The basic steps to begin stock market investing

To invest in the stock market, you need a brokerage account — an account with a company that buys and sells stocks on your behalf. You open the account, deposit money, and then place orders to buy shares of individual companies or funds that hold many companies' shares. The brokerage holds your shares and executes your trades. You do not need a large amount of money to start, and you do not need special credentials or permission from anyone.

The actual sequence is straightforward: choose a brokerage firm, complete their account setup (which includes providing identification and tax information), link a bank account or transfer money in, and then place your first trade through their website or app. Most brokerages charge no account opening fee and no minimum deposit, though some have a minimum to start investing in certain products like mutual funds.

The hardest part is usually deciding what to buy, not the mechanics of buying it. Many people start by buying index funds or exchange-traded funds (ETFs) — these are baskets of many stocks bundled together, so you own a piece of hundreds of companies at once rather than betting on a single stock.

Key Takeaways

  • You need a brokerage account to buy stocks, which you open online with a company like Fidelity, Vanguard, Charles Schwab, or a discount broker, and most charge no fee to open one.
  • You must provide identification and tax information (your Social Security number) when you open an account, and link a bank account to deposit money.
  • Index funds and ETFs let you own pieces of many companies at once, which reduces risk compared to buying individual stocks.
  • Stocks you buy are held in your account and can be sold at any time during market hours, though selling at a loss or gain has tax consequences.
  • The stock market is open Monday through Friday during regular hours, and prices change constantly based on supply and demand.

Choosing a brokerage and opening an account

A brokerage is a company licensed to buy and sell securities on your behalf. The major ones include Fidelity, Vanguard, Charles Schwab, E*TRADE, and TD Ameritrade, but there are also smaller discount brokers and apps like Robinhood, Webull, and M1 Finance. Each charges different fees (or no fees) and offers different tools and research resources. Most have no account minimum and no opening fee.

When you open an account, you will choose between a regular taxable brokerage account or a retirement account like an IRA or 401(k). A taxable account has no contribution limits and no restrictions on when you withdraw money, but you pay taxes on gains and dividends each year. A retirement account has annual contribution limits (for 2024, $7,000 for a traditional or Roth IRA, $23,500 for a 401(k)) but lets your money grow without annual tax bills, and you typically cannot withdraw without penalty before age 59½.

The account setup takes 10 to 20 minutes. You provide your name, address, Social Security number, employment information, and bank details. The brokerage verifies your identity and then your account is ready. You can then transfer money from your bank or deposit a check.

Understanding stocks, funds, and what you are actually buying

A stock is a share of ownership in a company. When you buy one share of Apple, you own a tiny piece of Apple. The price of a stock changes based on what buyers and sellers think the company is worth. If the company does well, the stock price often rises. If it does poorly, the price often falls. You make money when you sell for more than you paid, or when the company pays you a dividend (a share of profits).

An index fund or exchange-traded fund (ETF) is a collection of stocks bundled together and sold as a single investment. For example, an S&P 500 index fund holds shares in 500 large U.S. companies. When you buy one share of the fund, you own a tiny piece of all 500 companies. This spreads your risk — if one company fails, you barely notice because you own 499 others. Most beginning investors start here rather than picking individual stocks.

A mutual fund is similar to an ETF but is usually managed by a professional who picks which stocks to buy. Mutual funds often charge higher fees (called expense ratios) than index funds because you are paying for that management. Many people find index funds a better deal because they track the market's overall performance without the extra cost.

How to place your first trade

Once money is in your account, you log into your brokerage's website or app and search for the stock or fund you want to buy. You enter the ticker symbol (a short code like AAPL for Apple or VOO for the Vanguard S&P 500 ETF), the number of shares you want, and whether you want to buy at the current market price or set a limit price (the highest you will pay). Then you review the order and submit it.

If you place a market order during market hours (9:30 a.m. to 4 p.m. Eastern time, Monday through Friday), it executes within seconds at the current price. If you place it after hours or on a weekend, it waits until the market opens and then executes. A limit order sits in the system until someone is willing to sell at your price or lower — it may never execute if the price never drops that far.

After you buy, the shares appear in your account. You can hold them as long as you want, sell them whenever you choose, or buy more. There is no time limit on how long you must hold a stock, though selling within a year of buying may have different tax treatment than holding longer.

Understanding risk and how much to invest

Stock prices go up and down. Sometimes they fall sharply and stay down for months or years. If you invest money you need within the next few years, the stock market is a risky place for it — you might be forced to sell when prices are down and lock in a loss. Money you will not need for at least five to ten years is more suitable for stocks because there is time to recover from downturns.

Diversification — owning many different stocks or funds rather than a few — reduces risk. An index fund gives you instant diversification because it holds hundreds of stocks. Owning just one or two individual stocks is riskier because a single company's bad news can hurt you significantly.

Start with an amount you can afford to lose without changing your life. Many people begin with $100 to $500 and add more over time. The key is to start, learn how the system works, and then decide whether to invest more. Do not borrow money to invest in stocks — if the market falls, you still owe the loan.

Taxes and what happens when you sell

When you sell a stock or fund for more than you paid, you have a capital gain. When you sell for less, you have a capital loss. In a taxable brokerage account, you owe federal income tax on gains. The tax rate depends on how long you held the investment: if you held it less than a year, it is taxed as ordinary income (your regular tax rate). If you held it a year or longer, it is taxed at the long-term capital gains rate, which is usually lower.

Your brokerage sends you a tax form (Form 1099-B) each January showing all your trades from the previous year. You report this on your tax return. If you have losses, you can use them to offset gains, and you can carry unused losses forward to future years.

In a retirement account like an IRA or 401(k), you do not pay taxes on gains or losses while the money is in the account. You only pay taxes when you withdraw, and only on the amount you withdraw. This is why retirement accounts are often the best place to start investing if you are saving for retirement.

Common mistakes and how to avoid them

Trying to time the market — buying when you think prices are about to rise and selling when you think they are about to fall — is extremely difficult and usually costs money. Most people do better by investing a fixed amount regularly (like $200 per month) regardless of whether prices are up or down. This is called dollar-cost averaging and removes the guesswork.

Panic selling during a market downturn locks in losses. If you invested for the long term and the market falls 20 percent, the historical pattern is that it recovers. Selling when you are scared means you miss the recovery. If you cannot tolerate seeing your account value drop without selling, you may have invested too much or in the wrong type of investment.

Chasing hot stocks or tips from friends or social media often leads to buying high and selling low. Index funds and ETFs are boring, but boring has historically beaten exciting for most investors.

Frequently Asked Questions

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

Most brokerages have no minimum deposit, so you can start with $1. However, some mutual funds have minimums of $1,000 or more. ETFs and individual stocks can be bought in any quantity, so you can start small and add more over time.

Can I lose more money than I invested?

If you buy stocks with your own money in a regular brokerage account, the worst that can happen is the stock goes to zero and you lose what you invested. You cannot lose more than you put in. However, if you borrow money to invest (called buying on margin), you can lose more than your initial investment.

What is the difference between a stock and a mutual fund?

A stock is ownership in one company. A mutual fund or ETF is a basket of many stocks. Funds reduce risk because you own pieces of many companies instead of betting on one. Funds are usually better for beginners.

Do I need to monitor my investments every day?

No. If you are investing for the long term (five years or more) in index funds, checking your account once a month or even once a year is fine. Checking every day often leads to panic selling during normal price drops. Set it and forget it is a valid strategy.

What happens if the brokerage goes out of business?

Your stocks and funds are protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 per account if a brokerage fails. Your investments are held in your name, not the brokerage's name, so they are yours even if the company closes.
