Definition of the Stock Market

The stock market refers to the collection of exchanges and markets where stocks (also known as equities) are bought and sold. Stocks represent ownership in a company, giving shareholders a claim on the company's profits and assets.

The two primary types of markets are:

Primary Market: Where companies issue new shares through initial public offerings (IPOs) to raise capital.

Secondary Market: Where existing shares are traded among investors. Most stock trading happens in the secondary market.

How Does the Stock Market Work?

The stock market operates through a network of exchanges, which are centralized marketplaces where securities such as stocks, bonds, and other financial instruments are bought and sold. They provide a regulated and organized environment for investors and companies to trade efficiently, transparently, and securely. Some of the more well-known exchanges are the New York Stock Exchange (NYSE), NASDAQ, and London Stock Exchange (LSE).

How Does a Stock Exchange Function?

Companies List Shares

Businesses that want to raise funds go public by listing their shares on an exchange. This process is known as an initial public offering, or IPO. By selling shares, the company generates capital to fund operations, expand, or pay off outstanding debt.

Investors Buy and Sell Shares

Once shares are listed, they can be bought and sold on the exchange. Investors trade these shares based on their expectations of a company’s performance and its future business and financial prospects.

Prices Are Determined by Supply and Demand

Stock prices fluctuate based on supply and demand. If more people want to buy a stock than sell it, the price increases. Conversely, if more people want to sell than buy, the price drops.

Trading Facilitated by Brokers

Individual investors typically use brokerage platforms to access the stock market. Brokers act as intermediaries, executing trades on behalf of investors.

Market Hours and Sessions

Stock markets operate during specific hours, known as trading sessions. For example, the NYSE is open from 9:30 AM to 4:00 PM EST on business days.

Why Is the Stock Market Important?

The stock market plays a vital role in representing and stimulating the health of both investors and the economy.

Capital for Companies

By selling shares, companies can raise money to fund innovation, expand operations, or enter new markets.

Wealth Creation for Investors

Investors can grow their wealth by purchasing shares that increase in value over time or by earning income from dividends, which are a portion of a company’s profits distributed to its shareholders.

Economic Indicator

The stock market reflects the economic health of a country. Rising stock prices generally indicate investor confidence and economic growth, while falling prices may signal economic trouble.

Liquidity

The stock market provides liquidity, allowing investors to quickly and easily buy or sell shares in a centralized place.

A well-functioning stock market encourages people to invest their savings, which fuels economic growth.
