JPX Market Innovation & Research, Inc. (JPXI), a provider of Japanese financial market data, announced today the launch of two new datasets for J-Quants Pro: the Listed Shares Flash Data and the Listed Shares Corporate Action Factors Dataset.

J-Quants Pro delivers insightful market data to corporate users through API, SFTP, and Snowflake.

Traditionally, Tokyo Stock Exchange (TSE) has published the number of listed shares around the 20th of each month, along with factors influencing changes such as capital increases, stock splits, and the exercise of subscription warrants. However, investors and market participants have sought more timely information.

The newly introduced Listed Shares Flash Data and Listed Shares Corporate Action Factors provide the latest figures on a daily basis, eliminating the need to wait for the monthly publication that provides the reasons behind day to day changes. This enables users to monitor changes in listed shares more efficiently and respond swiftly to market developments.

Listed Shares Flash Data

Provides the daily number of listed shares for all TSE listed companies, reflecting corporate actions such as capital increases, stock splits, and warrant exercises.

Three types of share counts are included:

• Shares issued
• Shares listed
• Shares used for index calculation

Although these values ultimately align, the timing of changes may differ depending on the type of corporate action.

Listed Shares Corporate Action Factors

Provides the day to day differences in the number of shares and the reasons behind such changes for all TSE listed companies.
