Chau On Ta Yuen

Chau On Ta Yuen is a declared insider at 3 companies; the most frequent names are Come Sure Group (Holdings) Ltd., ELL Environmental Holdings Ltd. and Million Hope Industries Holdings Ltd. We count 6 filings; the first trade dates from 6 January 2020 and the latest from 9 October 2025.

On the open market, the record shows 2 purchases and 4 sales worth €3.2M. The amount is not disclosed for 5 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2025 to date brings no purchases and 1 sale.

The newest entry dates from 17 October 2025: an open-market sale, in Million Hope Industries Holdings Ltd. The latest purchase dates back some time: it was published 1,080 days ago, on 6 November 2023. The median gap between a trade and its publication by HKEX is 7 days. This delay matters because a trade only becomes useful information once it is public. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
