This page follows Sourcerock Group LLC’s institutional portfolio moves as disclosed in its Form 13F filings with the SEC, updated every quarter as new data becomes available. If you’re the kind of reader who tracks a portfolio manager’s new stock buys the way others follow Warren Buffett’s latest moves, this profile is built to give you a running record rather than a one-off snapshot.
Form 13F filings report holdings as of the end of a quarter, not the specific days trades happened, so all activity below is described as occurring during the quarter ending 2026-03-31 rather than on any exact date.
