Sato Kohei: trading record in brief
This profile gathers the share dealings of Sato Kohei in DYNAM JAPAN HOLDINGS Co., Ltd., where the filings describe the role as chief executive. We count 37 filings; the first trade dates from 30 May 2018 and the latest from 2 September 2026.
The open-market side counts 6 purchases for €16.8M alongside 27 sales for €30.3M. The amount is not disclosed for 7 filings. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. So far in 2026, the count stands at 3 purchases and 1 sale.
A typical purchase (the median) is worth €208k. Relative to company size, the median is 0.082% of market cap (3 purchases with a known value). Clusters matter here: 4 out of 5 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. After 4 purchases with a full 90-day history, the hit rate stands at 25% and the median 90-day move at -6.6%. Past outcomes like these are no guarantee of what comes next.
The latest filing, published on 4 September 2026, reports a transaction in DYNAM JAPAN HOLDINGS Co., Ltd. The latest purchase dates back some time: it was published 79 days ago, on 21 August 2026. Filings reach the HKEX feed a median of 2 days after the trade. This delay matters because a trade only becomes useful information once it is public. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from HKEX disclosures alone and does not predict where the share price will go.
