Filings by David L. Goodin span 2 companies, the busiest being MDU Resources Group Inc and NorthWestern Energy Group, Inc. Between 12 February 2009 and 1 October 2026, the trades on record add up to 69 filings.

The open-market side counts 11 purchases for €576k alongside 15 sales for €387k. Netting one side against the other leaves €189k of net buying. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 38 share grants and 2 option exercises.

The median purchase comes to €48k. On 2 out of 4 purchases, another insider of the same company was buying within the same 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. Looking at 11 purchases old enough to measure, the stock rose over the following 90 days in 91% of cases; the median change was +16.2%. They describe history only and say nothing certain about the share price ahead.

The newest entry dates from 5 October 2026: a share grant of €33k, in NorthWestern Energy Group, Inc. The most recent open-market purchase was published on 13 May 2020, 2,370 days ago. The median gap between a trade and its publication by SEC (Form 4) is 4 days. Section 16 rules allow two business days to file each Form 4. 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.
