Filings by Jiang Frank Ningjun span 2 companies, the busiest being CStone Pharmaceuticals - B and Jiangsu Hengrui Pharmaceuticals Co., Ltd. In total, 13 filings cover trades dated from 26 February 2019 to 25 March 2026.

Both buying and selling appear: 3 purchases, against 5 sales worth €13.5M. No amount is published for 6 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2026 alone, the filings show no purchases and 1 sale.

On 2 April 2026 came the latest disclosure, an open-market sale in Jiangsu Hengrui Pharmaceuticals Co., Ltd. The most recent open-market purchase was published on 19 August 2019, 2,638 days ago. The median gap between a trade and its publication by HKEX is 5 days. This delay matters because a trade only becomes useful information once it is public. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from HKEX disclosures alone and does not predict where the share price will go.
