You need a brokerage account, money to invest, and a decision about which stock to buy

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. You fund that account with cash, search for the stock you want by its ticker symbol (a short code like AAPL for Apple), enter how many shares you want, and confirm the purchase. The brokerage executes the trade, and the shares appear in your account within a few seconds to a few days depending on the settlement process.

The entire process is straightforward once you have the account open. The harder part is deciding which stock to buy and understanding what you are actually buying — a piece of a real business, not a lottery ticket. This guide walks you through the mechanics of opening an account, placing an order, and what happens after you buy.

Key Takeaways

  • You must open a brokerage account before you can buy any stock, and most brokerages let you open one online in under 15 minutes with a Social Security number and bank account.
  • You place a stock order by searching the ticker symbol, choosing how many shares you want, and selecting an order type — most beginners use a market order, which buys at the current price immediately.
  • Your money is deducted from your account when you buy, and the shares settle in your account within one to three business days depending on the brokerage.
  • You own the shares outright once they settle, and you can sell them anytime the market is open, though selling at a loss or gain has tax consequences you should understand before you trade.

Opening a brokerage account

A brokerage is a company licensed by the Securities and Exchange Commission (SEC) to buy and sell stocks for customers. You cannot buy stocks directly from a company — you must go through a brokerage. Most major brokerages (Fidelity, Charles Schwab, E-Trade, Robinhood, Webull, and others) let you open an account online without visiting an office.

The account opening process takes 10 to 20 minutes. You will need your Social Security number, a government-issued ID, your address, and a bank account to link for deposits. The brokerage verifies your identity electronically, and you can usually start trading the same day or the next business day. Some brokerages require a minimum deposit to open an account (often $0 to $500), though many have eliminated minimums entirely. Check the brokerage's website for current requirements.

Once your account is open and funded, you are ready to place an order. The brokerage holds your cash in a money market fund or cash sweep account until you use it to buy stocks.

Finding and selecting a stock to buy

Every publicly traded company has a ticker symbol — a short code that identifies it on the stock market. Apple is AAPL, Microsoft is MSFT, Tesla is TSLA. You find the ticker by searching the company name on your brokerage's website or by searching "[company name] ticker" online.

Once you have the ticker, you search for it in your brokerage account. The brokerage will show you the current price per share, the day's trading activity, and historical price charts. You can also see news, financial statements, and analyst commentary — most brokerages include these tools free. Read what you can about the company before you buy, but understand that past price performance does not predict future results.

Decide how many shares you want to buy. If a stock costs $150 per share and you have $1,500 to invest, you can buy 10 shares. The brokerage will not let you buy a fractional share unless you specifically choose that option (many brokerages now allow it). Calculate the total cost: number of shares times the price per share, plus any commission or fee the brokerage charges (most major brokerages charge zero commission on stock trades).

Placing your order and understanding order types

When you are ready to buy, you enter an order in your brokerage account. The most common order type for beginners is a market order, which buys the stock at whatever the current market price is, immediately. You specify the number of shares, confirm the total cost, and submit. The order executes within seconds during market hours (9:30 a.m. to 4 p.m. Eastern Time on weekdays when the stock market is open).

A limit order lets you set a maximum price you are willing to pay. If you want to buy a stock trading at $100 but only if it drops to $95, you place a limit order at $95. The order sits in the system and executes only if the price reaches your limit. Limit orders can take hours, days, or never execute if the price never reaches your target.

For your first purchase, a market order is simpler and more predictable. You know the order will go through immediately at the current price. Limit orders are useful once you understand how they work and have a specific price target in mind.

What happens after you buy: settlement and ownership

When your order executes, the money is deducted from your account immediately. However, the shares do not officially become yours until settlement — the process where the brokerage and the stock exchange confirm the trade and transfer ownership. Settlement takes one to three business days depending on the brokerage and the type of security. Most brokerages settle trades in one to two business days.

During the settlement period, you own the shares, but they may not appear in your account or be available to sell. Once settlement is complete, the shares show in your account balance, and you can sell them anytime the market is open. You also own any dividends the company pays while you hold the stock, though dividend payments are separate from the stock price.

Your brokerage sends you a confirmation email or notification within your account showing the number of shares, the price you paid per share, the total cost, and the settlement date. Keep this record for your taxes — you will need it when you sell the stock to calculate your gain or loss.

Selling your stock and understanding the tax impact

To sell, you search the stock ticker in your account, enter the number of shares you want to sell, and choose a market or limit order just as you did when buying. The sale executes immediately (for a market order) or when your price target is reached (for a limit order). The proceeds go into your cash balance within one to three business days.

When you sell a stock for more than you paid, you have a capital gain. When you sell for less, you have a capital loss. Both are taxable events. If you held the stock for more than one year, the gain or loss is long-term and taxed at a lower rate than short-term gains (stocks held one year or less). You do not owe taxes until you sell — simply owning a stock that goes up in value is not a taxable event.

Your brokerage tracks all your trades and sends you a tax form (Form 1099-B) at the end of the year showing your gains and losses. You report this on your tax return. If you are new to investing, consult a tax professional or use tax software to understand how your trades affect your tax bill.

Costs and fees to watch for

Most major brokerages charge zero commission on stock trades, meaning you do not pay a per-trade fee. However, some costs still exist. If you place a limit order that never executes, there is no cost. If you trade frequently, some brokerages charge inactivity fees or require a minimum account balance. Read your brokerage's fee schedule before you open an account.

The biggest cost is usually the difference between the bid and ask price — the spread. When you buy, you pay the ask price (slightly higher). When you sell, you receive the bid price (slightly lower). This spread is how market makers profit and is built into every trade. For stocks with high trading volume (like Apple or Microsoft), the spread is tiny — often just a penny. For less-traded stocks, the spread can be wider, costing you more.

Some brokerages offer margin accounts, which let you borrow money to buy more stock than you have cash for. Margin is risky for beginners and comes with interest charges and the possibility of losing more than you invested. Start with a regular cash account where you can only spend money you have.

Common mistakes beginners make

The most common mistake is buying a stock without understanding the company or why you are buying it. A stock price that has gone up a lot recently is not a reason to buy — it may be overpriced. Conversely, a stock that has dropped sharply is not automatically a bargain. Do basic research: read the company's latest earnings report, understand what the business does, and know whether you are buying for long-term growth or short-term trading.

Another mistake is trading too frequently. Every time you buy and sell, you trigger a taxable event and pay the bid-ask spread. Frequent trading costs money and makes taxes complicated. Most successful investors buy stocks and hold them for years, not days or weeks.

A third mistake is investing money you cannot afford to lose. Stock prices go down as well as up. If you need the money in the next few years, stocks are risky. Keep emergency savings in a savings account, not in stocks.

Frequently Asked Questions

Can I buy stocks with very little money?

Yes. Most brokerages have no minimum account balance and no commission on trades. You can buy a single share of any stock, even if it costs $1,000 per share, because many brokerages now allow fractional shares. You can start with $10 or $100 if you want, though the smaller your account, the more the bid-ask spread and any fees will eat into your returns.

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

A stock is a single company. A mutual fund or exchange-traded fund (ETF) is a basket of many stocks bundled together. Buying a fund spreads your risk across many companies instead of betting on one. Funds are often better for beginners because they are more diversified, though they may have higher fees than individual stocks.

Can I lose more money than I invested?

If you buy stocks with cash in a regular account, 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. If you use margin (borrowed money), you can lose more than your initial investment, which is why margin is risky for beginners.

Do I have to pay taxes on stocks I do not sell?

No. You only owe taxes when you sell a stock and realize a gain or loss. Simply owning a stock that goes up in value is not a taxable event. However, if the stock pays a dividend, you owe taxes on the dividend in the year you receive it, even if you do not sell the stock.

How long does it take to see my money after I sell a stock?

The sale executes within seconds during market hours, but the cash settles in your account within one to three business days. Once it settles, you can withdraw it to your bank account, which usually takes another one to three business days depending on your bank.
