All filings by Yang Jianxin on record concern CStone Pharmaceuticals - B. We count 124 filings; the first trade dates from 30 August 2022 and the latest from 3 November 2026.

On the open market, the record shows 76 purchases worth €5.1M and 15 sales worth €8.5M. The totals exclude 6 filings filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2026 alone, the filings show 13 purchases and 3 sales.

The median purchase comes to €45k. Measured against the company's value, the median purchase equals 0.0093% of market capitalisation, across 10 purchases where it is known. On 9 out of 71 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. After 67 purchases with a full 90-day history, the hit rate stands at 61% and the median 90-day move at +15.9%. Past outcomes like these are no guarantee of what comes next.

The newest entry dates from 5 November 2026: a transaction, in CStone Pharmaceuticals - B. The last purchase on record was published on 22 September 2026, which is 47 days ago. Between a trade and the moment it shows up on HKEX, the median delay is 2 days. The shorter that gap, the sooner other investors can see what insiders have done. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
