Headquartered in Aichi Prefecture, Japan, Taiho Kogyo Co.,Ltd. is a listed company and traces its origins to 1939. Filings by its managers are published through EDINET (Japan FSA). The last twelve months, up to 18 October 2026, brought 7 filings signed by 1 insider.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
With 7 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.
Over the last twelve months, not one insider purchase of Taiho Kogyo Co.,Ltd. stock was filed. Typically, a trade is published a median of 8 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done.
