Zhou Weichang

This profile gathers the share dealings of Zhou Weichang in WuXi Biologics (Cayman) Inc. In total, 64 filings cover trades dated from 10 January 2018 to 2 June 2025.

The open-market side counts 7 purchases alongside 21 sales for €52.0M. The amount is not disclosed for 7 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2025: no purchases and 6 sales on the market.

The newest entry dates from 5 June 2025: an open-market sale of €5.9M, in WuXi Biologics (Cayman) Inc. The last purchase on record was published on 2 April 2024, which is 932 days ago. Typically, a trade is published a median of 4 days after it takes place. 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. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
