You need a brokerage account, money to invest, and a decision about what stocks or funds to buy

Investing in stocks means buying shares of ownership in companies. You do this through a brokerage account — a financial account that holds your money and executes trades. You open the account with a brokerage firm (a company like Fidelity, Charles Schwab, or Vanguard), deposit cash, and then use that account to buy and sell stocks. The brokerage holds your shares and sends you statements showing what you own and what it is worth.

The actual mechanics are straightforward: you log into your account, search for a stock by its ticker symbol (a short code like AAPL for Apple or MSFT for Microsoft), decide how many shares you want, and place an order. The order executes during market hours — typically 9:30 a.m. to 4 p.m. Eastern time on weekdays when the stock market is open. Your cash is deducted, and the shares appear in your account within one business day.

Before you open an account, you should understand what you are buying. Individual stocks are bets on single companies. Index funds and exchange-traded funds (ETFs) are bundles of many stocks, which spreads your risk. Most people starting out buy funds rather than individual stocks, because one company's failure does not wipe out your entire investment.

Key Takeaways

  • You open a brokerage account with a firm like Fidelity or Charles Schwab, deposit money, and use that account to buy stocks or funds.
  • Stock trades execute during market hours (9:30 a.m. to 4 p.m. Eastern, weekdays) and settle within one business day.
  • Index funds and ETFs hold many stocks at once, which reduces the risk that one company's poor performance will hurt your overall investment.
  • You pay fees to the brokerage for trades, and you may pay ongoing fees to funds for managing your money.
  • Stocks can lose value as well as gain it, and money you invest may not be available immediately if you need it.

Opening a brokerage account and depositing money

Choose a brokerage firm and go to their website to open an account. Most brokerages now charge zero commission on stock and ETF trades, so the main differences between them are the user interface, research tools, and customer service. Common choices include Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Vanguard. You will need to provide your name, address, Social Security number, and employment information. The process takes 10 to 15 minutes.

Once your account is open, you link a bank account and transfer money into it. This transfer usually takes one to three business days. Some brokerages offer a debit card or check-writing privileges on your brokerage account, so you can move money quickly if you need it. Do not deposit more than you can afford to lose, because stock prices fall as well as rise.

Understanding what you are buying: stocks versus funds

An individual stock is a share of one company. If you buy 10 shares of Apple, you own a tiny piece of Apple. If Apple does well, the stock price rises and you make money. If Apple struggles, the price falls and you lose money. Individual stocks are volatile — they can swing wildly in price — and they require research to pick well.

An index fund or ETF holds dozens or hundreds of stocks bundled together. An S&P 500 index fund, for example, holds shares in 500 large U.S. companies. If one company fails, it is a small part of your total investment. Funds move more slowly than individual stocks and are less risky for that reason. They also require less research — you are betting on the overall market rather than on your ability to pick winners.

Most new investors should start with funds, not individual stocks. Funds are simpler, less risky, and historically have outperformed most people who try to pick individual stocks. You can always move to individual stocks later once you understand how markets work.

Placing your first trade

Log into your brokerage account and look for a "Buy" or "Trade" button. Search for the stock or fund you want by its ticker symbol. For example, if you want to buy an S&P 500 index fund from Vanguard, you would search for VOO (the ticker). The screen will show you the current price and let you enter the number of shares you want to buy.

You can place a market order, which buys immediately at the current price, or a limit order, which buys only if the price drops to a level you set. Market orders execute right away during market hours. Limit orders may never execute if the price never reaches your target. Most beginners use market orders because they are simpler.

Once you place the order, it executes within seconds if the market is open. Your cash is deducted from your account, and the shares appear in your holdings within one business day. You will receive a confirmation email with the trade details.

Fees and costs you will encounter

Most brokerages charge zero commission on stock and ETF trades, meaning you do not pay a fee to buy or sell. However, you may pay other costs. Mutual funds and ETFs charge an annual expense ratio — a percentage of your investment that goes to the fund company for managing the fund. A fund with a 0.03% expense ratio costs $3 per year for every $10,000 you invest. Index funds typically have very low expense ratios (under 0.1%), while actively managed funds often charge more (0.5% to 1% or higher).

Some brokerages charge account maintenance fees if your balance is below a certain level, though many have eliminated these. A few charge fees for certain services like wire transfers or paper statements. Read the fee schedule on your brokerage's website before you open an account.

What happens after you buy: holding and monitoring

Once you own shares, you hold them in your account. You can check their value anytime by logging in — the price updates during market hours. You do not have to do anything. You can hold for years, or you can sell whenever you want during market hours. When you sell, the cash goes back into your brokerage account and is available to withdraw or reinvest.

Some stocks and funds pay dividends — small cash payments to shareholders, usually quarterly. Dividends are automatically deposited into your account. You can reinvest them by buying more shares, or you can leave the cash sitting in your account.

You will receive statements from your brokerage showing your holdings, their current value, and any transactions. The IRS requires you to report stock sales on your tax return, so keep these statements for your records.

Risk and what can go wrong

Stock prices fall as well as rise. If you buy a stock or fund and the price drops, you have a paper loss — you have not lost money until you sell, but the value of your investment has declined. If you need the money soon, a price drop means you might have to sell at a loss. This is why you should not invest money you need within the next few years.

Individual stocks can go to zero if the company fails. Index funds and ETFs are much safer because they hold many companies, but they can still lose 20%, 30%, or more during a market downturn. The stock market has historically recovered from every downturn, but recovery can take years.

Avoid the temptation to buy and sell frequently based on short-term price movements. Most people who trade often lose money to fees and bad timing. The most successful investors buy and hold for years, ignoring short-term noise.

Frequently Asked Questions

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

Most brokerages have no minimum deposit. You can open an account and buy a single share of a stock or fund. However, if you are buying individual stocks, you may want at least $500 to $1,000 so you can spread your money across several companies and reduce risk. If you are buying index funds, even $100 is enough to start.

Can I lose more money than I invested?

No. If you buy stocks outright with cash in your account, the worst that can happen is the stock goes to zero and you lose your entire investment. You cannot lose more than you put in. However, if you borrow money to buy stocks (called buying on margin), you can lose more than your initial investment. Beginners should avoid margin.

When should I sell a stock I own?

This depends on your goals and time horizon. If you are holding for long-term growth, you may never sell — you just hold and let the investment grow. If the price rises and you need the money, you can sell anytime during market hours. Avoid selling during a price drop out of panic; most investors who panic-sell regret it later when prices recover.

Do I have to pay taxes on stocks I own?

You do not pay taxes on stocks just for owning them. You pay taxes when you sell at a profit (called a capital gain). Long-term gains (stocks held over one year) are taxed at a lower rate than short-term gains. Dividends are also taxable. Keep records of all your trades for tax time.

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 are riskier but have higher potential returns. Bonds are safer but pay less. Many investors hold both to balance risk and return.
