    On June 1, 2006, Alerian launched the first real-time index to track MLP performance, the Alerian MLP Index (AMZ), which today remains the leading gauge of energy MLPs. The 50 constituents in the float-adjusted, capitalization-weighted index capture approximately 75% of total energy MLP market capitalization.

    Fun AMZ Facts:

    • In 2006, the 50 names in the AMZ had a combined market capitalization of $102 billion. Today, the combined market capitalization is $363 billion.
    • Of the 50 companies in the AMZ in June 2006, 23 of those names are index constituents today.
