The Nifty Oil & Gas Index is a sectoral benchmark on NSE comprising India's major listed companies in the oil exploration, production, refining, distribution, and natural gas sectors — including integrated energy majors and downstream players. The index is closely tied to global crude oil prices, government pricing policy, and India's energy security initiatives. For traders and investors on Ventura Securities, the Nifty Oil & Gas Index is an essential reference for commodity-linked equity plays, tracking how crude price fluctuations, refining margins, and policy changes in fuel pricing impact stock valuations across the energy value chain.
