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 companies or funds. You do not need a large sum to begin — most brokerages let you start with $100 or less. The real work is deciding whether you are ready financially, understanding what you are buying, and sticking to a strategy rather than reacting to price swings.

The process itself takes a few days from start to first purchase. The harder part is the thinking that comes before: making sure you have an emergency fund separate from your investment money, understanding that stock prices fall as well as rise, and knowing whether you want to pick individual companies or buy funds that hold many companies at once.

Key Takeaways

  • You open a brokerage account online in minutes, fund it from your bank account, and can buy stocks the same day or within a few days depending on how you transfer money.
  • Most new investors should keep their investment money separate from emergency savings and only invest money they will not need for at least three to five years.
  • Index funds and exchange-traded funds (ETFs) let you own pieces of many companies with a single purchase, which reduces risk compared to buying individual stocks.
  • Brokerage fees have largely disappeared, but you still pay the difference between the bid and ask price when you buy or sell, and you may owe taxes on gains when you sell at a profit.
  • A written plan — even a simple one — helps you avoid panic selling when prices drop or chasing hot stocks when prices rise.

Decide if you are financially ready to invest

Before you open any account, make sure you have money set aside that you will not need for emergencies. Most financial advisors suggest keeping three to six months of living expenses in a savings account separate from your investment money. If you raid your investment account to pay a car repair or medical bill, you may have to sell stocks at a loss.

You also need to be honest about your timeline. Money you invest in stocks should stay there for at least three to five years, ideally longer. Stock prices swing up and down in the short term, and if you need the money in two years, you might be forced to sell when prices are down. If you know you will need money within the next few years, a high-yield savings account or money market fund is safer than stocks.

Finally, consider your debt. If you carry credit card balances at 18% or 20% interest, paying those down usually makes more financial sense than investing in stocks, because the may provide return from eliminating that interest is higher than the average stock market return.

Choose a brokerage and open an account

A brokerage is a company that lets you buy and sell stocks. The major ones include Fidelity, Charles Schwab, E-Trade, Vanguard, and Robinhood. They all offer accounts online, and the process takes 10 to 20 minutes. You will need your Social Security number, a government ID, your address, and your bank account information.

Most brokerages no longer charge commissions to buy or sell stocks or funds, so the cost difference between them is small. What matters more is the user interface — whether the website or app makes sense to you — and whether they offer the funds or stocks you want to buy. For a new investor, any of the major brokerages will work fine.

After you open the account, you link it to your bank account and transfer money in. A transfer from your bank usually takes one to three business days to show up in your brokerage account. Some brokerages offer instant transfers for a small fee, or you can write a check. Once the money is there, you can buy stocks or funds immediately.

Understand the difference between individual stocks and funds

An individual stock is a share of one company. When you buy Apple stock, you own a tiny piece of Apple. If you want to own pieces of 50 companies, you have to buy 50 different stocks. This requires research, time, and carries more risk because if one company fails, that part of your money is gone.

A fund is a collection of many stocks (or bonds, or both) bundled together. An index fund tracks a list of companies — for example, the S&P 500 index fund holds shares in 500 large U.S. companies. An exchange-traded fund (ETF) is similar but trades like a stock during the day. When you buy one fund, you own a piece of all the companies in it. If one company fails, it barely affects your fund because you own pieces of hundreds of others.

For most new investors, starting with a low-cost index fund or ETF is simpler and less risky than picking individual stocks. You can always buy individual stocks later once you understand how they work. A common starting point is an S&P 500 index fund, which gives you broad exposure to large U.S. companies with one purchase.

Make your first purchase

Once your money is in your brokerage account, buying is straightforward. Log into your account, search for the stock or fund you want to buy by its ticker symbol (a short code like AAPL for Apple or VOO for a Vanguard S&P 500 ETF), and enter how many shares you want. The system shows you the current price and the total cost. You confirm, and the order goes through.

Most orders execute immediately during market hours (9:30 a.m. to 4 p.m. Eastern time, Monday through Friday). If you place an order after hours or on a weekend, it will execute when the market opens. You can set a limit order, which means "only buy if the price drops to this level," or a market order, which means "buy at whatever the current price is." For a new investor, market orders are simpler.

After your purchase, you own the shares. Your brokerage account shows your holdings, their current value, and how much you have gained or lost. You do not need to do anything else unless you want to buy more or sell.

Know what costs you will pay

Most brokerages charge zero commission to buy or sell stocks and funds, which is a major change from 20 years ago. However, you still pay costs in other ways. When you buy a stock, there is a difference between what sellers are asking and what buyers are offering — called the bid-ask spread. This difference is usually small (a few cents per share) but adds up if you trade often.

Funds themselves may have an expense ratio, which is an annual fee charged as a percentage of your money. A low-cost index fund might charge 0.03% per year, meaning you pay $3 per year for every $10,000 invested. Some actively managed funds charge 1% or more. Over decades, this difference compounds significantly.

When you sell a stock or fund at a profit, you owe taxes on the gain. The tax rate depends on how long you held it — if you held it more than a year, the rate is usually lower. This is another reason to think of stock investing as a long-term activity, not a way to make quick money.

Create a simple plan and stick to it

The biggest mistake new investors make is reacting emotionally to price swings. When stocks drop 10%, fear kicks in and people sell. When stocks rise 20%, greed kicks in and people buy at the peak. A written plan prevents this. Your plan does not need to be complex — it can be as simple as: "I will invest $500 per month in an S&P 500 index fund for the next 20 years and not check the price more than once a quarter."

A strategy called dollar-cost averaging — investing the same amount at regular intervals — removes the pressure to time the market perfectly. You buy more shares when prices are low and fewer when prices are high, which smooths out the ups and downs.

Write down your plan, including how much you will invest, what you will buy, and how often you will check on it. Then follow it. Ignore news headlines about stocks, ignore what friends are buying, and ignore the urge to sell when prices drop. History shows that investors who stay the course for years do far better than those who trade constantly.

Frequently Asked Questions

How much money do I need to start investing in stocks?

Most brokerages let you start with $100 or even $1. However, if you are buying individual stocks, you might want at least $500 to $1,000 so you can own pieces of several companies and spread your risk. If you are buying a fund, $100 is enough to get your free guide.

Can I lose all my money investing in stocks?

If you own a single company stock and that company goes bankrupt, you can lose your entire investment in that stock. However, if you own a diversified fund with hundreds of companies, the chance of losing everything is extremely low. This is why funds are safer for new investors.

Should I invest in individual stocks or funds?

Most new investors should start with funds because they require less research and carry less risk. Once you understand how the market works and have time to research companies, you can add individual stocks if you want. Many experienced investors use both.

What is the difference between a stock and an ETF?

A stock is a share of one company. An ETF is a fund that holds many stocks and trades like a stock during the day. ETFs are usually cheaper and less risky than individual stocks because you own pieces of many companies at once.

How often should I check on my investments?

Once or twice a quarter is enough. Checking daily or weekly encourages emotional decisions. If you are investing regularly (like $500 per month), you might check when you make each deposit. Otherwise, let your money sit and grow.
