Alerian MLP Equal Weight Index

The Alerian MLP Equal Weight Index is the equal-weighted version of the widely used Alerian MLP Index (AMZ). The index, which includes the same companies as the float-adjusted, capitalization-weighted AMZ but allocates the same weight to each constituent at each rebalancing, is disseminated real-time on a price-return basis (AMZE) and on a total-return basis (AMZEX).
