Sotirios J. Vahaviolos

Sotirios J. Vahaviolos is a declared insider of Mistras Group, Inc. (chief executive), with filings sourced from SEC (Form 4). In total, 57 filings cover trades dated from 8 October 2009 to 6 March 2024.

Both buying and selling appear: 4 purchases worth €551k, against 13 sales worth €28.0M. Netting one side against the other leaves €27.4M of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 33 share grants and 2 option exercises.

A typical purchase (the median) is worth €96k. Looking at 4 purchases old enough to measure, the stock rose over the following 90 days in 75% of cases; the median change was +8.7%. These figures describe past trades and do not predict future prices.

The latest filing, published on 19 August 2024, reports a transaction in Mistras Group, Inc. The latest purchase dates back some time: it was published 2,412 days ago, on 1 April 2020. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
