James B. Weissman

Filings by James B. Weissman span 2 companies, the busiest being Dicerna Pharmaceuticals Inc and Telesis Bio Inc. Between 12 May 2016 and 24 July 2024, the trades on record add up to 68 filings.

Both buying and selling appear: 3 purchases worth €14k, against 30 sales worth €5.0M. On balance, insiders were net sellers of €5.0M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 4 share grants and 30 option exercises.

In size, the median ticket on the buying side is €1,533. No cluster: in 3 purchases, no other insider of the company bought within 30 days.

The record was last updated on 26 July 2024 with a share grant in Telesis Bio Inc. The latest purchase dates back some time: it was published 3,812 days ago, on 16 May 2016. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
