Industries' Descriptions

@Oil Refining/Marketing (+1.36% weekly)

The Oil Refining/Marketing segment includes companies that refine crude oil into a number of petroleum products, including gasoline, jet fuel and diesel, and then sell the usable products to the end users. These companies are involved in what’s called downstream operations in the oil business. They also engage in the marketing and distribution of crude oil and natural gas products. In other words, the downstream oil and gas business is focused on post-production processes of crude oil and natural gas. When oil prices slump, downstream businesses are hurt less or in some cases even benefit, since their purchase cost of crude oil goes down. Some of the biggest U.S. oil refining/marketing companies include Phillips 66, Marathon Petroleum Corporation and Valero Energy Corp.
