Keizo Sekiya

This profile gathers the share dealings of Keizo Sekiya across 2 companies, led by 株式会社ディスコ and 関家 圭三. Between 17 September 2021 and 16 April 2025, the trades on record add up to 4 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

Most recently, on 24 April 2025, the filings show a transaction in 株式会社ディスコ. Typically, a trade is published a median of 3 days after it takes place. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
