Common questions
What do oil & gas refining and marketing companies do?
They buy crude oil or other raw fuel, process it into products such as gasoline and diesel, or distribute and sell fuel to customers. Some companies focus on refining, some on selling fuel, and some do both.
What do Marvin's scores mean in this list?
Overall, quality and opportunity scores run on a scale from zero to one hundred and compare a company with others in the same industry today. They are not predictions, and they say nothing about how a stock will perform.
Why do most of these companies show falling revenue?
Among the companies with growth data, all but Star Group and Clean Energy Fuels reported lower revenue in their last fiscal year. In this industry, sales often move with fuel prices, so revenue can fall when prices fall even if the business is otherwise steady. Check margins and debt alongside growth.
