AMLP vs MLPI: Own the MLP Index, or Sell Some Upside?

The result: MLPI targets nearly double AMLP's distribution rate, but carries significantly higher complexity and nascent fund history.

How they differ

The core distinction is strategy. AMLP is a plain-vanilla index tracker—it holds the constituents of the Alerian MLP Infrastructure Index and distributes the underlying yield plus modest capital appreciation. MLPI uses an overlay strategy, typically involving covered calls or similar options techniques, to amplify income beyond what the MLP holdings alone would generate. That difference shows in the numbers: MLPI's 14.06% distribution rate nearly doubles AMLP's 7.39%, though MLPI's 0.68% expense ratio is lower than AMLP's 1.01%.

The second major difference is fund maturity and stability. AMLP launched 08/25/2010 and manages $13.5B in assets, having weathered multiple energy cycles. MLPI is brand new, having launched 12/18/2025, with only $46.4M in AUM. That newness matters: the options strategy hasn't been stress-tested through a full market cycle, and the fund's small size leaves open questions about scalability and whether current income can be sustained.

Third is distribution frequency. AMLP pays Quarterly, matching typical MLP patterns. MLPI pays Monthly, compounding income timing and reinvestment decisions for monthly-income seekers.

Who each is best for

AMLP: Fits investors who want straightforward MLP exposure with a reliable 7%+ yield, can tolerate energy sector volatility, and prefer a mature, large-cap fund with a transparent index methodology and 16 years-year track record.

MLPI: Designed for investors who prioritize maximum monthly income, accept the risks of options-based strategies and early-stage fund management, and have the analytical capacity to monitor how the overlay's performance holds up as the fund matures and market conditions shift.

Key risks to know

• NAV erosion at extremely high distribution yield. A 14.06% annual yield on a -range equity price implies distributions will likely exceed underlying total return in most years, particularly in lower energy-price environments. Over time, that math pressures NAV downward unless the options overlay generates returns well above normal equity appreciation.

• Options overlay sustainability risk. Covered-call and other income-generating overlays work best in choppy, range-bound markets; they cap upside and can lag in strong rallies. In a sustained bull market or during sharp downturns, the overlay's income contribution may shrink or the strategy may underperform a simple long position. MLPI is too new to show how this trade-off plays out across a full cycle.

• Fund scale and liquidity. MLPI's $46.4M in assets is very small for an ETF strategy requiring active hedging and rebalancing. Meaningful inflows could force difficult scaling decisions; outflows risk making the fund uneconomical to operate, which would threaten its closure.

• MLP sector and structure risk. Both funds carry inherent MLP risks: these are high-leverage entities sensitive to energy prices, interest rates, and equity market sentiment. They also distribute taxable income, including return-of-capital treatment that defers but doesn't eliminate tax liability. Energy prices and midstream utilization are cyclical.

• Limited track record on income stability. AMLP's 16 years-year history shows what MLP income looks like across cycles; MLPI has 8 months of data. The sustainability and volatility of MLPI's elevated payout are untested.

Bottom line

If you want proven MLP exposure with a stable, well-capitalized fund and can accept a 7%+ yield, AMLP offers simplicity and a long operational track record. If you're chasing 14.06% income and are comfortable with options-strategy complexity and the execution risk of a brand-new fund, MLPI's higher payout may appeal—but you're accepting an unproven strategy in a very small fund. The elevated yield difference demands scrutiny of how sustainable it truly is. Past performance of the Alerian index doesn't predict how MLPI's overlay will perform going forward.
