The ETRACS Alerian MLP Infrastructure ETN (MLPI) was the top performing exchange-traded product linked to the Alerian MLP Infrastructure Index (AMZI) for the month of October 2011, according to UBS INvestment Bank.
Both MLPI and the Alerian MLP ETF are designed to deliver the performance of the Alerian MLP Infrastructure Index
The Index is a liquid, midstream-focused subset of the Alerian MLP Index comprised of 25 energy infrastructure MLPs. The Index, whose constituents generally earn the majority of their cash flow from the transportation and storage of energy commodities provides investors with a benchmark for the infrastructure component of this emerging asset class. The Index is calculated using a capped, float-adjusted, capitalisation-weighted methodology that results in greater diversification versus a pure market capitalisation-weighted index.
