| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? During the reporting period, the Fund generated a total return of 16.52% - at NAV. This compares to the 22.15% total return for the S&P 500® Index for the same period. Based on our key themes, we attempt to position the strategy with strong and consistent characteristic advantages versus the benchmark and relative to the overall market. Portfolio positions generally have higher revenue growth rates and higher margins. Though many of them trade at premium valuations to companies in the benchmark, we believe current valuations do not fully price in future cashflow (the net cash and cash equivalents transferred in and out of a company. Cash received represents inflows, while money spent represents outflows), generation potential meaning the stocks trade at an actual discount to the benchmark looking 4-6 years out. What Factors Influenced Performance In the current market environment of weakening economic growth and moderating inflation, we believe the Grizzle Growth ETF is best positioned utilizing a barbell portfolio approach of technology leaders and emerging disruptors. Tech leaders currently have a funding and competitive advantage and have been buying emerging leaders, cementing their grip on industry market share. We believe owning companies at both ends of the competitive spectrum dampens volatility while also offering upside through existing competitive advantages or through disruption of industry leaders. For the commodity pillar of the fund, we believe the structural demand opportunity for natural gas is significant, the near-term opportunity for North American gas to continue supplying demand growth worldwide is clear and in the medium to long-term we believe natural gas serves as an optimal transition fuel to lower emissions. The fund also seeks to own producers of the commodities fueling future technology trends with copper and lithium as two specific examples. We believe a decade of underinvestment in mining of certain commodities coupled with accelerating demand growth will lead to higher prices and better profitability over the medium term. |
