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

Starting to invest in stocks means opening an account with a brokerage firm, funding it with money you can afford to lose, and then buying shares of individual companies or funds that hold many companies. You do not need a large amount to begin — most brokerages let you start with $1 or $100 — but you do need to understand that stock prices move up and down, and money you invest may be worth less when you need it.

The first decision is whether to pick individual stocks yourself or buy funds that do the picking for you. Individual stocks require research and active decisions. Funds (usually called mutual funds or exchange-traded funds, or ETFs) spread your money across many companies at once, which reduces the risk that one bad choice will hurt you badly. Most people starting out find funds simpler and less time-consuming.

Before you open any account, make sure you have an emergency fund of three to six months of expenses in a savings account. Money in the stock market is not the place to keep cash you might need suddenly, because you may have to sell at a loss.

Key Takeaways

  • You open a brokerage account online in about 15 minutes, fund it with a bank transfer, and can buy your first stock or fund the same day.
  • Funds that track a broad market index (like the S&P 500) are a common starting point because they spread risk across hundreds of companies and require no stock-picking skill.
  • The money you invest should be money you will not need for at least five years, because short-term stock price swings can work against you.
  • You pay no commission to buy or sell stocks at most major brokerages, but you may pay a small fee if you buy certain funds or trade very frequently.

Choose a brokerage and open an account

A brokerage is a company that lets you buy and sell stocks and funds. Major brokerages include Fidelity, Charles Schwab, E-Trade, Vanguard, and Robinhood. Each one has a website and a mobile app where you can manage your account. Most do not charge a commission when you buy or sell stocks, though some charge small fees for certain funds or services.

To open an account, you visit the brokerage's website, provide your name, address, Social Security number, and employment information, and link a bank account. The process takes about 15 minutes. The brokerage will ask what type of account you want — a regular taxable account (called a brokerage account) or a tax-advantaged account like an IRA. If you are just starting, a regular brokerage account is simpler; you can open an IRA later once you understand how investing works.

After you open the account, you transfer money from your bank account to your brokerage account. This usually takes one to three business days. Once the money arrives, you can buy stocks or funds immediately.

Decide between individual stocks and funds

An individual stock is a share of ownership in one company. If you buy 10 shares of Apple, you own a small piece of Apple. Individual stocks can go up or down sharply depending on how the company performs. Picking individual stocks requires research — reading financial reports, understanding the business, and watching news about the company.

A fund is a collection of stocks bundled together. When you buy one share of a fund, you own a tiny piece of every stock in that fund. For example, an S&P 500 index fund holds shares in 500 large U.S. companies. If one company in the fund performs poorly, it barely affects your fund because the other 499 companies balance it out. Funds are less risky than individual stocks because your money is spread across many companies instead of bet on one.

Most beginners start with funds, especially index funds that track a broad market index. An index is just a list of stocks — the S&P 500 is the 500 largest U.S. companies, and the total stock market index includes thousands of companies. Index funds are cheap to own (fees are often less than 0.1% per year) and require no stock-picking skill. You buy one fund and own hundreds or thousands of companies automatically.

Start with an amount you can afford to keep invested

You do not need much money to begin. Most brokerages let you buy your first fund or stock with $1, $10, $100, or whatever you have. The real question is not how much to start with, but how much you can afford to leave invested without touching it for years.

Stock prices move up and down constantly. Over long periods (five years or more), stocks have historically trended upward, but over short periods they can drop sharply. If you invest $1,000 and the market falls 20% next month, your $1,000 becomes $800. If you need that money for an emergency, you have to sell at a loss. This is why money you might need soon should stay in a savings account, not the stock market.

A common approach is to invest money you will not need for at least five to ten years. If you have $500 a month left over after paying bills and building an emergency fund, you might invest that $500 every month. This is called dollar-cost averaging, and it means you buy more shares when prices are low and fewer when prices are high, which smooths out the ups and downs.

Make your first purchase

Once your brokerage account is funded, buying a stock or fund takes a few clicks. You search for the stock ticker (a short code like AAPL for Apple or VOO for a Vanguard S&P 500 fund) or the fund name, choose how many shares you want to buy, and confirm the order. The purchase happens immediately during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays), or at the market open the next day if you buy after hours.

If you are buying an index fund for the first time, you might invest a lump sum and then set up automatic monthly investments. For example, you could invest $2,000 today in a total stock market index fund, then have $200 automatically transferred from your bank account and invested every month. This removes the emotion from investing — you are not trying to time the market or guess whether now is a good time to buy.

Understand what happens after you buy

After you own stocks or funds, you do not have to do anything. You own them, and they sit in your account. You can check their price whenever you want through your brokerage app, but checking every day often leads to panic selling when prices drop. Most investors check their accounts once a month or once a quarter.

If your fund pays dividends (small cash payments that some companies and funds distribute to shareholders), the brokerage will automatically reinvest them into more shares of the fund unless you tell it not to. This is usually the right choice for beginners because it means your money keeps growing without you having to do anything.

Over time, as you learn more about investing and your comfort grows, you may want to add individual stocks, explore other types of investments, or adjust how much you invest. But for most people, buying a low-cost index fund and investing regularly is a complete strategy that works.

Common mistakes to avoid

The biggest mistake beginners make is investing money they will need soon. Stock prices can fall 10%, 20%, or more in a single year. If you need that money in two years, you might have to sell at a loss. Keep short-term money in a savings account.

Another common mistake is trying to pick individual stocks without doing research, or buying stocks because a friend or a social media post recommended them. Stock prices can move on rumors and hype, and most people who try to pick individual stocks underperform the market. Starting with an index fund removes this risk.

A third mistake is selling in a panic when the market drops. Markets fall regularly — sometimes 10% or 20% in a year — but they have historically recovered and gone higher. If you sell when prices are down, you lock in a loss. If you stay invested, you own the recovery.

Frequently Asked Questions

How much money do I need to start investing?

Most brokerages let you start with $1 or $100. The amount matters less than having money you will not need for several years. Start with whatever you can afford to invest regularly and leave alone.

What is the difference between a brokerage account and an IRA?

A brokerage account has no contribution limits and no tax advantages — you pay taxes on gains and dividends each year. An IRA (Individual Retirement Account) has annual contribution limits but offers tax breaks — either you pay no taxes on gains until you withdraw (traditional IRA) or you pay no taxes on gains ever (Roth IRA). Start with a brokerage account if you are new; open an IRA once you understand the basics.

Can I lose all my money in the stock market?

If you own an index fund with hundreds of companies, losing everything would require nearly every large U.S. company to fail, which has never happened. Individual stocks can go to zero, but funds spread risk across many companies. This is why funds are safer for beginners.

When should I sell stocks or funds I own?

Most investors do not sell until they need the money. If you are investing for retirement decades away, you may never sell. If you need money for a house down payment in five years, you might sell then. Avoid selling because you are nervous about price drops — that usually locks in losses.

Do I need to pick individual stocks to make money?

No. Most professional investors underperform index funds over long periods. Buying a low-cost index fund and investing regularly is a proven strategy that works for most people. Individual stocks are optional and require more research and risk.
