What a share actually is

When a company incorporates, it divides its ownership into units called shares. Owning one share of a company with 100 million shares outstanding means you own one hundred-millionth of that business: the same fraction of its factories, brand, cash, debts, and — most importantly — its future profits.

That fraction is what you are buying. The ticker symbol is just a label the exchange uses to route your order. If you cannot describe what the business sells, to whom, and why customers keep coming back, you do not yet know what you own.

There are only two ways a share puts money in your pocket. First, dividends: cash the company chooses to distribute from its profits. Second, capital gains: someone later pays you more per share than you paid, usually because the business now earns more, or is expected to.

Notice that both routes trace back to profit. Price moves feel like the whole game because they are visible every second, but over years the profit stream does the heavy lifting.

Price is what the last buyer and seller agreed on. Value is your estimate of the cash the business will produce for owners over its life. They are related but not the same, and the gap between them is where analysis lives.

Market capitalisation — share price multiplied by shares outstanding — is the market's price tag for the whole company. It is the number to compare across companies, not the share price, because share price alone tells you nothing about size.
