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

Buying stocks means purchasing shares of ownership in a company. To do it, you open an account with a brokerage — a company that buys and sells stocks on your behalf. You fund that account with money, then use it to place orders for the stocks you want. The brokerage executes the trade, holds your shares, and sends you statements showing what you own.

The process takes about 15 minutes to set up, but the decision about which stocks to buy takes longer. Most people either pick individual companies they believe in, or buy funds that hold many stocks at once. Both approaches work; they just carry different risks and require different amounts of research.

Key Takeaways

  • You open a brokerage account online, provide your Social Security number and bank details, and fund it before you can buy any stocks.
  • Individual stocks let you own a piece of one company, while funds let you own pieces of many companies with a single purchase.
  • Commissions and fees have largely disappeared, but account minimums and fund expense ratios still vary by brokerage.
  • Your first purchase can happen the same day you fund your account, but most investors wait to research what they are buying.
  • Stocks are riskier than savings accounts because their value changes daily, so only invest money you will not need for at least five years.

Opening a brokerage account

A brokerage account is straightforward a holding place for your money and your stocks. You open one online by visiting a brokerage website, entering your name, address, and Social Security number, and answering questions about your income and investment experience. The brokerage runs a background check and approves you within minutes or hours.

Common brokerages include Fidelity, Charles Schwab, E*TRADE, Robinhood, and Webull. Each one has a different website layout and different fees, but all of them let you buy stocks. Some charge no account minimum; others require $500 or $1,000 to start. Some offer free research tools; others charge for premium data. Compare a few before you choose, but do not let the choice paralyze you — you can always move your stocks to a different brokerage later.

After approval, you link a bank account and transfer money into your brokerage account. This usually takes one to three business days. Once the money arrives, you can place your first stock order.

Buying individual stocks versus stock funds

An individual stock is a share of one company. If you buy 10 shares of Apple, you own a tiny piece of Apple. If Apple does well, your shares become more valuable. If Apple struggles, they become less valuable. You pick which companies to buy based on your own research.

A stock fund is a collection of many stocks bundled together. You buy one fund and own pieces of 50, 100, or 500 different companies at once. The fund manager or an automated system decides which stocks go in the fund. Two common types are mutual funds (managed by a person or team) and exchange-traded funds, or ETFs (usually automated and cheaper to own). Most funds track an index like the S&P 500, which means they hold the same 500 large companies the index does.

Individual stocks require you to research companies, understand their finances, and decide when to buy and sell. Funds require less research because diversification — owning many companies — reduces the damage if one company fails. Most beginning investors start with funds because the risk is lower and the work is less.

Placing your first stock order

Once your account is funded, you log in to your brokerage website or app and search for the stock or fund you want to buy. The search bar will show you the ticker symbol (a short code like AAPL for Apple or SPY for an S&P 500 fund). Click on it and you will see the current price per share.

You then decide how many shares to buy. If a stock costs $150 per share and you have $1,500 to invest, you can buy 10 shares. Some brokerages now let you buy fractional shares, meaning you can spend exactly $1,500 and own 10 shares even if the price does not divide evenly. Enter the number of shares, review the total cost, and click "buy" or "place order."

The order executes almost when ready during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays). If you place an order after hours or on a weekend, it waits until the market opens the next trading day. Your brokerage then sends you a confirmation showing what you bought, how many shares, and the total cost.

Understanding costs and fees

Most brokerages no longer charge a commission — a fee per trade — when you buy or sell stocks. This is a major change from 10 years ago, when every trade cost $5 to $10. Today, buying a single share costs nothing in commissions.

However, some costs remain. Expense ratios are annual fees charged by funds. If a fund has a 0.03% expense ratio and you own $10,000 of it, you pay $3 per year. The fee is automatic and invisible — it comes out of the fund's value. Cheap index funds charge 0.03% to 0.10% per year. Actively managed funds often charge 0.50% to 1.50% or more. Over decades, this difference compounds significantly.

Some brokerages charge account maintenance fees or require minimum balances. Others offer free research, educational content, and customer support. Read the fee schedule on the brokerage website before you open an account, but do not assume the cheapest brokerage is the best — a $10 annual fee matters less than a 1% expense ratio on a fund you will own for 30 years.

Timing your purchases and managing risk

You can buy stocks any trading day, and there is no penalty for waiting. Many new investors make their first purchase, then wait weeks or months before buying again. Others set up automatic monthly purchases, which removes emotion from the decision and spreads your purchases across different prices over time.

Stock prices change every second the market is open. A stock you buy at $100 might be worth $95 tomorrow or $110. This volatility — the up-and-down movement — is why stocks are riskier than savings accounts. If you need the money in two years, a sudden drop could force you to sell at a loss. If you can leave the money alone for five, 10, or 30 years, short-term drops matter less because stocks historically recover and climb higher over long periods.

Only invest money you will not need soon. If you have credit card debt or no emergency fund, pay those down first. If you have stable income and three to six months of expenses saved, you are ready to start buying stocks.

What happens after you buy

Once you own stocks, your brokerage sends you quarterly or annual statements showing what you own, how many shares, the current value, and your total gain or loss. You can log in anytime to check prices, but most investors check infrequently — daily price checking often leads to panic selling when prices drop.

Some stocks pay dividends, which are small cash payments the company sends to shareholders. Your brokerage automatically deposits dividends into your account, and you can use that cash to buy more stocks or leave it sitting. Dividends are optional — many stocks do not pay them, and many funds hold a mix of dividend-paying and non-dividend-paying stocks.

You can sell your stocks anytime during market hours. Log in, find the stock or fund you own, enter how many shares to sell, and click "sell." The cash arrives in your brokerage account within one to three days, and you can then transfer it back to your bank account. There are no penalties for selling, though selling within a year of purchase may trigger higher taxes on your profit.

Common mistakes to avoid

The biggest mistake is buying stocks you do not understand. If you cannot explain in one sentence why you own a stock, you probably should not own it. Research the company, read its annual report, or choose a straightforward index fund instead.

The second mistake is trying to time the market — buying when you think prices are low and selling when you think they are high. Professional investors fail at this constantly. Instead, buy regularly over time and hold for years. This approach, called dollar-cost averaging, removes the pressure to predict the future.

The third mistake is borrowing money to buy stocks. Some brokerages let you borrow against your account to buy more stocks, a practice called margin. This amplifies both gains and losses. If the market drops 20%, your borrowed money means you lose 40%. Avoid margin until you have years of experience.

Frequently Asked Questions

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

Most brokerages have no minimum, so you can start with $100 or $1,000. Some brokerages require $500 or $1,000 to open an account. Fractional shares mean you can buy a piece of an expensive stock even if you have only $50. Start with whatever you can afford to leave invested for at least five years.

Can I lose more money than I invested?

If you buy individual stocks or funds with your own money (not borrowed), the worst that can happen is the stock goes to zero and you lose everything you invested. You cannot lose more than you put in. If you use margin (borrowed money), losses can exceed your initial investment, which is why margin is risky for beginners.

Should I pick individual stocks or buy a fund?

Funds are simpler and safer for most people because you own many companies at once. Individual stocks require research and carry more risk if you pick poorly. If you enjoy research and have time, individual stocks can work. If you want simplicity, a low-cost index fund is the better choice.

When should I sell my stocks?

Sell when you need the money or when your investment plan changes. Do not sell because the price dropped — that locks in a loss. Do not sell because the price rose — that triggers taxes. Most investors hold for years and sell only when their life circumstances change or they reach a specific financial goal.

Do I have to pay taxes on stocks I buy?

You pay taxes on profits when you sell. If you buy a stock for $100 and sell it for $150, you owe tax on the $50 gain. Dividends are also taxable. Tax rates depend on how long you held the stock and your income level. Keep records of what you bought, when, and for how much so you can calculate gains accurately at tax time.
