| Factors Affecting Performance [Text Block] | How did the Fund perform? The Kingsbarn Dividend Opportunity ETF (the “Fund”) returned 22.49% for the period of November 2, 2023 to October 31, 2024. The Fund underperformed its broad-based benchmark, the S&P 500® Index, which returned 36.58% for the same period. The Fund outperformed its secondary indices, the MVIS US Mortgage REITs Index and the MVIS US Business Development Companies Index, which returned 18.50% and 18.43% during the same period, respectively. What Factors Influenced Performance? The period of November 2, 2023, to October 31, 2024, was a challenging one in which to manage a yield-oriented portfolio, as market rates remained volatile, and the treasury yield curve stayed inverted throughout the year. The Fund outperformed its benchmarks, the MVIS US Mortgage REITs Index and the MVIS US Business Development Companies Index, during this period. This overperformance was due to the Fund’s larger allocation to commercial mortgage REITs, reflecting the thesis that multifamily assets would not incur the losses assumed by the marketplace, as reflected in equity valuations. Market Outlook In our view, economic growth is moderating from an above-trend growth rate to trend growth. However, we don’t think the deceleration is significant or happening fast enough to provide the Federal Reserve with the comfort it needs to cut rates commensurate with market expectations. We continue to think the market’s anticipation of substantial Fed easing may be overly optimistic. As the Fed continues to monitor economic and inflationary conditions, we think it is more probable that their approach to rate cuts will remain measured and incremental. | |
