A Stock Is a Small Piece of a Real Business
A coworker leans across the lunch table and says, "I finally bought Apple." What she actually bought is stock — a small ownership claim on the business behind the ticker, not the blinking symbol itself.
Stock is ownership in a corporation, divided into shares. Stockholders ride the company's fortunes: growth and dividends on the way up, losses — possibly total — on the way down.
Stock at a glance
- Owning stock means owning part of a company.
- Returns come from price gains, dividends, or both.
- Market price tracks expectations, not just current results.
- If the company liquidates, stockholders are paid last.
What you own, exactly
A company with 100 million shares outstanding gives a 100-share investor one millionth of the common equity. The slice is tiny, but it rises and falls with judgments about the entire business.
Each unit of that ownership is a share. "Stock" names the security; shares count it.
Where the returns come from
A $40 stock can reach $50 because earnings improve, growth expectations build, or buyers simply pay more for the same story. Price and business are connected, but they don't move in lockstep.
Dividends are the other channel, and they're optional. Boards can raise, cut, or eliminate the payout as conditions change — no company is required to keep paying one.
Where stockholders stand
Ownership sits at the bottom of the capital structure. In a liquidation, employees, tax authorities, secured lenders, and bondholders all have claims ahead of common stockholders.
That ordering is the price of the upside. A lender's return is capped at its interest, while owners keep whatever's left after everyone else — which can be a lot, or nothing.
Price isn't a verdict
A low share price doesn't make a stock cheap, and a high one doesn't make it expensive. Share count, profits, debt, and growth all belong in that judgment.
How owning a business compares with lending to one is its own decision — stocks versus bonds walks through the tradeoff.

Before buying any stock, write one sentence about the business you'd own — if you can't, that's your answer.
