WONG Chau Chi: trading record in brief
All filings by WONG Chau Chi on record concern Silkwave Inc, in the capacity of chief executive. We count 278 filings; the first trade dates from 5 July 2017 and the latest from 21 April 2026.
Both buying and selling appear: 156 purchases worth €17.6M, against 115 sales worth €20.8M. The amount is not disclosed for 143 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2026: no purchases and 1 sale on the market.
The median purchase comes to €15k. None of the 84 purchases we analysed coincided with buying by another insider of the same company within 30 days. Looking at 84 purchases old enough to measure, the stock rose over the following 90 days in 18% of cases; the median change was -11.2%. They describe history only and say nothing certain about the share price ahead.
Most recently, on 23 April 2026, the filings show an open-market sale worth €5.2M in Silkwave Inc. The most recent open-market purchase was published on 13 September 2025, 421 days ago. 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. Source: insider filings from HKEX. Past trades are no guide to future returns.
