What are stocks?

Key takeaways

  • Stocks represent a piece of ownership in a company.
  • Different types of stock have unique characteristics and benefits.
  • To buy stocks you need to have a brokerage account.

Stocks, company shares, equities. These investments go by a few different names and are a fundamental part of many investors' plans to build wealth. But that doesn't mean they're easily understood. To help get you up to speed, we're here to share (get it?) some knowledge about stocks and how different types could be useful to you as an investor.

What are stocks?

Stocks are a type of security that gives stockholders a share of ownership in a company. Depending on the stock type, they may also grant shareholders the right to vote on certain decisions affecting the company.

How do stocks work?

Companies issue stock to raise funds to operate their businesses. This cash infusion can help companies in a variety of ways, such as helping to pay off existing debt and funding growth plans they can't—or don't want to—finance with new loans.

Stockholders, or shareholders, can primarily make money in 2 ways:

  • Share appreciation. When a company does well financially or becomes more desirable, the price of its stock can increase. This allows investors to sell their shares to other investors for more than they paid.
  • Dividends. Some companies may decide to share a portion of their profits with investors through cash payments called dividends. A dividend yield is expressed as a percentage, often 1% to 3%. It is a calculation based off of the annualized dividend payout of a stock compared to the stock price. Companies may pay dividends one quarter and skip the next, depending on their goals and financial situation.

Keep in mind that stock values don't always go up. Share prices can also fall, leaving investors with stocks worth (sometimes a lot) less than they paid for them. You can help decrease this risk by diversifying your investments and through a strategy called dollar-cost averaging, where you regularly invest a specific sum of money over time. When prices are low, you can afford to buy more shares. When they're high, you'll buy fewer.

That said, dollar-cost averaging does not assure a profit or protect against loss in declining markets.1

Types of stock

Publicly traded stock 

Publicly traded stock is probably what you have in mind when you think about stocks. It's the kind of stock typically purchased through brokerages and investment apps, and its price movements may be reported in the news.

A stock is "public" when its company lists it on a major exchange, like the New York Stock Exchange (NYSE) or Nasdaq. This enables everyday investors to buy and sell it, but it also opens companies up to more regulation. If companies are accessible to everyday investors, the Securities and Exchange Commission (SEC) requires that the companies disclose certain aspects of their finances to help investors make informed decisions.

Private companies can go public through processes like initial public offerings (IPOs) and direct listings, or if they are acquired by special purpose acquisition companies (SPACs).

Private stock

Private stock represents ownership in a private company. Unlike public stock, private stock can't easily be bought or sold through a normal brokerage account. Usually, any sale of private stock needs to be approved by the company itself.

Private stock is less commonly encountered by the typical investor, which can be a good thing. Private companies are much less regulated than public ones and have no obligation to inform the public of their financial health, making it harder for outsiders to judge investment potential. If you work for a private company, however, you may receive private stock as part of your benefits or compensation package.

Common stock 

Common stock is the "average joe" of equity. It's the public and private stock type you're most likely to buy and sell.

Common stock represents ownership of a company and gives the shareholder voting rights, letting them influence that company's future. A stock derives value based on the fundamentals of the company and market forces. Return on investment can be broken down to appreciation and dividends.

Common stockholders are the last people—behind bond holders, preferred stockholders, and other debt holders—to be compensated if a company goes bankrupt and must sell its holdings.

Preferred stock

Preferred stocks are like a mix between a common stock and a bond. They can offer predictable income through fixed dividends—like a bond might with interest payments—that are typically paid at regular intervals. Their shares also grant you ownership of a company like common stocks and may appreciate in value as the company becomes more desirable. And "convertible preferred stock" may be converted to common shares by the company or by you if certain conditions are met.

Unlike common stocks, preferred stocks don't come with shareholder voting rights. Another difference: Preferred shareholders always receive dividends and asset payouts before holders of common shares.

Growth stock

Growth stocks are shares of companies that investors expect to grow sales or earnings faster than the market average. Usually, growth stocks belong to smaller, newer companies that have a lot of potential but (at least in the moment) not a lot of profit. Growth stocks typically don't pay dividends, as the companies may prefer to invest extra cash in themselves to grow faster.

Growth stocks tend to have relatively higher stock prices compared to their earnings. When you buy one, you're hoping that company's growth exceeds current expectations, which can drive the share price up. There's no guarantee that a growth company will get there. And if it doesn't, investor favor may fade, sending prices down. This makes them riskier investments.

Value stock

Value stocks are associated with companies that investors think trade below what they're really worth based on their earnings, and tend to have relatively lower stock prices compared to their earnings. They tend to be larger, more established companies with solid financial histories. Some even pay dividends.

If you own a value stock, you're hoping the market eventually realizes the stock is undervalued, and its price bounces up. If it doesn't, you may be left holding a stock with good financial fundamentals but that never realizes its potential.

Income stock

Unlike growth or value stocks, investors who buy income stocks are focused on income, generating profit primarily from dividend payments. Share price appreciation is an added bonus.

Income investing can be risky because companies can reduce their dividend or choose not to pay one at any time. To help decrease that risk, income investors focus on companies' dividend history, making sure they've consistently paid or raised their dividend even in down markets.

How to buy stocks

These days, you can buy stocks by opening a brokerage (or regular investment) account online. Picking a broker is an important decision that you shouldn't take lightly. You may want a firm that won't hold you back with fees, hidden costs, or a lack of investment availability. For more information, check out our guide on where to open a trading account.

Once you have an account, your next move is to research stocks you may want to buy. Check out these 4 steps to picking your investments. And remember: You don't have to stick with buying individual shares. Mutual funds and exchange-traded funds (ETFs) can provide easy access to hundreds of different stocks at once, providing broad market exposure.

Investing involves risk, including risk of loss.

Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments. Investing in stock involves risks, including the loss of principal.

Past performance is no guarantee of future results.

Preferred securities are subject to interest rate risk. (As interest rates rise, preferred securities prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Preferred securities also have credit and default risks for both issuers and counterparties, liquidity risk, and, if callable, call risk. Dividend or interest payments on preferred securities may be variable, be suspended or deferred by the issuer at any time, and missed or deferred payments may not be paid at a future date. If payments are suspended or deferred by the issuer, the deferred income may still be taxable. See your tax advisor for more details. Most preferred securities have call features that allow the issuer to redeem the securities at its discretion on specified dates, as well as upon the occurrence of certain events. Other early redemption provisions may exist, which could affect yield. Certain preferred securities are convertible into common stock of the issuer; therefore, their market prices can be sensitive to changes in the value of the issuer's common stock. Some preferred securities are perpetual, meaning they have no stated maturity date. In the case of preferred securities with a stated maturity date, the issuer may, under certain circumstances, extend this date at its discretion. Extension of maturity date will delay final repayment on the securities. Before investing, please read the prospectus, which may be located on the SEC's EDGAR system, to understand the terms, conditions, and specific features of the security.

Growth stocks can perform differently from the market as a whole and other types of stocks, and can be more volatile than other types of stocks.

Value stocks can perform differently from other types of stocks, and can continue to be undervalued by the market for long periods of time.

Exchange-traded products (ETPs) are subject to market volatility and the risks of their underlying securities, which may include the risks associated with investing in smaller companies, foreign securities, commodities, and fixed income investments. Foreign securities are subject to interest rate, currency exchange rate, economic, and political risks, all of which are magnified in emerging markets. ETPs that target a small universe of securities, such as a specific region or market sector, are generally subject to greater market volatility, as well as to the specific risks associated with that sector, region, or other focus. ETPs that use derivatives, leverage, or complex investment strategies are subject to additional risks. The return of an index ETP is usually different from that of the index it tracks because of fees, expenses, and tracking error. An ETP may trade at a premium or discount to its net asset value (NAV) (or indicative value in the case of exchange-traded notes). The degree of liquidity can vary significantly from one ETP to another and losses may be magnified if no liquid market exists for the ETP's shares when attempting to sell them. Each ETP has a unique risk profile, detailed in its prospectus, offering circular, or similar material, which should be considered carefully when making investment decisions.
