Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The RPAR Risk Parity ETF (“RPAR”) returned -0.11% (NAV) for the fiscal year ended December 31, 2024 as compared to 0.63% for the Advanced Research Risk Parity Index (the "RPAR Index"). RPAR seeks to achieve exposures similar to those of the RPAR Index. RPAR invests across four major asset classes: global equities, U.S. Treasuries, commodities and U.S. Treasury Inflation-Protected Securities ("TIPS"). These broad market segments were selected because each has historically outperformed during different economic environments.

What Factors Influenced Performance?

RPAR's 2024 performance resulted from a mix of strong and weak returns across its target asset allocations. Global equities (25% allocation) and gold (10%) delivered robust gains, driven by resilient U.S. economic growth and elevated geopolitical concerns, respectively. Gold's performance was further bolstered by strong central bank demand. However, long-term U.S. Treasuries (35%), long-term TIPS (35%), and commodity producer equities (15%) posted negative returns. Higher-than-expected economic growth pushed interest rates higher, reversing the easing that had been anticipated at the start of the year, which negatively impacted U.S. Treasuries and TIPS. Commodity prices suffered from weaker global demand, particularly from China. These divergent asset class performances ultimately led to a relatively flat year for RPAR.

Factors Affecting Performance [Text Block]

How did the Fund perform last year?

The UPAR Ultra Risk Parity ETF (“UPAR”) returned -2.78% (NAV) for the fiscal year ended December 31, 2024 as compared to -1.37% for the Advanced Research Ultra Risk Parity Index (the "UPAR Index"). UPAR seeks to replicate the returns of the UPAR Index. UPAR invests across four major asset classes: global equities, U.S. Treasuries, commodities and U.S. Treasury Inflation-Protected Securities ("TIPS"). These broad market segments were selected because each has historically outperformed during different economic environments.

What Factors Influenced Performance?

UPAR's 2024 performance resulted from a mix of strong and weak returns across its target asset allocations. Global equities (25% allocation) and gold (10%) delivered robust gains, driven by resilient U.S. economic growth and elevated geopolitical concerns, respectively. Gold's performance was further bolstered by strong central bank demand. However, long-term U.S. Treasuries (35%), long-term TIPS (35%), and commodity producer equities (15%) posted negative returns. Higher-than-expected economic growth pushed interest rates higher, reversing the easing that had been anticipated at the start of the year, which negatively impacted U.S. Treasuries and TIPS. Commodity prices suffered from weaker global demand, particularly from China. These divergent asset class performances ultimately led to a slightly negative year for UPAR.
