When it comes to the United States stock market, there are several major exchanges that play a significant role. Each of these exchanges has its unique characteristics, making them appealing to different types of investors. In this article, we will explore the differences between the largest US stock markets: the New York Stock Exchange (NYSE), the NASDAQ, and the American Stock Exchange (AMEX).
The New York Stock Exchange (NYSE)
Established in 1792, the NYSE is the oldest and most famous stock exchange in the United States. It is located in Lower Manhattan, New York City. The NYSE is home to many of the largest and most well-known companies in the world, including ExxonMobil, Procter & Gamble, and Johnson & Johnson.
One of the key distinctions of the NYSE is its trading floor, where traders and brokers physically meet to execute trades. This traditional method of trading has been a hallmark of the NYSE for centuries. Additionally, the NYSE is known for its strict listing requirements, ensuring that only the most reputable companies are listed on its exchange.
The NASDAQ Stock Market
In contrast to the NYSE, the NASDAQ Stock Market is a fully electronic exchange that operates 24 hours a day, 5 days a week. Established in 1971, the NASDAQ is the second-largest stock exchange in the United States by market capitalization. It is home to many of the fastest-growing companies, including Apple, Microsoft, and Facebook.
One of the main advantages of the NASDAQ is its flexibility. The electronic trading platform allows for faster execution of trades and lower transaction costs. Additionally, the NASDAQ has relatively lenient listing requirements, making it an attractive option for technology and biotechnology companies.
The American Stock Exchange (AMEX)
The AMEX is the smallest of the three major US stock exchanges. It was acquired by the NYSE in 1998 and is now known as NYSE American. The AMEX is home to many small and mid-cap companies, as well as some well-known names like American Airlines and Whole Foods Market.
One of the key distinctions of the AMEX is its focus on smaller companies. The exchange offers a more accessible platform for these companies to raise capital and increase their visibility. The AMEX also has a reputation for being more accommodating to smaller and emerging companies.
Case Study: Apple

To illustrate the differences between these exchanges, let's consider the case of Apple Inc. When Apple went public in 1980, it was listed on the NASDAQ. The company's innovative technology and rapid growth were well-suited to the NASDAQ's electronic trading platform and lenient listing requirements.
However, as Apple continued to expand, it eventually moved to the NYSE in 2012. The NYSE's reputation and traditional trading floor provided a more prestigious platform for the world's largest technology company. This move also reflected Apple's desire to align itself with the largest and most well-known companies on the exchange.
In conclusion, the largest US stock markets—NYSE, NASDAQ, and AMEX—offer distinct advantages and cater to different types of investors and companies. Understanding these differences can help investors make informed decisions when selecting where to list their companies or where to invest their capital.
