United States Gasoline Fund 

This fund primarily allocates its capital to futures contracts linked to various grades of gasoline, crude oil, diesel-heating oil, natural gas, and other hydrocarbon-based energy products. Its primary performance benchmark is the gasoline futures contract listed on the New York Mercantile Exchange (NYMEX) that holds the nearest expiration date. A notable exception occurs when this closest-to-expire contract is less than two weeks from its expiration; in such cases, the benchmark transitions to the contract for the following month.
