| Factors Affecting Performance [Text Block] | How did the fund perform last year and what affected its performance? Portfolio performance summary For the annual period ending October 31, 2024, the Fund outperformed the Bloomberg Commodity Index Total Return (the "Benchmark") on a gross and net basis. Roll and curve-based commodity strategies contributed to relative performance while the management of the underlying cash also contributed to performance for the annual period, gross of fees. The Fund’s commodity exposure was generally positioned further out the curve than the Benchmark. What worked: - Curve positioning in Agriculture, Energy, Industrial and Precious metals sectors contributed to returns, gross of fees. What didn’t work: - Curve positioning in the Livestock sector detracted from Benchmark-relative performance. The Fund invested in derivatives such as futures and swap agreements (specifically, commodity index swaps) during the reporting period. | |
