Effective October 3, 2005, The all-share index of Tallinn Stock Exchange (TALSE) was renamed to OMX Tallinn (OMXT), according to SEB.
The change is part of OMX’s strive to create an integrated and efficient Nordic Baltic marketplace. The new OMX index name structure covers all-share, tradable, benchmark and sector indexes. The name structure is constructed around the OMX name, the specific stock exchange and the index of choice.
The all-share index of Stockholm Stock Exchange is OMX Stockholm (OMXS), for Copenhagen Stock Exchange it is OMX Copenhagen (OMXC) and for Helsinki Stock Exchange it is OMX Helsinki (OMXH). New index names for the Baltic exchanges are similar: the all-share index of Tallinn Stock Exchange (TALSE) was renamed to OMX Tallinn (OMXT), the all-share index of Riga Stock Exchange (RIGSE) was renamed to OMX Riga (OMXR) and the all-share index of Vilnius Stock Exchange (VILSE) was renamed to OMX Vilnius (OMXV). Only the name of the Baltic main list index BALTIX remained the same.
Danish tradable index KFX was renamed to OMXC20, in line with tradable indices in Stockholm and Helsinki (OMXS30 ja OMXH25). The benchmark indexes in Copenhagen and Stockholm were changed to OMXCB and OMXSB, respectively, in line with the name of the Helsinki benchmark index OMXHB. Sector, industry group and industry indexes were harmonized accordingly.
To date the index harmonization process has included rule harmonization, implementation of GICS classification standard, developed by MSCI and Standard & Poor’s, a new benchmark and sector indexes in Helsinki and the introduction of a new index calculation system. The harmonization of the index names started last autumn, with the change of the tradable index names in Stockholm and Helsinki into OMX Stockholm 30 and OMX Helsinki 25.
