The ETN is linked to an underlying index designed to mirror the price movements of an equally weighted portfolio that holds two distinct exchange-traded funds (ETFs). These ETFs, in turn, invest in preferred securities from various issuers. PFFL itself provides two times (2x) leveraged exposure to this index. This means the ETN will magnify any positive monthly compounded performance of the index by a factor of two, but it will also experience twice the impact of any negative monthly compounded performance.
