Steven M. Klein

Steven M. Klein (chief executive) discloses dealings in 3 companies, chiefly Northfield Bancorp, Inc., Middlesex Water Co and Columbia Financial, Inc./MD/. Between 5 August 2021 and 20 July 2026, the trades on record add up to 28 filings.

Both buying and selling appear: 3 purchases worth €565k, against 2 sales worth €36k. The net balance comes to €530k on the buying side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 18 share grants and 2 option exercises. Since January 2026: 1 purchase and no sales on the market.

In size, the median ticket on the buying side is €78k. 2 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

On 22 July 2026 came the latest disclosure, an open-market purchase for €437k in Columbia Financial, Inc./MD/. 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. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
