AOMAiShares Core 40/60 Moderate Allocation ETF

DDXCDefined Duration 10 ETF

In short

AOM Wall Street's balanced portfolio in one ticker, tilted toward bonds: 40% stocks, 60% fixed income, held through a handful of iShares funds and tracking an S&P target-risk index since 2008.

DDX Most balanced funds set their stock/bond mix by your risk tolerance. DDX sets it by your calendar: a 10-year target duration, with the mix swinging countercyclically between 70/30 and 30/70 stocks and bonds.

Stated mandate

AOM The Fund seeks to track an index composed of underlying equity and fixed income funds intended to represent a moderate target-risk allocation strategy.

DDX The Fund seeks long-term growth of capital through a globally diversified portfolio of broad-based stock and bond ETFs. Its portfolio is systematically reallocated to reduce relative stock and bond risks and investment volatility.

Why people hold it

AOM Fee is 0.15%, net of a waiver through November 30, 2026, and below the typical cost in its small category. Gross runs 0.20% if that waiver lapses.
Undercuts moderate-allocation rivals AVMA (0.21%) and CGBL (0.33%), neither of which leans on a waiver.
One ticker buys a global stock-and-bond mix and holds it at target. The index handles the rebalancing, so you are not trimming sleeves by hand.
Trading since 2008 and now a multi-billion-dollar fund that has hugged its index closely. One of the stronger builds in a thin peer group.

DDX Allocation driven by time horizon rather than a risk questionnaire: a 10-year defined duration target, rebalanced countercyclically within a 70/30 to 30/70 stock-bond band.disciplinefunds.com etfarchitect.com
One ticket holds broad-based stock and bond ETFs: a globally diversified equity sleeve plus a bond sleeve limited to high-quality US government debt at shorter average maturities.disciplinefunds.com
Live since 2021 as the original Discipline Fund ETF, managed by firm founder Cullen Roche, and now the middle rung of a 5-, 10- and 20-year Defined Duration lineup.disciplinefunds.com disciplinefunds.com 2

Worth knowing

AOM Bonds are the bigger half, so stock swings land with less force here than in equity-heavier sibling AOR (also 0.15% net of a waiver through November 30, 2026).
Moderately traded rather than heavily traded, which can mean wider spreads around the open and close.
You own funds that own funds: the line items are iShares ETFs, not individual stocks and bonds.

DDX 0.25% net of a waiver through November 30, 2026 (0.29% gross) sits near the category median, while index-built AOR and AOM charge 0.15% net of waivers through November 30, 2026.
By design the fund can spend long stretches underweight stocks, so its path can look nothing like a static 60/40 for years at a time.disciplinefunds.com
Small and thinly traded next to the giant allocation ETFs, which tends to mean wider bid-ask spreads at the point of trade.
