Denka Company Limited

This profile gathers the share dealings of Denka Company Limited across 2 companies, led by 高圧ガス工業株式会社 and 日本カーバイド工業株式会社. Between 13 December 2023 and 10 March 2026, the trades on record add up to 4 filings.

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.

On 11 March 2026 came the latest disclosure, a transaction in 高圧ガス工業株式会社. Publication is fast: at least half of the trades appear on EDINET (Japan FSA) on the same day. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
