Energy and utilities: insider trades when the price is set elsewhere
Two very different businesses
This sector mixes oil and gas producers, whose profits follow crude and gas prices, with utilities and renewable developers, whose returns depend on regulated tariffs, long-term power contracts and interest rates. In both cases much of what moves the shares is public: commodity quotes, regulatory decisions, auction results.
What insiders can know first
Management's edge lies in company news: reserve revisions, drilling outcomes, project delays, asset sales, a dividend decision. World commodity prices are not part of that edge. We found no peer-reviewed study that measures the informativeness of insider trades at energy companies as a group, so the sector is read through the general evidence: purchases carry more information than sales, and the effect is concentrated in smaller firms (Lakonishok and Lee, 2001, Review of Financial Studies).
Practical caveats
Small exploration companies, where a single well or permit can move the share price, sit closer to the small firm samples in which insider purchases carried the most information. Large integrated groups and utilities are followed by many analysts, which narrows any edge. A filing records one person's disclosed trade and says nothing about where the oil price will go.
