You need a brokerage account, money to invest, and a basic understanding of what you are buying

Investing in stocks means buying partial ownership in companies. To do this, you open an account with a brokerage firm — a company licensed to buy and sell stocks on your behalf. You deposit money into that account, then use it to purchase shares. The brokerage holds your shares and handles the transactions. You do not need a large sum to start; many brokerages accept accounts with as little as $1, though some have minimum deposits of $500 to $2,500.

The actual mechanics are straightforward: you log into your brokerage account online or through an app, search for a stock by its ticker symbol (like AAPL for Apple), 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 shares appear in your account within one to three business days, depending on the brokerage's settlement process.

Before you open an account, you should understand that stock prices move constantly and you can lose money. The value of your shares can fall below what you paid for them. This is not a flaw in the system; it is how stock ownership works. Many people new to investing lose money in their first year because they buy without understanding what they own or why its price changed.

Key Takeaways

  • You open a brokerage account with a licensed firm, deposit money, and use that account to buy and sell stocks.
  • Different brokerages charge different fees and offer different tools, so comparing them before opening an account saves money over time.
  • Stocks represent ownership in companies, and their prices change based on company performance and market conditions — you can lose money.
  • You can start with a small amount of money, but you should have a plan for why you are buying each stock and how long you intend to hold it.

Choosing a brokerage: what to compare

A brokerage is where your money and shares live. Common brokerages include Fidelity, Charles Schwab, E*TRADE, Interactive Brokers, and Robinhood. Each one operates differently, so the choice matters. Start by comparing three things: trading fees, account minimums, and the tools they offer.

Trading fees are what the brokerage charges you each time you buy or sell a stock. Many major brokerages now charge zero commission per trade, meaning you pay nothing to execute the transaction itself. However, some brokerages charge per trade, and some charge monthly account fees if your balance falls below a threshold. A brokerage that charges $5 per trade costs you $50 if you make ten trades in a month. Over a year, that adds up. Read the fee schedule on the brokerage's website before you open an account.

Account minimums vary widely. Some brokerages let you open an account and start trading with $1. Others require $500, $1,000, or $2,500 before you can place your first trade. If you have $300 to invest, a brokerage with a $1,000 minimum will not work for you. Check the minimum before explore.

Tools and research matter if you plan to research stocks yourself. Some brokerages offer detailed company financial reports, stock screeners (tools that filter stocks by criteria you set), and educational content. Others offer minimal research tools. If you are a beginner, you may not need advanced tools yet, but knowing what is available helps you choose a platform you will not outgrow quickly.

Opening an account and funding it

Opening a brokerage account takes 10 to 20 minutes online. You will need your Social Security number, a government-issued ID, your address, employment information, and banking details. The brokerage verifies your identity and runs a background check. This is standard practice and required by law.

After your account is approved — usually within one business day — you fund it by linking a bank account. You can transfer money from your checking or savings account to your brokerage account. This transfer typically takes three to five business days. Some brokerages offer faster transfers if you pay a small fee, but most people wait the standard time.

Once the money arrives in your brokerage account, it sits there as cash until you buy stocks. You can leave it there as long as you want. There is no pressure to invest when ready. Many beginners deposit money, wait a few weeks while they research companies, and then make their first purchase.

Understanding what you are buying

A stock is a share of ownership in a company. If a company has 1 million shares outstanding and you own 100 shares, you own 0.01% of that company. When the company makes money, you benefit as a shareholder. When it loses money, your ownership stake becomes less valuable. Stock prices reflect what other investors think the company is worth right now.

Stock prices change constantly during market hours. A company's stock might be worth $50 in the morning and $52 by afternoon. This happens because investors are constantly buying and selling based on news, earnings reports, economic data, and their own predictions about the future. You cannot control these price movements. You can only decide whether to buy, hold, or sell based on your own judgment.

Before you buy a stock, learn something about the company. Read its annual report, check recent news, and understand what it does. Many beginners buy stocks based on a tip from a friend or a headline they saw, without knowing anything about the business. This is how people lose money. You do not need to become an informed, but you should know why you own what you own.

Different ways to invest: individual stocks versus funds

You can buy individual stocks — shares in specific companies like Microsoft or Coca-Cola — or you can buy funds, which are baskets of many stocks bundled together. The two main types of funds are mutual funds and exchange-traded funds (ETFs).

An ETF is a collection of stocks that trades like a single stock. For example, the Vanguard S&P 500 ETF (ticker VOO) holds shares in 500 large U.S. companies. When you buy one share of VOO, you own a tiny piece of all 500 companies. If you buy 10 shares of VOO, you own a small stake in 5,000 company-shares total. ETFs spread your risk across many companies, so if one company performs poorly, it does not destroy your investment. Most ETFs charge a small annual fee called an expense ratio, typically between 0.03% and 0.50% per year.

A mutual fund works similarly but trades only once per day, after the market closes. ETFs trade throughout the day like stocks do. For beginners, ETFs are often simpler because you can buy them the same way you buy individual stocks, and they offer built-in diversification.

Individual stocks offer more control but require more research and carry more risk. If you buy one stock and the company fails, you can lose your entire investment in that stock. If you buy an ETF holding 500 stocks and one company fails, the impact is tiny. Most financial advisors recommend beginners start with ETFs or mutual funds rather than individual stocks.

Common mistakes to avoid

The first mistake is investing money you cannot afford to lose. Stock prices fall. If you invest your emergency fund or money you need in six months, a market downturn can force you to sell at a loss. Only invest money you can leave alone for at least three to five years.

The second mistake is buying without a plan. Many beginners see a stock price drop and panic-sell, locking in a loss. Others hold a losing stock hoping it will recover, missing the chance to invest in something better. Before you buy, decide why you are buying and how long you plan to hold. Write it down. When the price moves and emotions kick in, you can refer back to your plan.

The third mistake is trading too frequently. Every time you buy or sell, you pay fees and potentially owe taxes. Frequent trading also encourages emotional decisions. Research shows that people who trade less often end up with better returns than people who trade constantly.

The fourth mistake is putting all your money into one stock or one sector. If you buy only technology stocks and the tech sector falls, your entire portfolio falls. Spreading your money across different companies and industries — called diversification — protects you when one area underperforms.

Tax considerations when you sell

When you sell a stock for more than you paid for it, you owe capital gains tax on the profit. The tax rate depends on how long you held the stock. If you held it for less than one year, it is taxed as short-term capital gains at your ordinary income tax rate. If you held it for one year or longer, it is taxed as long-term capital gains, which has lower tax rates (0%, 15%, or 20%, depending on your income).

This is one reason to hold stocks longer rather than trading frequently. Long-term capital gains are taxed at lower rates. Your brokerage will send you a tax form (Form 1099-B) at the end of the year listing all your sales and gains or losses. You report this on your tax return.

If you sell a stock for less than you paid for it, you have a capital loss. You can use capital losses to offset capital gains, reducing your tax bill. You can also deduct up to $3,000 in net capital losses against your ordinary income in a single year, with any excess carrying forward to future years.

Frequently Asked Questions

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

Many brokerages accept accounts with $1 or no minimum at all. However, some require $500 to $2,500 before you can place your first trade. Check the specific brokerage's requirements. Even with $100, you can start investing in ETFs or fractional shares (partial ownership of a stock), which many brokerages now offer.

Can I lose all my money investing in stocks?

Yes, if you invest in a single stock and the company goes bankrupt, you can lose your entire investment in that stock. This is why diversification matters. If you spread your money across many stocks through an ETF or mutual fund, one company's failure has minimal impact on your overall portfolio.

When can I buy and sell stocks?

The stock market is open Monday through Friday, 9:30 a.m. to 4 p.m. Eastern time. You can place orders during these hours and they execute when ready. You can also place orders outside market hours (called after-hours trading), but execution is not may provide and prices may be different. Most beginners should stick to regular market hours.

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

You can do either. Many successful long-term investors buy only ETFs or mutual funds and never pick individual stocks. This approach requires less research and typically performs as well as or better than picking individual stocks. It is a valid path for beginners.

What is the difference between a brokerage and a bank?

A bank holds your money and offers savings accounts and loans. A brokerage is licensed to buy and sell securities (stocks, bonds, funds) on your behalf. Some large financial institutions offer both services, but they are separate functions. Your brokerage account is not FDIC-insured like a bank account, so the money you invest in stocks is at market risk.
