Sumitomo Densetsu Co.,Ltd. is a Construction company. Its directors and officers file their transactions with EDINET (Japan FSA). Over the twelve months to 18 October 2026, 6 filings were filed, from 3 insiders.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
Insider buying of Sumitomo Densetsu Co.,Ltd. has been absent for the past year. The median gap between a trade and its publication by EDINET (Japan FSA) is 7 days. The shorter that gap, the sooner other investors can see what insiders have done.
For context, the typical company on the same exchange (median of 3,419 companies) published 3 filings over the same period, against 6 filings here.
In the same sector, recent insider purchases at Lennar Corp /NEW/ also feature in our signals. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
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.
