Zai Lab Ltd. Stock: price and insider trades · Hong Kong

Zai Lab Ltd. belongs to the Health Care sector. Filings by its managers are published through HKEX. In the past year (18 October 2025 to 18 October 2026), 38 filings came from 9 insiders.

Open-market activity splits into 12 purchases totalling €7,340 and 13 sales totalling €29.1M; 9 insiders sit on the buying side and 2 insiders on the selling side. No amount is published for 11 filings, which the totals therefore leave out. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. At €20.0M, the sale published on 21 May 2026 by Du Ying is the largest of the period (0.80% of market cap). The buyers include 9 senior executives.

For context, the typical company on the same exchange (median of 750 companies) published 5 filings over the same period, against 38 filings here. Since 2026, the database holds 12 purchases and 13 sales by insiders of the company.

The most recent open-market purchase was published on 3 July 2026, 107 days ago. Typically, a trade is published a median of 5 days after it takes place. That lag is the time during which only the insider knows about the trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

Other companies in the same sector with recent insider buying flagged by our signals: Cooper Companies, Inc. and Anixa Biosciences Inc. This summary is built from HKEX disclosures alone and does not predict where the share price will go.
