Masao Matsumoto

Masao Matsumoto is a declared insider at 2 companies (major shareholder); the most frequent names are 株式会社藤商事 and 株式会社 藤商事. Over a trading history stretching from 28 February 2023 to 2 October 2026, the count stands at 40 filings.

No open-market purchase appears, only 36 sales. No amount is published for 36 filings, which the totals therefore leave out. 2026 to date brings no purchases and 36 sales.

On 7 October 2026 came the latest disclosure, a transaction in 株式会社藤商事. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 30 days. Until a filing is published, the market cannot know about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
