Grand Pharmaceutical Group Ltd.: what insiders have been doing
Grand Pharmaceutical Group Ltd. is a Health Care company. Its directors and officers file their transactions with HKEX. From 22 October 2025 to 22 October 2026, the disclosure feed for Grand Pharmaceutical Group Ltd. logged 6 filings by 2 insiders.
Only purchases show up on the open market, 6 purchases in all worth €210k, filed by 2 insiders. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. One trade stands out by size: a purchase of €46k from Tang Weikun, disclosed on 18 November 2025. Among those who bought: 2 senior executives.
In all, 3 purchases were made within 30 days of a purchase by another insider of the company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last insider purchase was made public on 7 September 2026, 62 days ago. Publication is fast: at least half of the trades appear on HKEX on the same day. This delay matters because a trade only becomes useful information once it is public.
For context, the typical company on the same exchange (median of 1,314 companies) published 4 filings over the same period, against 6 filings here. The full history, which starts in 2018, counts 31 purchases against 3 sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at UCB. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
