Sankyo Seiko Co.,Ltd.: what insiders have been doing
Sankyo Seiko Co.,Ltd. belongs to the Banks sector. Filings by its managers are published through EDINET (Japan FSA). In the past year (26 October 2025 to 26 October 2026), 1 filing came from 1 insider.
Not one of the filings records a straightforward purchase or sale on the market. 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.
With 1 filing in twelve months, the company is quieter than the median of 3 filings across the 3,205 companies we follow on the same exchange. Over the whole record (from 2022), the tally stands at 5 purchases and 8 sales.
There has been no open-market purchase by an insider of Sankyo Seiko Co.,Ltd. for at least a year.
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.
