Winston J. Churchill

Winston J. Churchill is a declared insider at 4 companies (board member); the most frequent names are Amkor Technology, Inc., Innovative Solutions & Support Inc and Societal CDMO, Inc. Between 4 January 2016 and 30 July 2026, the trades on record add up to 31 filings.

Both buying and selling appear: 3 purchases worth €86k, against 7 sales worth €566k. The amount is not disclosed for 1 filing. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 9 share grants and 10 option exercises. Since January 2026: no purchases and 1 sale on the market.

A typical purchase (the median) is worth €23k. 3 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The latest filing, published on 31 July 2026, reports a transaction in Amkor Technology, Inc. The last insider purchase was made public on 28 August 2023, 1,147 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each 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.
