David John Mastrocola: trading record in brief
This profile gathers the share dealings of David John Mastrocola in Cooper-Standard Holdings Inc. We count 8 filings; the first trade dates from 9 May 2013 and the latest from 13 March 2026.
The open-market record is one-sided, with 6 purchases worth €344k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 2 option exercises. 2026 to date brings 3 purchases and no sales.
A typical purchase (the median) is worth €52k. Of 6 purchases, 1 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. After 6 purchases with a full 90-day history, the hit rate stands at 50% and the median 90-day move at +1.6%. These figures describe past trades and do not predict future prices.
Most recently, on 13 March 2026, the filings show an open-market purchase worth €39k in Cooper-Standard Holdings Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
