Launched in January 1985, the Nasdaq-100 Index represents the largest and most active non-financial domestic and international issues listed on The Nasdaq Stock Market® based on market capitalization.

For a list of all 100 components of the Nasdaq-100, please visit here.

The Nasdaq-100 Index is calculated under a modified-capitalization-weighted methodology. The methodology is expected to retain in general the economic attributes of capitalization weighting while providing enhanced diversification. To accomplish this, Nasdaq will review the composition of the Nasdaq-100 Index on a quarterly basis and will adjust the weightings of Index components using a proprietary algorithm if certain pre-established weight distribution requirements are not met.
