What Are Refining Stocks?

Refining stocks are shares of companies that process crude oil into petrol, diesel, aviation fuel and petrochemicals, and in some cases sell fuel through their own retail networks. Results depend on refining margins, crude oil prices, fuel demand and marketing margins, so the spread between product and crude prices decides profit.

Why Do Refining Stocks Have a Strong Roadmap in India?
