Every open-market trade on record is a purchase: 15 purchases worth €5.3M, and no sale. The amount is not disclosed for 2 filings. Unlike grants, an open-market purchase is paid for by the insider, at the market price. 2025 to date brings 4 purchases and no sales.

Half of the purchases are above €308k and half below. Of 13 purchases, 7 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. For 13 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 23% of cases, with a median move of -15.1%. These figures describe past trades and do not predict future prices.

The record was last updated on 10 December 2025 with an open-market purchase in Jinxin Fertility Group Ltd. The median gap between a trade and its publication by HKEX is 1 day. The shorter that gap, the sooner other investors can see what insiders have done. Source: insider filings from HKEX. Past trades are no guide to future returns.
