NASDAQ-100
The NASDAQ-100 (NDX) is a stock market index comprising 100 of the largest non-financial companies listed on the Nasdaq Stock Market based on modified market capitalization. Introduced on 31 January 1985 by Nasdaq, Inc., the index is widely regarded as one of the principal benchmarks for the technology sector and growth-oriented equities in the United States. Unlike broader market indices, the NASDAQ-100 excludes companies primarily engaged in financial services, focusing instead on industries such as technology, consumer discretionary, healthcare, telecommunications, industrials, and consumer services. The index serves as a widely followed benchmark for institutional and retail investors and underlies numerous exchange-traded funds (ETFs), derivatives, and structured financial products.
The NASDAQ-100 is composed of eligible domestic and international non-financial companies listed on the Nasdaq Stock Market that meet specified requirements relating to market capitalization, liquidity, trading history, public float, and corporate governance. Constituents are weighted using a modified capitalization-weighted methodology designed to limit excessive concentration in the largest companies while preserving market representation. The index is rebalanced periodically and undergoes annual reconstitution to ensure continued compliance with eligibility criteria. Because of its concentration in large technology and innovation-driven companies, the NASDAQ-100 is widely used as an indicator of the performance of the U.S. technology and growth equity sectors.
The index serves as the underlying benchmark for numerous investment products, including the Invesco QQQ Trust, one of the world's largest exchange-traded funds, as well as futures, options, leveraged products, and structured investment instruments traded globally. It is extensively referenced by asset managers, institutional investors, analysts, and researchers for portfolio benchmarking, passive investment strategies, asset allocation, risk management, and market analysis. The NASDAQ-100 has also become an important benchmark for evaluating the performance of companies engaged in artificial intelligence, semiconductors, cloud computing, software, biotechnology, e-commerce, digital communications, and other innovation-driven industries.
The NASDAQ-100 is maintained by Nasdaq, Inc. and operates within the regulatory framework of the U.S. Securities and Exchange Commission (SEC). The index is widely followed alongside other major U.S. equity benchmarks, including the S&P 500, the Dow Jones Industrial Average, and the NASDAQ Composite. Data relating to the index are disseminated globally through financial information providers such as Bloomberg L.P., FactSet, Morningstar, Inc., S&P Global, and other market data vendors. Through its emphasis on large-cap, innovation-focused companies, the NASDAQ-100 has become one of the most influential stock market indices in global equity markets.
