Share Buyback Information (EDINET) (/markets/share_buyback_edinet)

You can obtain data on share buyback status reports disclosed on EDINET

Overview

The dataset delivers detailed information on share buyback, disposal, and holding status of treasury shares for each day of the previous month, as reported in the filings submitted to EDINET.

This data is processed and distributed by JPX Market Innovation & Research, Inc. based on data obtained from the EDINET API.

Sources:

• EDINET Viewing (Submission) Site

• PDL1.0

Attention

• Data will not be provided for days when no share buyback status reports were submitted on EDINET.

• When multiple performance tables are included in the "1【取得状況】" section of the Share Buyback Report, a separate record is generated for each performance table.

  • In this case, multiple records with the same DocumentId and Code are returned.

  • For all fields other than the performance tables, the values will be identical across these records.
