You need a brokerage account, money to invest, and a basic understanding of what you are buying

Investing in stocks means buying partial ownership in companies. You do this through a brokerage account — a financial account that holds your money and executes your trades. You open an account with a brokerage firm (examples include Fidelity, Charles Schwab, E-Trade, or Vanguard), deposit money, and then use that account to buy and sell shares of individual companies or funds that hold many companies at once.

The process itself is straightforward: you choose what to buy, place an order through your brokerage's website or app, and the trade settles within a few days. The harder part is deciding what to buy and understanding the risks. Stock prices move constantly. You can lose money if a company's value falls. You can also gain money if it rises. There is no may provide either way.

Most people starting out do not pick individual company stocks. Instead, they buy index funds or exchange-traded funds (ETFs) — these are baskets of many stocks bundled together, which spreads your risk across dozens or hundreds of companies at once.

Key Takeaways

  • You must open a brokerage account with a firm like Fidelity, Charles Schwab, or Vanguard before you can buy any stocks.
  • Most beginners start with index funds or ETFs rather than individual company stocks because they hold many companies and reduce risk.
  • You need money to invest — there is no minimum for some brokerages, though many recommend starting with at least $500 to $1,000.
  • Stock prices fluctuate daily, and you can lose money if prices fall, so only invest money you will not need for at least five years.
  • Your brokerage account can be a regular taxable account or a tax-advantaged account like an IRA, which changes how you pay taxes on gains.

Opening a brokerage account in three steps

First, choose a brokerage. Look for one that offers low fees, a straightforward interface, and educational resources if you are new to investing. Many brokerages charge no commission to buy stocks or ETFs anymore, though some charge small fees for certain services. Visit the brokerage's website and look for a button that says "Open an Account" or "get your free guide."

Second, complete the account process. You will provide your name, address, Social Security number, employment information, and banking details. This takes 10 to 15 minutes. The brokerage will verify your identity and may ask questions about your investment experience and financial situation. These questions help them understand your needs, not determine whether you can open an account.

Third, link a bank account and deposit money. You can transfer funds from your checking or savings account to your new brokerage account. Most transfers take one to three business days. Some brokerages offer a debit card or check-writing feature so you can move money back out when you need it.

Choosing between individual stocks and funds

An individual stock is a share of one company. If you buy 10 shares of Apple, you own a small piece of Apple. If Apple's value rises, your shares are worth more. If it falls, they are worth less. Individual stocks require research — you need to understand the company's business, its competitors, and its financial health. Most beginners lose money picking individual stocks because this research is harder than it looks.

An index fund or ETF holds dozens or hundreds of stocks in one package. An S&P 500 index fund, for example, holds stock in 500 large U.S. companies. When you buy one share of the fund, you own a tiny piece of all 500 companies. If one company's stock falls, the others may rise, and the overall fund value stays more stable. Index funds and ETFs charge small annual fees (often 0.03% to 0.20% of your money per year), but they require almost no research on your part.

Most financial advisors recommend that beginners start with a low-cost index fund or ETF focused on the overall stock market. This approach is called passive investing. You buy the fund, hold it for years, and let it grow. You do not try to time the market or pick winners. Over long periods — 10 years or more — this approach has historically outperformed most people who try to pick individual stocks.

Understanding taxable accounts versus retirement accounts

A taxable brokerage account is the simplest type. You deposit money, buy stocks or funds, and when you sell them for a profit, you owe taxes on that profit. You can withdraw money whenever you want, with no penalties. There are no contribution limits. This account is good if you might need the money within five years or if you have already maxed out retirement account contributions.

A retirement account — such as a Traditional IRA, Roth IRA, or 401(k) — offers tax advantages. In a Traditional IRA, your contributions may be tax-deductible, and you do not pay taxes on gains until you withdraw money in retirement. In a Roth IRA, you contribute after-tax money, but withdrawals in retirement are tax-free. The catch: you generally cannot withdraw money before age 59½ without a penalty. Contribution limits vary by account type and your income. For 2024, you can contribute up to $7,000 per year to an IRA if you are under 50.

Most people should prioritize retirement accounts first — especially if their employer offers a 401(k) match, which is information programs. Once you have maxed out retirement contributions, a taxable account is the next step.

How much money you need to start

Some brokerages have no minimum deposit. You could technically open an account and buy one share of an ETF for $50 or $100. However, this approach has drawbacks. If you pay a $5 or $10 transfer fee, it eats into a small investment. If you buy individual stocks, commissions and bid-ask spreads (the difference between what buyers and sellers pay) can cost more than your profit.

Most financial advisors suggest starting with at least $500 to $1,000. This amount is large enough that fees do not dominate your returns, but small enough that losing it would not devastate your finances. If you have less, consider saving until you reach this threshold, or start with a high-yield savings account while you save.

After you open an account, you do not have to invest all your money at once. Many people use dollar-cost averaging — investing a fixed amount every month (such as $200 or $500) regardless of whether the market is up or down. This approach reduces the risk of investing all your money right before a market drop.

Common mistakes to avoid when starting out

Do not invest money you will need within five years. Stock prices can fall sharply in the short term. If you need the money in two years and the market drops 20%, you may have to sell at a loss. Only invest money you can leave alone for at least five years, ideally longer.

Do not try to time the market. Many beginners buy when prices are high (because everyone is talking about stocks) and sell when prices are low (because they panic). This pattern locks in losses. If you buy an index fund and hold it, you avoid this trap.

Do not put all your money in one stock or sector. Even experienced investors diversify — they spread money across different companies, industries, and types of investments. A single index fund gives you this diversification automatically.

Do not ignore fees. A fund that charges 1% per year instead of 0.10% will cost you tens of thousands of dollars over 30 years. Always check the fund's expense ratio before you buy.

What happens after you buy stocks

Once you own stocks or funds, you do not have to do anything. You can check your account balance whenever you want, but constant checking often leads to panic selling. Most investors benefit from checking their account quarterly or annually, not daily.

Over time, your investments will generate gains (or losses). If you own individual stocks, some companies pay dividends — small cash payments to shareholders, usually a few times per year. Dividends are automatically deposited into your brokerage account. You can reinvest them (buy more shares) or withdraw them.

When you are ready to sell, you log into your account, select the stock or fund, enter the number of shares you want to sell, and confirm. The sale settles within two business days, and the money appears in your account. You can then withdraw it to your bank account or use it to buy something else.

Frequently Asked Questions

Do I need a lot of money to start investing in stocks?

No. Many brokerages have no minimum deposit, so you can start with $50 or $100. However, fees become a larger percentage of small investments, so most people start with $500 to $1,000. The key is to start, not to wait until you have a large sum.

Can I lose all my money investing in stocks?

If you own a single company's stock and the company goes bankrupt, yes, you can lose your entire investment in that stock. If you own an index fund with hundreds of companies, the chance of losing everything is extremely low — it would require the entire U.S. economy to collapse. Diversification through index funds reduces this risk dramatically.

What is the difference between a stock and a mutual fund?

A stock is ownership in one company. A mutual fund or ETF is a basket of many stocks (or bonds, or other investments) managed as one package. Mutual funds are actively managed by a professional who picks holdings; ETFs are usually passively managed and track an index. ETFs typically have lower fees.

How long should I hold stocks before selling?

The longer you hold, the better. Stock markets historically rise over 10-year periods, even though they fall in the short term. If you are investing for retirement, hold for decades. If you are saving for a house down payment in three years, stocks are too risky — use a savings account instead.

Do I have to report my stock investments on my taxes?

Yes, if you sell stocks for a profit or receive dividends, you must report this on your tax return. Your brokerage sends you a form (usually Form 1099-B or 1099-DIV) showing your gains and dividends. The tax you owe depends on how long you held the stock and your income level. Retirement accounts like IRAs and 401(k)s have different tax rules.
