The NASDAQ-100 is a stock market index comprised of 100 of the largest non-financial companies listed on the Nasdaq stock exchange. Launched on January 31, 1985, it includes companies from various sectors such as technology, retail, telecommunications, healthcare, and media. However, it excludes financial companies, which are tracked in a separate index called the Nasdaq Financial-100. The index is modified capitalization-weighted, meaning that larger companies have a greater impact on the index's value. To be included in the NASDAQ-100, companies must meet specific criteria, including being listed exclusively on Nasdaq, having been publicly offered for at least three months, and maintaining an average daily trading volume of 200,000 shares.
The NASDAQ-100 is re-ranked annually to ensure that the largest non-financial companies on Nasdaq are accurately represented. As of September 2, 2025, the technology sector makes up the largest portion of the index at 62.48%, followed by Consumer Discretionary (18.62%). While the index is limited to 100 issuers, some may have multiple classes of shares, resulting in more than 100 stocks in the index. Products tied to the NASDAQ-100 are available in 28 countries, and derivatives tied to the index have a notional value of over $1 trillion. The index is often abbreviated as NDX, NDQ, NAS100, or US100 in the derivatives markets, and its futures contracts are heavily traded on the Chicago Mercantile Exchange. As of February 10, 2026, the NASDAQ-100's price ranged from 24,876.28 to 25,337.54.
