An analysis by The Motley Fool compares two major Master Limited Partnership (MLP) ETFs, Global X - MLP & Energy Infrastructure ETF (MLPX) and Alerian MLP ETF (AMLP), concluding that MLPX is the more practical and lucrative choice for most long-term investors. While AMLP offers a substantially higher trailing-12-month dividend yield of 7.3% compared to MLPX's 4.1%, its higher expense ratio of 1.01% (vs. MLPX's 0.45%) and C-corporation tax structure significantly erode total returns. MLPX, by contrast, avoids fund-level corporate taxes and has delivered more than double the returns of AMLP over the past decade, making it more tax-efficient and cost-effective.
