Lesson 2 of 31 · Zero to reading a chart

What Is a Share? You Buy a Slice, Not a Company

A share is one piece of a real company; the price on a chart is the price of one piece.

You cannot buy a company. Not the whole thing.

So what exactly are you buying?

A company gets cut into pieces. Every price you see on a screen is the price of one piece.

Last time, two people bought the same share. This is what they bought.

Here is a company. One solid block. Now it gets cut. Ten pieces. Each one is a share, one tenth of the whole thing. Cut it again. A hundred pieces now. The block did not get bigger. It did not get smaller. More slices, each one thinner. Real companies do this to an extreme. A hundred million pieces. The slices are invisibly thin. And the block is exactly the same size it was at the start.

Now the part almost nobody explains. Why would a company cut itself up and sell the pieces? Money. A company that needs cash can borrow from a bank. Then it pays it back, with interest. Or it can sell slices of itself to the public. And it never pays that money back at all. The people who bought the slices are not lenders. They are owners.

So a share is a real piece of a real business. Not a number on a screen. A piece.

Here is a real company on a real day. Every number on this chart is the price of one slice. Not the price of the company. One slice.

And here is what that means. If the whole business becomes worth more, every slice is worth more. Nobody did anything to your slice. The pizza got bigger. Your piece grew with it.

The company is the whole. A share is one piece of it. The price on the chart is what one piece costs.

Here is the mistake. People compare two companies by their share price. This one is eight dollars. That one is two hundred. So the two hundred one must be the bigger company. No. That tells you the size of a slice, not the size of the block. A company can cut itself into ten pieces, or ten billion.

We will come back to this properly later.

Look at any stock price today. Say to yourself: that is the price of one slice.

Check yourself

What is a share?

One piece of a company.

The company cuts itself into twice as many pieces. Does it get bigger?

No. Only the slices get thinner.

Why does a company sell slices instead of borrowing?

It never has to pay that money back.
