The fund is a leveraged ETF, and like all geared products, is intended to be held only for short periods. It is not appropriate for buy-and-hold investors. The fund provides up to 2x the return of a natural gas futures index on a daily basis. The index consists of two rolling natural gas future components weighted based on settlement and expiry signals. Daily compounding of returns can lead to the fund's returns varying significantly from the 2x exposure over a longer holding period. The fund is a tactical tool, so trading costs and volume matter.
