Martin A. Dietrich

Martin A. Dietrich, listed as board member, appears in our data through filings on NBT Bancorp Inc shares, published by SEC (Form 4). Over a trading history stretching from 20 January 2006 to 19 May 2026, the count stands at 178 filings.

Both buying and selling appear: 4 purchases worth €33k, against 34 sales worth €9.6M. Netting one side against the other leaves €9.6M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 102 share grants and 26 option exercises.

In size, the median ticket on the buying side is €7,236. Looking at 4 purchases old enough to measure, the stock rose over the following 90 days in 100% of cases; the median change was +9.8%. They describe history only and say nothing certain about the share price ahead.

The latest filing, published on 21 May 2026, reports a share grant in NBT Bancorp Inc. The most recent open-market purchase was published on 30 July 2007, 7,041 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
