No insider purchase over the last 90 days. The latest, by MCADAM WILLIAM J, was filed 20 Nov 2018.
Every trade that managers of SemGroup Corp disclose to SEC (Form 4) is tracked on this page. The past year has been quiet: not a single insider filing for SemGroup Corp. The previous disclosure was published on 6 December 2019.
The full history, which starts in 2016, counts 13 purchases against 7 sales.
This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.
