Investing in the stock market starts with three steps: opening a brokerage account, funding it, and buying your first investment. Every major online broker now charges $0 per trade and requires no minimum deposit, so the barriers that once kept people out are essentially gone. What matters more than the mechanics is understanding the choices you’ll make along the way, from the type of account you open to the investments you pick and the taxes you’ll eventually owe.
Pick the Right Account Type
Before you buy a single share, you need somewhere to hold it. The two main options are a standard brokerage account and a retirement account like an IRA. Your choice affects how much you can invest and how your gains are taxed.
A standard brokerage account lets you buy and sell investments freely with no contribution limits and no income restrictions. The tradeoff is that you’ll owe taxes on dividends and capital gains each year. This is the right pick if you want flexibility to withdraw money whenever you need it, or if you’ve already maxed out your retirement accounts.
A Roth IRA is funded with money you’ve already paid taxes on, but qualified withdrawals in retirement are completely tax-free. It has annual contribution limits and income caps that may restrict how much you can put in. The upside is powerful: decades of investment growth that you’ll never owe taxes on. Roth IRAs also have no required minimum distributions, so you’re not forced to pull money out at a certain age.
A traditional IRA (or a 401(k) through your employer) works in reverse. Contributions may lower your taxable income now, but you’ll pay income tax on withdrawals in retirement. If you expect to be in a lower tax bracket later, that trade can work in your favor.
Many investors open both a retirement account and a brokerage account. The retirement account shelters long-term growth from taxes, while the brokerage account gives you unrestricted access to your money.
Open and Fund a Brokerage Account
Opening an account takes about 10 to 15 minutes online. You’ll need your Social Security number, a government-issued ID, and a bank account to link for transfers. Every major platform, including Fidelity, Charles Schwab, Vanguard, Robinhood, and E*TRADE, charges $0 for online stock and ETF trades and requires no minimum deposit to get started.
When choosing a broker, look at a few practical differences. Some platforms offer fractional shares, which let you buy a slice of an expensive stock for as little as $1 or $5. That’s useful if you want to own shares of companies trading at hundreds of dollars per share but don’t want to commit that much at once. Not every broker offers this feature, so check before you sign up. Also compare the platform’s research tools, mobile app quality, and the range of account types available (brokerage, Roth IRA, traditional IRA, etc.).
Once the account is open, transfer money from your bank. Most brokers process electronic transfers in one to three business days, though some let you trade immediately while the transfer settles.
Choose Between Index Funds and Individual Stocks
This is the decision that will shape your returns more than almost anything else. You have two broad paths: buying index funds (or ETFs) that hold hundreds of stocks at once, or picking individual company stocks yourself.
Index funds track a market index like the S&P 500, giving you instant diversification across many companies in a single purchase. If one company in the fund drops 50%, the impact on your portfolio is small because it’s spread across hundreds of holdings. Fees on index funds are typically very low, often a fraction of a percent per year. For most people, especially those just starting out, index funds are the simplest path to long-term growth without needing to research individual companies.
Individual stocks let you invest directly in companies you believe will perform well. The potential upside is higher, but so is the risk. A single stock can lose a significant chunk of its value on one bad earnings report. Individual stock picking also requires more active attention: reading financial statements, following industry news, and monitoring your positions. If you go this route, treat individual stocks as the speculative portion of your portfolio and invest only money you can afford to lose. The core of your portfolio is generally better served by diversified funds.
A practical approach many investors use is putting 80% to 90% of their money into broad index funds and using the remaining 10% to 20% for individual stocks they’ve researched and believe in.
Understand Order Types Before You Buy
When you’re ready to place your first trade, your broker will ask what type of order you want. The three most common are market orders, limit orders, and stop orders.
A market order buys or sells at the best price currently available. It executes almost instantly during market hours, but the exact price you get may shift slightly between the moment you click “buy” and the moment the trade fills. For most beginners buying well-known stocks or ETFs, a market order is perfectly fine.
A limit order lets you set the maximum price you’re willing to pay (when buying) or the minimum price you’ll accept (when selling). The trade only goes through at your specified price or better. This is useful when a stock’s price is moving quickly and you want to avoid overpaying. The risk is that if the price never reaches your limit, your order won’t execute at all.
A stop order, sometimes called a stop-loss, triggers a sale when a stock drops to a price you specify. For example, if you buy a stock at $50 and set a stop order at $45, your shares will automatically be sold if the price falls to $45. This helps limit losses on a position without requiring you to watch it constantly. Stop orders can also be used to protect gains: if your $50 stock rises to $75, you could move your stop to $65 to lock in some profit.
Decide How Much and How Often to Invest
You don’t need a large sum to start. Many brokers allow purchases as small as $1 through fractional shares. What matters more than the starting amount is consistency. Investing a fixed dollar amount on a regular schedule, say $100 or $500 every month, is a strategy called dollar-cost averaging. When prices are high, your fixed amount buys fewer shares. When prices drop, it buys more. Over time, this smooths out the effect of market volatility and removes the pressure of trying to time your purchases perfectly.
How much of your income to invest depends on your financial situation. A common starting target is 10% to 15% of your gross income, but even smaller amounts build meaningful wealth over decades thanks to compounding. The key is to invest consistently and increase your contributions as your income grows.
Know the Tax Rules on Your Gains
If you’re investing in a standard brokerage account, the taxes you owe depend on how long you held an investment before selling.
Short-term capital gains apply to investments held for one year or less. These are taxed at your ordinary income tax rate, which can be as high as 37% depending on your bracket. This is why flipping stocks quickly can eat into your returns.
Long-term capital gains apply to investments held for more than one year, and the rates are significantly lower. For 2026, single filers with taxable income up to $49,450 pay 0% on long-term gains. The 15% rate covers income from $49,451 to $545,500, and the 20% rate applies above that. Married couples filing jointly get roughly double those thresholds. High earners may also owe an additional 3.8% net investment income tax on top of those rates.
The practical takeaway: holding investments for at least a year before selling can save you a substantial amount in taxes. In a Roth IRA, this is a non-issue since qualified withdrawals are tax-free. In a traditional IRA or 401(k), you won’t owe capital gains taxes either, but you’ll pay ordinary income tax when you withdraw in retirement.
Dividends paid by your investments are also taxable in a brokerage account. Most dividends from U.S. stocks are taxed at the lower long-term capital gains rates, but some are taxed as ordinary income. Your broker will send you a tax form each year that breaks this down.
Build a Strategy You’ll Stick With
The biggest risk for new investors isn’t picking the wrong stock. It’s reacting emotionally to market drops. The S&P 500 has historically delivered average annual returns near 10% over long periods, but in any given year it can swing dramatically in either direction. Selling during a downturn locks in losses and means you miss the recovery.
Set your investment plan based on your timeline. Money you’ll need within the next one to three years belongs in something safer, like a high-yield savings account or short-term bonds. Money you won’t touch for five years or more has time to ride out market swings and is better suited for stock investments. The longer your time horizon, the more volatility you can absorb.
Revisit your portfolio once or twice a year to make sure your mix of investments still matches your goals. If one holding has grown to dominate your portfolio, rebalancing by selling some of it and buying other assets brings you back to your target allocation. Beyond that, the best thing most investors can do is keep contributing regularly and resist the urge to check their balance every day.
