Shenzhen Neptunus Bioengineering Co., Ltd.: what insiders have been doing
Shenzhen Neptunus Bioengineering Co., Ltd., founded in 1992, is a Health Care company based in Shenzhen, People's Republic of China. Its directors and officers file their transactions with SSE / SZSE (CSRC). 7 insiders have disclosed 16 filings since 6 November 2025.
The flow runs one way only: 7 insiders bought (16 purchases totalling €371k) and nobody sold on the market. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. At €77k, the purchase published on 23 July 2026 by 张锋 is the largest of the period. Those buying include 4 board members, 2 senior executives and 1 finance chief.
In all, 12 purchases were made within 30 days of a purchase by another insider of the company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The most recent open-market purchase was published on 21 September 2026, 48 days ago. 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.
Across the 522 companies tracked on its exchange, the median is 2 filings; at 16 filings, this issuer sits above that mark. Looking back to 2023, when coverage begins, insiders filed 16 purchases and 1 sale.
