Vincent J. Arnone

Vincent J. Arnone (chief executive) discloses dealings in Fuel Tech, Inc. to SEC (Form 4). The record holds 41 filings, for trades running from 27 March 2006 to 6 March 2026.

In open-market terms, that means 14 purchases worth €224k on one side and 8 sales worth €2.0M on the other. Sales outweigh purchases by €1.8M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 18 share grants and 1 option exercise. In 2026 alone, the filings show 1 purchase and no sales.

The median purchase comes to €17k. Clusters matter here: 5 out of 14 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. After 14 purchases with a full 90-day history, the hit rate stands at 50% and the median 90-day move at +0.1%. They describe history only and say nothing certain about the share price ahead.

The latest filing, published on 9 March 2026, reports an open-market purchase of €11k in Fuel Tech, Inc. 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. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
