: KOSDAQ did not collapse for the full year; it sold off sharply after its late-April high.
2. Flow: Foreigners Bought, Domestic Flows Pressured Breadth
Units: KRW 100 million, local Kiwoom DB through June 2, 2026.
| Period | Foreigners | Institutions | Individuals | Other corporates |
|---|---|---|---|---|
| YTD | +55,399 | +80,131 | -90,492 | -45,515 |
| May | +28,608 | -23,516 | +11 | -5,624 |
| Recent 20D | +34,930 | -18,992 | -10,473 | -6,096 |
The conclusion is simple: recent KOSDAQ weakness was not driven by foreign selling. It was driven by domestic selling pressure overwhelming narrow foreign buying.
3. Why Foreign Buying Was Not Enough
First, foreign buying was concentrated. FADU, EcoPro BM, EO Technics, Hana Micron, Seojin System, Leeno Industrial and SIMMTECH saw strong foreign buying. But much of that was absorption of institutional selling, not broad market accumulation.
Second, breadth broke. KOSDAQ 20-day ADR fell from 120.3 near the April 28 high area to 48.1 on June 2. That means decliners significantly outnumbered advancers.
Third, institutional real money has not returned. KOSDAQ headline institutional buying looks positive YTD, but most of it came from financial-investment accounts.
| YTD KOSDAQ institutional detail | Net buying |
|---|---|
| Financial investment | +116,602 |
| Investment trusts | -4,359 |
| Private funds | -15,017 |
| Pension funds | -4,764 |
| Insurance | -3,234 |
The money that normally sustains KOSDAQ rallies is investment trusts, private funds and part of pension money. That money is still selling.
4. The Important List: Foreign + Institutional Co-Buying
The most useful list is not foreign net-buying alone. It is the names bought by both foreigners and institutions after the April high.
| Rank | Name | Foreigners | Institutions | Combined | Individuals | Return |
|---|---|---|---|---|---|---|
| 1 | SIMMTECH | +1,060 | +408 | +1,469 | -1,465 | +20.7% |
| 2 | Sungho Electronics | +523 | +790 | +1,313 | -1,324 | +14.5% |
| 3 | D&D Pharmatech | +385 | +702 | +1,087 | -1,014 | +6.9% |
| 4 | INTEKPLUS | +64 | +601 | +665 | -619 | +29.7% |
| 5 | AJU IB Investment | +552 | +79 | +631 | +212 | -44.8% |
| 6 | Seegene | +472 | +82 | +554 | -569 | +28.4% |
| 7 | TLB | +114 | +340 | +454 | -443 | +19.2% |
| 8 | Gigavis | +230 | +160 | +390 | -390 | +19.1% |
| 14 | ROBOTIS | +12 | +336 | +348 | -308 | +24.0% |
This is the watchlist for a KOSDAQ rebound. But it is still not enough on its own. Price discipline matters, especially for already-hot names.
5. Triggers For A Real KOSDAQ Rebound
| Trigger | First level | Meaning |
|---|---|---|
| KOSDAQ 20D ADR | 60 | Selling pressure stabilizes |
| KOSDAQ 20D ADR | 80 | Institutions can buy second-line names |
| Daily advancer ratio | 55%+ for 2-3 days | Breadth recovery, not a one-day bounce |
| KOSDAQ index | 1,080 | Short-term downtrend softens |
| KOSDAQ index | 1,100 | Better institutional re-entry signal |
| 5D institutional net buying | +KRW 300B+ | Headline flow turn |
| 5D real money | Positive | Real institutional return |
The single most important signal is 5-day net buying by investment trusts + private funds + pension funds turning positive.
Final View
KOSDAQ’s rebound key is not foreign buying. Foreigners are already buying selected KOSDAQ alpha. The missing piece is institutional real money and market breadth.
Before ADR 60, stay selective. After ADR 80, KOSDAQ exposure can broaden. If foreigners keep buying but real money keeps selling and ADR stays below 50, only a few names such as FADU, SIMMTECH and TLB may work while the index remains weak.

- Data: local Kiwoom DB through June 2, 2026.

- Institutional detail tables may differ from headline market-flow aggregates because of aggregation method differences. The note separates market-wide flow from real-money screens.
