KOSDAQ Part III: Who Found KOSDAQ First? Foreign Capital, Institutional Neglect and Korea’s Hidden Multibaggers

GeoMarketSignal Series 02 — KOSDAQ: Pricing Korea’s Next Technology Cycle, Part III

There is a popular idea in the Korean stock market.

When foreign investors begin buying a company aggressively, they must know something.Sometimes that appears to be true. 

Foreign ownership rises.Institutional research coverage expands. The company enters more portfolios. And a stock that was once regarded as an obscure KOSDAQ name gradually becomes part of the mainstream investment universe.

But there is an obvious problem with the story. Foreign investors can be wrong. Institutions can arrive late. Professional investors can buy cyclical peaks just as retail investors can. And a rising foreign-ownership ratio does not automatically mean that a stock is undervalued.

So the interesting question is not if foreign investors are smarter than Korean retail investors, It is what point does a KOSDAQ company become investable to a much larger pool of capital?

Because one of KOSDAQ’s defining characteristics is not simply valuation dispersion. It is attention dispersion. Some companies attract global investors, institutional capital and extensive analyst coverage. Many others remain largely outside that ecosystem.

And the transition between those two states may be one of the most important — and least discussed — stages in the evolution of a successful KOSDAQ company.

KOSDAQ Has an Ownership Problem Before It Has a Foreign-Investor Story

Start with the market as a whole.

Research published by the Korea Capital Market Institute in July 2026 reveals a striking difference between the investor bases of KOSDAQ and KOSPI companies. Using firm-level market data averaged across year-end 2024 and 2025, KCMI found that foreign ownership in KOSDAQ stood at;

0.36% at the 10th percentile

1.92% at the median

9.19% at the 90th percentile

The comparable figures for KOSPI were:

0.75%

4.70%

27.50%

The difference at the upper end is particularly important.

Even a KOSDAQ company at the 90th percentile of foreign ownership had only about one-third the foreign ownership of a KOSPI company at the same point in its distribution.

KCMI’s interpretation is equally important. KOSDAQ companies are concentrated in the lower ranges of foreign ownership, while companies with substantial foreign holdings form a much thinner group.

The institute argues that this may reflect significant differences in information accessibility, liquidity, institutional attention, and foreign-investor attention across individual KOSDAQ companies.

This tells us something very different from the simplistic claim that “foreigners do not like KOSDAQ.”

Foreign capital does invest in KOSDAQ. But it does so very unevenly.

Institutional Capital Is Even More Important

Foreign ownership is only one part of the problem.

Korea’s Financial Services Commission reported in December 2025 that institutional investors accounted for only 4.5% of KOSDAQ transaction value. That was less than one-third of the institutional share in KOSPI trading. The FSC did not treat this as a trivial market characteristic. It identified weak institutional participation as one of KOSDAQ’s structural problems.

This is important because institutions do more than buy shares.

A functioning institutional ecosystem creates research, earnings models, management meetings, industry comparisons, liquidity, governance pressure, and continuous competition over what a company should be worth.

Retail investors also perform price discovery. But the depth and persistence of institutional research can change the information environment surrounding a company.

And KOSDAQ appears to have much less of it.

Korea Is Trying to Change That

The government’s response is unusually explicit.

The FSC announced measures intended to increase participation by major institutions, including the National Pension Service and Government Employees Pension Service.

One proposed change is particularly revealing.

Institutional fund-performance evaluation, which had relied heavily on the KOSPI index, is expected to incorporate KOSDAQ to some degree.

The logic is straightforward.

If a portfolio manager is judged against a benchmark that barely reflects KOSDAQ, there is little structural reason to spend significant resources researching KOSDAQ companies.

Change the benchmark, and the incentive changes.

The government is also attempting to increase research coverage directly.

Five major securities firms announced plans to increase their average KOSDAQ research staff from 4.6 analysts to 9.2.

They also plan to increase average KOSDAQ research-report production from 396 reports to 621.

These are announced plans rather than completed outcomes.

But the policy objective is unmistakable.

Korea is trying to increase the amount of professional capital and professional attention directed toward KOSDAQ.

Why does this matter to investors? Because attention is not merely publicity.

Attention changes the number of investors capable of forming a serious opinion about a company.

The Difference Between Discoverable and Investable

A company can be discoverable long before it is institutionally investable.These are not the same thing.

Imagine a small KOSDAQ semiconductor supplier. An individual investor can buy it immediately. But a large global institution may face a very different set of questions.Is daily liquidity sufficient? Can a meaningful position be accumulated without moving the price? Is the market capitalization large enough? Are financial disclosures available in English? Does the company hold regular investor-relations meetings? Can management communicate credibly with overseas investors? Are earnings predictable enough for an institutional model? Is corporate governance acceptable? Can the position eventually be exited? Does the stock belong to an index or investment benchmark relevant to the fund?

If several answers are no, the stock may remain outside the institution’s practical investment universe regardless of how interesting its technology appears.

This leads to a concept that may be more useful than simply tracking foreign ownership.

The Investability Inflection Point

A company can improve fundamentally before the capital market fully changes its perception. But as certain conditions accumulate, a threshold may eventually be crossed. Technology becomes commercially validated. Revenue becomes visible. Earnings become forecastable. Market capitalization expands. Liquidity improves. Analysts begin covering the company. Disclosures improve. Institutions can finally build a position of meaningful size. Foreign investors can justify devoting research resources to the stock.

At that moment, the company has not merely become a better business. It has become investable to a much larger pool of capital.

This does not guarantee a rerating. But it changes the potential buyer base. 

Part II Already Gave Us the First Half of the Equation

In Part II, we examined companies that moved from promising stories toward genuine business quality.

The common path was:

Technology → Qualification → Customers → Revenue → Margins → Cash Flow

Now add a second path.

Business Quality → Visibility → Liquidity → Research → Institutional Investability

Together they give us a more complete framework.

A company does not necessarily become institutionally attractive merely because its technology improves. The improvement must also become legible to capital markets.

A company may possess an exceptional technology that engineers understand perfectly but investors cannot value confidently. Another company may have ordinary technology but outstanding disclosure, liquidity and IR. The best candidates for institutional rerating are often those where both improve simultaneously:

Business quality rises while capital-market accessibility rises with it.

This Is Why KOSDAQ’s Best Companies Can Be Penalized by the Market’s Reputation

KCMI raises another issue that deserves serious attention. KOSDAQ contains extremely heterogeneous companies. Some are highly innovative and R&D intensive. Others have weak profitability and financial health. Yet they share the same market identity.

KCMI argues that when high-quality innovative companies are insufficiently distinguished from vulnerable companies, the weaknesses of the latter can damage the reputation of KOSDAQ as a whole.

That can create what is effectively a reputational discount. This is an important idea.

Imagine two identical technology companies.

One trades in a market associated with:

strong institutional ownership,

deep analyst coverage,

high governance standards,

and global investor familiarity.

The other trades in a market associated with:

retail speculation,

weak companies,

poor disclosure,

and unpredictable governance.

Even if the businesses are identical, investors may not assign them identical valuations.

Why? Because valuation is not determined only by expected cash flow.

It also reflects confidence in the information, the market structure, the liquidity, the governance, and the probability that other long-term capital will eventually participate.

In that sense, market reputation can become part of the cost of capital.

But Institutional Neglect Does Not Mean Everything Is Cheap

This is where the thesis needs discipline.

It would be very easy to look at low foreign ownership and low institutional participation and conclude KOSDAQ must be undervalued.

That conclusion does not follow. Institutional neglect can produce undervaluation. But it can also produce overvaluation. A market dominated by retail capital and thin professional research can allow legitimate technology companies to remain ignored. But the same environment can also allow narratives to become detached from economic reality.

Attention dispersion therefore works in both directions. Some stocks receive too little scrutiny. Others receive too much enthusiasm and not enough scrutiny. That leads to one of the central conclusions of this series:

Institutional neglect does not guarantee undervaluation. It increases the probability that price and business quality diverge in either direction.

This is why KOSDAQ can simultaneously contain extraordinary bargains and extraordinary bubbles.

They are different outcomes of the same price-discovery problem.

Are Foreign Investors Actually Better at Finding Winners?

The evidence does not justify that conclusion. And we should resist pretending that it does.

Historical foreign-ownership snapshots can show that some mature KOSDAQ quality companies eventually attracted substantial foreign capital, while other emerging companies began with very little.

But that does not tell us who identified the company first. To answer that rigorously, we would need a standardized time series combining foreign ownership, institutional ownership, stock prices, earnings inflection points, analyst coverage, and major commercial milestones for each company.

Anything less risks confusing correlation with foresight. And even then, “foreign investor” is not a single investor. It includes hedge funds, passive funds, long-only institutions, arbitrageurs, sovereign investors, ETFs and individual foreign accounts.

The useful lesson is therefore not:

Follow the foreigners.

It is:

Watch when the investor base begins changing because the company itself has changed.

That is fundamentally different.

Ownership Can Be a Consequence, Not a Cause

Consider a technology company moving through the framework developed in this series.

At first the technology is uncertain, revenue is small, liquidity is poor,and few analysts cover the stock. Foreign ownership is low. Then a major customer qualifies the product. Revenue rises. Margins improve. Market capitalization increases. Liquidity improves. Research coverage begins. Foreign ownership then increases. Did foreign investors cause the company to become better?

No.

In many cases, their arrival may simply confirm that the company has already crossed a threshold of institutional investability. This means foreign ownership can be a lagging indicator of quality recognition, rather than a leading indicator of corporate quality.

But there is another possibility. Sometimes global investors may recognize a structural industry change earlier because they compare companies across countries.

A Korean semiconductor-equipment supplier may look obscure domestically but obvious to an investor already following TSMC, ASML, Applied Materials and global semiconductor capex.

A Korean rechargeable-battery supplier may be easier to understand for an investor simultaneously analyzing Tesla, CATL, Panasonic and European EV policy.

This is where international capital can add something genuinely valuable, a different comparison set.

Not necessarily better intelligence, a different frame.

Local Knowledge and Global Context

KOSDAQ therefore creates an unusual information contest.

Domestic investors often possess better local information.

They may understand management reputation, local supply chains, hiring activity, factory expansions and customer relationships much earlier.

Foreign investors may possess a broader global comparison framework.

They may understand where a Korean company sits relative to:

international competitors,

global capex cycles,

global customer demand,

and international valuation benchmarks.

Neither side automatically has superior information.

Their information is different.

And the biggest opportunity may emerge when local knowledge and global structural change point in the same direction.

That is precisely the type of gap GeoMarketSignal is interested in.

Research Coverage Can Matter More Than Investors Realize

Consider what happens when a previously under-covered company receives serious institutional research.

An analyst begins modeling revenue.

The company is compared with global peers.

Management receives more sophisticated questions.

Consensus expectations begin forming.

Institutional investors can quantify downside risk.

Earnings surprises become measurable.

Corporate guidance becomes more important.

The company effectively enters a different information regime.

This can improve price discovery.

It can also make the stock less forgiving.

A company supported primarily by narrative can survive vague expectations.

Once institutions build detailed models, numbers matter more.

That is why greater institutional participation should not simply be interpreted as bullish.

It may increase the rewards for quality.

It may also increase the punishment for companies that fail to deliver.

In the long run, that could be exactly what KOSDAQ needs.

The Potential Rerating Mechanism

Put the pieces together and a possible KOSDAQ rerating mechanism begins to emerge.

Not:

Government supports KOSDAQ → KOSDAQ goes up.

That is far too simplistic.

The mechanism would be more like this:

Stricter delisting
→ weaker companies exit faster

Better technology-listing expertise
→ stronger innovative companies enter

Improved research coverage
→ information gaps shrink

More institutional participation
→ professional price discovery deepens

Better disclosure and governance
→ investability improves

High-quality KOSDAQ companies become easier to distinguish
→ the market-wide reputational penalty may decline

That would not raise the valuation of every company. A better market is not a market where every stock becomes expensive. A better market is one where good companies and bad companies are priced more differently.

That is the more interesting reform thesis.

The Hidden Multibagger May Already Be Visible

There is a final irony.

Investors often imagine that the next multibagger must be completely undiscovered. Its technology may already be public. Its major customers may already be known. Its factories may already exist. Its revenue may already be accelerating.

The problem is that these facts have not yet combined into an institutional investment case.

This is where Part II and Part III meet.

Part II showed that great KOSDAQ companies move from:

story → validation → scale → quality

Part III adds:

quality → visibility → investability

The most interesting point may be the overlap.

A company can become a better business before it becomes a better-known investment.

The gap between those two moments may be one of KOSDAQ’s most interesting sources of mispricing.

So Who Found KOSDAQ First?

There is no single answer.

Sometimes retail investors arrive first. Sometimes foreign investors recognize a global industry connection early. Sometimes institutions wait for earnings visibility. Sometimes everyone sees the story and everyone misprices it.

The more useful conclusion is this:

The investor who arrives first matters less than the moment when the company becomes investable to everyone else.

That transition can dramatically expand the potential capital base. But it only creates lasting shareholder value if the underlying business deserves the attention. Which brings us to the final part of this series.

We have now established three things.

Part I showed that KOSDAQ cannot be understood through a single valuation multiple.

Part II showed that its greatest winners justified premium valuations by becoming substantially better businesses.

Part III shows that better businesses can eventually become accessible to a much larger institutional and global investor base.

The final question is therefore obvious.

Where is that transition most likely to happen next?

Next in Series 02

Part IV — The Next KOSDAQ: Where Korea’s Technology Pipeline Meets Global Capital

We will apply the framework to the industries shaping Korea’s next technology cycle:

AI Semiconductors

Rechargeable Batteries & ESS

Robotics & Industrial Automation

AI Power, Nuclear & SMR

Biotechnology & Aerospace

with a shorter look at Cosmetics and Entertainment.

The goal will not be to identify fashionable industries.

It will be to identify where technology, commercial validation, cash-flow potential and institutional investability may be converging.
