Using stocks means buying shares of ownership in companies, then making money when those shares increase in value or pay you cash dividends. The process starts with opening a brokerage account, funding it, placing trades, and then managing your holdings over time. Whether you want long-term growth, regular income, or both, here’s how the whole system works in practice.
Opening a Brokerage Account
Before you can buy a single share, you need a brokerage account. This is a specialized account, similar to a bank account, that holds your investments. Most major brokerages let you open one online in under 15 minutes.
You’ll be asked for your Social Security number (required for tax reporting to the IRS), a government-issued ID like a driver’s license or passport, and basic personal details: your age, employment status, income, and investment experience. Brokerages ask these questions partly for identity verification and partly to understand your financial situation and risk tolerance.
Once your account is open, you’ll choose between two main account types. A cash account means you buy stocks only with money you’ve deposited. If you want $1,000 worth of stock, you need $1,000 in the account. A margin account lets you borrow money from the brokerage to buy stocks, which amplifies both gains and losses. Beginners should stick with a cash account. Margin trading adds complexity and real risk of losing more than you put in.
Most brokerages accept bank transfers, wire transfers, and sometimes checks to fund your account. Many also include a cash sweep feature that automatically moves uninvested cash into a money market fund or bank deposit so it earns a small return while you decide what to buy.
Placing Your First Trade
Once your account is funded, buying stock is straightforward. You search for the company by name or ticker symbol (the short abbreviation used on exchanges, like AAPL for Apple), choose how many shares you want, select an order type, and submit. The order typically settles one business day after you place it.
The order type you choose determines how your trade gets executed:
- Market order: Buys or sells immediately at whatever the current price is. You’re guaranteed the trade will go through, but the exact price might shift slightly between the moment you click and the moment the order fills. This is the simplest option for beginners.
- Limit order: Lets you set the maximum price you’re willing to pay (when buying) or the minimum you’ll accept (when selling). If you want shares of a company but only at $50 or less, a buy limit order at $50 will only execute if the price drops to that level. The trade might never happen if the price stays above your limit.
- Stop order: Triggers a sale (or purchase) once a stock hits a specific price. Investors commonly use sell stop orders as a safety net. If you own a stock trading at $80 and set a stop order at $70, your shares automatically sell if the price falls to $70, limiting your loss.
For most routine purchases, a market order during normal trading hours works fine. Limit orders become more useful when you’re buying volatile stocks or want to lock in a specific entry price.
Two Ways Stocks Make You Money
Stocks generate returns in two distinct ways, and understanding both helps you decide what to buy.
Capital Appreciation
This is the classic “buy low, sell high.” You purchase shares hoping the company grows in value over time, and your profit comes from selling at a higher price than you paid. Growth-oriented stocks tend to be companies reinvesting their profits into expansion rather than paying cash to shareholders. These stocks can deliver strong long-term returns, but they also tend to be more volatile, with bigger price swings along the way.
Dividends
Some companies distribute a portion of their profits to shareholders as regular cash payments called dividends. These typically arrive quarterly. You can pocket the cash as income, or you can reinvest it to buy more shares. Reinvesting dividends creates a compounding effect: your new shares generate their own dividends, which buy even more shares, building a snowball over time. Most brokerages let you turn on automatic dividend reinvestment with a single setting.
Many investors use both approaches. Younger investors with decades ahead often lean toward growth stocks, while those closer to retirement or wanting steady income may favor dividend-paying stocks. There’s no rule saying you can’t hold both in the same account.
Building a Diversified Portfolio
Putting all your money into one or two individual stocks is risky. If that company hits trouble, your entire investment suffers. Diversification means spreading your money across many companies so no single failure can wreck your portfolio.
The easiest way to diversify is through ETFs (exchange-traded funds) or mutual funds. An ETF trades on the stock exchange just like a regular stock, but inside it holds hundreds or even thousands of individual stocks. When you buy one share of a broad market ETF, you’re effectively owning a small slice of every major company in that index. Your returns reflect the average performance of the entire group rather than the fate of any single business.
Index funds, a popular type of ETF or mutual fund, track a specific market index like the S&P 500. They’re low-cost, require almost no decision-making, and historically deliver solid long-term returns. For someone just starting out, a broad index fund is often the simplest path to owning stocks without needing to research individual companies.
As you gain confidence, you might add individual stocks alongside your index funds. A common approach is keeping the bulk of your portfolio in diversified funds and allocating a smaller portion to individual companies you’ve researched and believe in.
How Taxes Work on Stock Profits
When you sell a stock for more than you paid, the profit is a capital gain, and you owe taxes on it. How much you owe depends on how long you held the stock.
Short-term capital gains apply to stocks held for one year or less. These profits are taxed at your ordinary income tax rate, the same rate you pay on your salary. For someone in a higher tax bracket, this can take a significant bite.
Long-term capital gains apply to stocks held for more than one year. The tax rates are lower: 0%, 15%, or 20%, depending on your taxable income and filing status. Most people fall into the 0% or 15% bracket for long-term gains. Higher earners may also owe an additional 3.8% net investment income tax on top of the standard rate.
This tax structure creates a strong incentive to hold stocks for at least a year before selling. You don’t owe any tax on gains until you actually sell, so buying and holding for the long term is both a common investment strategy and a tax-efficient one. Dividends are also taxable in the year you receive them, though qualified dividends (from most U.S. companies) are taxed at the lower long-term capital gains rates.
If you hold stocks inside a tax-advantaged account like a Roth IRA or traditional IRA, different rules apply. In a Roth IRA, qualified withdrawals are completely tax-free. In a traditional IRA, you defer taxes until you withdraw the money in retirement. Using these accounts for stock investments can significantly reduce the taxes you pay over a lifetime of investing.
Practical Tips for Getting Started
Start with money you won’t need for at least five years. Stock prices fluctuate daily, and short-term drops are normal. If you might need the cash in six months, a savings account is a better fit. The stock market has historically trended upward over long periods, but any given year can be negative.
Many brokerages now offer fractional shares, meaning you can buy a partial share of an expensive stock for as little as $1 or $5. This removes the barrier of needing hundreds of dollars to buy a single share of a high-priced company. It also makes it easier to spread a small amount of money across several investments right away.
Set up automatic recurring investments if your brokerage offers them. Investing a fixed amount on a regular schedule, sometimes called dollar-cost averaging, means you buy more shares when prices are low and fewer when prices are high. Over time, this smooths out the impact of market swings and removes the pressure of trying to time your purchases perfectly.
Keep an eye on fees. Most major brokerages charge $0 commissions on stock and ETF trades, but some mutual funds carry expense ratios (an annual fee expressed as a percentage of your investment). A fund with a 0.03% expense ratio costs you 30 cents per year for every $1,000 invested. A fund charging 1% costs $10 per year on the same amount. Those differences compound significantly over decades.
