许世业

许世业 is a declared insider of 建龙微纳, with filings sourced from SSE / SZSE (CSRC). Over a trading history stretching from 4 January 2022 to 29 December 2025, the count stands at 6 filings.

No open-market purchase appears, only 6 sales worth €110k. So far in 2025, the count stands at no purchases and 3 sales.

The newest entry dates from 29 December 2025: an open-market sale of €4,161, in 建龙微纳. The median gap between trade and publication is zero days: most filings appear on the same day. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
