Not enough buy signals with a settled T+90 horizon to measure a track record yet.
Cathal G. Phelan (board member) discloses dealings in 3 companies, chiefly Impinj Inc, Virage Logic Corp and Cypress Semiconductor Corp /DE/. The record holds 83 filings, for trades running from 30 December 2005 to 20 May 2025.
Both buying and selling appear: 5 purchases worth €221k, against 42 sales worth €10.5M. On balance, insiders were net sellers of €10.3M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 6 share grants and 27 option exercises. So far in 2025, the count stands at no purchases and 3 sales.
Half of the purchases are above €50k and half below.
The newest entry dates from 21 May 2025: a share grant of €54k, in Impinj Inc. The most recent open-market purchase was published on 16 July 2021, 1,926 days ago. Filings reach the SEC (Form 4) feed a median of 3 days after the trade. 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
