Richard Parrillo (board member) discloses dealings in Hudson Technologies INC /ny to SEC (Form 4). The record holds 47 filings, for trades running from 8 May 2015 to 14 May 2026.

On the open market, the record shows 10 purchases worth €467k and 20 sales worth €1.3M. Sales outweigh purchases by €848k. 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 10 share grants and 7 option exercises. Since January 2026: 1 purchase and no sales on the market.

In size, the median ticket on the buying side is €16k. Clusters matter here: 8 out of 8 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

On 15 May 2026 came the latest disclosure, an open-market purchase for €15k in Hudson Technologies INC /ny. Typically, a trade is published a median of 1 day after it takes place. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
