Valero Energy Corporation (VLO) Stock Analysis & Winston Score

Valero Energy is one of the largest oil refiners in the world. It takes crude oil and turns it into everyday products like gasoline, diesel, and jet fuel. These products are sold to gas stations, trucking companies, airlines, and other businesses that need fuel to operate. Valero makes money by buying crude oil, refining it, and selling the finished products at a higher price. The difference between those two prices is called the "crack spread," and it is the main driver of Valero's profits. The company operates around 15 refineries across the United States, Canada, and the United Kingdom, giving it a large and geographically spread-out production base. Its sheer size and refining capacity make it hard for smaller competitors to match its efficiency. The biggest risk Valero faces is that refining margins can shrink quickly when crude oil prices rise or fuel demand falls, making profits unpredictable from year to year.
