SEIYU KOGYO Co.,Ltd.: what insiders have been doing
SEIYU KOGYO Co.,Ltd. is a listed company. Its insiders report their share dealings to EDINET (Japan FSA). The last twelve months, up to 22 October 2026, brought 1 filing signed by 1 insider.
Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
Across the 3,384 companies tracked on its exchange, the median is 3 filings; at 1 filing, this issuer sits below that mark. Since 2023, the database holds 2 purchases and 3 sales by insiders of the company.
There has been no open-market purchase by an insider of SEIYU KOGYO Co.,Ltd. for at least a year.
Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
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.
