Aim of the Index

Japanese stock indices for mid and small cap equities are mostly based on indicators of liquidity, such as market capitalization and trading value, and it is not common to use capital efficiency and financial status as indicators for index constituent selection.
The new index applies the concept of the JPX-Nikkei Index 400, which is an index comprised of highly attractive listed companies, to mid and small cap equities by selecting companies that focus on capital efficiency and investor-oriented management, and aim to foster greater awareness of such issues among corporate executives. The index will also aim to meet the needs of investors looking to invest in such companies.
When selecting issues, we will also consider the liquidity of each issue in the market to facilitate the actual use of the new index for asset management.
