James M. Thorburn

James M. Thorburn (finance chief) discloses dealings in 2 companies, chiefly Twist Bioscience Corp and Ixys, LLC. We count 198 filings; the first trade dates from 3 August 2007 and the latest from 2 January 2024.

In open-market terms, that means 9 purchases worth €36k on one side and 83 sales worth €18.2M on the other. Taken together, the sales exceed the purchases by €18.1M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 59 share grants and 46 option exercises.

In size, the median ticket on the buying side is €3,081.

The latest filing, published on 4 January 2024, reports a share grant of €13k in Twist Bioscience Corp. The latest purchase dates back some time: it was published 6,316 days ago, on 24 July 2009. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. 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 SEC (Form 4). They describe what insiders did and are not a recommendation.
