Paul J. Isaac: trading record in brief

This profile gathers the share dealings of Paul J. Isaac across 3 companies, led by Stereotaxis, Inc., American Community Properties Trust and Sonida Senior Living, Inc. Between 28 September 2009 and 17 November 2025, the trades on record add up to 80 filings.

In open-market terms, that means 54 purchases worth €1.9M on one side and 25 sales worth €13.6M on the other. On balance, insiders were net sellers of €11.7M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 1 share grant. So far in 2025, the count stands at 5 purchases and no sales.

The median purchase comes to €14k. The 49 purchases reviewed show no overlap with other insiders buying the same stock within a month. After 49 purchases with a full 90-day history, the hit rate stands at 59% and the median 90-day move at +18.7%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 18 November 2025, reports an open-market purchase of €19k in Stereotaxis, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
