You're not alone if you're apprehensive about investing in the stock market. Inexperienced investors are either frightened by stories of investors losing half their portfolio value or enthralled by "hot ideas" that promise great rewards but rarely deliver on their promises. As a result, it is understandable that the investment emotion pendulum swings between a fearful and greedy state.

When addressed in a systematic manner, investing in the stock market can be one of the most effective ways to enhance one's net worth. While the majority of the average person's wealth is held in their home, the affluent and very wealthy tend to put most of their money in the stock market. 1. First, let's examine the definition and classification of stocks in order to gain a better understanding of how the stock market works.



The most important points:

  • Stocks represent ownership equity in the firm and give shareholders voting rights as well as a residual claim on corporate earnings in the form of capital gains and dividends.
  • Individual and institutional investors come together on stock exchanges to buy and sell shares in a public venue.
  • Share prices are set by supply and demand as buyers and sellers place orders.
  • Order flow and bid-ask spreads are often maintained by specialists or market makers to ensure an orderly and fair market.
  • Listing on exchanges may provide companies with liquidity and the ability to raise capital but it can also mean higher costs and increased regulation.


What Are Stocks?

A stock is a form of ownership in a company or corporation. It gives the owner a claim on the company's assets (what it owns) and earnings (what it generates in profits). Shares or equity are other names for stocks. When a person owns stock, they own a piece of the company equal to the number of shares they own as a percentage of the company's total shares. For example, a person or group that owns 100,000 shares of a company with 1,000,000 shares in circulation has a 10% stake in that company. Most companies have millions or billions of shares that are still being used.

Types of Stock

Stock can be divided into two primary categories: common shares and preference shares. Since common shares have a far higher market value and trading volume than preferred shares do, the term "equities" is often used to refer to them. 

The primary difference between the two is that, whereas preferred shares typically do not have voting rights, common shares typically do, allowing common shareholders to participate in company meetings and elections. The reason why preferred shares are thus titled is because preferred shareholders receive dividends and assets before common stockholders in the event of a liquidation. 

The voting rights of common stock can be used to further categorise them. While the fundamental idea behind common shares is that each share should have an equal number of votes (one vote per share held), some businesses have dual or multiple classes of stock, each of which has a separate set of voting rights. In a dual-class arrangement like this, Class A shares may each have ten votes whereas Class B shares could only have one. Dual- or multiple-class share structures are made to provide a company's founders influence over its finances, strategic course, and capacity for innovation. 

Why Companies Issue Shares

Many of the large corporations of today were once begun as visionary founders' tiny, private businesses. Consider how Jack Ma started Alibaba (BABA) from his Hangzhou, China, apartment in 1999 or how Mark Zuckerberg started the first Facebook (now Meta) from his dorm room at Harvard University in 2004. 45

Within a few decades, companies like these technology behemoths rose to the ranks of the largest in the world.

However, such rapid growth necessitates the availability of enormous amounts of capital. An entrepreneur needs to do a number of things before their idea may go from their head to a functioning business, including renting space for an office or factory, hiring staff, purchasing raw materials and equipment, and setting up a sales and distribution network. Depending on the size and breadth of the company, these resources need a considerable investment.

Raising Capital

A new business can get this kind of money by selling shares or by taking loans (debt financing). Debt financing can be hard for a new company to get because it may not have many assets to put up as collateral for a loan. This is especially true in fields like technology and biotechnology, where companies have few tangible assets. Also, the interest on the loan would be a financial burden in the beginning, when the company may not have any sales or income.

So, equity financing is the best way for most startups to get the money they need. To get the business off the ground, the entrepreneur may use his or her own savings or ask friends and family for money. As the business grows and needs more money, the entrepreneur may look to angel investors or venture capital firms for help.

Listing Shares

When a business is getting started, it may need more funds than it can get from its regular operations or a traditional bank loan. It can do this by selling shares to the public through a "IPO" (IPO).

This makes the company go from being a private company whose shares are only owned by a few people to a publicly traded company whose shares will be owned by many people in the general public. The IPO also gives early investors in the company a chance to cash out some of their shares, which is often a very profitable move.

Once a company's shares are listed on a stock exchange and trading begins, the price of these shares goes up and down as investors and traders try to figure out how much they are really worth. There are many ratios and metrics that can be used to value stocks, but the price-to-earnings (PE) ratio is probably the most popular one. Stock analysis also tends to fall into one of two groups: fundamental analysis or technical analysis.

What Is a Stock Exchange?


History of Stock Exchanges

In the 16th and 17th centuries, port cities and trading hubs like Antwerp, Amsterdam, and London were where the first stock markets were set up. 6 But these early stock exchanges were more like bond exchanges because the few companies that traded on them did not issue equity. In fact, most of the first corporations were considered semi-public organisations because they needed permission from their government to do business.

At the end of the 18th century, stock markets like the New York Stock Exchange (NYSE) started to pop up in America. These markets let people trade equity shares. The Philadelphia Stock Exchange (PHLX), which still exists today, was the first stock exchange in the United States. 7 In 1792, 24 stockbrokers and merchants from New York City signed the Buttonwood Agreement. This was the start of the NYSE. Before this official incorporation, traders and brokers would meet unofficially under a buttonwood tree on Wall Street to buy and sell shares. 8

Modern stock markets brought with them a new era of rules and professionalism that makes it possible for buyers and sellers of shares to be sure their deals will go through at fair prices and in a reasonable amount of time. There are many stock exchanges in the U.S. and around the world today, and many of them are linked together electronically. In turn, this means that markets are more efficient and have more money in them.

Largest Stock Exchanges

There have been stock exchanges for more than 200 years. The NYSE has been around for a long time. It began in 1792, when a group of 24 brokers got together in Lower Manhattan and made a deal to trade securities on commission. 8 In 1817, New York stockbrokers who had been working under the agreement made some important changes and changed their name to the New York Stock and Exchange Board. 17

Based on the total market capitalization of all the companies listed on each exchange, the NYSE and the Nasdaq are the two largest exchanges in the world. Nearly two dozen U.S. stock exchanges are registered with the Securities and Exchange Commission. However, most of these are owned by Cboe Global Markets, Nasdaq, or Intercontinental Exchange, which also owns the New York Stock Exchange. 18

The table below shows the total market capitalization of the companies listed on the 20 largest exchanges in the world.

How Do People Lose Money in the Stock Market?

Most people who lose money on the stock market do so because they bought high-risk stocks without thinking. Even though these can make a lot of money if they work, they are also just as likely to lose money. There is also a psychological factor: an investor who sells during a crash will lock in their losses, while an investor who keeps their stock has a chance of getting rewarded for their patience. Lastly, trading on margin can make the stock market even more risky by making gains or losses bigger.
