Overview
The Alerian Midstream Energy Index is a broad-based composite of North American energy infrastructure companies. The capped, float-adjusted, capitalization-weighted index, whose constituents earn the majority of their cash flow from midstream activities involving energy commodities, is disseminated real-time on a price-return (AMNA), total-return (AMNAX), net total-return (AMNAN), and adjusted net total-return (AMNTR) basis.
