The Defined Duration 10 ETF, trading under the ticker DDX, operates as an actively managed exchange-traded fund designed to achieve a balanced blend of capital growth and preservation for investors. This multi-asset fund strategically allocates between 30% and 70% in high-quality U.S. bonds and 30% to 70% in global equities, primarily through a diversified portfolio of other ETFs and U.S. Treasury Bills. Its core objective is to align with intermediate-term financial planning needs, specifically targeting a 10-year investment horizon. The ETF employs a distinctive, rules-based methodology, featuring systematic and time-weighted rebalancing that adjusts holdings countercyclically. This approach aims to minimize volatility arising from fluctuations in both equity and bond markets. Managed by Discipline Funds, DDX serves as a tool for individuals and financial advisors looking to match assets with defined future liabilities or planning milestones. The fund transitioned its name from Discipline Fund ETF (DSCF) to Defined Duration 10 ETF and its ticker to DDX on November 5, 2025, alongside a reduction in its investment advisory fees. Investors gain exposure to a diversified portfolio while paying an annual expense ratio, which was recently reduced to 0.25%.
