What You Actually Own When You Own a Share — And Where You Stand in Line

The People Who Bought Slices

Starting in 2021, one tax-advantaged account in South Korea allowed people to directly buy slices of domestic companies. This account groups various financial products together in one place and gives tax benefits on the net profit left after subtracting losses from gains. The account itself first appeared in 2016, and the branch for buying company slices directly was added in 2021 (DOI: 10.35850/KJTR.42.3.01).

Ever since, individuals holding small, fractional pieces of companies have grown by an amount that is hard to dismiss as a coincidence. The growth was larger in stable companies that have been open for a long time or pay out a large share of their earnings than in fast-growing companies (DOI: 10.35850/KJTR.42.3.01 · Data on domestic firms listed on the exchange from 2011 to 2023). The authors suggest that the account's conditions—which require holding it for several years and cap the tax-free amount—may have fostered a tendency to hold slices for a long time. They also write that the diversification of people holding slices helped raise the companies' worth.

So, what does holding that slice actually mean you possess? This글 asks two questions. What comes with holding that slice? And when money coming into a company is split, what number am I in line?

This article is written focusing on companies whose slices are listed on the South Korean exchange. The systems appearing later are also Korean ones. However, since there are studies that looked at companies outside South Korea or whose abstracts do not specify the sample's country, those studies are noted on the spot. And we do not discuss prices for any company or at any point in time. We write only about what the mechanisms look like and what the research measured.

Breaking the Company into Pieces

Let us imagine a company is divided into 100 pieces. If you hold 10 of them, your share is one-tenth; if you hold 1 piece, it is one-hundredth.

One of those tiny slices into which the company is chopped up into equal sizes is a stock. All 100 pieces added together make up the entire company. A person who holds those pieces is called a shareholder. The person holding 10 pieces and the person holding 1 piece are both shareholders, and the only difference is the size of their share.

Putting the company's pieces on an exchange so that anyone can buy and sell them is what we call listing. In Korea, the KOSPI and KOSDAQ markets are those exchanges. Once listed, the pieces change hands among people who previously had no relation to the company.

When the pieces are scattered like that, the side that owns the company and the side that runs it become separated. If 100 people each held one of the 100 pieces, those 100 people could not gather every day to run the company. Therefore, the job of running it is entrusted to the management. This is the common picture used to explain a listed company. Ownership is scattered among small shareholders, and thus ownership and management are separated (DOI: 10.1093/0198288816.001.0001 · an English theoretical textbook not specifying a country).

Two Things That Come Attached to a Slice

Two things come attached to a single slice: a voice in how the company is run, and a share of the money left over in the company, proportional to the size of the slice (DOI: 10.1017/s0022109000002519 · the quality noted at the beginning of a paper discussing worker share ownership).

The right to cast a ballot on important decisions made by the company is called voting power. The standard form is one vote attached to one slice, so a person holding 10 slices wields 10 votes.

The share side is best viewed as standing in a line. There are people in a company whose amounts to receive are fixed in advance. They are the suppliers, the workers, and the lenders. The amounts they are to receive are written down in contracts, while shareholders have no such numbers.

The right to whatever is left over after the side whose shares are fixed by contract takes everything—this is called the residual claim.

Moving this to a shop, it looks like this. If 10 million won came in this month and 9 million won went out for material costs, rent, and staff salaries, what remains in the owner's hand is 1 million won. Even if the incoming money drops to 9.5 million won, the 900万 won that must go out stays the same. Therefore, the owner's share shrinks to 500,000 won, and if the incoming money is 9 million won, the owner's share is 0. Conversely, even if 11 million won comes in, the money that must go out is still 9 million won, so the owner's share doubles to 2 million won.

Shareholders stand at the very back of this line. The side with written amounts gets paid first, and shareholders receive what is left after that. The fact that a shareholder's share swells greatly when what is left is large, and that nothing is received when there is nothing left, come from the exact same single nature.

Sometimes one person stands in two spots of this line at once. This is when a worker employed by a company holds slices of that company. The worker wields both a contracted share called a salary and a share of what is left over. Then the direction in which they use their vote can also change.

Publicly traded companies governed by workers have deviated further from value maximization—in other words, the path that makes the company's worth as large as possible—than other companies. They invested less in long-term assets and took on fewer risks. They grew more slowly, created fewer new jobs, and had lower productivity (DOI: 10.1017/s0022109000002519 · a study in an English-language academic journal; the abstract does not disclose the country of the sample). The authors propose that workers use their voice to grow the combined value of their salary and their residual share. Because of that, company policies often drift away from maximizing shareholder value.

The share granted by a slice is the remainder received at the end of the line, and its size is not written down in advance.

Until What Remains Reaches the Shareholders' Hands

Let us imagine a company made up of 100 slices finishing a year. Money comes in, and the cost of materials, salaries, and interest on borrowed money are paid out first, leaving what remains. That remainder has not yet gone into the shareholders' wallets. It can be kept right in the company safe, or shared among the people who hold the slices.

Sharing a portion of what the company earned among the shareholders according to the number of slices they hold is called a dividend. If the company decides to share 1,000 won per slice, a person holding 10 slices receives 10,000 won, and a person holding 1 slice receives 1,000 won. What goes to the person holding 1 slice is 1/100 of the total money decided to be shared.

Regarding whether to keep the money in the safe or share it, the interests of those running the company and those owning it can clash. The problem that arises when the interests of those entrusted with running the company and those who own the company diverge is called the agency problem. The more money managers hold in their hands, the greater their power grows, and so they have the incentive to grow the company beyond its appropriate size (DOI: 10.1017/cbo9780511609435.005 · an English book chapter summarizing the theory).

In this theory, dividends act to pare down that power. When cash goes out to shareholders, the money the managers can tinker with decreases, and the managers' power diminishes by that much. Also, when the company needs new money, if there is no money piled up inside, it must seek it from the outside, and the possibility of being monitored by those supplying the money at that time increases (DOI: 10.1017/cbo9780511609435.005).

We can count backward to see how much would have remained in the hands of management if dividends had not been paid. This is a calculation imagining that in 2002, the 25 largest corporations that had long paid dividends did not pay them. If so, the cash they would have held would have swelled from 160 billion dollars (6% of total assets) to 1.8 trillion dollars (51% of total assets) (DOI: 10.3386/w10599, NBER working paper · hypothetical calculation of 25 companies, the abstract does not specify the country). This means that more than half of what they owned would have piled up as cash. The authors view that if so, management would have held an additional 1.6 trillion dollars in their hands without better investment opportunities or additional monitoring.

In the same working paper, companies that had earned and piled up a larger share over time were more likely to pay dividends. To be precise, it was the ratio of the earned and piled-up portion among the shareholders' share on the books, and this relationship was statistically significant, meaning it was difficult to see it as mere coincidence. The authors read this as a result consistent with the hypothesis that companies pay dividends to alleviate the problem of money piling up in management's hands.

Whether to share or not is newly decided each year and is shaken by external circumstances. The harder it is to gauge how the government's economic policies will unfold in the future, the more the likelihood of reducing dividends significantly decreased and the ratio of holding cash significantly increased (DOI: 10.22510/kjofm.2026.43.4.005 · listed companies in South Korea's KOSPI and KOSDAQ markets from 2016 to 2025, with 18,820 cases counting one year of a single company as one case). The authors interpret that when things are uncertain, companies adjust whether or not to pay dividends before adjusting the dividend amount itself. They view this as holding onto cash in preparation for when it becomes difficult to secure money in the future.

This effect appeared overall regardless of whether a company had a hard time securing money or not. However, evidence saying the effect was consistently stronger in such companies was limited. The authors write that when discussing policies to increase dividends, two things must be considered together: the company's leeway to circulate money, namely financial flexibility, and how far ahead the policy can be seen.

Dividends also differed depending on who held the slices. In domestic insurance companies, the larger the share of the shareholders holding the most slices and the share of foreigners, the significantly higher the dividend indicators, such as the ratio of what is shared among earnings, were. Between the two relationships, the foreign side was clearer (DOI: 10.17342/KIJ.2024.138.5 · sample of domestic insurance companies). The authors read this as meaning that shareholders' power to demand dividends actually affects dividends. That the foreign side is clearer is read as meaning that the influence of institutional investors, who gather other people's money and run it on their behalf, is becoming important in the insurance industry as well. In the same study, how trustworthy the books are—that is, the quality of accounting information—also affected dividends, but statistical significance was not high.

Whether to share what remains at the end of the line is newly decided each year. In domestic insurance companies, the sharing ratio also moved together with who held the slices.

What a Single Table Can Do

It is the day a company made of 100 pieces is electing three new directors. A shareholders' meeting is where shareholders gather to decide important company matters through a vote. One shareholder holds 60 pieces, and the remaining 40 pieces are divided among several people.

If you hold a separate vote for each director seat, all three seats go 60 to 40 according to the wishes of the large shareholder. A shareholder with a small stake—not enough to sway the company—is called a minority shareholder. They can cast a vote, but that single vote rarely changes the outcome.

Changing the way votes are counted changes the result. When electing multiple directors at once, a system where you give as many votes per piece as there are directors to elect, and allow those votes to be pooled for a single candidate, is called cumulative voting. If you elect three directors, one piece gets three votes. The 40 small pieces can combine their intentions to pool 120 votes for a single candidate. For the large shareholder to defeat that candidate, they must give each of their three candidates more than 120 votes. However, the large shareholder has 180 votes, so only one candidate can be given that many. Therefore, in a company using this system, one of the three seats goes to the candidate gathered by the small stakes. Whether to use this system is decided by the company.

As important as the voting method is the venue where votes are cast, and that venue itself is evaluated as weak. A paper comparing listed company shareholders' meetings with systems in other countries considers that shareholders' meetings have failed to exercise the authority granted by law and have been hollowed out. It also suggests that part of the cause may lie in procedures, such as when and how they gather, and the rules by which meetings are run (KCI ART002075550, a comparative law review paper). The author asks whether a shareholders' meeting must necessarily be a meeting gathered in one place, and suggests discussing institutional improvements by letting go of that premise.

Korea has revised its system several times to protect shareholders with small stakes. The main goals of the 1998–1999 financial reforms were to protect minority shareholders and raise corporate transparency to make the inside of companies more visible from the outside. Looking at companies that stopped and then resumed paying dividends, a relationship appeared significantly where enterprises with good earnings and a large amount of retained earnings after the reform were more likely to resume dividends. That relationship did not exist before the reform (DOI: 10.18032/kaaba.2017.30.2.161). The authors' interpretation is that once the law took the side of shareholders, it became possible for shareholders to extract cash from companies with a high likelihood of wasting money. The authors conclude that strengthening legal protection for shareholders clearly had a positive effect on dividend payouts.

Devices that directly magnify the votes of small stakes include the cumulative voting system seen earlier and the voting-by-mail system. Allowing votes to be cast by mail without attending the shareholders' meeting in person is called voting by mail. Both systems are rights-protection institutions that strengthen the voting rights of minority shareholders by allowing their opinions to be reflected more in director elections and shareholders' meetings (KCI ART001923662). Enterprises that introduced the two systems paid more dividends than enterprises that did not, and their company value, meaning corporate value, was also higher. Comparing the same enterprises before and after adoption, it was higher after adoption (KCI ART001923662).

The authors read that performance improved because this system reduced company money that controlling shareholders could misappropriate for private use, meaning cash flow subject to private diversion. The authors noted at the time the paper was released in 2014 that this system was in a state of "drifting due to large corporations," and wrote that their results could serve as grounds for making this system mandatory.

When a shareholder directly submits an agenda item to a shareholders' meeting, it is called a shareholder proposal. After shareholder proposals were submitted, companies' governance ratings—meaning ratings evaluating how a company is run and monitored—improved. The improvement was more pronounced after the introduction of guidelines encouraging institutional investors to exercise their votes diligently. However, shareholder proposals had no notable impact on corporate value (DOI: 10.26845/KJFS.2023.6.52.3.421 · 474 shareholder proposals submitted to shareholders' meetings from 2010 to 2021). Corporate value here was measured by stock price movements around the voting date. However, after the guidelines were introduced, the stock price change stripping away normal movements during the two days before and after the voting date became significantly larger than before the introduction.

Whether strengthening shareholders' votes is always right is a question that can be debated separately. In the United States, debates have continued over how much control shareholders should hold. A comparative law paper reviewing shareholder rights in U.S. corporate law notes this premise as a starting point: actual management is normally done by the board of directors, and shareholders do not know internal company information nor do they possess experience or qualifications as managers (DOI: 10.35227/HYLR.2025.5.36.2.161). The U.S. has basically limited shareholder rights and placed importance on managerial discretion, and in opposition to that, arguments to strengthen shareholder rights have emerged, with discussions continuing until recently. The same paper notes that discussions on this question are rare in Korea.

Votes are basically one per piece, but whether the votes of small stakes change the outcome depends on how the votes are counted and whether the small stakes pool their intentions. Enterprises that introduced devices to magnify votes had higher dividends and corporate value. After shareholder proposals, governance ratings improved but there was no notable effect on corporate value, and after the introduction of guidelines, market reactions around the voting date became larger than before introduction.

When the Slices Are Concentrated on One Side

The common picture we saw earlier was a company with dispersed ownership. If you trace the slices of 2,980 companies across nine East Asian countries all the way up to their ultimate owners, more than half of the companies were under the control of a single shareholder. This is a method where, if one company holds the slices of another company, you follow the owner of that company, and then the owner above it, until you reach the very top. Management also rarely stood separate from the controlling shareholder (DOI: 10.1596/1813-9450-2054, a 1999 World Bank policy research working paper). In these companies, ownership is concentrated in one place, and management sits close by.

One way to grow that control is by building layers. An ownership structure stacked in layers, such that a company holds slices of another company, and that company in turn holds slices of yet another company, is called a pyramid structure. Suppose that Person A holds just over half of Company X's slices, and Company X holds just over half of Company Y's slices. Person A determines Company X's votes, and Company X's votes determine Company Y's decisions. Therefore, Person A sways Company Y's decisions. Yet among what is left over in Company Y, the share that comes to Person A is half of a half, or roughly a quarter.

In many countries, control has been reinforced by such pyramid structures and devices that depart from the principle of one slice, one vote. These are devices that attach extra votes to the same slice. As a result, voting rights exceed rights to cash flows—in other words, the share of what is left over that we saw earlier (DOI: 10.1596/1813-9450-2054). This is a state of holding many votes while putting up few shares. The same report notes that the patterns of controlling stakes vary by country, and that the concentration of control generally grows fainter as the level of economic and institutional development rises.

The principal-agent problem we saw earlier—the mismatch between those who manage and those who own—arises from several things. These are the separation of ownership and management, differing tolerances for risk, the information gap where those managing know more about the company's condition, and hidden actions that those owning cannot all observe (DOI: 10.1177/0974686217701467, a literature review not specifying countries). The literature has pointed to strong ownership control, the managers' own stakes, independent directors, and various committees as devices to reduce this.

When slices are concentrated in a single shareholder, the same mismatch can arise in a different place: between the shareholder holding a large share and the shareholders holding small shares. Whether an individual holding many company slices—that is, an individual major shareholder—stands on the side of minority shareholders as their stake rises diverged in opposite directions depending on the nature of the company, according to one study (KCI ART001590113 · a domestic academic journal, with no sample description in the abstract). Here, the information gap is the difference between what insiders and outside investors know.

In firms with a large information gap, the larger the individual major shareholder's stake, the greater the scale at which cash was distributed. In fast-growing firms, the tendency to pile up cash inside grew stronger. The authors explain the two results this way. When there are no proper means to communicate the company's condition to the outside, the act of distributing cash itself becomes a signal conveying that condition. When growth opportunities are abundant, the cash kept inside becomes an efficient source of investment financing. Both results are interpreted as decisions to share profits with minority shareholders strengthening when the major shareholder's stake rises.

In firms with a small information gap, it was the opposite. Even when cash was ample, the larger the individual major shareholder's stake, the smaller the scale of cash distribution. The authors read this as the major shareholder increasing the cash under their own control to pursue private benefits. They view that the principal-agent problem between shareholders can deepen and the interests of minority shareholders can be infringed upon. Which of the two directions is more common does not appear in the abstract of this study.

In many countries, controlling shareholders' votes have grown larger than their shares through devices like pyramids. And whether distributing more or less of what is left over when an individual major shareholder's stake rises diverged depending on the nature of the company, according to one study.
