Nikkei announced on Thursday that it will revise the rules governing its Nikkei 225 index, creating a new "information and communications" sector for constituent selection. The company will also rename the "communications" category in the Nikkei industry classification to "information and communications," move IT-related stocks from the services category to the new industry grouping, and introduce rules for replacing constituents within the same sector.
Under the constituent selection methodology for the Nikkei 225, the 36 subcategories in the Nikkei industry classification are grouped into six broader sectors. Constituent additions and deletions are determined with consideration given to maintaining balance among those sectors and avoiding excessive concentration in any one area. The creation of the information and communications sector will increase the number of sectors to seven.
The rule changes were decided after taking into account feedback received during a consultation conducted in May and June. The new rules will take effect on Oct. 1 and will be reflected in the Nikkei 225's regular review scheduled for this autumn.
