Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended May 31, 2025, the Fund returned 10.13%.The Fund underperformed the MSCI ACWI Index and the Morningstar Moderate Aggressive Target Risk Index, which returned 14.16% and 11.96%, respectively, for the same period. Adaptive Alpha Opportunities ETF (AGOX) remains largely diversified across countries and sectors. There are periods where AGOX uses its “Global-go-anywhere” classification to take advantage of a focused approach to a sector or group of sectors.During the one year period ended 5/31/2025, AGOX held modest allocations towards tech and semiconductor related positions. The VanEck Semiconductor ETF (SMH), Technology Select Sector SPDR ETF (XLK), and Invesco QQQ Trust (QQQ) all had drawdowns during the period that exceeded that of the benchmark resulting in a negative impact on relative performance. This impact was greatest during the semiconductor related sell offs in August 2024 and January 2025. US equity markets have generally trended positively over past year, which has benefitted the Fund's US growth-oriented portfolio. The main detractors from performance included: • Super Micro Computer Inc (SMCI) • Meta Platform Inc Class A (META) • Novo Nordisk AS ADR (NVO) The main contributors to performance included: • Howmet Aerospace Inc (HWM) • NVIDIA Corp (NVDA) • Carpenter Technology Corp (CRS) |

RH Tactical Rotation ETF (RHRX) maintained its half broad equities and half “tri-sector” approach utilizing research to choose in-favor sectors to hold at any given time.Although the sector concentration can enhance returns, focused sell-off scenarios (such as the sell off of the AI company DeepSeek in January 2025) can reduce alpha. RHRX also used Adaptive’s Growth or Value (GVI) model to determine when to allocate the broad equities portion of the portfolio between growth and value focus. Favorable market conditions for US large-cap growth companies had a positive impact on the segment of the Fund's portfolio allocated to these investments.
