Zuiko Corporation: what insiders have been doing
Zuiko Corporation, founded in 1963, is a Industrials company based in Ibaraki, Japan. Its directors and officers file their transactions with EDINET (Japan FSA). The last twelve months, up to 26 October 2026, brought 4 filings signed by 1 insider.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
Compared with its exchange (3,205 companies, median 3 filings), a count of 4 filings is above the norm. The full history, which starts in 2021, counts 28 purchases against no sales.
Insider buying of Zuiko Corporation has been absent for the past year. Typically, a trade is published a median of 11 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done.
This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
