Mark M. Sieczkarek

Mark M. Sieczkarek discloses dealings in 3 companies, chiefly Conceptus Inc, Thermage Inc and Stablecoin Development Corp. The record holds 59 filings, for trades running from 12 December 2006 to 30 July 2019.

The open-market side counts 4 purchases for €308k alongside 30 sales for €4.3M. Sales outweigh purchases by €4.0M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 19 share grants and 4 option exercises.

The median purchase comes to €53k. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -5.4%. Past outcomes like these are no guarantee of what comes next.

On 6 August 2019 came the latest disclosure, a share grant in Stablecoin Development Corp. The most recent open-market purchase was published on 5 March 2015, 4,250 days ago. Typically, a trade is published a median of 4 days after it takes place. 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.
