To invest in a stock, you open a brokerage account, deposit money, search for the company you want to buy, and place an order. The entire process can take less than an hour if you already have your basic personal information handy, and most major brokerages charge $0 per trade with no account minimum. Here’s how each step works in practice.
Open a Brokerage Account
A brokerage account is your gateway to the stock market. It works like a bank account, but instead of just holding cash, it lets you buy and sell stocks, ETFs, and other investments. You can open one online in about 10 to 15 minutes.
During the signup process, you’ll be asked to provide your Social Security number (brokerages report your investment income to the IRS), your date of birth, employment status, and some basic financial details like your income range, net worth, and investment experience. This information helps the brokerage understand your financial situation and is required by federal regulations. You’ll also need a valid government ID and a bank account to link for transfers.
Several well-known brokerages, including Fidelity, Charles Schwab, and Interactive Brokers, have no account minimum and charge $0 per online stock trade. Smaller platforms like SoFi and Public offer the same zero-commission, zero-minimum structure. The lack of fees means every dollar you deposit goes directly toward your investment.
Choose the Right Account Type
Before you fund your account, decide whether you want a standard taxable brokerage account or a tax-advantaged retirement account like a Roth IRA. The choice affects how much you keep after taxes.
With a standard brokerage account, you can buy and sell freely with no withdrawal restrictions, but you’ll owe taxes on dividends, interest, and any profits when you sell a stock at a gain. Those profits are taxed as capital gains: a lower rate if you held the stock for more than a year, and your regular income tax rate if you held it for a year or less.
A Roth IRA, by contrast, lets your investments grow tax-free. You contribute money you’ve already paid income tax on, but qualified withdrawals in retirement come out without any additional tax. The tradeoff is that Roth IRAs have annual contribution limits and income caps, and pulling money out early can trigger penalties. If you’re investing for retirement and qualify, a Roth IRA saves you money over the long run. If you want flexible access to your cash with no restrictions on when you can withdraw, a taxable brokerage account is the simpler choice.
Fund Your Account
Once your account is open, link your checking or savings account and transfer money in. Most brokerages process electronic transfers within one to three business days, though some offer instant access to a portion of your deposit so you can start trading right away.
You don’t need thousands of dollars to get started. Many brokerages now offer fractional shares, which let you buy a piece of a stock rather than a whole share. Charles Schwab, for instance, lets you purchase slices of S&P 500 stocks for as little as $5 each. Fidelity, Interactive Brokers, SoFi, and Public all support fractional share trading at $0 commission. So if a stock trades at $400 per share but you only have $50 to invest, you can still own a fraction of that company.
Research Before You Buy
Picking a stock means forming a view on whether the company is worth owning at its current price. Most investors rely on one of two approaches, or a combination of both.
Fundamental analysis looks at the company itself. You review its financial statements (income statement, balance sheet, and cash flow statement) to understand whether it’s profitable, how much debt it carries, and whether it’s generating real cash. Ratios help you compare companies quickly. The price-to-earnings ratio, or P/E, tells you how much investors are paying for each dollar of the company’s earnings. A high P/E might mean the market expects strong future growth, while a low P/E could signal a bargain or a struggling business. You’ll also want to look at the broader picture: how the overall economy is performing, what interest rates are doing, and whether the company’s industry is growing or shrinking.
Technical analysis takes a different angle. Instead of studying the business, it studies the stock’s price history and trading volume to spot patterns that might predict where the price goes next. Traders who use this approach look at price charts and statistical indicators to identify trends. Technical analysis is more common among short-term traders, while fundamental analysis tends to guide long-term investors.
If this feels overwhelming, many beginners start with companies whose products they know and use, then dig into the financials from there. Your brokerage platform will have a research section for every stock, including analyst ratings, earnings data, and key financial ratios.
Place Your First Order
When you’re ready to buy, search for the stock by its company name or ticker symbol (the short abbreviation used on stock exchanges, like AAPL for Apple). Then choose the type of order you want to place.
Market order: This buys the stock immediately at whatever the current price is. It guarantees your order goes through, but the exact price you pay might shift slightly between the moment you click “buy” and the moment the trade executes. For most beginners buying well-known stocks during regular market hours, that difference is usually pennies.
Limit order: This lets you set the maximum price you’re willing to pay. If you want shares of a company but only at $50 or less, a buy limit order will only execute if the stock drops to $50 or below. The upside is price control. The downside is your order might never fill if the stock doesn’t reach your target price.
Stop order: Also called a stop-loss order, this is mainly used after you already own a stock. You set a trigger price below the current market price, and if the stock falls to that level, your stop order automatically converts into a market order and sells your shares. It’s a way to limit losses if a stock drops sharply while you’re not watching.
For your first trade, a market order is the most straightforward. Select the number of shares (or dollar amount, if your brokerage supports fractional shares), review the order summary, and confirm. During regular U.S. market hours, 9:30 a.m. to 4:00 p.m. Eastern time on weekdays, a market order typically executes within seconds.
What Happens After You Buy
Once your order fills, the shares appear in your account. You now own a small piece of that company. If the company pays dividends (periodic cash payments to shareholders), those will show up in your account automatically, usually quarterly. You can choose to reinvest dividends into more shares or let the cash accumulate.
Your brokerage will show you real-time or slightly delayed updates on your stock’s price, your total portfolio value, and your gain or loss on each position. Keep in mind that daily price swings are normal. Stocks can move several percentage points in either direction on any given day, and that volatility tends to smooth out over longer holding periods.
When you eventually sell, the process mirrors buying: search for the stock, select “sell,” choose your order type, and confirm. In a taxable brokerage account, any profit from the sale becomes a capital gain that you’ll report on your tax return for that year. In a Roth IRA, no tax is owed on the gain as long as you follow the withdrawal rules.
Starting Simple
If picking individual stocks feels like too much too soon, consider starting with an index fund or ETF (exchange-traded fund). These are baskets of stocks bundled into a single investment. An S&P 500 index fund, for example, gives you exposure to 500 of the largest U.S. companies in one purchase. You buy and sell ETFs through your brokerage account exactly the same way you’d buy a stock, and they provide built-in diversification so your results don’t hinge on one company’s performance. Many investors hold a mix of individual stocks and index funds, adjusting the balance as they gain experience and confidence.
