GFA Co., Ltd.

GFA Co., Ltd. has filed trades across 5 companies (mainly through EDINET (Japan FSA)), most often in ウインテスト株式会社, 株式会社イメージワン and 株式会社オウケイウェイヴ. We count 67 filings; the first trade dates from 30 January 2023 and the latest from 4 September 2025.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

Most recently, on 17 March 2026, the filings show a transaction in 株式会社イメージワン. Typically, a trade is published a median of 9 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
