What are Stocks? - Investopedia


The Definition of a Stock
Plain and simple, stock is a share in the ownership of a company. Stock represents a claim on the company's assets and earnings. As you acquire more stock, your ownership stake in the company becomes greater. Whether you say shares, equity, or stock, it all means the same thing.

Being an Owner
Holding a company's stock means that you are one of the many owners (shareholders) of a company and, as such, you have a claim (albeit usually very small) to everything the company owns. Yes, this means that technically you own a tiny sliver of every piece of furniture, every trademark, and every contract of the company. As an owner, you are entitled to your share of the company's earnings as well as any voting rights attached to the stock.

Risk
It must be emphasized that there are no guarantees when it comes to individual stocks. Some companies pay out dividends, but many others do not. And there is no obligation to pay out dividends even for those firms that have traditionally given them. Without dividends, an investor can make money on a stock only through its appreciation in the open market. On the downside, any stock may go bankrupt, in which case your investment is worth nothing.

Although risk might sound all negative, there is also a bright side. Taking on greater risk demands a greater return on your investment. This is the reason why stocks have historically outperformed other investments such as bonds or savings accounts. Over the long term, an investment in stocks has historically had an average return of around 10-12%.


Different Types of Stocks

Common Stock
Common stock is, well, common. When people talk about stocks they are usually referring to this type. In fact, the majority of stock is issued is in this form. We basically went over features of common stock in the last section. Common shares represent ownership in a company and a claim (dividends) on a portion of profits. Investors get one vote per share to elect the board members, who oversee the major decisions made by management.

Over the long term, common stock, by means of capital growth, yields higher returns than almost every other investment. This higher return comes at a cost since common stocks entail the most risk. If a company goes bankrupt and liquidates, the common shareholders will not receive money until the creditors, bondholders and preferred shareholders are paid.

Preferred Stock
Preferred stock represents some degree of ownership in a company but usually doesn't come with the same voting rights. (This may vary depending on the company.) With preferred shares, investors are usually guaranteed a fixed dividend forever. This is different than common stock, which has variable dividends that are never guaranteed. Another advantage is that in the event of liquidation, preferred shareholders are paid off before the common shareholder (but still after debt holders). Preferred stock may also be callable, meaning that the company has the option to purchase the shares from shareholders at anytime for any reason (usually for a premium).

Some people consider preferred stock to be more like debt than equity. A good way to think of these kinds of shares is to see them as being in between bonds and common shares.


Different Classes of Stock
Common and preferred are the two main forms of stock; however, it's also possible for companies to customize different classes of stock in any way they want. The most common reason for this is the company wanting the voting power to remain with a certain group; therefore, different classes of shares are given different voting rights. For example, one class of shares would be held by a select group who are given ten votes per share while a second class would be issued to the majority of investors who are given one vote per share.

When there is more than one class of stock, the classes are traditionally designated as Class A and Class B. Berkshire Hathaway (ticker: BRK), has two classes of stock. The different forms are represented by placing the letter behind the ticker symbol in a form like this: "BRKa, BRKb" or "BRK.A, BRK.B".


How Stocks Trade

Most stocks are traded on exchanges, which are places where buyers and sellers meet and decide on a price. Some exchanges are physical locations where transactions are carried out on a trading floor. You've probably seen pictures of a trading floor, in which traders are wildly throwing their arms up, waving, yelling, and signaling to each other. The other type of exchange is virtual, composed of a network of computers where trades are made electronically.

The purpose of a stock market is to facilitate the exchange of securities between buyers and sellers, reducing the risks of investing. Just imagine how difficult it would be to sell shares if you had to call around the neighborhood trying to find a buyer. Really, a stock market is nothing more than a super-sophisticated farmers' market linking buyers and sellers.

Before we go on, we should distinguish between the primary market and the secondary market. The primary market is where securities are created (by means of an IPO) while, in the secondary market, investors trade previously-issued securities without the involvement of the issuing-companies. The secondary market is what people are referring to when they talk about the stock market. It is important to understand that the trading of a company's stock does not directly involve that company.

The New York Stock Exchange
The most prestigious exchange in the world is the New York Stock Exchange (NYSE). The "Big Board" was founded over 200 years ago in 1792 with the signing of the Buttonwood Agreement by 24 New York City stockbrokers and merchants. Currently the NYSE, with stocks like General Electric, McDonald's, Citigroup, Coca-Cola, Gillette and Wal-mart, is the market of choice for the largest companies in America.

The trading floor of the NYSE
The NYSE is the first type of exchange (as we referred to above), where much of the trading is done face-to-face on a trading floor. This is also referred to as a listed exchange. Orders come in through brokerage firms that are members of the exchange and flow down to floor brokers who go to a specific spot on the floor where the stock trades. At this location, known as the trading post, there is a specific person known as the specialist whose job is to match buyers and sellers. Prices are determined using an auction method: the current price is the highest amount any buyer is willing to pay and the lowest price at which someone is willing to sell. Once a trade has been made, the details are sent back to the brokerage firm, who then notifies the investor who placed the order. Although there is human contact in this process, don't think that the NYSE is still in the stone age: computers play a huge role in the process.



The Nasdaq
The second type of exchange is the virtual sort called an over-the-counter (OTC) market, of which the Nasdaq is the most popular. These markets have no central location or floor brokers whatsoever. Trading is done through a computer and telecommunications network of dealers. It used to be that the largest companies were listed only on the NYSE while all other second tier stocks traded on the other exchanges. The tech boom of the late '90s changed all this; now the Nasdaq is home to several big technology companies such as Microsoft, Cisco, Intel, Dell and Oracle. This has resulted in the Nasdaq becoming a serious competitor to the NYSE.

On the Nasdaq brokerages act as market makers for various stocks. A market maker provides continuous bid and ask prices within a prescribed percentage spread for shares for which they are designated to make a market. They may match up buyers and sellers directly but usually they will maintain an inventory of shares to meet demands of investors.

Other Exchanges
The third largest exchange in the U.S. is the American Stock Exchange (AMEX). The AMEX used to be an alternative to the NYSE, but that role has since been filled by the Nasdaq. In fact, the National Association of Securities Dealers (NASD), which is the parent of Nasdaq, bought the AMEX in 1998. Almost all trading now on the AMEX is in small-cap stocks and derivatives.

There are many stock exchanges located in just about every country around the world. American markets are undoubtedly the largest, but they still represent only a fraction of total investment around the globe. The two other main financial hubs are London, home of the London Stock Exchange, and Hong Kong, home of the Hong Kong Stock Exchange. The last place worth mentioning is the over-the-counter bulletin board (OTCBB). The Nasdaq is an over-the-counter market, but the term commonly refers to small public companies that don’t meet the listing requirements of any of the regulated markets, including the Nasdaq. The OTCBB is home to penny stocks because there is little to no regulation. This makes investing in an OTCBB stock very risky.
