Toho Acetylene Co.,Ltd.: what insiders have been doing
This page follows insider dealings at Toho Acetylene Co.,Ltd. as filed with EDINET (Japan FSA), a company from the Chemicals sector based in Miyagi Prefecture, Japan. The group dates from 1955. The last twelve months, up to 26 October 2026, brought 48 filings signed by 2 insiders.
The flow runs one way only: 1 insider bought (42 purchases) and nobody sold on the market. The totals exclude 42 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The buyers include 1 major shareholder.
The last purchase on record was published on 29 September 2026, which is 41 days ago. Filings reach the EDINET (Japan FSA) feed a median of 36 days after the trade. That lag is the time during which only the insider knows about the trade.
With 48 filings in twelve months, the company is more active than the median of 3 filings across the 3,205 companies we follow on the same exchange. The full history, which starts in 2021, counts 42 purchases against no sales.
