What are stocks?
Get a better understanding of how you can incorporate stocks into your trading or investing strategy by learning what stocks are, the types of stocks available (including U.S. common stocks), and how to invest in the U.S. stock market.
How do stocks work?
A stock represents a share in the ownership of a company, including a claim on the company's earnings and assets. As such, stockholders are partial owners of the company. When the value of the business rises or falls, so does the value of the stock.
Transactions happen on stock exchanges
Investors generally buy and sell stocks electronically through stock exchanges — the two primary ones in the United States being the New York Stock Exchange (NYSE) and the National Association of Securities Dealers Automated Quotations (NASDAQ). While some companies sell stock directly to investors, most only sell stock through a brokerage such as Schwab.
Why do investors buy and sell stocks?
Investors buy and sell stocks for many reasons. They may be seeking to:
- Grow the value of their investable assets over time
- Profit from shorter-term stock price moves
- Earn income by investing in dividend-paying stocks
The reasoning behind these decisions is often derived from qualitative and quantitative techniques like fundamental analysis or technical analysis.
Keep in mind:
- The price of a stock can fall as easily as it can rise.
- Investing in stock offers no guarantee that you will make money, and many investors lose money instead.
- Payment of stock dividends is not guaranteed and dividends may be discontinued.
- The underlying common stock is subject to market and business risks, including insolvency.
Types of stocks.
Learn about three main types of stocks, as well as some potential advantages and considerations.

Definition>Common stock>
A stock represents a share in the ownership of a company, including a claim on the company's earnings and assets. As such, stockholders are partial owners of the company.
Fractional shares of stock also represent ownership of a company but at a size smaller than a full share of a U.S. common stock.
Preferred stock2Preferred stocks (or preferred securities) are hybrid investments that share characteristics of both stocks and bonds. They can offer higher yields than many traditional fixed income investments, but they come with different risks.>American Depositary Receipts (ADRs)>Many non-U.S. companies, that would otherwise be unavailable or inconvenient to trade, do trade in the U.S. markets as ADRs (receipts for shares of the foreign stock issued by U.S. banks). They are denominated in U.S. dollars and pay dividends in U.S. dollars.
-
Advantages>Common stock>
Potential for higher long-term return.
Voting rights (does not apply to owners of fractional shares).
Liquidity depending on trading volume.
Preferred stock2>Dividends are typically higher and fixed.
Share price experiences less volatility compared to common stock.
Preferred shareholders are more likely to recover at least part of their investment if the company goes bankrupt.
American Depositary Receipts (ADRs)>Allows investors to buy and sell shares of non-U.S. companies on US exchanges denominated in USD.
Dividends are paid out in USD.
Investors may be able to access financial information more easily with ADRs than for direct investments overseas.
-
Risk Considerations>Common stock>
Dividends, if available, are often lower, variable, and not guaranteed.
Stock price and dividend may experience more volatility than preferred stock.
More likely to lose investment if the company goes bankrupt.
Preferred stock2>Lower long-term growth potential, if any.
No voting rights in most cases.
Generally less liquid than common stock.
American Depositary Receipts (ADRs)>Exposure to fluctuations in a foreign company's local currency could affect value of investments.
Political or economic events in a foreign company's home country could potentially harm your investment.
Key concepts investors should understand.
Knowing the following concepts can help you trade or invest in the U.S. stock market.
Value and growth stocks
Value and growth stocks are two different types of stock.
- Growth stocks: Growth stocks are generally shares issued by companies that are expanding or viewed as positioned for expansion. Such companies typically reinvest earnings in business rather than distribute them as dividends, and investors generally buy them for potential capital appreciation rather than dividend income.
- Value stocks: These stocks typically trade at relatively low valuations compared with company fundamentals, such as earnings, sales, and dividends. Investors may view these stocks as undervalued based on such measures, although this classification does not mean that the securities are objectively underpriced.
Stock dividends
Stock dividends are a payment in the form of additional shares instead of cash. For some investors, dividends can help support portfolio growth potential or provide additional income. Please note that dividend payments are not guaranteed.
Sector investing
Sector investing is the strategy of investing across an entire sector (e.g., technology, financial, consumer staples, etc.), typically using exchange-traded funds (ETFs). This approach can help investors focus on areas of the market they believe may offer growth opportunities.
Fractional shares
A fractional share represents less than one full share of ownership in a company. Fractional shares allow you to place an order based on the dollar amount you want to invest, so you may end up with a fraction of a share, a whole share, or more than one share. Please note that fractional shares may carry different rights than full shares, including limited voting rights and restrictions on transfer or liquidation.
Stock split
A stock split is a type of corporate action that occurs when a company's board of directors decides to divide the company's outstanding shares into a larger or smaller number of shares. Splits are a change in the number of outstanding shares of a company's stock without a change in shareholders' ownership percentage in the company. For example, with a 2:1 split, a shareholder will receive two shares for each share owned prior to and through the open on the security's split ex-dividend (or "effective") date. Also, the share price is adjusted so the value of one's holding in the split stock is unchanged, absent any price changes post-split.

Common questions about stocks.
-
Value and growth stocks are two different types of stock. Growth stocks are anticipated to grow at a rate above the average for the market. Value stocks are those that tend to trade at a lower price relative to their fundamentals. To determine whether a stock is underpriced, market analysts look at a company's fundamentals (such as dividends, earnings, and sales) relative to its current share price. Growth stocks tend to be more volatile investments and generally do not pay dividends.

Stock dividends are a payment in the form of additional shares, instead of cash.

Splits are a change in the number of outstanding shares of a company's stock without a change in shareholders' ownership percentage in the company. For example, with a 2:1 split, a client will receive two shares for each share owned prior to and through the open on the security's split ex-dividend (or "effective") date. Also, the share price is adjusted so the value of ones holding in the split stock is unchanged, absent any price changes post-split.

People invest in stocks for different reasons—growing the value of their investable assets, profiting from short-term price moves, or earning income from dividends. Over time, owning stocks can help build wealth in a few key ways: When the value of a company grows, the value of its stock may increase, allowing investors to benefit from that appreciation. For investors who reinvest dividends, compounding can further accelerate portfolio growth—earnings generate additional earnings over time. Of course, remember that investing in stock offers no guarantee that you will make money and that it's possible to lose money and payment of stock dividends is not guaranteed. As with any investment, it helps to weigh the benefits and risks and consider how stocks might fit into your overall portfolio.

Investors can gain exposure to international companies through U.S. markets by investing in Schwab's American Depositary Receipts (ADRs). ADRs are securities issued by U.S. banks that represent shares of non-U.S. companies and trade on U.S. exchanges in U.S. dollars. This allows investors to buy and sell shares of certain international companies through a U.S. brokerage account without trading directly on foreign exchanges. Learn more about ADRs.
