Ryoyo Electro Corporation

This profile gathers the share dealings of Ryoyo Electro Corporation across 3 companies, led by リョーサン菱洋ホールディングス株式会社, 株式会社リョーサン and HPCシステムズ株式会社. Over a trading history stretching from 14 February 2023 to 14 November 2025, the count stands at 6 filings.

Not one of the filings records a straightforward purchase or sale on the market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

Most recently, on 21 November 2025, the filings show a transaction in HPCシステムズ株式会社. Filings reach the EDINET (Japan FSA) feed a median of 7 days after the trade. That lag is the time during which only the insider knows about the trade. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
