H. Grahame Heather: trading record in brief
H. Grahame Heather (board member) discloses dealings in Northwestern Corp to SEC (Form 4). We count 42 filings; the first trade dates from 2 August 2010 and the latest from 13 December 2022.
On the open market, the record shows 11 purchases worth €355k and 10 sales worth €2.1M. The net balance comes to €1.8M on the selling side. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 21 share grants.
Half of the purchases are above €13k and half below. For 11 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 64% of cases, with a median move of +1.8%. These figures describe past trades and do not predict future prices.
The latest filing, published on 15 December 2022, reports a share grant in Northwestern Corp. The last insider purchase was made public on 11 December 2014, 4,351 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
