ProShares Ultra Bloomberg Natural Gas (BOIL) Diversifiers

ETF · Currency in USD · Last updated Jun 4, 2026

BOIL is an exchange-traded fund (ETF) managed by ProShares, a provider of ETFs that focus on alternative and leveraged investment strategies. The fund seeks daily investment results that correspond to two times (2x) the daily performance of the Bloomberg Natural Gas Subindex, a benchmark for natural gas futures.

The main feature of BOIL is its 2x leveraged exposure to natural gas futures, achieved primarily through financial instruments such as futures contracts and swap agreements. As a result, BOIL is designed for investors looking for a high-risk, high-reward investment strategy and willing to accept significant volatility in their portfolio. Because returns compound daily, BOIL is intended for short-term tactical trading rather than a buy-and-hold strategy, and performance over periods longer than a single day can diverge significantly from 2x the underlying index's return.

BOIL was launched on October 4, 2011, and is issued by ProShares. Investors should carefully review the fund's current prospectus for the most up-to-date expense ratio and risk information before investing.
