Investing in oil ETFs can be a complex endeavor. For most investors, even large traders, taking delivery of oil and storing it is simply impractical or impossible to do. Thus, oil ETFs have become a popular instrument with which to access the oil market. In today’s market, investors can find ETFs that track the daily price of oil and that aim to mitigate the effects of contango and backwardation, as well as ETFs exposed to companies in the oil sector.
