Masahide Sekine

Filings by Masahide Sekine span 2 companies, the busiest being 株式会社シイエヌエス and 関根 政英. Over a trading history stretching from 20 August 2021 to 4 November 2025, the count stands at 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.

The record was last updated on 4 November 2025 with a transaction in 株式会社シイエヌエス. Typically, a trade is published a median of 5 days after it takes place. Until a filing is published, the market cannot know about the trade. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
