George Bickerstaff

George Bickerstaff (board member) discloses dealings in 2 companies, chiefly CareDx, Inc. and Innoviva, Inc. The record holds 28 filings, for trades running from 1 January 2016 to 5 August 2026.

Both buying and selling appear: 1 purchase worth €106k, against 5 sales worth €3.1M. Sales outweigh purchases by €3.0M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 17 share grants and 5 option exercises. Since January 2026: no purchases and 1 sale on the market.

Most recently, on 6 August 2026, the filings show an open-market sale worth €803k in CareDx, Inc. The latest purchase dates back some time: it was published 1,972 days ago, on 25 May 2021. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. US insiders must file a Form 4 within two business days of a trade. 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 SEC (Form 4). They describe what insiders did and are not a recommendation.
