Masahiko Kamata

Masahiko Kamata is a declared insider at 2 companies (major shareholder); the most frequent names are SBSホールディングス株式会社 and 鎌田正彦. Over a trading history stretching from 7 September 2021 to 16 October 2026, the count stands at 11 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The latest filing, published on 22 October 2026, reports a transaction in SBSホールディングス株式会社. The median gap between a trade and its publication by EDINET (Japan FSA) is 6 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.
