Ronald J. De Lange

Ronald J. De Lange discloses dealings in 2 companies, chiefly Tekelec and Radisys Corp. The record holds 59 filings, for trades running from 15 August 2007 to 7 December 2017.

Both buying and selling appear: 10 purchases worth €31k, against 7 sales worth €1.1M. On balance, insiders were net sellers of €1.1M. 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 16 share grants and 25 option exercises.

A typical purchase (the median) is worth €2,041. 5 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

On 8 December 2017 came the latest disclosure, an option exercise in Radisys Corp. The most recent open-market purchase was published on 3 November 2016, 3,642 days ago. Typically, a trade is published a median of 1 day after it takes place. For comparison, the SEC allows two business days to file a 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.
