BrainAurora Medical Technology Ltd. - B: what insiders have been doing
BrainAurora Medical Technology Ltd. - B belongs to the Health Care sector. Filings by its managers are published through HKEX. In the past year (22 October 2025 to 22 October 2026), 27 filings came from 2 insiders.
Both sides are active: 15 purchases worth €58.2M and 7 sales worth €84.5M, from 1 insider and 2 insiders respectively. The totals do not cover 2 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. At €55.9M, the purchase published on 10 February 2026 by TAN Zheng is the largest of the period. Those buying include 1 senior executive.
Compared with its exchange (1,314 companies, median 4 filings), a count of 27 filings is above the norm. Over the whole record (from 2026), the tally stands at 15 purchases and 7 sales.
The most recent open-market purchase was published on 30 June 2026, 131 days ago. Between a trade and the moment it shows up on HKEX, the median delay is 3 days. That lag is the time during which only the insider knows about the trade.
