| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Commodity Index Total Return (the Index): ↑ The Fund’s exposure to cocoa helped Index-relative returns amid adverse weather conditions in the Ivory Coast and Ghana that sent commodity prices soaring during the period ↑ The Fund’s exposure to Robusta coffee contributed to Index-relative performance, as poor weather conditions in key growing regions generated crop shortages ↑ Contract selections in natural gas contributed to Fund performance relative to the Index ― primarily the result of a significant drop in natural gas spot prices during the first quarter of 2024 ↓ The Fund’s underweight exposure to gold detracted from Index-relative returns, as the U.S. Federal Reserve’s easing monetary policy helped lift gold prices ↓ An underweight exposure to crude oil hurt Index-relative returns, as oil prices increased due, in part, to escalating geopolitical tensions in the Middle East ↓ The Fund’s exposure to palladium hampered Index-relative returns, partially due to the market’s expectation of a 2025 inventory surplus of the precious metal |
