Stocks and bonds are two different ways to own a piece of a company or lend money to one

A stock is a small piece of ownership in a company. When you buy a stock, you own a share of that company's assets and profits. If the company does well, your stock can become worth more. If the company struggles, your stock can lose value. You might also receive dividends — small payments the company sends to shareholders from its profits.

A bond is a loan you make to a company or government. When you buy a bond, you are lending money that the borrower promises to pay back on a set date. In exchange, they pay you interest — a percentage of the loan amount — usually twice a year. Bonds are generally less risky than stocks because you get paid back the amount you lent, regardless of whether the company or government thrives.

The core difference: stocks make you an owner, bonds make you a lender. That distinction shapes how much money you can make, how much you can lose, and how long you have to wait to get your money back.

Key Takeaways

  • Stocks represent ownership in a company and can rise or fall in value based on company performance, while bonds are loans that pay fixed interest and return your principal on a set date.
  • Stocks offer higher potential returns but carry higher risk of losing money, whereas bonds offer lower but more predictable returns with less risk.
  • Stock prices change daily based on market demand, but bond prices are more stable unless you sell before maturity.
  • Bonds have a maturity date when you get your money back, while stocks have no end date and you keep them as long as you own them.

How stock ownership works and what you stand to gain or lose

When a company goes public, it divides itself into shares and sells them to raise money. Each share represents a fractional ownership stake. If a company has 1 million shares and you own 100, you own 0.01 percent of that company. If the company becomes more profitable or investors believe it will, demand for shares rises and the price goes up. If the company reports poor earnings or faces problems, the price typically falls.

Your return on a stock comes from two sources: price appreciation (selling the stock for more than you paid) and dividends (cash payments from company profits). Not all companies pay dividends — many younger or faster-growing companies reinvest profits back into the business instead. You have no may provide return. A stock you buy for $50 could be worth $75 in a year or $25. You could lose your entire investment if the company fails.

You can sell a stock whenever the market is open, usually within minutes. This liquidity — the ability to turn it into cash quickly — is one reason stocks appeal to investors who might need access to their money.

How bond lending works and why the returns are more predictable

When you buy a bond, you are lending money to the issuer — a corporation, city, state, or the federal government. The bond comes with a maturity date (when you get your money back) and a coupon rate (the interest rate you receive). A $1,000 bond with a 4 percent coupon pays you $40 per year, usually split into two $20 payments, until maturity. On the maturity date, you receive your $1,000 back.

The risk in a bond depends on who issued it. U.S. Treasury bonds are backed by the federal government and carry almost no default risk — the risk that the borrower won't pay you back. Corporate bonds carry more risk because companies can fail. If a company goes bankrupt before your bond matures, you may lose money. Bond rating agencies like Moody's and Standard & Poor's assign ratings to bonds to signal their risk level. Higher-rated bonds (AAA, AA) are safer but pay lower interest. Lower-rated bonds (BB, B) pay higher interest but carry more risk of default.

Bond prices do fluctuate, but differently than stocks. If interest rates rise after you buy a bond, new bonds pay higher rates, so your older bond becomes less attractive and its price falls if you try to sell it. If interest rates fall, your bond becomes more valuable. But if you hold the bond until maturity, you always get your full principal back regardless of price movements along the way.

Risk and return: why stocks and bonds behave differently

Stocks are riskier than bonds because you have no may provide of return. A company can lose money, cut dividends, or fail entirely. Over long periods — 20 years or more — stocks have historically returned around 10 percent per year on average, but that average masks huge year-to-year swings. You might gain 30 percent one year and lose 20 percent the next.

Bonds offer lower but more stable returns. Investment-grade corporate bonds typically return 4 to 6 percent per year, and Treasury bonds return less but with virtually no risk. You know exactly what you will receive if you hold to maturity. The trade-off is clear: stocks offer higher potential gains but demand you tolerate larger losses. Bonds offer smaller, steadier gains with less volatility.

This is why many investors hold both. Stocks provide growth over decades. Bonds provide stability and income. A common approach is to hold a higher percentage of stocks when you are young and have time to recover from downturns, and shift toward more bonds as you near retirement and need to protect what you have built.

How to buy stocks and bonds

You buy stocks through a brokerage account — an online platform like Fidelity, Charles Schwab, E-Trade, or others. You open an account, fund it with money, and place an order to buy shares. The transaction settles within two business days. You can buy individual stocks or funds that hold many stocks (like index funds or mutual funds), which spread your risk across dozens or hundreds of companies.

Bonds are also available through brokerages, though the process is slightly different. Individual bonds are often bought through a bond broker or your regular brokerage. You can also buy bond funds, which hold many bonds and pay you the interest they collect. Treasury bonds are sold directly by the U.S. government through TreasuryDirect.gov, with no broker needed.

Most people starting out buy stocks and bonds through funds rather than picking individual securities. A fund manager or an algorithm selects the holdings, which reduces the research burden and spreads risk more widely than a single stock or bond.

Tax treatment of stocks and bonds

The money you make from stocks and bonds is taxed differently. Stock gains are taxed as capital gains — the profit when you sell. If you hold the stock for more than one year, the gain is taxed at the long-term capital gains rate, which is lower than your regular income tax rate. Dividends are also taxed, either as ordinary income or as may have access to dividends at the lower capital gains rate, depending on how long you held the stock.

Bond interest is taxed as ordinary income at your regular tax rate. However, interest from municipal bonds (issued by cities and states) is often tax-free at the federal level and sometimes at the state level too. This makes municipal bonds attractive to people in high tax brackets. Treasury bond interest is taxed federally but not by states.

Tax treatment matters when you are deciding where to hold stocks and bonds. Bonds in a regular taxable account can eat up more of your return to taxes than stocks. Many investors hold bonds in tax-advantaged retirement accounts (like 401(k)s or IRAs) and stocks in taxable accounts to minimize the tax hit.

Frequently Asked Questions

Can a stock go to zero?

Yes. If a company goes bankrupt, its stock can become worthless. Shareholders are last in line to receive anything — creditors and bondholders get paid first. This is why stocks are riskier than bonds for the same company.

What happens to my bond if the company goes bankrupt?

Bondholders are ahead of stockholders in the repayment line. You may recover some or all of your money, depending on what assets the company has left. But recovery is not may provide. This is why bond ratings matter — they reflect the risk that the issuer will default.

Should I buy individual stocks or a fund?

Most people benefit from funds because they spread risk across many companies and require less research. Individual stocks offer more control but demand you pick winners and can concentrate risk. Beginners typically start with funds and move to individual stocks only if they have time and interest to research companies.

Do I have to hold a bond until maturity?

No. You can sell a bond before maturity on the secondary market, just like a stock. But the price you receive depends on interest rates and the bond's credit quality at the time you sell. If rates have risen, you will likely sell at a loss.

Which is better for retirement savings?

Most retirement plans benefit from both. A common rule is to hold your age in bonds and the rest in stocks — so a 30-year-old might hold 30 percent bonds and 70 percent stocks. As you age, you shift toward more bonds to reduce volatility near retirement.
