Energy

An energy pioneer

Alerian created the first real-time index for Master Limited Partnerships (MLPs) in 2006. The suite has evolved to include several widely used energy infrastructure benchmarks as well as other subsectors and themes within the broader energy universe.

Why energy infrastructure indexes?

Attractive yields

Energy infrastructure MLPs and corporations typically offer compelling yields above those provided by other income investments like bonds, utilities, and REITs.

Strong free cash flow generation

Most constituents generate free cash flow, returning it to shareholders through dividends and buybacks. Fee-based businesses drive stable and predictable cash flows.

Energy infrastructure

Exposure to long-lived real assets that generate inflation-protected cash flows.

Diversification

Energy infrastructure typically exhibits low correlations to other income-oriented investments such as utilities and bonds, while providing yields that are not dependent on interest rate levels. Broad market indexes do not include MLPs.

Index highlight

In 2006, Alerian Capital Management, then a dedicated MLP asset manager, launched the Alerian MLP Index (AMZ) to provide the first reliable benchmark for Master Limited Partnerships (MLPs). This led to the launch of the JP Morgan Alerian MLP Index ETN (AMJ) in 2009, the first passively-managed MLP exchange-traded product. Today, AMZ stands as the leading benchmark for energy infrastructure MLPs.

In 2010, Alerian spun off its asset management business to focus solely on energy infrastructure indexing and education. Later that year, ALPS launched the Alerian MLP ETF (AMLP), the first and largest MLP ETF, recognized for its liquidity and scale.

While VettaFi's Alerian index suite has evolved, our commitment to delivering transparent, reliable benchmarks and educating investors remains unwavering.
