Imagine you and your friends start a lemonade stand. Business is booming, and you need money to expand. So you offer people a deal: give us $10, and you'll own a tiny piece of our lemonade empire. That's basically what a stock is — a small piece of ownership in a company.
Stocks = Tiny Pieces of a Company
When a company like Apple or Tesla \"goes public,\" it splits itself into millions (or billions) of tiny pieces called shares. When you buy a share, you literally own a fraction of that company.
Apple has about 15 billion shares. If you buy one share (~$170), you own 0.0000000067% of Apple. Tiny? Yes. But you're still a real owner. If Apple makes money, your share becomes more valuable. If Apple launches a terrible product and the stock drops, your share loses value.
That's the deal with stocks: you share in both the wins and the losses.
Why Do Companies Sell Stocks?
Companies need money to grow — to build factories, hire people, develop products. They have two main options:
- Borrow money (take out loans or issue bonds)
- Sell ownership (issue stocks)
Selling stocks means the company gets cash without having to pay it back. The trade-off? The original owners now share profits with all the new shareholders.
When a company first sells its stock to the public, it's called an IPO (Initial Public Offering). After that, shares trade between investors on exchanges like the NYSE or NASDAQ — the company doesn't get money from those trades anymore.
How Do You Make Money From Stocks?
Two ways:
1. Price goes up (Capital Gains)
You buy a share of Nike at $100. A year later, it's worth $120. You sell it and pocket the $20 profit. That's a capital gain.
2. Dividends
Some companies pay you just for owning their stock. It's like getting a thank-you payment every quarter. Coca-Cola, for example, pays about $1.84 per share per year. Not life-changing, but it adds up — especially if you reinvest those dividends and let compound interest work its magic.
Most teen investors focus on growth stocks (price goes up) rather than dividend stocks, since you probably want your money growing as fast as possible.
What Makes Stock Prices Move?
Stock prices are driven by supply and demand — just like sneaker resale prices.
If everyone wants the new Jordan 1s, the resale price skyrockets. If nobody wants them, the price drops. Stocks work the same way:
- Good earnings report? More people want to buy → price goes up.
- CEO scandal? People panic-sell → price goes down.
- New product launch? Depends on whether people think it'll succeed.
In the short term, stock prices can be wild and unpredictable. In the long term, they tend to follow a company's actual performance. That's why long-term investing beats day trading for most people (especially teens).
How to Buy Your First Stock
As a teen, you'll need a custodial account (your parent opens it, you make the picks). Here's the process:
- Open an account on a teen-friendly platform
- Deposit money (even $5 works — many platforms offer fractional shares)
- Search for the stock you want (use the ticker symbol — AAPL for Apple, NKE for Nike)
- Decide how much to invest
- Hit "Buy"
