A common stock account holds shares of ownership in companies

A common stock account is a brokerage account where you buy and own pieces of companies. When you buy a share of stock, you own a small part of that company. If the company does well and its stock price goes up, your shares become worth more. If it does poorly, they become worth less. You can sell your shares whenever you want during market hours, and you keep any profit you make.

The account itself is just the container — the brokerage (the company that holds your money and executes your trades) manages it for you. You deposit cash into the account, use that cash to buy shares, and the brokerage keeps track of what you own and its current value. You can hold shares for one day or thirty years. There is no required holding period.

Common stock is different from other types of investments you might hold in a brokerage account, like bonds or mutual funds. With common stock, you own actual pieces of real companies and have a claim on their future earnings. You may also receive dividends — small cash payments that some companies send to shareholders — though not all companies pay them.

Key Takeaways

  • A common stock account lets you buy and sell shares of individual companies through a brokerage.
  • You own a real piece of each company whose stock you buy, and your shares gain or lose value as the company's fortunes change.
  • You can sell your shares at any time during market hours, and you keep any profit after paying any taxes owed.
  • Some companies pay dividends to shareholders, but many do not, and dividends are separate from any gain or loss in the stock price itself.
  • Common stock accounts have no required holding period and no contribution limits, unlike retirement accounts.

How buying and selling shares actually works

When you want to buy a stock, you log into your brokerage account and place an order. You tell the brokerage which company's stock you want (identified by a ticker symbol — a short code like AAPL for Apple or MSFT for Microsoft), how many shares you want, and what price you are willing to pay. Most people use a market order, which means "buy at whatever the current price is right now." The order executes almost when ready during market hours (usually 9:30 a.m. to 4 p.m. Eastern time on weekdays).

The cash comes out of your account when ready, and the shares appear in your account within one business day. You now own those shares. If you want to sell them later, you place a sell order the same way. The cash from the sale lands back in your account within one business day, and you can then withdraw it or use it to buy other stocks.

The price you pay per share changes constantly — sometimes by pennies, sometimes by dollars — based on what other buyers and sellers are willing to pay at that moment. You have no control over the price itself. You only control whether to buy, sell, or hold.

What happens to your money and how you pay taxes

Your cash sits in the brokerage account until you use it to buy stock or withdraw it. The brokerage does not pay you interest on cash sitting idle — it just holds it. Some brokerages offer a small interest rate on uninvested cash, but this is rare and usually very low.

When you sell a stock for more than you paid for it, you owe taxes on the profit. The amount of tax depends on how long you held the stock. If you held it for less than one year, the profit is taxed as short-term capital gains, which is taxed at your regular income tax rate. If you held it for one year or longer, it is taxed as long-term capital gains, which usually has a lower tax rate. The brokerage will send you a tax form (Form 1099-B) at the end of the year showing all your sales and gains.

If you sell a stock for less than you paid for it, you have a loss. You can use that loss to offset other gains, which can reduce your taxes. If you have more losses than gains in a year, you can deduct up to $3,000 of losses against your regular income, and carry forward any remaining losses to future years.

Common stock accounts versus retirement accounts

A common stock account is a taxable brokerage account, which means you pay taxes on gains and dividends each year. This is different from a retirement account like an IRA or 401(k), where you do not pay taxes on gains until you withdraw the money (or ever, in the case of a Roth IRA).

Taxable brokerage accounts have no contribution limits — you can deposit and invest as much as you want. Retirement accounts have annual limits (for example, you can contribute $7,000 to an IRA in 2024, though this changes year to year). However, retirement accounts have withdrawal restrictions — you usually cannot touch the money until age 59½ without paying a penalty. A common stock account has no such restrictions. You can withdraw your money whenever you want.

Many people use both. They max out their retirement accounts first (because of the tax advantages), then use a taxable brokerage account for additional investing or for money they might need before retirement.

Dividends and what they mean for your account

Some companies pay dividends — regular cash payments to people who own their stock. A company might pay a dividend of $0.50 per share four times a year, for example. If you own 100 shares, you would receive $50 each quarter. The dividend is separate from any gain or loss in the stock price itself.

Not all companies pay dividends. Young, fast-growing companies often reinvest all their profits back into the business instead of paying shareholders. Mature, stable companies are more likely to pay dividends. You can see whether a company pays a dividend by looking it up on your brokerage's website or on financial websites like Yahoo Finance.

When a company pays a dividend, the cash lands in your brokerage account automatically. You can then withdraw it, spend it, or reinvest it by buying more shares. Some brokerages offer dividend reinvestment (often called DRIP), which automatically buys more shares with your dividend instead of leaving it as cash.

You owe taxes on dividends in the year you receive them, just like you owe taxes on gains when you sell. The tax rate depends on whether the dividend is may have access to (usually lower tax rate) or non-may have access to (taxed as regular income). Your brokerage will tell you which type each dividend is on your year-end tax form.

Risks and what can go wrong

Stock prices fall as well as rise. If you buy a stock at $50 per share and it drops to $30, you have lost $20 per share. You can hold and hope it recovers, or you can sell and lock in the loss. There is no may provide it will recover. Companies go out of business, and shareholders can lose their entire investment.

The stock market is also volatile — prices swing up and down, sometimes sharply, based on news, earnings reports, economic conditions, and investor sentiment. If you need your money in the next few months, the stock market may not be the right place for it. Money you will need soon should stay in a savings account or money market account where it is stable.

Brokerages themselves are regulated and insured, so your cash and shares are protected even if the brokerage fails. However, the brokerage does not protect you from losses in the stocks themselves — that is the risk you take when you invest.

Getting started with a common stock account

To open a common stock account, you choose a brokerage and complete their account opening process online. Most brokerages ask for your name, address, Social Security number, employment information, and banking details. The process usually takes 10 to 15 minutes. You will need to verify your identity, which the brokerage does electronically.

Once your account is open, you link a bank account and deposit cash. The cash usually arrives within one to three business days. Then you can start buying stocks. Most brokerages charge no commission to buy or sell stocks, though some charge small fees for certain types of trades or accounts.

Before you start, decide how much you can afford to invest and how long you can leave it invested. Stock investing works best over years or decades, not weeks or months. If you are new to stocks, consider starting small and learning as you go, or reading about investing strategies before you commit large amounts of money.

Frequently Asked Questions

Can I lose more than the money I invested?

No. With common stock, the worst that can happen is the stock goes to zero and you lose your entire investment. You cannot owe money to the brokerage or lose more than you put in. (This is different from buying stocks on margin, where you borrow money to invest — that is a separate, riskier strategy.)

Do I have to hold a stock for a minimum amount of time?

No. You can buy a stock and sell it the same day if you want. However, selling within one year means any profit is taxed at your regular income tax rate instead of the lower long-term capital gains rate. There is no penalty from the brokerage for selling quickly — the tax consequence is the only downside.

What if a company I own stock in goes bankrupt?

Your shares become worthless, and you lose your investment. Bankruptcy courts prioritize creditors and bondholders before common stockholders, so shareholders often get nothing. This is why diversifying — owning many different stocks instead of a few — is important.

Can I set up automatic investments in a common stock account?

Yes. Most brokerages let you set up automatic transfers from your bank account and automatic purchases of specific stocks or funds on a schedule you choose (weekly, monthly, etc.). This is called dollar-cost averaging and can help reduce the impact of price swings over time.

Is a common stock account the same as a brokerage account?

A brokerage account is the container; a common stock account is one type of thing you can hold inside it. You can hold stocks, bonds, mutual funds, exchange-traded funds, and other investments all in the same brokerage account. Common stock is just one option.
