What You Own When You Own a Stock
A share isn't a lottery ticket with a company logo on it. It's a legal claim on a real business: its profits, its assets, and its future. Price is just what someone will pay you for that claim today.
A share is a slice, and the slicing is arbitrary
A share of common stock is a unit of ownership in a corporation: a claim on its earnings and assets, usually a vote, and any dividend it declares. The most you can lose is what you put in — the company's debts are not yours. That is limited liability.
Here is the part that trips up almost everyone. A company decides how many shares to cut itself into, and that decision is close to arbitrary. Two businesses of identical size can have wildly different share prices simply because one sliced itself more finely.
So the price of a single share tells you nothing on its own. What tells you the size of the company is price multiplied by the number of shares — its market capitalization.
Share price × shares outstanding. This is the size of the company. The share price by itself is a slicing decision.
Where your money actually goes
There are two markets, and confusing them is the source of a lot of muddled thinking about what investing does.
In the primary market, a company sells new shares to investors and receives the cash — an IPO, or a later share issue. This is the only time buying stock funds the business.
Everything after that is the secondary market: investors trading with each other on an exchange. Buy shares of a long-listed company today and your money goes to whoever sold them to you. The company gets nothing and does not even know you bought.
That does not make the secondary market pointless — it is what makes the primary market possible. Nobody would fund a company at an IPO if the stake could never be sold again.
Two ways a stock pays you, one honest measure
A stock can pay you twice. Capital appreciation is the price rising above what you paid. Dividends are cash the company hands out from its profits, usually quarterly, and they arrive whether the price went up or not.
Total return is both together, and it is the only honest measure of how an investment did. Judging a dividend-paying stock on price alone systematically understates it — you are ignoring money that already landed in your account.
This is also why long-run market return figures are quoted 'with dividends reinvested'. Strip the dividends out of a century of US stock returns and you remove a large share of the total.
A stock is fractional ownership of a business. Its long-run value comes from what the business earns, not from what the chart did last week — and the share price alone tells you nothing about how big or how cheap a company is.
