FDN is designed to measure performance of the largest and most actively traded stocks of US internet companies. The index is a composite of two sub-indices involved in internet commerce and internet services. To be included in the index, 50% of its revenue must come from the Internet. Eligible securities are ranked first by three-month average float-adjusted market capitalization and then by three-month average share volume. A final rank is then calculated based on an equally weighted average of the securitys market capitalization and volume rankings. Securities are then sorted in descending order by final rank within their sub-industries, respectively. 15 securities from the Internet Commerce and 25 securities from the Internet Services with the best rankings are included. Securities are float-adjusted market capitalization weighted, subject to 10% cap for a single security. The aggregate weight of individual securities with weights of 4.5% or more is limited to 45% of the Index.
