    Real-time and historical Index data for the diverse suite of Nasdaq and other Global Indexes.

    GIDS provides data recipients, either directly or through a third-party distributor, the opportunity to reduce network, administrative and data center costs by taking one data feed, rather than many. 

    GIDS also provides greater dissemination frequency for select indexes, allowing for better trading performance and portfolio valuations. The real-time feed also standardizes message formats for index and ETF values to facilitate the processing of cross-market data.


    Daily performance, NAV, valuation, and strategy-level reference data, such as fund asset focus, sector focus and expenses, for over 35,000 global investable products.

    The Nasdaq Fund Network (NFN) facilitates the collection and dissemination of performance, NAV, valuation, and strategy-level reference data for over 35,000 investable products to 100 million plus investors.

    Members of the service register their products on the network and receive a unique symbol. The service then disseminates the stock market data, making it searchable on one of the largest distribution channels, which pipes into online brokerages and major market data vendors.

    Product issuers and asset managers benefit from an automated service that helps bring more awareness to and gather assets for new and existing products. Also, both institutional and retail investors, as well as the general investing public, benefit from daily access to transparent fund-level data for a wide range of products to help inform investment decisions.
