To invest in stocks, you need a brokerage account, some form of government-issued ID, your Social Security number, and enough money to buy at least one share (or a fractional share, which can be as little as $1 at many brokers). Beyond those basics, a few financial foundations and decisions will set you up to invest without putting yourself in a tight spot.
What a Broker Asks For When You Open an Account
Every brokerage is required by law to collect certain personal and financial information before letting you trade. You’ll typically provide your name, date of birth, Social Security number (or taxpayer identification number), address, phone number, and email. You’ll also need a government-issued ID such as a driver’s license or passport.
Beyond the identity basics, the broker will ask about your finances and investing profile. Expect questions about your annual income, net worth, employment status, investment experience, risk tolerance, investment objectives, time horizon, and liquidity needs (how soon you might need the money back). These questions aren’t optional; brokers use them to comply with regulations and to flag situations where a particular investment might not be suitable for you. Answering honestly helps the broker and helps you. The entire application process is online at most brokers and takes 10 to 15 minutes.
You must be at least 18 to open a brokerage account in your own name. If you’re younger, a parent or guardian can open a custodial account on your behalf.
Choosing Between a Brokerage Account and a Roth IRA
The two most common starting points for new investors are a standard taxable brokerage account and a Roth IRA. Which one fits depends on what the money is for.
A standard brokerage account has no contribution limits and no restrictions on when you can withdraw. You can put in as much as you want and pull money out at any age without penalties. The trade-off is taxes: you’ll owe capital gains tax when you sell investments at a profit, and dividends are taxed in the year you receive them.
A Roth IRA is a retirement account. You contribute money you’ve already paid income tax on, but your investments grow tax-free, and qualified withdrawals in retirement are also tax-free. That’s a significant advantage over decades of compounding. The catch is that contributions are capped each year, income limits restrict who can contribute, and pulling out earnings before retirement can trigger taxes and penalties. If your goal is long-term retirement savings, a Roth IRA is often the better first account. If you want flexibility to use the money for any purpose at any time, a taxable brokerage account is the simpler choice. Many investors eventually use both.
How Much Money You Actually Need
Most major online brokers have no account minimum, meaning you can open an account with $0 and deposit money when you’re ready. Commission-free stock trading is now standard at the largest brokers, so buying and selling individual stocks or exchange-traded funds (ETFs) won’t cost you a per-trade fee.
The real question is how much you need to buy something. If you want a single share of a company trading at $150, you need $150. But many brokers now offer fractional shares, letting you buy a slice of a stock for as little as $1 or $5. This means you can start investing with very small amounts and build up over time. A common approach for beginners is to set up automatic recurring purchases of a broad-market ETF, even if it’s just $25 or $50 per paycheck.
Get Your Financial Foundation Right First
Investing while carrying high-interest debt or having no cash cushion can backfire. Stock prices fluctuate, and if an emergency forces you to sell at a loss because you have no savings to fall back on, you’ve turned a temporary dip into a permanent one.
Before directing money into the market, take care of three things. First, build an emergency fund, typically three to six months of essential expenses in a savings account. Second, pay off credit card debt and any other debt with an interest rate of 6% or higher. Paying down a credit card charging 22% gives you a guaranteed 22% “return” on that money, which the stock market won’t reliably match. Third, if your employer offers a retirement plan with a matching contribution, contribute enough to capture the full match. That’s free money with an immediate 50% or 100% return, depending on the match formula.
Once those boxes are checked, additional dollars you invest in stocks have a much better chance of staying invested long enough to grow.
Deciding What to Buy
New investors generally choose between individual stocks and funds. Individual stocks let you own a piece of a single company. The potential reward is high, but so is the risk: one company can drop 30% or more in a bad quarter. Funds spread your money across dozens or hundreds of companies at once, which reduces that concentration risk considerably.
The two main fund types you’ll encounter are mutual funds and ETFs. Both hold baskets of stocks, but ETFs trade throughout the day like a stock and typically have lower expense ratios (the annual fee the fund charges, expressed as a percentage of your investment). A broad-market index ETF that tracks the S&P 500 or the total U.S. stock market is one of the most popular starting points. You get instant diversification across hundreds of large companies, and annual fees on these funds are often below 0.10%, meaning you’d pay less than $1 per year for every $1,000 invested.
When you’re just starting out, a single broad-market index fund is a perfectly reasonable entire portfolio. You can add complexity later as you learn more and your account grows.
Understanding the Tax Side
In a taxable brokerage account, your broker will send you tax forms each year reporting what happened in the account. If you sold any stocks or funds, you’ll receive a Form 1099-B showing proceeds and cost basis for each sale. If you earned dividends, you’ll get a Form 1099-DIV. Many brokers consolidate these into a single year-end statement.
Short-term capital gains (profits on investments held one year or less) are taxed at your ordinary income tax rate. Long-term capital gains (investments held longer than one year) get a lower tax rate, which for most people is 0% or 15%. This is one of the strongest arguments for buying and holding rather than trading frequently. In a Roth IRA, none of this matters while the money stays in the account, because growth and qualified withdrawals are tax-free.
Placing Your First Trade
Once your account is funded, buying a stock or ETF takes about 30 seconds. You’ll search for the ticker symbol (a short abbreviation like AAPL for Apple or VOO for the Vanguard S&P 500 ETF), enter the number of shares or the dollar amount you want to invest, and choose an order type. A market order buys at whatever the current price is. A limit order lets you set a maximum price you’re willing to pay, and the trade only goes through if the stock hits that price or lower. For most beginners buying well-known stocks or ETFs during regular market hours (9:30 a.m. to 4:00 p.m. Eastern), a market order works fine.
After you confirm, the trade settles in one business day, meaning the shares officially land in your account the next business day. From that point on, you own a small piece of whatever you bought, and its value in your account will move up and down with the market. The single most important thing new investors can do is resist the urge to check the price constantly and sell at the first dip. Historically, the U.S. stock market has rewarded patience far more than frequent trading.
