Every trade that managers of Showa Manufacturing Co.,Ltd. disclose to EDINET (Japan FSA) is tracked on this page. From 18 October 2025 to 18 October 2026, the disclosure feed for Showa Manufacturing Co.,Ltd. logged 4 filings by 2 insiders.
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.
With 4 filings in twelve months, the company is more active than the median of 3 filings across the 3,419 companies we follow on the same exchange.
No insider has bought Showa Manufacturing Co.,Ltd. shares on the open market in the past twelve months. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 7 days. This delay matters because a trade only becomes useful information once it is public.
