| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? The Portfolio is designed to track the daily price movements of gold; thus the majority of its performance is linked to gold’s gains or losses. In the first half of 2024, gold’s gains were driven largely by global central bank buying, geopolitical and economic uncertainty, and continued strength of consumer demand. Adhering to its stated investment strategy, the Portfolio tracked closely with gold prices primarily by using futures contracts. However, rising short-term interest rates negatively impacted parts of the collateral portfolio used in the Portfolio. This is a known risk to the investment manager and performance fell within expectations for the period. The Portfolio will continue to execute its investment strategy in an effort to track daily gold prices. |
