What a share is
You open the business pages and find a line like this one. It isn't hiding anything — it's just a sentence in a language nobody taught you. Eight minutes from now it will read like English.

Blurred on purpose. That's roughly what it looks like to you today.
A company cut into pieces
A share is a piece of a company. Not a betting slip, not a number that moves on its own: it is ownership. Whoever holds a share owns a fraction of the company, and is entitled to a fraction of whatever profit it hands out.
Start small. Aurora Bakery is worth 500,000 and was cut into 10,000 equal pieces. Each piece costs 50. Last year the bakery made 60,000 in profit and handed half of it to the owners.
- You hold
- Of the company
- It cost
- Your share of the profit
A listed company is exactly this, with more zeros and one difference that changes everything: the pieces can be sold to anyone, at any moment. That liquidity is what creates the price you see in the paper.
From here on we look at the U.S. market — the NYSE and the Nasdaq, home of the S&P 500 and of the companies that show up in every story. Not a preference: it's simply where almost everything you read comes from. So the figures move to dollars from here on.
A share's price is not the company's size
An $8 share is not "cheaper" than a $50 one. It is just a smaller piece of a cake that may be far bigger. To find the size of the company, multiply the price by the number of pieces — that is the market capitalisation, or market cap.
Aurora Foods
Bertoldo Coffee
Berkshire Hathaway has two classes of the same company on the market. Class B was created worth one fifteen-hundredth of class A — so the two prices on screen sit enormously far apart without there being two companies. Living proof that share price and company size are different things.
Two ways to make money, and only two
Everything else is a variation on these. Either the company pays you part of its profit, or somebody buys your slice for more than you paid.
Dividend
The company made a profit and hands part of it to the owners. It lands in your account without you doing anything and without selling anything. In the United States no law requires a company to pay a dividend — it is the board's decision, and several of the largest technology companies went decades without paying one.
Appreciation
Somebody comes to want your slice for more than it cost. That gain is only yours once you sell — until then it is a price on a screen, not money in your pocket. And the price can fall just as easily.
The letters that name the company
On the U.S. market the code — the ticker — is one to five letters, assigned by the exchange. The letters carry no hidden meaning: they are a short nickname. Historically the NYSE used up to three letters and the Nasdaq four, but that stopped being a rule a long time ago.
What is worth knowing is what appears after the letters. When a company has more than one class of share, each class gets its own ticker.
Now read the line
It's the same one from the top, unblurred. Tap each part.
Five pieces of information
Each block above answers a different question. Tap one of them.
Five taps and the line is done.
If this landed, the lesson did what it promised
- A share is a piece of a company, not a bet.
- A share's price alone does not tell you the company's size.
- The return comes from a dividend or from appreciation — and only the first needs no selling.
- When a company has more than one class of share, each class has its own ticker.

This track is educational material. It explains the vocabulary and the mechanics of the market so that you can read a news story without depending on anyone else's interpretation. It is not a recommendation to buy or sell, and none of the companies in the examples exist — the figures were kept round so the arithmetic stays visible.
