You need a brokerage account, money to invest, and about 15 minutes to place your first trade

Buying a stock means purchasing a small ownership share in a company. To do it, you open an account with a brokerage — a firm licensed to buy and sell stocks on your behalf — deposit money, search for the company you want, and place an order. The whole process takes minutes once your account is funded. You do not need a financial advisor, a large sum of money, or special knowledge to start.

The mechanics are straightforward, but the decision of which brokerage to use and which stocks to buy matters more than most people think. This guide walks you through both.

Key Takeaways

  • You must open a brokerage account with a firm like Fidelity, Charles Schwab, E*TRADE, or Robinhood before you can buy any stock.
  • The account opening process requires your Social Security number, proof of identity, and a funding method, and takes 10 to 15 minutes.
  • You can buy stocks in fractional shares at most brokerages now, meaning you can invest $50 or $500 rather than waiting to afford a full share.
  • Once your account is funded, you search for a stock by company name or ticker symbol, enter the number of shares you want, and confirm the order.
  • Your order executes during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays), and you own the shares immediately after.

Choosing a brokerage: what matters and what does not

A brokerage is simply the middleman between you and the stock market. The major brokerages — Fidelity, Charles Schwab, E*TRADE, Interactive Brokers, Robinhood, and others — all connect you to the same stock market and execute your orders at the same prices. The differences lie in fees, account minimums, research tools, and the user experience.

Most brokerages now charge zero commission per trade, meaning you do not pay a fee when you buy or sell a stock. This was not always true; it changed around 2019. Some brokerages still make money from interest on cash you hold in the account, from lending your shares to short sellers, or from premium subscription tiers. Read the fee schedule on the brokerage's website before you open an account.

Account minimums vary. Some brokerages require $500 or $1,000 to open an account; others have no minimum. If you are starting with a small amount, check this first. Fidelity and Charles Schwab have no minimums. Robinhood also has no minimum and is designed for beginners, though it has a reputation for encouraging frequent trading.

The research and education tools matter if you plan to research companies yourself. Fidelity and Charles Schwab offer extensive stock screeners, analyst reports, and educational content. Robinhood offers less, but that is fine if you already know which stocks you want to buy or if you plan to invest in index funds instead.

Opening your account and funding it

The account opening process is the same at every brokerage. You visit their website, click "Open an Account," and answer questions about your name, address, date of birth, Social Security number, employment status, and investment experience. You will upload a photo ID. The whole process takes 10 to 15 minutes.

After you submit your information, the brokerage verifies your identity and approves your account, usually within one business day. Some brokerages approve you instantly. Once approved, you can fund your account by linking a bank account, transferring money via wire, or mailing a check. Bank transfers typically take one to three business days to appear in your brokerage account.

Do not worry if you do not know how to answer questions about your investment experience or risk tolerance. These are required by law, but your answers do not lock you into anything. You can buy any stock regardless of what you said.

Finding and buying a specific stock

Once your account is funded, log in to your brokerage and look for the "Trade" or "Buy" section. You will see a search box where you can type either the company name or its ticker symbol — a one- to four-letter code that identifies the stock. Apple's ticker is AAPL, Microsoft is MSFT, Amazon is AMZN. If you do not know the ticker, type the company name and the brokerage will show you matches.

Click on the stock you want. You will see the current price, a chart of its price history, and basic information about the company. Then click "Buy" or "Place Order." The brokerage will ask how many shares you want to buy. If the stock costs $150 per share and you have $500, you can buy 3 full shares (for $450) and have $50 left over, or you can buy 3.33 fractional shares for exactly $500. Most brokerages now allow fractional shares, which is useful if you are starting with a small amount.

After you enter the number of shares, you will see a summary showing the total cost and any fees. Review it and click "Confirm" or "Submit Order." Your order is now placed. If the market is open (9:30 a.m. to 4 p.m. Eastern time on weekdays), your order executes within seconds and you own the shares. If the market is closed, your order waits until the next market open.

Understanding order types and timing

When you place an order, you are choosing between a market order and a limit order. A market order buys the stock at whatever the current price is right now. A limit order lets you set a maximum price you are willing to pay; if the stock never reaches that price, the order does not execute. For a beginner buying a stock you plan to hold for years, a market order is simpler and fine.

Timing matters only if you are trying to catch a specific price. If you place an order during market hours, it executes within seconds at the current market price. If you place an order after the market closes (after 4 p.m. Eastern) or before it opens (before 9:30 a.m. Eastern), your order waits in a queue and executes when the market opens the next business day. Some brokerages offer extended-hours trading, but that is a feature for experienced traders and is not necessary to start.

What happens after you buy: ownership and next steps

Once your order executes, you own the shares. Your brokerage account will show your holdings, the price you paid per share, the current price, and your gain or loss. You do not receive a physical stock certificate; ownership is recorded electronically.

You can hold the stock as long as you want. You can sell it anytime the market is open by going to your holdings, clicking the stock, and clicking "Sell." You will pay no commission at most brokerages. If the stock price has risen since you bought it, you will owe capital gains tax on the profit when you sell; if it has fallen, you have a loss (which can offset other gains). This is why most financial advisors recommend holding stocks for at least a year if possible — long-term capital gains are taxed at a lower rate than short-term gains.

If the company pays a dividend (a cash payment to shareholders), it will be deposited into your account automatically. You can reinvest it by buying more shares, or leave it as cash.

Common mistakes to avoid when starting out

The biggest mistake is trading too often. Every time you buy and sell, you risk locking in a loss or missing a gain. Most research shows that people who buy and hold for years do better than people who trade frequently. Decide why you are buying a stock before you buy it, and stick to that plan.

The second mistake is putting all your money into one stock. If that company has bad news, your entire investment suffers. Most advisors recommend owning at least 10 to 20 different stocks, or buying an index fund that owns hundreds of stocks at once. If you are just starting, an index fund is often a better choice than picking individual stocks.

The third mistake is buying on emotion — buying because a stock is "hot" or selling because you are scared of a price drop. Write down your reason for buying before you buy, and refer back to it when the price moves.

Frequently Asked Questions

Do I need a lot of money to start buying stocks?

No. Most brokerages have no account minimum, and fractional shares mean you can invest $10, $50, or any amount. You do not need to wait until you can afford a full share.

Can I buy stocks on my phone?

Yes. Every major brokerage has a mobile app that works the same way as the website. You can open an account, fund it, and buy stocks entirely on your phone.

What if I change my mind after I place an order?

If the market is still open and your order has not executed yet, you can cancel it. Once the order executes and you own the shares, you can only sell them. You cannot undo a completed trade.

Do I owe taxes when I buy a stock?

No. You owe taxes only when you sell the stock and have a gain. If you hold it and the price rises, you owe nothing until you sell.

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

A stock is ownership in one company. A mutual fund or index fund is a basket of many stocks bundled together. Funds are simpler for beginners because they spread your risk across many companies automatically.
