Tang Weikun

This profile gathers the share dealings of Tang Weikun in Grand Pharmaceutical Group Ltd., where the filings describe the role as chief executive. Over a trading history stretching from 1 June 2021 to 27 August 2026, the count stands at 17 filings.

On the market, this insider has only ever bought: 16 purchases, €694k in total. Unlike grants, an open-market purchase is paid for by the insider, at the market price. In 2026 alone, the filings show 3 purchases and no sales.

Half of the purchases are above €45k and half below. Relative to company size, the median is 0.0019% of market cap (3 purchases with a known value). Of 16 purchases, 9 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The record was last updated on 27 August 2026 with an open-market purchase (€33k) in Grand Pharmaceutical Group Ltd. 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. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
