Stock
Age 10+A tiny piece of a company that you own. If the company does well, your stock can be worth more.
At a glance
A stock is a tiny ownership slice of a company. When you buy a share of Apple, you literally own a fraction of Apple. If the company does well, your share is worth more. If it doesn't, your share is worth less. Stocks are the building block of most adult investing — both as individual shares and packaged into index funds and ETFs.
Example sentence
"We bought one share of Apple so you can see how stocks work."
Why this matters for kids
Stocks are how most long-term wealth is built in modern economies. Adults who own stocks (directly, through 401k retirement plans, or via index funds) build wealth meaningfully faster than adults whose savings sit only in cash. Kids who own a single share of a company they recognise — Apple because they have an iPad, Nike because they wear shoes, Disney because they've been to Disneyland — develop a sudden, personal interest in business news and stock prices. They check the share price. They notice when their company makes the news. They form opinions about the products. That curiosity is the on-ramp to a lifelong relationship with investing, and one share of stock is enough to start it. Beyond the educational benefit, owning stock young teaches the most important investing lesson: prices move, sometimes meaningfully, and the right response is usually patience. A kid who watches their one share drop 20% in a market correction and recover over the next year has just learned the entire game in one round.
How to teach it
Open a custodial brokerage account (Fidelity, Schwab, Greenlight, Stockpile all support kids). Buy one share of a company the kid actually uses — Netflix, Nintendo, Nike, Disney, Starbucks, Roblox, Apple, Tesla — anything they recognise. Track the price on a paper chart or in a shared note. Check back every few months, not daily. When the price moves materially, talk about why: company earnings, sector news, broader market move. Don't get into the weeds; the goal is curiosity, not analysis. After a year or so, introduce the index fund: "you own one share of Apple, but a single share of an S&P 500 ETF means you own a tiny piece of 500 companies including Apple." That single conversation is most of what they'll ever need to understand about diversified investing. For older teens with a Roth IRA, set up automatic monthly contributions — even $25/month from age 16 compounds to real money by retirement.
Common misconceptions
- Stocks are gambling. Day-trading individual stocks is closer to gambling. Long-term investing in diversified index funds is closer to "owning a piece of the economy."
- You need a lot of money. Fractional shares now let you buy parts of expensive stocks for as little as $5. The barrier is gone.
- Stocks always go up. Over 30+ year periods historically yes, but year-to-year stocks fall regularly. The patience to ride out drops is the lesson.
