株式会社SUMCO: what insiders have been doing
株式会社SUMCO, founded in 1999, is a Banks company based in Shibaura, Japan. Its directors and officers file their transactions with EDINET (Japan FSA). Between 26 October 2025 and 26 October 2026, 7 insiders published 32 filings.
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.
Over the last twelve months, not one insider purchase of 株式会社SUMCO stock was filed. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 7 days. The shorter that gap, the sooner other investors can see what insiders have done.
With 32 filings in twelve months, the company is more active than the median of 3 filings across the 3,205 companies we follow on the same exchange. Since 2021, the database holds 12 purchases and 33 sales by insiders of the company.
This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
