You need a brokerage account before you can buy any stock

A brokerage account is a bank-like account that holds your money and your stocks. You cannot buy shares directly from a company or from the stock exchange itself — you buy through a brokerage firm, which acts as the middleman. The brokerage holds your cash, executes your trades, and keeps records of what you own.

Opening an account takes 10 to 20 minutes online. You will need a Social Security number, a valid ID, proof of address (usually a recent utility bill or bank statement), and a bank account to link for deposits. Most brokerages have no minimum deposit to open the account, though some require you to fund it before you can trade. A few large brokerages — Fidelity, Charles Schwab, Vanguard, E-Trade — have no account minimums and no per-trade fees.

Once your account is open and funded, you can place an order to buy stock in any publicly traded company. The order goes to the exchange, the trade executes (usually within seconds during market hours), and the shares appear in your account.

Key Takeaways

  • You must open a brokerage account with a firm like Fidelity, Charles Schwab, or Vanguard before you can buy stocks.
  • The account opening process requires your Social Security number, ID, proof of address, and a linked bank account, and takes about 15 minutes.
  • Most major brokerages charge no account fees and no per-trade commissions, so the cost to start is only the money you deposit to buy shares.
  • Once funded, you can place a buy order for any stock listed on a U.S. exchange, and the trade typically executes within seconds during market hours.
  • You own the shares outright once the trade settles (usually two business days later), and you can sell them whenever the market is open.

Choosing a brokerage: what actually differs between them

Most brokerages now charge zero commission per trade and have no account minimum, so the differences come down to research tools, user interface, and customer service. A beginner often does not need sophisticated research tools — a simple search for the company name and a look at the stock price chart is enough to start. The real difference is how easy the app or website is to use.

Fidelity and Charles Schwab are known for strong educational resources and customer service by phone. Vanguard is owned by its customers and emphasizes low-cost index funds (funds that track the whole market rather than picking individual stocks). E-Trade and TD Ameritrade have mobile apps that many traders find intuitive. Robinhood and Webull appeal to people who want a very simple, stripped-down interface.

Open an account with whichever brokerage feels easiest to you. You can always open a second account elsewhere later if you want to try a different platform. There is no penalty for having accounts at multiple brokerages.

How to place your first stock order

Once your account is funded, log in and look for a "Buy" or "Trade" button. You will enter the stock ticker symbol (a one- to four-letter code like AAPL for Apple or MSFT for Microsoft). The brokerage will show you the current price and let you choose how many shares you want to buy.

You will also choose an order type. A market order buys at the current market price right now — this is the simplest choice for a beginner and executes almost instantly during market hours. A limit order lets you set a maximum price you are willing to pay; the trade only executes if the stock drops to that price or lower. Limit orders are useful if you want to avoid overpaying, but they may never execute if the price never reaches your limit.

After you place the order, it goes to the exchange. During market hours (9:30 a.m. to 4 p.m. Eastern time, Monday through Friday), a market order executes in seconds. The shares settle two business days later, meaning the money leaves your account and the shares officially belong to you. Until settlement, the shares show in your account but are technically still in transit.

Understanding what you own and what it costs

When you buy a share of stock, you own a tiny piece of that company. If the company has 1 billion shares outstanding and you own 100, you own one ten-millionth of the company. You do not have a say in how the company runs unless you own enough shares to matter (which is rare for individual investors), but you own a claim on the company's future profits.

The price of a stock moves based on what other investors think the company is worth. If investors believe the company will grow, they buy more shares, the price goes up, and your shares become worth more. If investors lose confidence, they sell, the price falls, and your shares lose value. You make money when you sell for more than you paid. You lose money when you sell for less.

The only cost to buy stocks at most brokerages is the price of the shares themselves. There is no commission, no account fee, and no hidden charge. Some brokerages offer fractional shares, meaning you can buy a portion of a share if you do not have enough money for a whole one — for example, you could buy 0.5 shares of a $200 stock for $100.

What happens after you buy: holding, selling, and dividends

Once you own shares, they sit in your account. You can check their value any time the market is open. You can sell them whenever you want during market hours by placing a sell order the same way you placed a buy order. The money from the sale lands in your account two business days later.

Some companies pay dividends — small cash payments to shareholders, usually a few times a year. If you own shares on the dividend payment date, the cash goes into your account automatically. Dividends are optional; many growing companies pay no dividend at all.

If you sell a stock for more than you paid, you owe capital gains tax on the profit. If you hold the stock for more than one year before selling, you pay a lower tax rate (long-term capital gains tax). If you sell within one year, you pay your regular income tax rate (short-term capital gains tax). You do not owe tax until you actually sell — just owning a stock that went up in value does not trigger a tax bill.

Common mistakes beginners make

The biggest mistake is treating stock picking like gambling. Buying a stock because you heard about it on social media or because a friend made money on it is how people lose money fast. Before you buy, spend 10 minutes reading about the company: What does it do? Is it profitable? How does its price compare to its earnings? You do not need to become an expert, but you should understand what you own.

Another common trap is buying high and selling low. When a stock price jumps, people rush to buy, often right before the price falls. When a stock drops, people panic and sell at the bottom. Instead, try to buy stocks you believe in at any price and hold them for years. The longer you hold, the more time the company has to grow and the less short-term price swings matter.

A third mistake is putting all your money into one or two stocks. If that company has bad news, your whole portfolio suffers. Spreading your money across many stocks — or buying an index fund that owns hundreds of stocks — reduces the risk that one bad company will hurt you badly.

Index funds and ETFs: an alternative to picking individual stocks

If picking individual stocks feels overwhelming, you can buy an index fund or an exchange-traded fund (ETF). Both are baskets of many stocks bundled together. An index fund that tracks the S&P 500, for example, owns a small piece of 500 large U.S. companies. When you buy one share of that fund, you own a tiny piece of all 500 companies.

Index funds and ETFs are bought and sold the same way as individual stocks — you search for the ticker, enter how many shares you want, and place an order. The difference is that instead of betting on one company, you are betting on the overall market. Most financial advisors recommend that beginners start with a broad index fund or ETF rather than trying to pick individual stocks.

The cost is also lower. Index funds and ETFs charge a small annual fee (often 0.03% to 0.20% of your money per year) because they require less active management than a fund where a manager picks stocks. Individual stock trading has no ongoing fee, but you have to do the research yourself.

Frequently Asked Questions

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

No. Most brokerages have no minimum deposit, and many offer fractional shares, so you can start with $10 or $100. The smaller your starting amount, the longer it will take to grow, but you can add more money over time. Starting small and learning as you go is better than waiting until you have a large sum.

What time of day should I place a stock order?

You can place orders anytime, but they only execute during market hours: 9:30 a.m. to 4 p.m. Eastern time, Monday through Friday. If you place an order outside those hours, it waits until the market opens. Many brokerages also offer after-hours trading, but prices are less stable and spreads (the difference between buy and sell prices) are wider, so beginners should stick to regular market hours.

What if I change my mind right after I buy a stock?

You can sell it immediately by placing a sell order. There is no penalty for selling right away. However, the price may have moved since you bought it, so you might sell for slightly less than you paid. Once the trade settles (two business days later), the money is back in your account and you can use it to buy something else.

Can I lose more money than I invested?

If you buy stocks outright (not on margin or with borrowed money), the worst that can happen is the stock goes to zero and you lose your entire investment. You cannot lose more than you put in. However, if you borrow money from your brokerage to buy stocks (called margin), you can lose more than your initial investment if the stocks fall sharply.

Should I buy individual stocks or index funds?

Most beginners and long-term investors do better with index funds or ETFs because they are simpler, require less research, and spread risk across many companies. Individual stock picking works if you have time to research companies and the patience to hold through price swings, but it is harder than it looks and most people underperform the market.
