MLPX vs TMLP

MLPXBGlobal X MLP & Energy Infrastructure ETF

TMLPCTortoise MLP ETF

In short

MLPX A focused bet on the toll roads of American energy: roughly 30 pipeline and infrastructure names tracking the Solactive MLP & Energy Infrastructure Index, running since 2013 at 0.45% a year.

TMLP MLP exposure without the K-1 envelope. TMLP takes its index exposure through total return swaps inside a RIC structure, so shareholders get a single Form 1099 and skip the fund-level deferred tax accrual that C-corp MLP funds carry.

Stated mandate

MLPX The fund seeks to provide investment results that generally correspond, before fees and expenses, to the price and yield performance of the Solactive MLP & Energy Infrastructure Index.

TMLP The Fund seeks to track, before fees and expenses, the total-return performance of the Tortoise MLP Index SM.

Why people hold it

• MLPX 0.45% a year, against a peer-group median near 0.79% for energy sector ETFs. Cheap shelf space for a narrow corner of the market.
• Concentrated on purpose: around 30 pipeline and energy infrastructure names via the Solactive MLP & Energy Infrastructure Index, so the midstream theme isn't watered down.
• Trading since 2013 and now a multi-billion-dollar fund with steady volume, which tends to keep spreads manageable on retail-size orders.
• Distributions land on a quarterly schedule, so the payout rhythm is predictable even as the amounts move with the underlying cash flows.

• TMLP Full MLP index exposure via total return swaps in a RIC wrapper: one Form 1099, no K-1s, and none of the fund-level deferred tax liability legacy C-corp MLP funds accrue.tortoisecapital.com
• Tracks the Tortoise MLP Index, a rules-based benchmark with a 10-plus year history covering 20-some partnerships across energy transport, processing and storage.tortoisecapital.com
• Home-field advantage: Tortoise launched the first MLP closed-end fund in 2004 and built this index itself rather than licensing someone else's.tortoisecapital.com
• Pays quarterly, with distributions designed to line up with the cash-generating profile of the index's underlying MLPs.tortoisecapital.com

Worth knowing

• MLPX One sector, one theme. Energy infrastructure rides commodity cycles and rate moves, so it can travel well out of step with a broad market fund.
• With around 30 holdings, individual pipeline operators carry real weight and one company's news can move the whole fund.
• Not the cheapest ticket in the cohort: XES charges 0.35%, though it buys oil services companies rather than midstream infrastructure.

• TMLP 0.50% a year sits a bit above the typical index-tracking ETF. That's the toll for the swap-based, K-1-free plumbing.
• Swaps carry counterparty risk. The fund may deal with one or a limited number of counterparties, and a counterparty default would reduce the value of your shares.tortoisecapital.com
• A December 2025 launch: still small and thinly traded, and non-diversified, so spreads can be wider and a short list of names drives the ride.tortoisecapital.com
