While KOSPI breached 7,500 and printed an all-time market-cap high, KOSDAQ has been oscillating around the 1,200 line. YTD 2026 the small-cap board is +30% — not bad in absolute terms, ahead of Turkey, Japan, and Brazil — but less than half of KOSPI’s +75%. The retail-investor complaint is by now familiar: “KOSDAQ doesn’t go up when KOSPI goes up, and goes down when KOSPI goes down.” Underneath the relative-performance frustration, however, the structural change worth tracking has finally surfaced: a promotion-relegation system that splits all ~1,820 KOSDAQ-listed companies into Premium (Tier 1, ≤100 names), Standard (Tier 2), and Watch (Tier 3) segments, with movement between tiers based on earnings and governance. The reform launches as early as October 2026. The point is not to publish another curated list — the 2022 KOSDAQ Global Index already proved the curation worked but the money didn’t follow. This time the design must build the buy-side plumbing too.

TL;DR

What KOSDAQ is. Korea’s growth-equity board, launched in 1996 as a NASDAQ analog. ~1,820 listed companies. Dominated by biotech, semiconductor equipment, gaming, beauty, robotics, battery-materials. The “next-generation Samsung Electronics” tends to start its public-market life here.
Up +30% YTD but overshadowed. That print beats Turkey (+29%), Japan (+18%), Brazil (+16%). But against KOSPI +75%, it reads as relative underperformance — KOSPI’s rally was that large, not because KOSDAQ collapsed.
A 25-year breakout. April 24, 2026 closed at 1,203.84 — the first close above 1,200 since the dot-com peak in March 2000. Driven by breadth (semiconductor-equipment, biotech, robotics, batteries) rather than a single-theme rip.
The reform that matters: October 2026 promotion-relegation. All ~1,820 listed names get split into Premium (≤100), Standard, and Watch. Earnings-based promotion and relegation. The intent: build the institutional plumbing (premium-segment ETFs, NPS benchmark inclusion, ₩6tn People’s Growth Fund) so passive and pension capital have forced exposure to the curated top tier rather than optional.
The legacy problem the reform is trying to fix. KOSDAQ’s index-level top names skew toward names with elevated multiples and unproven earnings — Ecopro BM at PER ~596×, LegoChem Bio at ~286×, Robotis at ~390×, ABL Bio loss-making but at #9 by market cap. A KOSDAQ150 mechanically tilted toward unprofitable names is exactly the kind of benchmark institutions cannot underwrite.
Premium-segment success requires actual buy demand, not just the list. The 2022 KOSDAQ Global Index returned +160% vs. KOSDAQ broad +65% — proving curation works. But it never became a pension benchmark or an ETF magnet. The October reform must avoid that trap.
Why this matters at the name level. Stocks already covered in our prior posts that sit on KOSDAQ — ISU Petasys (substrate stack), OE Solutions (CPO), APR (beauty), Easy Bio (feed-additive platform) — see different forward valuations depending on Premium-tier inclusion. Inclusion = passive flow + NPS attention + liquidity uplift. Exclusion = retail-flow status quo.

1. What KOSDAQ Is — for foreign investors arriving fresh

1.1 Korea’s “second exchange”

Item	KOSPI	KOSDAQ
Character	Large-cap, blue-chip	Growth, innovation
Launched	1956	1996
Listed companies	~950	~1,820
Market cap	~₩6,000tn (8th globally)	~₩673tn
Sector tilt	Semis, autos, financials, energy, shipbuilding	Biotech, semi-equipment, gaming, beauty, robotics
Investor base	Foreign / institutional dominant	Retail dominant (64% of trading volume)
Volatility	Lower	Higher
Index base	1980-01-04 = 100	1996-07-01 = 1,000
Flagship index	KOSPI 200	KOSDAQ 150

KOSPI is the home of Samsung Electronics, SK hynix, Hyundai Motor. KOSDAQ is where the next generation lives. Mapped to the U.S., KOSPI ≈ NYSE and KOSDAQ ≈ NASDAQ.

1.2 The name and the original mission

KOSDAQ stands for Korea Securities Dealers Automated Quotation — a deliberate echo of NASDAQ. The launch mandate was to give SMEs, ventures, and tech companies an equity-funding path that KOSPI’s stricter listing thresholds wouldn’t allow. The Financial Services Commission still describes KOSDAQ as “the core infrastructure of Korea’s innovation and venture ecosystem.”

1.3 KOSDAQ vs. NASDAQ — where they diverge

Item	U.S. NASDAQ	Korea KOSDAQ
Market cap	~$29tn (#1 globally)	~₩673tn (~$500bn)
Flagship names	Apple, Nvidia, Microsoft	Alteogen, Ecopro BM, HLB, Leeno Industrial
Institutional weight	High	Low (retail = 64% volume)
Hosts mega-caps?	Yes (Apple ~$4tn cap)	No (large-caps migrate to KOSPI)
Market perception	“World’s leading tech-stock board”	“Volatile, sometimes speculative”

The single most important divergence: NASDAQ keeps Apple and Nvidia. KOSDAQ loses its winners to KOSPI. 54 companies have transferred from KOSDAQ to KOSPI since launch; the 48 still listed today have a combined market cap of ~₩218tn — more than 30% of KOSDAQ’s entire market cap. The structural weakness is built in: the best-performing companies leave the board. Closing this leak is one of the explicit goals of the October promotion-relegation reform.

2. KOSDAQ’s 30 years — boom, collapse, and a 25-year recovery

2.1 Compressed history

1996.07: Launched at 1,000
1997-1998: Asian financial crisis collapse
2000.03: 2,834 ← all-time high (dot-com peak; not yet broken)
2000.12: 525 ← bubble burst, -80%
2001-2019: Range-bound 400-900 — the "lost two decades"
2020: COVID-low rebound, retail-investor onboarding wave
2022-2024: Rate hikes, capital-gains-tax debate, drift back to 600-800
2025 H2: Government KOSDAQ-revitalization program
2026.01.26: Reclaims 1,000
2026.04.24: Closes at 1,203.84 → first 1,200+ close in 25 years
2026.05: Oscillating around 1,200

2.2 Why the 25-year breakout matters

KOSDAQ has approached 1,200 multiple times and failed each time. The April 2026 break is different because the move was driven by breadth — semiconductor materials/equipment, biotech, robotics, and batteries simultaneously — rather than a single thematic rip.

The relative gap to KOSPI is real and hurts perception. On May 6, KOSPI surged +447 points (+6.5%) and broke 7,000 — KOSDAQ closed -0.3% the same session. “Doesn’t rally with KOSPI, sells off with KOSPI” is the retail complaint that crystallized.

But KOSDAQ +30% YTD is genuinely not bad in absolute terms — it’s ahead of Turkey (+29%), Japan (+18%), Brazil (+16%). The relative softness is a function of KOSPI’s outsized rally, not KOSDAQ deterioration. Why Korea Part 4 covers the $6.7bn foreign ETF inflow that overwhelmingly went to Samsung Electronics and SK hynix — i.e., to KOSPI, not to KOSDAQ. The October reform is one of the explicit channels for redirecting that capital.

3. What’s actually inside KOSDAQ — by sector

3.1 Biotech / pharma — the biggest segment

Most of KOSDAQ’s index-cap top sits in biotech. Korea has begun building real strength in biosimilars, antibody-drug conjugates (ADCs), and cell-and-gene therapy.

Alteogen — subcutaneous-injection drug-delivery platform, licensed to global pharma. Among the largest names in KOSDAQ by market cap.
LegoChem Biosciences — ADC platform with multiple large licensing deals.
ABL Bio — bispecific antibodies. ~#9 by market cap despite a projected ₩48.6bn loss this year.
Kolon TissueGene — gene therapy for osteoarthritis.

The sector is KOSDAQ’s biggest strength and its biggest volatility source. Names move +100% on trial reads and -50% on accounting issues. SamCheonDang Pharmaceutical hit #1 in KOSDAQ market cap at a ₩1.23m share price in March 2026, then collapsed below ₩400k after disclosure-failure designations — a textbook KOSDAQ episode.

3.2 Semiconductor equipment / materials — the AI second derivative

If KOSPI hosts Samsung Electronics and SK hynix, KOSDAQ hosts most of their suppliers.

Jusung Engineering — semiconductor and display deposition equipment.
Wonik IPS — wafer-process equipment.
Leeno Industrial — test sockets and probe pins, leading global market share.
Hanmi Semiconductor — back-end equipment with HBM exposure (a key 2025-2026 AI beneficiary).
ISU Petasys — high-layer-count PCBs for AI servers and switches. Covered in Korea AI PCB Ecosystem: 10 Companies.
OE Solutions — optical transceivers and laser chips, with CPO-related external-light-source products. Covered in Korea Optical / CPO Value Chain — 7 Companies.

This is the segment doing most of the heavy lifting in 2026’s KOSDAQ rally.

3.3 Gaming, beauty, robotics, batteries — the cluster names

Gaming: Pearl Abyss (Black Desert / Crimson Desert global MMORPGs), Wemade, Com2uS, Kakao Games.
Beauty: Classys (medical aesthetics devices, HIFU), PharmaResearch (Rejuran PN skin booster, polynucleotide platform), Silicon2 (global K-beauty distribution platform), Englewood Lab (US-market beauty ODM). See Why Korea Part 2 — Korean Cosmetics for the ecosystem context. Note: APR (KOSPI 278470) and Cosmax (KOSPI 192820) — both well-known Korean beauty names — are KOSPI-listed and outside the scope of this KOSDAQ guide.
Robotics: Rainbow Robotics (bipedal humanoid with Samsung Electronics as strategic investor).
Battery materials: Ecopro BM (cathodes, near top of KOSDAQ market cap, projected PER ~596×).

4. Why KOSDAQ has carried a “casino-board” reputation

4.1 Top-of-cap names with unverified earnings

The Maeil Business Newspaper framing is sharp: KOSDAQ’s highest-market-cap tier is dominated by names with elevated multiples and unproven earnings.

Name	Market cap	2026E net income	Implied PER
Ecopro BM	₩23tn+	Tens of ₩bn	~596×
LegoChem Bio	₩7tn+	~₩40bn	~286×
Robotis	₩5tn	~₩10bn	~390×
ABL Bio	#9 by market cap	-₩48.6bn (loss)	n/m

High multiples on growth names are not, in themselves, a problem — NASDAQ also hosts loss-making names at the cap top. The actual issue is structural: when index methodology elevates unverified-earnings names into KOSDAQ 150, the benchmark itself becomes uninvestable for institutions whose mandates require profitability filters.

4.2 The KOSDAQ 150 design problem

KOSDAQ 150 selects on free-float market cap and trading volume. Under that filter, unprofitable thematic names (battery-materials, biotech, robotics) with inflated caps from expectation alone end up in the index ahead of profitable mid-caps with stable earnings. Pension funds running KOSDAQ 150 as a benchmark are then forced to underwrite that mix. They mostly choose not to.

4.3 The good companies leave for KOSPI

KOSDAQ’s most-successful graduates transfer up to KOSPI to access deeper institutional and foreign liquidity, plus larger passive pools. 54 companies have made that move; the 48 still listed today carry ~₩218tn of market cap — over 30% of KOSDAQ’s total. The board’s structural weakness is that its winners exit.

5. The October Reform — a 3-tier league with promotion and relegation

5.1 What changes

From October 2026 (or as soon as feasible), KOSDAQ’s ~1,820 listed companies get sorted into three tiers:

Premium (Tier 1):
- ≤100 companies
- Selection on financial soundness, growth, governance
- Designed as the destination for pension and passive flows
- New dedicated index + ETF products

Standard (Tier 2):
- Mid- and small-caps below the Premium threshold
- Separate index and ETF products under consideration
- Provides depth, mitigates Premium-only flow concentration

Watch (Tier 3):
- Distressed / problem names
- Accelerated delisting pathway

The promotion-relegation logic is direct: companies move between tiers based on earnings and governance metrics. Same idea as football-league relegation, applied to capital markets.

5.2 Why this matters — “a good list” ≠ “a list institutions must own”

A market-participant quote captures the design lesson:

“We made a list of good companies, but we never built a structure that forces investors to actually own them.”

That refers to the 2022 KOSDAQ Global Index: ~50 selected names, +160% return since launch (vs. KOSDAQ broad +65% same period). The curation worked. The flow didn’t. ETFs tracking the Global Index stayed small. NPS never adopted it as a core benchmark. The October reform’s design intent is to fix that — move beyond curation and build the institutional flow architecture into the system itself.

5.3 Specifically, what flow channels open

1. Premium-index passive flow. A dedicated Premium index becomes the underlying for new ETFs. Passive AUM mechanically buys the Premium 100 — separate from existing KOSDAQ 150 passive demand.

2. NPS benchmark inclusion. If the National Pension Service’s domestic-equity benchmark begins to assign weight to KOSDAQ (per reform discussions, ~5%), then funds and external managers ignoring KOSDAQ underperform their benchmark. “Not buying” becomes a relative-performance penalty rather than a neutral choice.

3. People’s Growth Fund. A ₩150tn (5-year) People’s Growth Fund is being aligned with KOSDAQ. Of the ₩30tn scheduled this year, ₩10tn flows into equity / indirect investment, including special-listing tech companies and pre-listing KOSDAQ pipeline. The ₩600bn People’s Participating subfund launching May 22 carries a minimum 10% (₩60bn) allocation requirement to KOSDAQ tech-special-listing names.

5.4 The “stop the leak to KOSPI” effect

If Premium-tier names can access pension money and passive flows while staying on KOSDAQ, the incentive to transfer up to KOSPI weakens. The structural leak that has cost KOSDAQ its winners for 25 years could finally be plugged.

5.5 Timeline

Now: Korea Capital Market Institute (KCMI) finalizing detail design
June: Market-participant briefings, public comment
July: KOSDAQ 30th-anniversary event — formal disclosure of the reform framework
October (target): Reform goes live

6. The ratio that matters — 50 well-chosen names vs. the broad index

6.1 What the KOSDAQ Global Index already proved

KOSDAQ Global Index (\~50 quality names):
2022.11.21 inception (1,000) → 2026.05.08 (2,602) → +160.2%

Same period:
KOSDAQ broad (\~1,800 names): +65%
KOSDAQ 150 (150 names): +93%
KOSDAQ Global (\~50 names): +160%

The selection-method matters more than KOSDAQ-the-asset-class. Choosing 50 well-screened names returned ~2.5× the broad index. “KOSDAQ doesn’t work” is the wrong framing. “Which KOSDAQ names you own” is the question.

6.2 Premium selection must be earnings-based, not just cap-based

The legacy KOSDAQ 150 was effectively cap-and-volume. That filter inevitably promoted unverified-earnings names — Ecopro BM at PER ~596×, ABL Bio loss-making, Robotis at PER ~390×. The Premium-tier brief explicitly cites financial soundness and growth as the selection criteria. If the implementation actually screens out cap-only names, the resulting benchmark is institutionally underwriteable in a way KOSDAQ 150 has never been.

7. Why this matters for the names we already cover

7.1 KOSDAQ-listed names from our prior posts

ISU Petasys — covered in Korea AI PCB Ecosystem: 10 Companies.
OE Solutions — covered in Korea Optical / CPO Value Chain — 7 Companies.
Easy Bio — covered in Part 1 and Part 2.
Silicon2 / Pamicell — covered in the ROE-25% screen.

For each of these, Premium-tier inclusion is a non-trivial valuation variable.

If included:

Mechanical passive-fund inflow via Premium-index ETFs
NPS-benchmark consideration
Liquidity-tier improvement
Multiple-rerating optionality on the back of cleaner buy-side access

If not included:

Retail-flow regime continues
Institutional access remains gated

7.2 The variables to track from October

The Premium 100 list itself — earnings-based or cap-based? The single most important reveal.
ETF launch pace and AUM — does Premium-index passive AUM reach a meaningful scale?
NPS benchmark adoption — does KOSDAQ actually enter the pension benchmark?
People’s Growth Fund deployment — does the ₩600bn participating subfund meaningfully invest in KOSDAQ tech names?
KOSPI transfer activity — do Premium-tier names stop migrating up to KOSPI?

8. Risks that could neutralize the reform

8.1 “List changes, money doesn’t”

The 2022 KOSDAQ Global Index outcome could repeat. Premium list curated, ETFs launched, but AUM stays small and NPS doesn’t adopt it as a benchmark. Without the institutional pull, capital-flow patterns don’t shift.

8.2 Thematic volatility persists

The reform doesn’t lower KOSDAQ volatility per se. Among the ~1,720 non-Premium names, retail-driven theme rallies and crashes will continue. The “KOSDAQ is risky” perception doesn’t dissolve overnight.

8.3 Diluted Premium criteria

If the Premium tier ends up including loss-making or unverified-earnings names — to satisfy lobbying or political optics — the credibility premise collapses. The criterion has to be earnings, not market cap. Anything else recreates the KOSDAQ 150 problem under a new name.

9. Bottom line

KOSDAQ is a 30-year-old market that still hasn’t recovered its 2,834 dot-com peak. Twenty-five years of “lost market” status. YTD 2026 is +30% with a 1,200 breakout — but KOSPI’s +75% has overshadowed the move and produced more retail frustration than appreciation.

The structural change worth tracking is the October promotion-relegation reform. Splitting ~1,820 listed names into Premium (≤100), Standard, and Watch, with movement based on earnings, is one piece. The piece that matters more is building the institutional plumbing — Premium-index ETFs, NPS-benchmark inclusion, People’s Growth Fund alignment — that forces real flow into the new top tier. If those three pieces work, KOSDAQ-quality names see liquidity and multiple uplift.

The KOSDAQ Global Index already proved the upper bound: 50 well-chosen names returned +160% while the broad index returned +65%. “KOSDAQ doesn’t work” was always the wrong framing. “Which 50 names” was the question. The October reform’s success or failure compresses to two design choices — does the Premium screen prioritize earnings over cap, and does the institutional plumbing actually pull flow.

FAQ

Q: How does KOSDAQ differ from KOSPI for foreign investors? A: KOSPI is large-cap blue-chip (Samsung Electronics, SK hynix, Hyundai Motor, ~950 names); KOSDAQ is growth (biotech, semi-equipment, gaming, robotics, ~1,820 names). U.S. analog: NYSE vs. NASDAQ. KOSDAQ is more volatile and far more retail-dominated.

Q: Who is the largest company on KOSDAQ? A: It rotates frequently. Recently Alteogen, Ecopro BM, HLB, and Leeno Industrial have traded near the top. Because KOSDAQ’s biggest winners migrate to KOSPI (54 names historically — APR and Cosmax are recent examples), KOSDAQ’s “leader” is structurally a newer cohort rather than a stable Apple-equivalent.

Q: Why has KOSDAQ underperformed KOSPI in 2026? A: The $6.7bn YTD foreign ETF flow concentrated in KOSPI mega-caps (Samsung Electronics, SK hynix). KOSDAQ is retail-dominated and pension/foreign access is structurally limited. The October promotion-relegation reform is the explicit attempt to redirect institutional flow into KOSDAQ Premium-tier names.

Q: What does the promotion-relegation system actually do? A: It splits ~1,820 KOSDAQ names into Premium (≤100), Standard, and Watch, with movement between tiers tied to earnings. Combined with new Premium-index ETFs, NPS-benchmark inclusion, and the People’s Growth Fund, the design forces pension and passive capital into the curated top tier. The intent is to break the 25-year leak of KOSDAQ winners to KOSPI.

Q: Which KOSDAQ stocks should I watch around the October reform? A: Focus on profitable mid-caps with sustainable margins — Leeno Industrial, Hanmi Semiconductor, Classys, PharmaResearch, Easy Bio, etc. — that could plausibly meet earnings-based Premium criteria. The list itself is finalized only after October; pre-positioning carries category risk.

Q: What’s the biggest risk that the reform fails? A: The 2022 KOSDAQ Global Index outcome repeating — the Premium list gets curated, ETFs launch but stay small, NPS doesn’t adopt it as a benchmark. Without the buy-side plumbing actually engaging, the new list won’t change flow patterns.

Q: Which KOSDAQ stocks see the largest foreign-investor presence today? A: Names with high foreign-ownership ratios include Alteogen, Leeno Industrial, and HLB. Mostly companies with high overseas-revenue mix, or biotech names with advanced clinical pipelines.
