Robert B. Fagenson: trading record in brief
Filings by Robert B. Fagenson span 5 companies, the busiest being DSS, Inc., National Holdings Corp and Quantum Computing Inc. Between 14 September 2006 and 13 April 2026, the trades on record add up to 55 filings.
The open-market side counts 27 purchases for €299k alongside 5 sales for €1.3M. On balance, insiders were net sellers of €1.0M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 6 share grants and 6 option exercises.
The median purchase comes to €3,863. Clusters matter here: 2 out of 6 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. For 16 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 100% of cases, with a median move of +10.6%. Past outcomes like these are no guarantee of what comes next.
The newest entry dates from 14 April 2026: a share grant of €127k, in Quantum Computing Inc. The most recent open-market purchase was published on 5 December 2016, 3,625 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. 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.
