Stocks and Bonds Explained: What You Actually Own

A stock is a small piece of a company. A bond is a loan you make. What each one really is, with numbers you can follow.

Two words come up in every money story. Here is what each one actually is.

Stocks: a piece of a company

A stock, or share, is a small piece of ownership in a company. Own one and you own a tiny slice of that business.

Example. You buy one share at $50. If the company does well the share might be worth $60 later. If it does badly it might be worth $40. Some companies also pay owners a slice of the profit, called a dividend, perhaps $1.50 a year on that $50 share.

Share prices swing, sometimes sharply, which is why stocks suit money you will not need for years. Most people own them through a fund holding hundreds of companies rather than betting on one.

Bonds: a loan you make

A bond is a loan you make to a government or a company. They pay you interest for a set period, then return your money.

Example. You lend $1,000 for ten years at 4 percent. You receive $40 a year, and your $1,000 back at the end. Nothing more, nothing less, as long as the borrower can pay.

Bonds usually move more gently than stocks. The two real risks are that the borrower cannot pay, and that inflation makes those fixed $40 payments worth less over time.

Why people hold both

Stocks and bonds often move differently, so holding both smooths the ride. The closer you are to needing the money, the more of it usually sits in the steadier option, but the right mix depends on your situation, not a rule of thumb.

One thing to watch

The 10-Year Treasury Yield on our Money Matters page is simply the interest rate on a bond issued by the U.S. government. Mortgage rates tend to follow it, which is why a bond number ends up on a page about home loans.

What this means for you

• If you cannot explain what a product owns, do not buy it yet.
• A fund spreads risk across many companies; a single share does not.
• Bonds are steadier, not risk free.
