Koike Yasuhito

Koike Yasuhito appears in our data through filings on IZUMIグループ株式会社 shares, published by EDINET (Japan FSA). We count 4 filings; the first trade dates from 31 March 2026 and the latest from 9 April 2026.

Not one of the filings records a straightforward purchase or sale on the market. 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.

On 17 April 2026 came the latest disclosure, a transaction in IZUMIグループ株式会社. The median gap between a trade and its publication by EDINET (Japan FSA) is 8 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
