What is Stock Market and How does it work?

A stock market is a place where investors(we people) trade certificates that indicate partial ownership in businesses for a set price. Through these transactions, companies can raise the initial capital necessary for various aspects of operation, and those who buy the certificates become entitled to a portion of the business' assets and earnings. Although the value of the certificates is not static and depends to a large extent on public perception, the stock market remains one of the major means of investment and can be used as an indicator of overall economic health.

Stocks and Shares

When companies need money for various goals, one option they have for getting capital (money) is to divide ownership of their businesses up into parts known as SHARES. They sell these shares and use the funds for tasks like developing products or buying buildings and equipment. To provide some proof of this ownership division, they print certificates called STOCK, and individuals who purchase the certificates are called stockholders. Many people use the words "stocks" and "shares" — or similarly, "stockholder" and "shareholder" — interchangeably because of their close relationship, but the former term technically talks about certificates for all companies in a very general sense, and the latter usually connects to a single, specific business.

As partial owners in a company, shareholders are entitled to a percentage of the assets and earnings for the business. They usually hope that the business in which they have invested will make money, because then they will receive some of the profits — in fact, the basic goal usually is to buy stock when the price is low and sell it when the value is high. With common stock, they also usually have voting rights, typically getting one vote on company issues for every certificate they own, and they generally receive annual or quarterly reports that let them know how the company is doing financially. Preferred stocks don't usually give voting rights, but they many people like them because they give more of the earnings and assets to the shareholders, and because they give investors payment priority if the company goes bankrupt and ends what it owns.

Purpose of the Market

At the most basic level, the stock market provides an organized way for businesses to connect with potential investors who might want to purchase stocks and become partial owners. When a corporation wants to sell shares of its company, it usually lists its stock on an exchange, which is an organization that hosts all the activities related to buying and selling certificates. A business typically has to meet specific requirements to get on an exchange, so investors usually see them as less risky when compared to businesses that sell "over the counter" (OTC), or without being listed. The New York Stock Exchange (NYSE) and the National Association of Securities Dealers (NASDAQ) are commonly used stock exchanges in the United States.

Basic Sales Process

When individuals are interested in buying or selling stock, they usually contact a stock broker, who is a person who works at a firm authorized to trade at stock exchanges. He relays the trade message to the floor of the correct exchange, usually receiving a commission for his service, and a representative of the company then completes the trade request. In the past, the floor was a physical place on the exchange where stock brokers met to carry out sale and purchase transactions, but today, virtual, electronic floors using the Internet or phone interactions are much more common.
A common misconception is that a person has to have a lot of money to go through this process. An individual does need to weigh the potential for earnings against the fee to buy, but many stocks are relatively inexpensive and provide good returns over the long term, and because brokers get a commission on each trade, they're usually willing to complete transactions handling a fairly low number of certificates. Additionally, many people pool their resources into what's called a mutual fund, which allows investors to work together to buy more or pricier stocks.

Stock Value

The value of a stock is determined initially when a company holds an event called an Initial Public Offering (IPO), during which an investment bank uses various complex techniques and formulas to estimate how much the company is worth. The business then divides this valuation by the number of shares it wants to offer. After this, however, the worth of stock certificates depends to a large degree on public perception. Under the basic principles of supply and demand, when people think the company isn't doing well, they usually don't want to buy the stock certificates, and demand for them goes down, reducing their value. Conversely, if the public thinks the business is successful and will have profits and assets to divide up, investors typically want to purchase the stocks, and the certificate demand and value goes up.
