Beijing Haitian Ruisheng Science Technology Ltd.: what insiders have been doing
Beijing Haitian Ruisheng Science Technology Ltd. is a Technology company. Its directors and officers file their transactions with SSE / SZSE (CSRC). In the past year (4 November 2025 to 4 November 2026), 2 filings came from 2 insiders.
The flow runs one way only: 2 sales worth €306k, from 2 insiders, and no purchase. One trade stands out by size: a sale of €191k from 黄宇凯, disclosed on 12 May 2026.
Compared with its exchange (516 companies, median 2 filings), a count of 2 filings is typical. Looking back to 2024, when coverage begins, insiders filed no purchases and 17 sales.
Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Other companies in the same sector with recent insider buying flagged by our signals: Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by SSE / SZSE (CSRC). They describe what insiders did and are not a recommendation.
