You need a brokerage account, money to invest, and a plan for what to buy

Investing in stocks means buying shares of ownership in companies. To do this, you open an account with a brokerage — a company that lets you buy and sell stocks on your behalf. You fund that account with your own money, then place orders to purchase specific stocks. The brokerage executes the trade and holds your shares until you decide to sell them.

The process itself takes about 15 minutes to set up. The harder part is deciding which brokerage to use, how much money to start with, and what stocks or funds to buy. This guide walks you through each decision and the real trade-offs involved.

Key Takeaways

  • Opening a brokerage account requires your Social Security number, proof of address, and a bank account to fund it, and takes one to three business days to set up.
  • You can start with any amount of money, but most brokerages have no minimum deposit, and some stocks cost less than $10 per share.
  • Buying individual stocks means researching companies yourself, while buying index funds or ETFs means owning hundreds of companies at once with less research required.
  • Stocks can lose value as well as gain it, and money you invest should be money you do not need for at least three to five years.
  • Your brokerage account is separate from your bank account, and you control when to move money in and out.

Choosing a brokerage and opening your account

A brokerage is a licensed company that holds your money and executes your trades. Common brokerages include Fidelity, Charles Schwab, E*TRADE, Robinhood, and Webull. Each charges different fees, offers different research tools, and has different account minimums — though most have no minimum at all now.

To open an account, you will need your Social Security number, a government-issued ID, proof of your current address (a utility bill or bank statement works), and a bank account to link for deposits. The brokerage will verify this information, which usually takes one to three business days. Once approved, you can log in and fund your account by transferring money from your bank.

The account itself is free to open. You pay fees only when you trade or if you hold certain types of investments. Most brokerages charge zero dollars per stock trade now, though some charge fees for mutual funds or if you trade very frequently. Read the fee schedule on the brokerage website before you open the account — it is usually listed under "Pricing" or "Fees".

How much money you need to start

There is no legal minimum. You can open an account with $1 and buy fractional shares — meaning you own a piece of a stock rather than a whole share. This matters because some stocks cost $200 or $300 per share, and fractional shares let you invest in them without that much cash.

Most people start with $500 to $2,000, but that is a choice, not a requirement. The real constraint is this: money you invest in stocks should be money you will not need for at least three to five years. Stock prices go up and down in the short term, and if you need the money in two years, you might have to sell at a loss. If you have high-interest debt or no emergency fund, pay those down first.

After you open the account and deposit money, that cash sits in your account as a balance. You then use it to buy stocks whenever you choose. You do not have to spend it all at once.

Individual stocks versus funds: what to buy

Once you have an account and money in it, you face a choice: buy individual stocks or buy funds.

Individual stocks mean you pick specific companies — Apple, Microsoft, Tesla — and buy shares of them. You own a piece of that one company. If you choose this route, you need to research the company: read its financial statements, understand its business, and decide whether you think the stock price will go up. This takes time and carries risk. If you pick poorly, that stock can lose 50 percent of its value or more.

Index funds and ETFs are baskets of stocks bundled together. An index fund tracking the S&P 500, for example, owns pieces of 500 large U.S. companies at once. You buy one fund and when ready own 500 companies. This spreads your risk — if one company fails, it barely affects your fund. Index funds require almost no research because you are betting on the overall market, not on individual companies. Most index funds charge very low fees, usually between 0.03 and 0.20 percent per year.

For beginners, index funds or ETFs are usually the better choice. They are simpler, less risky, and historically have outperformed most people who pick individual stocks.

How to place your first trade

Once your account is funded, you are ready to buy. Log into your brokerage account and look for a "Buy" or "Trade" button. You will enter the stock symbol — a short code like AAPL for Apple or SPY for an S&P 500 index fund. The brokerage will show you the current price and let you choose how many shares to buy.

You can buy whole shares or fractional shares. If a stock costs $150 and you have $500, you could buy 3 whole shares for $450, or you could buy 3.33 shares to spend closer to $500. Most brokerages let you do either.

After you confirm the order, the trade executes almost when ready during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays). Your account balance drops by the amount you spent, and your holdings now show the shares you own. You can sell anytime during market hours by clicking "Sell" and following the same steps.

Understanding risk and what can go wrong

Stock prices move every day based on company performance, economic news, and investor sentiment. A stock you buy for $50 might be worth $45 next week or $60. If you sell at $45, you lose $5 per share. If you hold until it reaches $60, you gain $10 per share. The longer you hold, the more time the market has to recover from downturns.

The biggest mistake beginners make is investing money they will need soon, then panicking when the price drops and selling at a loss. If you invest $1,000 and it drops to $900 in six months, you have lost $100 on paper. If you do not need that money for five years, you can wait for it to recover. If you need it in six months, you should not have invested it.

Another common mistake is buying stocks based on tips from friends or social media. Successful investing requires research or a willingness to accept the market average by buying index funds. Hot tips usually come too late and carry hidden risks.

Tax considerations and account types

When you sell a stock for more than you paid, you owe capital gains tax on the profit. The tax rate depends on how long you held the stock and your income level. Long-term capital gains (stocks held over one year) are taxed at lower rates than short-term gains.

You can reduce taxes by using a tax-advantaged account like a traditional IRA or Roth IRA instead of a regular brokerage account. These accounts let your investments grow without paying taxes on gains each year. Contribution limits explore — for 2024, you can contribute up to $7,000 per year to an IRA if you are under 50. Your brokerage can help you open an IRA and move money into it.

A regular brokerage account has no contribution limits and no restrictions on when you withdraw money. An IRA has contribution limits but offers tax benefits. Most beginners start with a regular account and move to an IRA once they understand the difference.

Frequently Asked Questions

Can I lose more money than I invest?

No. If you buy a stock for $100 and it drops to $0, you lose $100. You cannot lose more than you put in. However, if you borrow money to invest (called margin), you can lose more than your initial investment. Beginners should not use margin.

How often should I check my account?

Daily checking is normal but not necessary. Stock prices move constantly, but frequent checking often leads to panic selling. Most investors check their account monthly or quarterly. If you are investing for retirement, checking once or twice a year is fine.

What is the difference between a stock and a bond?

A stock is ownership in a company. A bond is a loan you make to a company or government, and they pay you interest. Stocks have higher potential returns but higher risk. Bonds are more stable but return less. Many investors own both.

Do I need to pick stocks or can I just buy index funds?

You can do either. Index funds are simpler and historically perform better for most people. Picking individual stocks is more interesting to some people but requires more research and carries more risk. Both are valid approaches.

When should I sell a stock I own?

Sell when you need the money, when the stock no longer fits your plan, or when you have reached your profit target. Avoid selling just because the price dropped — that locks in your loss. If you bought an index fund for retirement, you might hold it for decades.
