Nasdaq Equities Symbology Initiative

The Nasdaq equities exchanges currently participate in the National Market System Symbology Plan for the selection and use of 1-5 character root symbols, as governed by ISRA, the Intermarket Symbols Reservation Authority.

Nasdaq believes that all market participants benefit from a uniform symbology solution covering the root symbol for primary securities and suffices for all subordinate issue types. As members of ISRA, The Nasdaq Stock Market, and Nasdaq PHLX will continue to work jointly with the Securities and Exchange Commission, industry participants, and related trade associations to develop a suffix plan that promotes fair competition, reduces programming and operational complexity, and upholds the interests of both listed issuers and market participants.

Find the latest information about ISRA and a copy of the NMS Symbology Plan on The Options Clearing Corporation's (The OCC) website by clicking here. The OCC acts as the ISRA processor for the National Market System Plan.
