Colin Walsh: trading record in brief
Colin Walsh appears in our data through filings on Attovia Therapeutics, Inc. shares, published by SEC (Form 4). In total, 54 filings cover trades dated from 5 August 2026 to 6 August 2026.
On the open market, the record shows 4 purchases worth €17.8M and 46 sales worth €3.9M. Purchases outweigh sales by €13.9M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.
A typical purchase (the median) is worth €4.5M.
The newest entry dates from 28 August 2026: an open-market sale of €1.4M, in Attovia Therapeutics, Inc. The latest purchase dates back some time: it was published 50 days ago, on 28 August 2026. Typically, a trade is published a median of 15 days after it takes place. 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. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
