Every trade that managers of Showa System Engineering Corporation disclose to EDINET (Japan FSA) is tracked on this page. Between 18 October 2025 and 18 October 2026, 2 insiders published 4 filings.
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.
For context, the typical company on the same exchange (median of 3,419 companies) published 3 filings over the same period, against 4 filings here.
Over the last twelve months, not one insider purchase of Showa System Engineering Corporation stock was filed. Typically, a trade is published a median of 7 days after it takes place. Until a filing is published, the market cannot know about the trade.
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.
Transparent value + quality ranking, distinct from the insider signal.
