Robert D. Short III

Robert D. Short III (senior executive) discloses dealings in VirnetX Holding Corp to SEC (Form 4). In total, 72 filings cover trades dated from 9 July 2011 to 7 July 2025.

Both buying and selling appear: 6 purchases worth €93k, against 22 sales worth €5.5M. Sales outweigh purchases by €5.4M. 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 22 share grants and 18 option exercises.

The median purchase comes to €11k. For 6 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 83% of cases, with a median move of +38.7%. Past outcomes like these are no guarantee of what comes next.

On 11 July 2025 came the latest disclosure, a share grant for €526 in VirnetX Holding Corp. The most recent open-market purchase was published on 30 November 2015, 3,981 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
