Seiko Group Corporation: what insiders have been doing
This page follows insider dealings at Seiko Group Corporation as filed with EDINET (Japan FSA), a company from the Retail sector based in Ginza, Japan. The group dates from 1881. The last twelve months, up to 9 November 2026, brought 4 filings signed by 2 insiders.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
With 4 filings in twelve months, the company is more active than the median of 3 filings across the 3,233 companies we follow on the same exchange.
Over the last twelve months, not one insider purchase of Seiko Group Corporation stock was filed. The median gap between a trade and its publication by EDINET (Japan FSA) is 5 days. That lag is the time during which only the insider knows about the trade.
Elsewhere in the same sector, our signals recently picked up insider purchases at Harvia Oyj and Rusta AB (publ). 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.
Transparent value + quality ranking, distinct from the insider signal.
