Michael E. Mikolajczyk

Michael E. Mikolajczyk (board member) discloses dealings in 3 companies, chiefly Rubicon Technology, Inc., Diamondcluster International Inc and Kanbay International Inc. In total, 69 filings cover trades dated from 15 September 2006 to 19 August 2022.

Both buying and selling appear: 8 purchases worth €242k, against 15 sales worth €2.1M. Sales outweigh purchases by €1.8M. 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 32 share grants and 5 option exercises. So far in 2022, the count stands at no purchases and 1 sale.

A typical purchase (the median) is worth €32k.

On 22 August 2022 came the latest disclosure, an open-market sale for €631k in Rubicon Technology, Inc. The last insider purchase was made public on 4 January 2016, 3,946 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
