Based on 3 purchases whose 90-day window has closed (published at least 91 days ago), the same population our ranking model reads.
Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
黄燕 (chief executive) discloses dealings in 沪硅产业 to SSE / SZSE (CSRC). The record holds 3 filings, for trades running from 19 July 2024 to 29 December 2025.
The open-market record is one-sided, with 3 purchases worth €12k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2025: 2 purchases and no sales on the market.
In size, the median ticket on the buying side is €4,925. Of 3 purchases, 3 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -8.8%. These figures describe past trades and do not predict future prices.
Most recently, on 29 December 2025, the filings show an open-market purchase worth €5,173 in 沪硅产业. The median gap between trade and publication is zero days: most filings appear on the same day. Until a filing is published, the market cannot know about the trade. Source: insider filings from SSE / SZSE (CSRC). Past trades are no guide to future returns.
