Defined Duration 20 ETF

Cboe: DDXX

Listed November 13, 2025

Overview

DDXX is a Defined Duration ETF targeting a 20-year time horizon across its holdings using a systematic and time-weighted 100% equity allocation. DDXX is designed to generate capital growth over long periods to align with financial planning needs over multi-decade periods.

Portfolio Construction

DDXX is designed to keep investors aligned with a consistent 20-year investment horizon. Using the Defined Duration framework, the Fund builds a rules-based portfolio of 100% global equities. We start by assessing the defined duration of the three major regions of the global equity market (U.S., foreign developed, and emerging markets) and apply style tilts as needed to achieve the target defined duration of 20 years.

For example, when the global equity composite exceeds the 20-year horizon, DDXX might apply value and quality tilts that empirically shorten equity duration, bringing the portfolio back toward its target. The process systematically measures the expected real-return horizon of different regions and styles, then blends them to maintain the target while broadening diversification across global markets. Its allocation is as follows:

1. Fund of funds: Allocates across highly liquid, broadly diversified ETFs/funds for exposure to thousands of underlying instruments.
2. 100% global stocks: Maintains exposure to a core position of global equities across the three major regions including U.S., foreign developed, and emerging markets.
3. Style tilts: Tilts to different styles including value, small, momentum, quality, etc., as needed to maintain the target defined duration of ~20 years.
