Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance Subadvisor: Quantix Commodities LP Performance Summary The Fund returned 6.90% for the year ended October 31, 2024. The Fund seeks to track the performance of the Quantix Commodity Index (the “Index”), which returned 7.44% during the same period. Top contributors to performance included: • The Precious Metals sector, which was the biggest positive contributor due to Gold, which is the largest individual commodity weight in the Index. • The Industrial Metals sector, with gains coming from Copper as Chinese stimulus package hopes supported demand expectations. Top detractors from performance included: • The Petroleum sector, particularly Heating Oil, Gasoil and Gasoline, detracted due to relatively subdued demand during peak driving season, along with an unexpectedly calm hurricane season. • The Grains sector, notably Corn and Soybeans, detracted likely due to healthy global stocks-to-use ratios (a measure of supply and demand) and favorable weather patterns in the key producing regions. |

Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance Subadvisor: Quantix Commodities LP Performance Summary The Fund returned -7.07% for the year ended October 31, 2024. The Fund seeks to track the performance of the Quantix Energy Transition Index, which returned -4.96% during the same period. Top contributors to performance included: • Silver, which benefitted from a combination of the performance of Gold (arising from Central Bank diversification) as well as industrial demand in what is potentially a deficit market. Top detractors from performance included: • European Natural Gas (TTF) returns, which were negatively impacted by roll yield, a practice of moving from an expiring futures contract to one further out the curve to maintain exposure to the commodity. |
