Filings by Greg l. Armstrong span 3 companies, the busiest being NOV Inc., Plains ALL American Pipeline LP and Plains GP Holdings LP. Over a trading history stretching from 10 February 2016 to 11 August 2025, the count stands at 10 filings.

Both buying and selling appear: 3 purchases, against 1 sale worth €197k. No amount is published for 3 filings, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 4 share grants.

No cluster: in 3 purchases, no other insider of the company bought within 30 days.

The latest filing, published on 12 August 2025, reports a transaction in Plains GP Holdings LP. The last insider purchase was made public on 11 February 2016, 3,902 days ago. 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
