A share of stock looks simple on the surface — a number in an app, a price that changes every second, something people talk about at dinner parties and argue about on the internet. But underneath that simplicity is a specific legal and financial claim that most people, including many regular investors, have never had properly explained to them.
So let's start with what a share actually is — not the definition, but the mechanics. And to get there, you need to understand a particular idea: the residual claim.
When a company earns revenue, that money does not flow freely to shareholders. It moves through a queue first. Suppliers get paid. Employees get their wages. The bank gets its interest. The tax authority takes its cut. Whatever is left after all of those prior claims are satisfied — that remainder — belongs to the shareholders. That is what it means to hold a residual claim. You own what is left.
Think of it this way. You are at the back of a line, and everyone ahead of you has a fixed entitlement. When business is good, the line moves quickly and there is plenty left by the time it reaches you. When business is bad, the people ahead of you still get paid first — every last one of them — and you collect whatever remains, which could be very little or nothing at all. According to multiple sources on the structure of shareholder rights, common stockholders hold only these residual claims on the firm's cash distribution after the priority claims of senior lenders and bondholders are met.
This is important because it explains two things at once: why equities have historically offered higher returns than bonds over long periods, and why they are more volatile. The lender who gave the company a loan gets a fixed interest payment regardless of whether profits were spectacular or disappointing. The shareholder's return floats — it is directly tied to how large that residual pool turns out to be. Greater uncertainty, greater potential reward. That is not a marketing slogan; it is a structural consequence of where shareholders sit in the payment queue.
Now, being last in line also means being first when things go very well. If the company earns far more than expected, the fixed obligations stay fixed — the bank still gets only its agreed interest — and after tax, the extra profit belongs to shareholders — paid out as dividends or kept in the business on their behalf. So the residual claim is not just a risk to bear; it is the mechanism through which shareholders capture upside that nobody else in the queue is entitled to.
Here is a fair objection before going further. Some people argue that shares have become so disconnected from real business performance that they function more like casino chips than ownership stakes. Prices jump on rumours, fall on tweets, and seem to have little to do with the factories and employees underneath. That view deserves a serious hearing, and we will come back to it directly. But to evaluate it properly, you first need the full picture of what a share actually entails — and that requires one more foundational concept.
Limited liability. It sounds technical, but it is one of the most consequential legal inventions in modern economic history. Without it, buying shares in a company would mean accepting unlimited personal exposure to that company's debts. In that world, if a company collapsed owing money, its creditors could come after shareholders' personal assets — their savings, their homes, everything. Limited liability is what stops that from happening. That would make ordinary share ownership essentially unthinkable for most people.
Limited liability changed that entirely. As the corporate law literature describes it, shareholders are legally considered part-owners but are not liable for the company's debts. Their financial risk is capped at the amount they paid for their shares. You can lose everything you invested — that risk is real — but creditors cannot reach beyond that. The losses stop at your investment.
This single feature is what made it possible for companies to attract capital from strangers. A person who has never visited a company's offices, never met its management, and has no influence over its day-to-day decisions can still invest, because they know precisely what their worst-case outcome is. That clarity — that capped downside — is what opened share ownership to the general public and allowed large companies to aggregate capital from thousands or millions of individual investors.
So, to recap where we are: a share is defined by two interlocking features. The residual claim establishes what you are entitled to — the profits that remain after everyone with a prior claim is satisfied. Limited liability establishes what you can lose — the amount you paid, and nothing more. Together, these two features define the instrument. They explain both why people are willing to hold shares and why companies can attract those investors. You need both ideas to understand what comes next.
Now, how does a company actually get shares into the hands of investors? This is where the initial public offering — the IPO — comes in, and where an important distinction is often missed.
When a company goes public, it is participating in the primary market. The company creates new shares and sells them, typically with the help of investment banks, directly to investors. The money from those sales flows into the company. This is the fundraising event — the moment when the company exchanges a portion of ownership for capital it can use to grow, repay debt, or pursue new projects.
Once those shares are in investors' hands and listed on an exchange — like the Australian Securities Exchange — something fundamental shifts. The company is no longer involved. Investors trade those shares with each other. If you buy shares of a listed company today, your money does not go to the company. It goes to whoever sold you those shares — another investor who decided they wanted to exit. The exchange is the venue for that transaction. The ASX is a marketplace where buyers and sellers find each other; everyday trading on it is not fundraising for the businesses whose names appear on the ticker.
This distinction matters practically. Companies raise capital when they issue shares, at an IPO or in a later share offer, not each time one investor sells to another. What happens on the exchange after that is a conversation between investors about what those ownership stakes are worth. The price discovered on the exchange every day is not the company asking for money — it is investors collectively expressing their view of the company's future.
On the mechanics of IPOs specifically: research shows that in the United States, the average IPO was underpriced by 14.8% between 1990 and 1998, and by roughly 12% between 2001 and 2009. In plain terms, companies sold their shares to the public at a price lower than the market was prepared to value them on the first day of trading. New investors often saw an immediate gain; the company, by contrast, received less capital than it might have. Why does this happen? Companies and their underwriting banks face genuine uncertainty about where demand will land, and they tend to price conservatively to ensure the offering succeeds. It is a structural feature of the process — not a mistake exactly, but a cost of accessing public capital markets.
Once shares are listed and trading begins, the exchange becomes what most people picture when they think of the stock market. The ASX operates as a venue where investors can buy and sell shares among themselves. To be clear: once shares are listed, the company no longer receives money from trades between investors. The exchange is where investors trade with each other — it is not a continuous fundraising tap for the business.
So what drives the price of a share on that exchange from one day to the next? This is where the question gets interesting, and where a piece of research from the Swiss stock market illuminates something that is easy to underestimate.
Share prices do not move because factories change in value overnight. The physical assets of most large companies are relatively stable from one week to the next. What moves constantly is something more abstract: investors' expectations about how much money the company will earn in the future. A share price is not a photograph of what the company owns today. It is a forecast — a collective bet on future profits, discounted back to a present value.
Research published in Financial Markets and Portfolio Management examined how much of the variation in the price-to-earnings ratio — the most widely used measure of how expensive a stock is relative to what it earns — could be explained by investors' subjective earnings growth expectations. The answer, at the twelve-month horizon: 59%. In that Swiss data, a little over half of the movement in how expensive stocks looked was statistically explained by changes in investors' earnings growth expectations. Not because a building changed hands, not because last quarter's numbers were revised, but because the collective forecast moved.
That is worth sitting with. Roughly 59 percent of the movement in how cheap or expensive Swiss stocks looked was explained by changing earnings expectations — what investors expect to happen, not what has already happened.
This brings us back to the casino critique, which is the strongest version of the objection to treating shares as genuine ownership claims. The argument goes like this: if prices are driven by expectations, and expectations are essentially subjective and constantly shifting, then buying a share is really just a bet on what other people will think tomorrow. There is no anchor. The price can go anywhere. That sounds a lot like gambling.
This is a serious argument. And it is not entirely wrong. Research on investor behaviour in Chinese markets, using data on periods when markets were falling, found that investors do shift toward lottery-like stocks during downturns — stocks with extreme potential payoffs and low probability of winning, structurally similar to lottery tickets. The theoretical explanation comes from prospect theory, developed by Kahneman and Tversky, which holds that people tend to be risk-seeking when they feel they are already losing. When a market falls and investors feel like they are in the loss domain, the gambling impulse intensifies. And critically, that research found that holders of lottery-like stocks earn negative subsequent returns on average. The gambling behaviour is real, and it is measurable, and it costs the people who exhibit it.
So the casino critique contains something true: some investors do treat shares as lottery tickets. That behaviour exists. It is documented. It produces predictable and poor outcomes for those who engage in it.
But — and this is where the critique overshoots — the fact that some participants behave like gamblers does not make the instrument itself a lottery ticket. A share still represents a legal residual claim on a real company's real future profits. The Eicher Motors example makes this concrete. At that company's annual general meeting in August 2021, shareholders voted on whether to reappoint the managing director. About 73% of votes cast supported the reappointment. But the resolution required 75% approval to pass, so it failed. The managing director was not reappointed. Shareholders — as a collective body — exercised actual power over a significant management decision, and the outcome changed because of how they voted.
That is not what happens at a casino. A casino does not give you a vote on how the house is run.
Shareholder rights go further than voting. As the literature on corporate governance describes, shareholders have the right to inspect financial records, to receive dividends when the board declares them, to receive their residual share if the company is ever liquidated, and to sue the company or its directors for breaches of fiduciary duty. These are enforceable legal rights, not merely nominal ones.
But here is an honest complication: the voting right is theoretical for most individual shareholders, and the data makes this stark. In the 2017 proxy season in the United States, retail shareholders — everyday investors like most people listening to this — voted approximately 28% of the shares they held. Institutional investors — large professional funds — voted approximately 91% of theirs. The gap is enormous. It means institutional votes carry most of the weight, and in a close contest their decisions can matter far more than retail ones. One source on shareholder governance notes that a single retail vote is mathematically small and only matters when aligned with institutional shareholders.
And separately, research on activist investors points out that the power to vote and pressure boards can be used against long-term shareholder interests just as readily as for them — pushing management toward short-term price performance at the expense of sustainable value creation. Voting power is not inherently a protective force. It depends on who exercises it and toward what end.
Dividends carry their own honest qualification. They are discretionary. A board declares a dividend when it chooses to; it can also choose not to, and shareholders cannot legally compel the company to pay out profits. The residual claim includes dividends, but it does not guarantee them.
Let's also acknowledge what the research does not fully answer. The 59% figure on earnings expectations comes from Swiss market data. Whether the same pattern holds for ASX-listed companies, and whether it holds with the same magnitude, is not established by this research. Applying Swiss findings to Australian markets is reasonable as a hypothesis, not as a settled fact.
And the capital structure question — why a company chooses to raise money by issuing shares rather than simply borrowing — is only partially addressed. The research confirms that issuing shares means giving up a portion of residual profits in exchange for capital. But the full reasoning behind how companies weigh that trade-off against the cost of debt is territory the sources here leave largely open.
So here is where all of this lands. A share is a legally defined residual claim on a company's future profits. It comes with limited liability, which caps your downside at what you paid. It comes with voting rights, which are real but which most retail investors exercise rarely, leaving institutional investors to dominate collective decisions. It comes with the right to dividends when declared — and when the company thrives, those dividends and the rising market value of your stake reflect the surplus that accumulates once every other claimant is satisfied.
Share prices move because expectations move. In the Swiss data we looked at, more than half of the variation in how expensive stocks looked relative to their earnings was explained by changes in what investors expected about future profits — not by changes in what companies owned that day. That forward-looking quality is what makes prices volatile. It is also what makes gambling behaviour psychologically understandable: if prices are driven by expectations about an uncertain future, and if you are already feeling like you are losing, the temptation to chase extreme outcomes is real and documented.
But the instrument itself is not the behaviour of its most excitable participants. A share is a claim, grounded in company law, on real future earnings. The casino analogy captures something true about how some people use it. It does not capture what it actually is.
Three questions remain open: how quickly markets correct when prices move out of line with fundamentals, whether the patterns observed in Swiss and Chinese and American markets apply with the same force to Australian investors trading on the ASX, and whether the 59% figure for earnings expectations driving valuations holds outside the Swiss context where it was measured. Those are worth holding onto as honest uncertainty rather than filling them in with confidence the evidence does not support.
