Lis William David: trading record in brief

All filings by Lis William David on record concern Zai Lab Ltd. The record holds 3 filings, for trades running from 17 June 2026 to 12 August 2026.

Market trades split into 1 purchase and 2 sales (€38k). No amount is published for 1 filing, 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.

Most recently, on 14 August 2026, the filings show an open-market sale worth €23k in Zai Lab Ltd. The latest purchase dates back some time: it was published 117 days ago, on 23 June 2026. The median gap between a trade and its publication by HKEX is 3 days. The shorter that gap, the sooner other investors can see what insiders have done. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
