Ryuhei Sadoshima

Ryuhei Sadoshima discloses dealings in 2 companies, chiefly セーフィー株式会社 and 佐渡島 隆平. Over a trading history stretching from 29 September 2021 to 21 October 2026, the count stands at 4 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The latest filing, published on 27 October 2026, reports a transaction in セーフィー株式会社. Typically, a trade is published a median of 6 days after it takes place. This delay matters because a trade only becomes useful information once it is public. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
