Not one of the filings records a straightforward purchase or sale on the market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 24 March 2026 came the latest disclosure, a transaction in 株式会社マナック・ケミカル・パートナーズ. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 39 days. Until a filing is published, the market cannot know about the trade. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
