A typical purchase (the median) is worth €28k. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 0% of cases; the median change was -13.7%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 15 August 2018, the filings show an option exercise in NPK International Inc. The clock since the last published purchase (8 December 2008) now reads 6,544 days. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
