CMK Corporation: what insiders have been doing
CMK Corporation belongs to the Chemicals sector. Filings by its managers are published through EDINET (Japan FSA). 3 insiders have disclosed 20 filings since 26 October 2025.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
No insider has bought CMK Corporation shares on the open market in the past twelve months. Typically, a trade is published a median of 7 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done.
With 20 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. Looking back to 2021, when coverage begins, insiders filed 55 purchases and 31 sales.
These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.

Transparent value + quality ranking, distinct from the insider signal.
