What Is a Stock?

Imagine you baked a giant cookie. The biggest, best cookie in the world. Now imagine you break it into a hundred tiny pieces, and you sell each piece to a different person. Every person who buys a piece owns a little part of your cookie.

That's exactly what a stock is.

A stock is a tiny piece of a company. When a company wants to grow, it can split itself into little pieces — called shares — and sell them to people. If you buy one share, you own a little slice of that company. You are now a part-owner. A shareholder. That's the fancy word for it, and now you know it.

Here's the cool part. If the company does well — more customers, more cookies sold — your little piece becomes worth more, and other people will pay you extra for it. But if the company struggles, your piece can be worth less. That's the deal: you share in the wins, and you share in the losses.

Almost every company you know is split into pieces like this. Your favorite phone maker. Your favorite burger place. Your favorite game company. And regular people — people like you — can own a piece of all of them.

So remember: a stock isn't some mysterious Wall Street magic. It's just a little piece of a real company, owned by a real person. And now you know exactly what one is.
