Lesson 1 of 6
What is a stock and what do you actually own?
A stock is a fractional ownership claim on a real business, its assets, and its future profits.
Lesson video
Ownership in plain English
When you buy one share of Apple, you own approximately 0.000000006% of the company. That fraction entitles you to a proportional claim on Apple's net assets (buildings, cash, patents) and future profits. If Apple earns $100 billion in profit and decides to distribute $15 billion to shareholders as dividends, your share gets its fraction.
This is not a metaphor. A stock certificate is a legal document of ownership. The exchange just makes it easy to buy and sell those certificates without meeting the other party in person.
What owning a share gives you
| Right | What it means | Practical impact |
|---|---|---|
| Claim on profits | Dividends (if the company pays them) | Apple pays ~$0.25/quarter per share |
| Claim on assets | If the company is liquidated, shareholders get what is left after debts | Rarely relevant unless the company goes bankrupt |
| Voting rights | One share = one vote on board elections and major decisions | You vote on CEO pay, mergers, auditors |
| Transferability | You can sell your ownership to anyone, instantly, on the exchange | This is why the stock market exists |
Stocks vs bonds vs cash
A bond is a loan: you lend money to a company or government, they promise to pay you back with interest. You are a creditor, not an owner. If the company goes bankrupt, bondholders get paid before stockholders.
Cash in a savings account is a loan to a bank. The bank pays you interest (the savings rate) and uses your money to lend to others.
A stock is ownership. There is no promise of repayment. The value goes up if the company does well, down if it does not. Over the long run (100 years of S&P 500 data), stocks have returned 10.3% per year nominally, vs ~5% for bonds and ~3% for cash. The higher return compensates for the higher uncertainty.
Knowledge check
You own 100 shares of a company with 10 million shares outstanding. The company earns $50 million in profit and pays out 40% as dividends. How much do you receive?
How to think about stock ownership
You own a piece of a real business
Not a number on a screen. Real buildings, patents, employees, and customers.
Your returns come from the business growing
If the company earns more profit over time, your share of those profits grows too.
You do not need to sell to benefit
Dividends pay you cash without selling. Growth increases the value of what you hold.
You do not need to understand how a company makes microchips to own an index fund that holds the company. An index fund owns the entire market for you. This is covered in Lesson 5.
“If I could give myself advice back then: just buy the S and P or the NASDAQ. Not the stock picking stuff.”
Started picking individual stocks on Robinhood in college. Now invests forty to sixty thousand dollars per month in index funds.
Knowledge check
A company has a share price of $10 and 1 billion shares outstanding. Another company has a share price of $500 and 10 million shares outstanding. Which company is more valuable?
