A stock exchange serves as a crucial marketplace where securities, such as company shares and municipal bonds, are bought and sold. These platforms facilitate investment and capital formation, playing a vital role in modern capitalist economies by providing liquidity for investors and enabling businesses to raise capital.

What is a Stock Exchange?

Initially, stock exchanges offered open access for anyone wishing to trade corporate securities. However, it quickly became apparent that organized associations were essential for efficient and reliable transactions. Today, membership in stock exchanges is typically restricted to limited clubs or associations.

Stock exchanges are indispensable to a capitalist economy. While investment bankers handle the initial sale of corporate securities, stock exchanges then provide ongoing markets for these securities. This allows original investors to sell their holdings as needed, which in turn encourages further investment.

Major Global Stock Exchanges

The world's most prominent stock exchanges include the New York Stock Exchange (NYSE), the London Stock Exchange (LSE), and the Tokyo Stock Exchange (TSE). Another significant, though less regulated, exchange is the National Association of Securities Dealers Automated Quotation (NASDAQ).

NASDAQ operates as an automated (computerized) marketplace, connecting dealers across the United States and, to a lesser extent, in Europe. It is the second-largest and fastest-growing U.S. stock market, facilitating the trading of over-the-counter (OTC) securities, often issued by less-established companies, alongside shares of major corporations like Microsoft.

The Rise of Digital and Automated Trading

NASDAQ exemplifies a broader trend towards increased competition and the adoption of mechanized trading methods, replacing traditional stock exchange floors where brokers and dealers once met for open outcry trading. A significant transformation occurred in October 1986, known as the "Big Bang," when the London Stock Exchange transitioned entirely to a computer-based system. This change allowed dealers to view all prices instantly on display monitors.

In contrast to NASDAQ and the LSE, the New York Stock Exchange has largely maintained its traditional trading floor system. However, even established national exchanges have faced growing competition from new computerized trading systems developed by private firms. With advancements in information technology and high-speed computing, the cost of providing national stock markets via computer screens has significantly decreased.

The use of diverse trading systems can potentially reduce transaction costs and sometimes bypass certain regulations imposed by established exchanges. For instance, it's possible to buy and sell French shares on the Indian stock market using systems like the Stock Exchange Automated Quotation International (SEAQ International). SEAQ International has been remarkably successful in capturing market share from local stock exchanges in many countries, to the extent that for some nations, a greater volume of trades occurs on NASDAQ than on their own domestic exchanges.

Understanding Stock Trading Systems

Increased competition among exchanges has led to the division of trading systems into two broad categories:

Market Maker System

Leading exchanges like London, NASDAQ, and Paris utilize the market maker system. In this model, market makers determine the prices at which they are willing to buy and sell each share. Shareholders can observe these prices, and the market aims to facilitate the best possible deal for all participants – the highest price for sellers and the lowest for buyers. All rates are displayed on computer monitors, and market makers are committed to adjusting their rates for trades up to a normal market size (NMS). Rates above the NMS are indicative only, and the final deal with the market makers confirms the share price.

The benefits of this method include immediate execution of orders and price certainty at the time of the trade.

Auction System

The auction system is another common trading method. Here, all buy and sell orders from shareholders are collected and matched against each other, with the best deals finalized to clear the market. The Paris Bourse stock exchange is a prime example of an auction-based system. Auctions are typically computer-operated and can be continuous, or they can occur once or twice a day in what are known as batch auctions.

The main advantage of this system is its cost-effectiveness, as there are no fees for market maker services. However, a drawback is that it may not always be possible to trade immediately or at a precisely known cost
