You need a brokerage account, money to invest, and a way to place orders

Buying stocks means purchasing shares of ownership in a company. To do it, you open an account with a brokerage — a firm licensed to buy and sell stocks on your behalf. You deposit money into that account, then use the brokerage's platform (usually a website or app) to place an order for the stocks you want. The brokerage executes the trade, holds the shares in your name, and sends you confirmation. That is the entire sequence.

The barrier to entry is low: most brokerages have no account minimum, charge no commission per trade, and let you start with whatever amount you can afford. The real cost is the price of the shares themselves — a single share of some companies costs under $10, while others cost hundreds. You do not have to buy a whole share; many brokerages now let you buy fractional shares, so you can invest $50 into a $200 stock if you want.

Key Takeaways

  • Open a brokerage account with a firm like Fidelity, Charles Schwab, E-Trade, or Robinhood — most have no account minimum and no commission fees.
  • Deposit money into your account by linking a bank account or transferring funds, then wait for the deposit to clear before you can trade.
  • Research the company and its stock price using the brokerage's tools or free sites like Yahoo Finance or Google Finance before you buy.
  • Place a buy order through the brokerage platform, specifying how many shares you want and what price you are willing to pay (or accepting the current market price).
  • Your shares are held in your account and you own them until you sell them; you can check their value anytime through the brokerage platform.

Choosing a brokerage and opening an account

A brokerage is a company licensed by the Securities and Exchange Commission (SEC) to handle stock trades. The major ones — Fidelity, Charles Schwab, E-Trade, TD Ameritrade, Robinhood, and Webull — all offer similar core services: a platform to buy and sell stocks, no commission per trade, and no account minimum. The differences lie in research tools, educational resources, customer service quality, and the user interface of their apps.

To open an account, you visit the brokerage's website, provide your name, address, Social Security number, and employment information, and link a bank account for deposits. The brokerage verifies your identity and approves the account within minutes to a few hours. You then transfer money from your bank into the brokerage account. That transfer usually takes one to three business days to clear, and you cannot trade until it does.

If you are under 18, you cannot open a brokerage account in your own name. A parent or guardian can open a custodial account (sometimes called an UGMA or UTMA account) in your name, which they control until you reach the age of majority in your state (usually 18 or 21).

Funding your account and understanding settlement

Once your account is open, you link a bank account and transfer money. Most brokerages let you transfer via ACH (Automated Clearing House), which is free but takes one to three business days. Some also offer wire transfers, which are faster but may carry a fee.

After the money arrives, there is a settlement period — the time it takes for the trade to officially complete. For stocks, settlement is two business days after you place the order. This means if you buy a stock on Monday, you own it immediately and can sell it immediately, but the cash does not leave your account until Wednesday. If you sell a stock, you receive the cash two business days later. This matters if you plan to move money in and out frequently.

Some brokerages offer margin accounts, which let you borrow money to buy stocks. This is advanced and carries real risk — you can lose more than you invested. Start with a regular cash account, where you can only spend money you have deposited.

Researching stocks before you buy

Before placing an order, learn what you are buying. Every brokerage platform includes research tools: stock quotes, company information, charts showing price history, and analyst ratings. Free sites like Yahoo Finance, Google Finance, and Seeking Alpha offer the same information without an account.

Look at the company's business (what it does, who its customers are), its recent earnings reports, and its stock price over the past year. Read what financial analysts say about it. Check whether the company pays a dividend — a regular cash payment to shareholders. None of this tells you whether the stock will go up or down, but it helps you understand what you own and whether it matches what you are trying to do with your money.

Avoid buying based on tips from friends, social media posts, or news headlines alone. The most common mistake new investors make is buying a stock because they heard it was going up, then selling in a panic when it drops. Stocks move up and down constantly. If you cannot explain why you own a stock, you probably should not own it.

Placing your first buy order

Once you have chosen a stock, you search for it by ticker symbol (a one- to four-letter code; Apple is AAPL, Microsoft is MSFT) in your brokerage platform. The platform shows the current price and lets you enter an order.

You choose between two order types. A market order buys the stock at whatever the current price is right now — it executes almost instantly but you do not know the exact price until it is done. A limit order lets you set a maximum price you are willing to pay; if the stock reaches that price, the order executes, but if it never does, the order sits open until you cancel it or it expires (usually after 30 or 90 days). For a first purchase, a market order is simpler.

You specify how many shares you want. If you have $500 and the stock costs $100 per share, you can buy 5 shares. If you want to invest $500 but the stock costs $200 per share, you can buy 2 full shares and use fractional shares for the remaining $100 (which buys 0.5 shares). You review the order, confirm it, and it executes. You now own the stock.

Holding and monitoring your investment

After you buy, your shares appear in your account. The brokerage shows you the current value (current price per share times the number of shares you own), your total gain or loss, and the percentage return. You can check this anytime through the app or website.

You own the shares until you sell them. If the company pays a dividend, the cash lands in your account automatically. If you want to sell, you search for the stock again, enter a sell order (using the same market or limit order options), and the shares are gone and the cash is in your account two business days later.

Do not check the price constantly. Stock prices move every second the market is open, and watching minute-to-minute changes leads to emotional decisions. If you are investing for the long term (years, not months), daily or weekly price swings do not matter. If you are investing for the short term, you are taking on much more risk and should understand that before you start.

Tax considerations and record-keeping

When you sell a stock for more than you paid, you have a capital gain, which is taxable income. When you sell for less, you have a capital loss, which can offset other gains. The tax rate depends on how long you held the stock: if you held it for more than one year, it is taxed at the long-term capital gains rate (usually lower); if less than one year, it is taxed as ordinary income.

Your brokerage sends you a tax form (Form 1099-B) each year listing all your trades and gains or losses. Keep records of what you bought, when, for how much, and when you sold it. This makes tax time easier and helps you track your performance.

If you hold stocks in a retirement account like a 401(k) or IRA, the tax rules are different — you may not owe taxes on gains until you withdraw the money, or you may not owe taxes at all. That is a separate topic, but it is worth knowing that not all stock accounts are taxed the same way.

Frequently Asked Questions

How much money do I need to start investing in stocks?

Most brokerages have no minimum, so you can start with $1 if you want. Practically, you need enough to buy at least one share of a stock you are interested in, or enough to buy fractional shares. Many stocks cost between $50 and $300 per share, so $100 to $500 is a reasonable starting amount, but you can begin with less.

Can I lose more money than I invested?

In a regular cash account, no — the worst case is the stock goes to zero and you lose everything you put in. If you use margin (borrowed money), you can lose more than you invested, which is why margin is risky and not recommended for beginners.

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

A stock is a single company. A mutual fund is a basket of many stocks (or bonds, or other investments) managed by a professional. Mutual funds spread your risk across many companies, so one bad stock does not hurt as much. They charge a fee for management. Most beginners find mutual funds or index funds (which track a broad market index) simpler than picking individual stocks.

When can I sell a stock I just bought?

You can sell it immediately if you want, even the same day. There is no holding period. However, if you buy and sell the same stock within five business days, you may trigger a "good faith violation" if you do not have enough settled cash in your account — some brokerages restrict your trading after multiple violations.

Do I have to pay taxes on stocks I have not sold yet?

No. You only owe taxes when you sell and realize a gain (or loss). If a stock goes up in value but you still own it, there is no tax due yet. You also do not owe taxes on dividends in a regular brokerage account (though you do in some retirement accounts).
