What is a Stock?
A stock is a unit of ownership in a corporation that represents a claim on part of the company's assets and earnings. When you buy stock, you become a shareholder with rights that typically include voting on major company decisions and receiving dividends if the company distributes profits, though you also assume the risk that your shares may lose value.
How does stock ownership actually work?
Stock represents fractional ownership in a corporation divided into shares. When a company issues 1,000,000 shares and you buy 1,000, you own 0.1% of that business.
What are the two main types of stock?
Common stock is the standard form giving you voting rights and potential dividends, but dividend payments aren't guaranteed—the board decides each quarter whether to distribute profits or reinvest them. Preferred stock functions like a hybrid between stocks and bonds: you typically receive fixed dividend payments before common shareholders get anything, and you have priority if the company liquidates, but you usually forfeit voting rights.
How do you make or lose money from stocks?
You profit two ways: capital appreciation and dividends. Capital appreciation means selling shares for more than you paid—buy 100 shares at $50 ($5,000 total), sell at $75 ($7,500), and you've gained $2,500 before taxes and fees.

What's the difference between stocks and bonds?
Stocks make you an owner; bonds make you a lender. When you buy a corporate bond, you're lending money to the company at a fixed interest rate for a set term—lend $10,000 via a 5-year bond at 4% interest, and you receive $400 yearly plus your $10,000 back at maturity.
When does owning stock actually matter for your finances?
Stock ownership becomes financially significant when you're building long-term wealth, especially for retirement. The difference between investing $500 monthly in stocks versus keeping it in a 0.5% savings account is substantial: at 9% average annual returns over 30 years, that monthly investment grows to approximately $900,000, compared to about $195,000 in savings.
FAQ
Can anyone buy stocks?
Yes, any U.S. resident age 18+ can open a brokerage account and buy stocks with no minimum wealth requirement. Many brokerages now allow fractional share purchases, so you can invest $10 in a stock trading at $500 per share.
Do all stocks pay dividends?
No. Growth companies like Amazon and Tesla historically paid zero dividends, reinvesting all profits to expand.
What happens to your stocks if the company goes bankrupt?
Common stockholders are last in line during bankruptcy. Creditors and bondholders get paid first from remaining assets; common shareholders usually receive nothing.
How quickly can you sell stock and get your money?
You can sell stock during market hours (9:30 AM–4:00 PM ET weekdays) and the transaction executes within seconds. However, settlement takes two business days (T+2), meaning the cash appears in your account two days after the sale.

Investing for beginners: accounts, assets, and risk
Before selecting an investment, identify the goal, time horizon, need for liquidity, and ability to tolerate losses. A brokerage account can hold cash, stocks, bonds, mutual funds, exchange-traded funds, and other permitted assets. The account type affects taxes and access, while the investments determine much of the risk and potential return. Fees, trading costs, fund expenses, and taxes can reduce results.
A stock represents an ownership interest in a company, while a bond generally represents money lent to an issuer. An index fund seeks to track a specified market index rather than selecting securities to outperform it. Mutual fund vs ETF differences can include trading method, pricing, minimums, and tax characteristics. Diversification spreads exposure but cannot eliminate loss. REITs provide real estate exposure with market, property, interest-rate, management, and liquidity risks.
