You need a brokerage account, money to invest, and a decision about what stocks to buy

Buying stock means purchasing a small ownership stake in a company. To do it, you open an account with a brokerage firm (an organization licensed to buy and sell securities), deposit money, and place an order for the shares you want. The brokerage executes the trade, holds your shares, and sends you statements showing what you own and what it is worth.

The actual mechanics are straightforward — most brokerages let you place an order in minutes through a website or app. The harder part is deciding how much money to risk, which stocks or funds to buy, and whether you are prepared for the value to drop before it rises. Stock prices move constantly based on company performance, economic conditions, and investor sentiment. You can lose money if you sell when the price is down.

Key Takeaways

  • Opening a brokerage account requires choosing a firm, providing identification and tax information, and linking a bank account to fund it.
  • You can buy individual stocks, but most new investors start with index funds or exchange-traded funds (ETFs) that hold many stocks at once, reducing risk from any single company failing.
  • The money you invest should be money you do not need for at least three to five years, because short-term stock price swings can force you to sell at a loss.
  • Commissions and fees vary by brokerage; many charge zero commission per trade, but all charge account maintenance fees or require a minimum balance.
  • Your brokerage will send you tax documents each year (Form 1099-B) showing your gains and losses, which you report on your tax return.

Choosing a brokerage and opening an account

A brokerage is a licensed firm that holds your money and executes your trades. Common brokerages include Fidelity, Charles Schwab, E*TRADE, Interactive Brokers, and Robinhood. Each has different fee structures, minimum account balances, research tools, and customer service options. Many charge no commission per trade, but some require a minimum deposit (often $500 to $2,500) to open an account, and some charge monthly maintenance fees if your balance falls below a threshold.

To open an account, you will provide your name, address, Social Security number, employment information, and bank details. The brokerage verifies your identity and runs a background check. You then link a bank account so you can transfer money in. This process usually takes one to three business days. Once your account is funded, you can place your first trade immediately.

Before choosing a brokerage, compare their fee structure, minimum balance requirements, and whether they offer the types of investments you want (individual stocks, mutual funds, ETFs, bonds, options). Read reviews from current users, not just marketing materials. Many brokerages offer paper trading — a practice account with fake money — so you can learn how to place orders without risking real funds.

Individual stocks versus funds: which to buy

An individual stock is a share in one company. If you buy 10 shares of Apple, you own a tiny piece of Apple. The price moves based on how well Apple performs and what investors think Apple is worth. If Apple does well, the stock price rises and you make money. If Apple struggles, the price falls and you lose money.

A fund is a collection of many stocks (or bonds, or both) bundled together. An index fund tracks a specific group — for example, the S&P 500 index fund holds stock in 500 large U.S. companies. An exchange-traded fund (ETF) works the same way but trades like a stock throughout the day. If you buy one share of an S&P 500 ETF, you own a tiny piece of all 500 companies at once. If one company fails, the impact on your investment is small because you own 499 others.

New investors usually benefit from starting with funds rather than individual stocks. Funds spread your risk across many companies, so a single bad decision does not wipe out your money. They also require less research — you do not have to study individual companies. Individual stocks demand more time and knowledge; if you pick wrong, you can lose a significant portion of your investment. Many experienced investors use a mix of both.

How much money you need to start

There is no legal minimum to open a brokerage account, but your brokerage may require a minimum deposit to fund it. This ranges from zero to $2,500 depending on the firm. Some brokerages waive the minimum if you set up automatic monthly deposits.

The amount you invest should come from money you will not need for at least three to five years. Stock prices fluctuate daily. If you need the money in six months and the market drops 20 percent, you may have to sell at a loss. Money you need for an emergency fund, upcoming home down payment, or next year's car purchase should stay in a savings account, not in stocks.

You can start with a small amount — $100, $500, or $1,000 — and add more over time. Many investors use automatic transfers, depositing a fixed amount each month. This approach, called dollar-cost averaging, means you buy more shares when prices are low and fewer when prices are high, which can reduce the impact of poor timing.

Placing your first trade

Once your account is open and funded, you log into your brokerage's website or app and navigate to the trading section. You search for the stock or fund you want to buy by its ticker symbol (a short code — for example, AAPL for Apple, VOO for Vanguard S&P 500 ETF). You enter the number of shares you want and review the order details: the price per share, the total cost, and any fees.

You then submit the order. Most orders are "market orders," which execute immediately at the current market price. Some investors use "limit orders," which only execute if the price drops to a specific level you set. Market orders are simpler for beginners; limit orders give you more control but may not execute if the price never reaches your limit.

After the trade executes, the shares appear in your account. You now own them. You can hold them indefinitely, sell them anytime the market is open (9:30 a.m. to 4 p.m. Eastern time on weekdays), or add to your position by buying more shares later.

Understanding fees and taxes

Most brokerages charge zero commission per trade, meaning you do not pay a fee when you buy or sell. However, some charge account maintenance fees (usually $0 to $20 per month) if your balance is below a minimum, or inactivity fees if you do not trade for a set period. Read your brokerage's fee schedule before opening an account.

When you sell a stock for more than you paid, you have a capital gain, which is taxable income. If you hold the stock for more than one year before selling, it is taxed at the long-term capital gains rate, which is lower than the short-term rate (for stocks held one year or less). Your brokerage sends you a Form 1099-B each January showing all your trades and gains or losses from the previous year. You report this on your tax return.

Dividends — payments some companies make to shareholders — are also taxable. Your brokerage reports these on a Form 1099-DIV. If you hold stocks in a tax-advantaged retirement account like a 401(k) or IRA, you do not pay taxes on gains or dividends until you withdraw the money (or in some cases, never, depending on the account type).

Managing risk and avoiding common mistakes

The biggest mistake new investors make is investing money they will need soon, then panicking and selling when the market drops. Stock markets go down regularly — sometimes 10 to 20 percent in a year — and recover over time. If you cannot afford to wait out a downturn, stocks are not the right place for that money.

Another common mistake is buying individual stocks based on tips from friends, social media, or news headlines without doing your own research. Stock prices can be driven by hype rather than company fundamentals. By the time you hear about a "hot stock," the price may already be inflated, and you may be buying at the peak.

Overtrading — buying and selling frequently — costs you money in taxes and can lead to emotional decisions. Most research shows that investors who buy and hold a diversified portfolio of low-cost index funds outperform those who trade frequently. Start simple: pick a fund or a small group of funds, invest regularly, and review your portfolio once or twice a year.

Frequently Asked Questions

Can I lose more money than I invest?

If you buy stocks with cash, no — the worst case is the stock goes to zero and you lose your entire investment. If you use margin (borrowed money from your brokerage), you can lose more than you invested. Beginners should avoid margin until they understand how it works.

What is the difference between a stock and a bond?

A stock is ownership in a company; a bond is a loan you make to a company or government. Bonds are generally less risky but offer lower returns. Many investors hold both to balance risk and reward.

Do I have to pick individual stocks or can I just buy funds?

You can build an entire portfolio with only funds. Many successful long-term investors do. Funds are simpler, require less research, and reduce the risk of picking a bad individual stock.

How often should I check my account?

Checking daily can lead to emotional decisions based on short-term price swings. Most advisors recommend reviewing your portfolio quarterly or annually to rebalance if needed, but not obsessing over daily changes.

What happens if my brokerage goes out of business?

Your stocks and cash are protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 per account if a brokerage fails. This is separate from FDIC bank insurance, so your investments are safeguarded even if the brokerage collapses.
