Hitchner III Kenneth Walton: trading record in brief
Hitchner III Kenneth Walton is a declared insider at 2 companies; the most frequent names are WuXi Biologics (Cayman) Inc. and CStone Pharmaceuticals - B. We count 25 filings; the first trade dates from 24 March 2021 and the latest from 8 June 2026.
The open-market side counts 14 purchases for €1.4M alongside 3 sales for €700k. The totals do not cover 2 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. 2026 to date brings 1 purchase and no sales.
The median purchase comes to €50k. Of 12 purchases, 7 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. After 12 purchases with a full 90-day history, the hit rate stands at 92% and the median 90-day move at +33.3%. Past outcomes like these are no guarantee of what comes next.
The newest entry dates from 10 June 2026: an open-market purchase of €198k, in CStone Pharmaceuticals - B. Filings reach the HKEX feed a median of 5 days after the trade. That lag is the time during which only the insider knows about the trade. Source: insider filings from HKEX. Past trades are no guide to future returns.
