You need a brokerage account before you can buy stocks

A brokerage account is a bank-like account that holds your money and your stocks. You open one with a brokerage firm — a company licensed to buy and sell stocks on your behalf. The firm holds your cash, executes your trades, and keeps records of what you own. Without an account, you have no way to actually purchase a stock.

Most brokerages let you open an account online in 10 to 20 minutes. You will need a Social Security number, a valid ID, proof of address (a recent utility bill or bank statement), and a bank account to transfer money from. Some brokerages have minimum deposit requirements — often $0, sometimes $500 or $1,000 — but many have dropped minimums entirely in recent years.

The account itself is free to open. You pay commissions only when you buy or sell, and most major brokerages charge $0 per trade now. Some charge account maintenance fees if your balance falls below a certain level, but this is becoming rare.

Key Takeaways

  • You open a brokerage account with a licensed firm like Fidelity, Charles Schwab, or E*TRADE, which takes 10 to 20 minutes online and requires your Social Security number and proof of address.
  • Most brokerages charge $0 per stock trade, though some have minimum deposit amounts or account maintenance fees depending on your balance.
  • Once your account is open and funded, you search for a stock by its ticker symbol, decide how many shares to buy, and place an order during market hours (9:30 a.m. to 4 p.m. Eastern, Monday through Friday).
  • Your first stock purchase can be as small as one share, and fractional shares (portions of a share) are now available at most brokerages, so you can invest any dollar amount you choose.
  • Stock prices move constantly during the trading day, so your order may execute at a slightly different price than what you saw on screen.

Choosing a brokerage: what differs between firms

Major brokerages like Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Robinhood all offer the same core service — a place to buy and hold stocks. The differences are in the details: research tools, mobile app quality, customer service hours, and educational resources.

Fidelity and Charles Schwab are known for strong research tools and phone support available during and after market hours. Robinhood and Webull appeal to people who want a simple, mobile-first experience. E*TRADE and TD Ameritrade sit in the middle. None of these differences matter much for someone buying a handful of stocks, so pick based on which website or app you find easiest to use.

Check whether the brokerage offers fractional shares — this means you can buy a portion of a stock instead of a whole share. If a stock costs $500 per share and you have $100, fractional shares let you own 0.2 shares. Most brokerages now offer this, but it is worth confirming before you open an account.

Funding your account and placing your first order

After you open your account, you transfer money from your bank account to your brokerage account. This transfer usually takes one to three business days. Some brokerages let you trade immediately with unsettled funds, but the safest approach is to wait until the transfer clears.

Once your money is in the account, you search for a stock by its ticker symbol — a one- to four-letter code that identifies each stock. Apple is AAPL, Microsoft is MSFT, Tesla is TSLA. You can search by company name, but the ticker is faster and more precise. When you find the stock, you see its current price, a chart of its price history, and basic information about the company.

You then decide how many shares (or what dollar amount) you want to buy. Most brokerages let you choose between a market order and a limit order. A market order buys immediately at whatever the current price is — it executes fast but the price may shift slightly by the time your order goes through. A limit order lets you set a maximum price you are willing to pay; it only executes if the stock drops to that price or below. Limit orders are safer for beginners because you control the price, but they may never execute if the stock never reaches your limit.

Understanding what happens after you buy

Once your order executes, you own the stock. Your brokerage account shows your holdings, the number of shares you own, what you paid for them, and their current value. This updates throughout each trading day as the stock price moves.

You do not have to do anything with the stock once you own it. You can hold it for years, sell it whenever you want, or buy more. If the company pays a dividend — a cash payment to shareholders — it will land in your account automatically. You can reinvest dividends to buy more shares, or take the cash out.

Your brokerage sends you tax documents each January showing what you bought, sold, and earned. You will need these when you file your taxes, because the IRS taxes both the gains you make when you sell a stock and any dividends you receive.

Common mistakes to avoid as a beginner

The biggest mistake is buying based on a tip or a hot stock you heard about without understanding what the company does or what you are paying for it. Spend 10 minutes reading about the company and looking at its price history before you buy. You do not need to be an expert, but you should know whether you are buying a stable, slow-growing company or a volatile startup.

A second mistake is trading too often. Every time you buy or sell, you pay a commission (even if it is $0, there are tax consequences). Beginners who check their account daily and buy and sell constantly end up with worse returns than people who buy and hold. Set a plan, buy stocks you believe in, and check your account monthly or quarterly instead of daily.

A third mistake is putting all your money into one stock. If that company has bad news, your entire investment drops. Spreading money across different stocks, sectors, and company sizes reduces this risk. Many beginners start with index funds or ETFs — single investments that hold dozens or hundreds of stocks — instead of picking individual stocks.

Tax implications and record-keeping

When you sell a stock for more than you paid, you have a capital gain. The IRS taxes this gain. If you held the stock for more than one year, it is taxed at the long-term capital gains rate, which is usually lower than your regular income tax rate. If you held it for one year or less, it is taxed as ordinary income.

Your brokerage tracks all of this and sends you a form called a 1099 each January. You report your gains and losses on your tax return. If you lose money on a stock, you can use that loss to offset gains from other investments, which can lower your tax bill.

Keep records of what you bought, when you bought it, and what you paid. Your brokerage keeps these records too, but having your own copy makes tax time easier. Many brokerages let you download a cost basis report that shows all this information in one place.

Frequently Asked Questions

Can I buy stocks with less than $100?

Yes. Most brokerages now offer fractional shares, so you can invest any amount you want — $10, $50, $1 — and own a portion of a stock. You do not have to wait until you have enough money for a whole share. Check your brokerage's website to confirm they offer fractional shares before you open an account.

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

A stock is ownership in a single company. A mutual fund or ETF is a basket of many stocks bundled together. When you buy a mutual fund, you own a tiny piece of all the companies in that basket. Mutual funds are less risky because if one company fails, your investment is spread across many others. Stocks are riskier but can have bigger gains.

Do I need to watch the market all day?

No. Most successful investors check their accounts once a month or once a quarter. Watching the market constantly leads to emotional decisions and overtrading. Set a plan, buy stocks you believe in, and let them sit. The stock market is open Monday through Friday, 9:30 a.m. to 4 p.m. Eastern, but you can place orders anytime through your brokerage app.

What happens if the brokerage goes out of business?

Your stocks and cash are protected. The Securities Investor Protection Corporation (SIPC) insures up to $500,000 per account at each brokerage if the firm fails. This means your money and stocks are yours even if the brokerage closes. This protection does not cover losses from bad investments — only losses from the brokerage itself failing.

Should I start with individual stocks or index funds?

Index funds and ETFs are safer for beginners because they spread your money across many companies automatically. Individual stocks require more research and carry more risk. Many beginners start with an index fund to learn how the market works, then add individual stocks as they gain confidence. There is no wrong choice — it depends on how much time you want to spend researching companies.
