How to Start Investing in the Stock Market

The basic steps to buy your first stock

To invest in the stock market, you open an account with a brokerage firm, deposit money, and then place orders to buy shares of individual companies or funds. The brokerage holds your money and executes the trades — buying and selling — on your behalf. You do not need a large sum to start; many brokerages accept initial deposits of $0 to $500, though some have no minimum at all.

The process itself takes about 15 to 30 minutes to set up. You will provide your name, Social Security number, address, employment information, and banking details so the brokerage can move money in and out of your account. After your account is approved (usually within one business day), you can fund it and begin placing orders when ready.

Most people do not buy individual stocks one at a time. Instead, they buy mutual funds or exchange-traded funds (ETFs), which are baskets of many stocks bundled together. This spreads your money across dozens or hundreds of companies, so a drop in one company's price does not wipe out your investment.

Key Takeaways

• You need a brokerage account to buy stocks, which you open online in minutes by providing your name, Social Security number, and bank account details.
• Most beginners buy mutual funds or ETFs instead of individual stocks because they own pieces of many companies at once, reducing risk.
• Your money sits in the brokerage account until you decide to buy; you control when to invest and what to invest in.
• Fees vary by brokerage — some charge nothing to buy stocks or funds, while others charge per trade or take a percentage of your account balance.
• You pay taxes on profits when you sell, and the tax rate depends on how long you held the investment and your income level.

Choosing a brokerage and opening an account

A brokerage is a company licensed to buy and sell securities on your behalf. Common brokerages include Fidelity, Vanguard, Charles Schwab, E*TRADE, and Robinhood. Each one has a website and a mobile app where you can manage your account.

When you compare brokerages, look at three things: the minimum deposit (if any), the fees they charge per trade, and whether they offer the types of investments you want. Some brokerages specialize in stocks, others in bonds, and some offer both. Many now charge zero dollars per stock trade, but may charge for certain mutual funds or advisory services.

To open an account, go to the brokerage's website and click "Open an Account" or similar. You will answer questions about your name, address, date of birth, employment, and income. The brokerage will ask whether you are opening an individual account, a joint account with a spouse, or a retirement account (like an IRA). For your first investment, an individual account is the simplest. The brokerage will verify your identity using your Social Security number and may check your credit, though this does not affect your credit score.

Once approved, you link your bank account so you can transfer money in. This usually takes one to three business days. Some brokerages let you start trading before the transfer clears, using a small amount of credit they extend to you.

Understanding stocks, funds, and what you are actually buying

A stock is a small piece of ownership in a company. If you buy one share of Apple, you own a tiny fraction of Apple. If the company does well and its stock price rises, your share is worth more. If the company struggles and the price falls, your share is worth less. Companies also sometimes pay dividends — small cash payments to shareholders — though not all do.

A mutual fund is a pool of money from many investors, managed by a professional who buys and sells stocks and bonds on everyone's behalf. When you buy one share of a mutual fund, you own a piece of everything inside it. If the fund holds 100 different stocks, your money is spread across all 100. The fund manager charges a fee (called an expense ratio) for managing it, usually between 0.05% and 1% per year.

An exchange-traded fund (ETF) works similarly to a mutual fund but trades like a stock — you can buy and sell it any time the market is open, and the price changes throughout the day. Mutual funds only trade once per day, after the market closes. ETFs often have lower fees than mutual funds and are popular with beginners.

For someone starting out, an ETF that tracks a broad market index — like the S&P 500 (which holds 500 large U.S. companies) or the total stock market — is a common first choice. You buy one ETF and own pieces of hundreds of companies without having to pick individual stocks.

How to place your first trade

Once your account is funded, you log in to your brokerage and look for a "Buy" or "Trade" button. You will enter the ticker symbol (a short code for the stock or fund — for example, "SPY" for an S&P 500 ETF) and the number of shares you want to buy. The brokerage will show you the current price and calculate the total cost.

You then choose the type of order. A market order buys when ready at whatever the current price is. A limit order lets you set a maximum price you are willing to pay; if the price drops to that level, the order fills automatically, but if it never reaches that price, the order stays open until you cancel it. For most beginners, a market order is simpler.

After you review the details, you click "Confirm" or "Submit," and the trade executes within seconds. The shares appear in your account, and your cash balance drops by the amount you spent. You now own the investment.

You can check your account balance and the current value of your holdings anytime by logging in. The value will go up and down as market prices change. You do not have to do anything — your investment sits there until you decide to sell.

Understanding fees and costs

Fees are what the brokerage charges you for the service of holding your account and executing trades. The structure varies widely.

Per-trade commissions: Some brokerages charge a flat fee (like $5 or $10) each time you buy or sell. This is becoming less common; many major brokerages now charge zero commission on stock and ETF trades.

Expense ratios: If you buy a mutual fund or ETF, the fund itself charges an annual fee, expressed as a percentage of your account balance. A 0.05% expense ratio on a $10,000 investment costs $5 per year. A 1% ratio on the same $10,000 costs $100 per year. The fee is deducted automatically; you do not pay it separately.

Account maintenance fees: Some brokerages charge an annual fee to hold an account, though many waive this if you maintain a minimum balance or set up automatic deposits.

Advisory fees: If you use a robo-advisor (an automated service that builds and manages a portfolio for you), you typically pay 0.25% to 0.50% of your account balance per year.

When you are comparing brokerages, add up the total cost: commission per trade plus the expense ratio of the funds you plan to buy. A brokerage with zero commissions but high-fee funds may cost more than one with small commissions and low-fee funds.

Taxes on investment gains and losses

When you sell an investment for more than you paid for it, you have a capital gain, and you owe federal income tax on that profit. The tax rate depends on how long you held the investment.

If you held it for one year or less, it is a short-term capital gain, taxed at your ordinary income tax rate (which can be 10%, 12%, 22%, 24%, 32%, 35%, or 37%, depending on your income). If you held it for more than one year, it is a long-term capital gain, taxed at a lower rate: 0%, 15%, or 20%, depending on your income.

If you sell for less than you paid, you have a capital loss, which can offset capital gains. If your losses exceed your gains in a year, you can deduct up to $3,000 of the loss against your ordinary income, and carry forward any remaining loss to future years.

Your brokerage will send you a tax form (Form 1099-B) in January showing all your trades from the previous year. You report this information on your tax return. If you use tax software like TurboTax or TaxAct, you can usually import this data directly.

Dividends are also taxable. may have access to dividends (from U.S. companies, held for at least 60 days around the payment date) are taxed at the long-term capital gains rate. Non-may have access to dividends are taxed as ordinary income.

Common mistakes to avoid

Trying to time the market — buying low and selling high — is extremely difficult even for professionals. Most beginners lose money trying. A better approach is to invest regularly (like $200 per month) regardless of price, so you buy more shares when prices are low and fewer when they are high. This is called dollar-cost averaging.

Putting all your money into one stock or sector is risky. If that company or industry struggles, your entire investment suffers. Spreading money across many stocks (through a fund) reduces this risk.

Paying high fees without realizing it is common. Before you invest, calculate the total annual cost: commissions plus expense ratios. A difference of 0.5% per year may not sound like much, but over 20 years it can mean tens of thousands of dollars in lost growth.

Selling in a panic when the market drops is another costly mistake. Markets go down regularly, but historically they have recovered and reached new highs. Selling during a downturn locks in your loss. If you have a long time horizon (10+ years), staying invested through downturns is usually the better choice.

Retirement accounts versus regular investment accounts

A regular brokerage account (called a taxable account) has no restrictions. You can buy, sell, and withdraw money anytime without penalty. You pay taxes on gains and dividends each year.

A retirement account, like a traditional IRA or Roth IRA, has tax advantages but restrictions. With a traditional IRA, you may deduct your contributions from your taxes, and you do not pay taxes on gains until you withdraw money in retirement. With a Roth IRA, you contribute after-tax money, but withdrawals in retirement are tax-free. Both have annual contribution limits (for 2024, the limit is $7,000 if you are under 50) and penalties if you withdraw before age 59½.

If your employer offers a 401(k), that is another retirement account. You contribute pre-tax money, and your employer may match a portion of your contribution. The money grows tax-deferred until retirement.

For most beginners, starting with a regular taxable account is simpler because there are no restrictions. Once you understand investing better, you can open a retirement account to take advantage of the tax benefits.

Frequently Asked Questions

How much money do I need to start investing?

Many brokerages have no minimum deposit. You can open an account with $1 and buy fractional shares (pieces of a share) if a stock is expensive. However, starting with at least $100 to $500 makes it easier to see the impact of your investment and to build a diversified portfolio across multiple funds.

Can I lose more money than I invested?

In a regular brokerage account, no. The worst that can happen is your investment goes to zero. However, if you use margin (borrowed money) to invest, you can lose more than you put in. As a beginner, avoid margin.

Should I pick individual stocks or buy funds?

Most beginners should start with funds (mutual funds or ETFs) because they own many companies at once, reducing risk. Picking individual stocks requires research and carries higher risk. Once you have experience and understand how companies work, you can add individual stocks if you want.

When should I sell an investment?

Sell when your circumstances change — you need the money, your goals shift, or the investment no longer fits your plan. Avoid selling just because the price dropped or because you think it will drop further. If you are investing for retirement (10+ years away), hold through market ups and downs.

Do I need a financial advisor to invest?

No. You can learn to invest on your own using online resources, books, and your brokerage's educational materials. A financial advisor can be helpful if you have complex finances or prefer professional guidance, but they charge fees that reduce your returns. Start on your own, and consider an advisor later if needed.
