東亜建設工業(株) is a Construction company. Its directors and officers file their transactions with EDINET (Japan FSA). Over the twelve months to 18 October 2026, 3 filings were filed, from 1 insider.
The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
For context, the typical company on the same exchange (median of 3,425 companies) published 3 filings over the same period, against 3 filings here.
No insider has bought 東亜建設工業(株) shares on the open market in the past twelve months. Filings reach the EDINET (Japan FSA) feed a median of 8 days after the trade. Until a filing is published, the market cannot know about the trade.
For comparison within the same sector, see the insider buying recorded at Lennar Corp /NEW/. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.
