Jonathan H. Wolk

Jonathan H. Wolk is a declared insider at 2 companies (senior executive); the most frequent names are Mistras Group, Inc. and American Woodmark Corp. The record holds 71 filings, for trades running from 3 March 2006 to 3 January 2023.

Purchases make up the whole of the open-market record (12 purchases, €276k). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 57 share grants.

A typical purchase (the median) is worth €21k. Clusters matter here: 4 out of 5 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Ninety days after publication, 7 purchases show a median change of +5.8%, with the price up in 100% of them. Past outcomes like these are no guarantee of what comes next.

Most recently, on 3 January 2023, the filings show a share grant worth €22k in Mistras Group, Inc. The most recent open-market purchase was published on 5 June 2019, 2,713 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
