Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Elm Market Navigator ETF delivered performance of 9.29% (NAV) since inception through September 30, 2025 and a six-month return of 11.42%. Performance from January 1, 2025 through September 30, 2025 was 12.28% (NAV), which includes performance of the legacy portfolio prior to the commencement of the ETF on February 10, 2025.
The first half of 2025 showcased Dynamic Index Investing’s responsiveness. ELM entered the year with reduced equity exposure, which proved fortuitous ahead of Liberation Day and the sharp global equity selloffs driven by trade and inflation concerns. Following the market turbulence, ELM’s rules-based approach increased equity exposure as markets stabilized and reversed, with allocations rising substantially through Q2. In stark contrast, Q3 demonstrated the strategy’s discipline during calm markets—virtually no material changes occurred to US equity, non-US equity, or fixed income weights throughout the quarter, avoiding unnecessary trading when conditions remained stable. This combination of responsiveness when needed and stability when appropriate illustrates how Dynamic Index Investing navigates varying market environments.
