Ryo Kubota

All filings by Ryo Kubota on record concern 窪田製薬ホールディングス株式会社. We count 10 filings; the first trade dates from 27 September 2019 and the latest from 22 December 2025.

Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 23 December 2025, reports a transaction in 窪田製薬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 1 day. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
