Apr. 28, 2023 JPXI Removal of Phased Weighting Reduction from Tokyo Stock Exchange Mothers Index and Change of Name of Index

 

In April 2021, JPX Market Innovation and Research, Inc. (JPXI) decided through the Index Consultation that Tokyo Stock Exchange Mothers Index would continue to be calculated after reviewing the calculation guidelines in response to the market restructuring on April 4, 2022.

From the viewpoint of index continuity, issues which are to be removed from the index as a result of the periodic review carried out in October 2022 were to be designated as “phased weighting reduction constituents”. The weighting of phased weighting reduction constituents was to be reduced in three stages on the last business day of every quarter from the last business day of October 2022, and these constituents were to be removed from the index on the last business day of April 2023.

Today, JPXI announced that phased weighting reduction constituents have been removed from Tokyo Stock Exchange Mothers Index. The component stocks of the index as of April 28, 2023 are as follows.
