Mar. 09, 2023 TSE Optimization of Tick Sizes for Medium Liquidity Stocks (TOPIX Mid400)

Tokyo Stock Exchange, Inc. will optimize tick sizes for medium liquidity stocks in its regular trading session from June 5, 2023.
Specifically, tick sizes applied to TOPIX 100 constituents will also be applied to TOPIX Mid 400 constituents.
For medium liquidity stocks, execution costs associated with tick sizes remain high from a global perspective, and we have received requests for revisions from market users.
These revisions should allow various investors, particularly individual and long-term investors, to trade at better prices.
