What Is the Nasdaq-100 Index?

The Nasdaq-100 Index is one of the most widely followed stock market indexes in the world. Investors, financial analysts, and market commentators frequently discuss its performance because it contains many of the largest and most influential companies in modern technology.

As technology continues to shape the global economy, understanding the Nasdaq-100 has become increasingly important for investors. Whether you are interested in exchange-traded funds (ETFs), long-term investing, or technology stocks, learning about this index can help you better understand today's financial markets.

In this guide, we will explain what the Nasdaq-100 Index is, how it works, why investors follow it, and how individuals can gain exposure to its performance.

What Is the Nasdaq-100 Index?

The Nasdaq-100 Index is a stock market index that tracks 100 of the largest non-financial companies listed on the Nasdaq Stock Market.

The index includes companies from a variety of industries, such as:

  • Technology
  • Consumer services
  • Healthcare
  • Telecommunications
  • Industrial businesses

Unlike some other stock indexes, the Nasdaq-100 excludes financial companies such as banks and insurance firms.

Because many technology companies are included, the index is often viewed as a measure of innovation and growth within the economy.

Why Was the Nasdaq-100 Created?

The Nasdaq-100 was introduced in 1985.

Its purpose was to provide investors with a benchmark that represented the largest companies trading on the Nasdaq exchange.

Over time, the index became increasingly popular because many leading technology firms chose Nasdaq as their primary listing exchange.

As technology companies expanded, the Nasdaq-100 became closely associated with innovation and future growth.

How Does the Nasdaq-100 Work?

The index is market-cap weighted.

This means larger companies have a greater influence on the index than smaller companies.

Market capitalization is calculated by multiplying a company's stock price by its number of outstanding shares.

Companies with larger market values receive larger weights within the index.

As a result, movements in the largest companies can significantly affect overall index performance.
