NRGU is a leveraged exchange-traded note (ETN) that tracks the performance of the U.S. Big Oil Index, a market index composed of the largest oil and gas companies in the United States. This fund aims to provide investors with 3 times the daily return of the index, making it a high-risk, high-reward option for those looking to invest in the energy sector. However, due to its leveraged nature, NRGU is not suitable for all investors and should be carefully considered before investing.
