Companies that operate within the oil and gas industry are plentiful, with activities including drilling, extraction, oilfield services, oil refining, and transportation. Oil is a vital energy product in a vast number of industries around the world. While oil alternatives begin to make headway within the energy market, demand for oil remains high. The oil industry provides investors with an opportunity to participate in a growth-oriented equity market that boasts exponential profit margins for the long term.
Despite the individual and commercial demand for oil products on a global scale, the oil industry comes with a great deal of risk to investors. Investing in the oil industry can be done through the purchase of industry-focused mutual fund shares. While there are a number of mutual funds that have substantial holdings in the oil sector, the majority of funds fall under natural resources or energy categories.
Key Takeaways
- The energy sector can attract investors who are looking to diversify their portfolio, to speculate on the demand for oil and fossil fuels, or see it as a hedge against inflation.
- Oil and energy mutual funds are tasked with investing exclusively in that sector by investing a majority of their portfolios in companies related to energy.
- There are several energy funds out there, and here we just look at a few of them. Energy ETFs also exist that may be a more accessible option for individual investors.
