XLE

XLE is an exchange-traded fund that bundles together the largest US energy companies, including major oil and gas producers, refiners, and pipeline operators like Exxon Mobil and Chevron. Rather than being a company itself, it is a basket of stocks that trades on the stock exchange, giving investors an easy way to bet on the energy sector as a whole instead of picking individual drillers or refiners. Its price moves up and down with the combined fortunes of the oil and gas industry, especially crude oil prices.
