Quantitative Models and Construction Methods 1. Model Name: Commodity Term Structure Simulation Portfolio - **Model Construction Idea**: This is a long-short strategy that dynamically holds long positions in commodities with high roll yields and short positions in commodities with low roll yields. The strategy aims to capture the term structure premium in commodity markets while reducing dependency on single market trends[33][35][34]. - **Model Construction Process**: 1. **Roll Yield Factor**: The roll yield is calculated to measure the contango or backwardation state of a commodity. 2. **Dynamic Positioning**: Commodities with high roll yields are dynamically allocated long positions, while those with low roll yields are allocated short positions. 3. **Portfolio Balancing**: The portfolio is rebalanced periodically to maintain the desired exposure to the roll yield factor[35][38]. - **Model Evaluation**: The strategy demonstrates flexibility in adapting to market risks and provides stable returns even in weak market trends[34]. 2. Model Name: Commodity Time-Series Momentum Simulation Portfolio - **Model Construction Idea**: This strategy captures medium- to long-term trends in commodity prices using multiple technical indicators. It dynamically allocates long positions to upward-trending assets and short positions to downward-trending assets[33][35]. - **Model Construction Process**: 1. **Trend Indicators**: Technical indicators such as moving averages and momentum are used to identify price trends. 2. **Dynamic Positioning**: Commodities with upward trends are allocated long positions, while those with downward trends are allocated short positions. 3. **Portfolio Rebalancing**: Positions are adjusted periodically based on updated trend signals[35][45]. - **Model Evaluation**: The strategy effectively tracks price trends but may underperform in volatile or trendless markets[45]. 3. Model Name: Commodity Cross-Sectional Inventory Simulation Portfolio - **Model Construction Idea**: This strategy uses inventory data to capture fundamental changes in commodity markets. Commodities with declining inventories are allocated long positions, while those with increasing inventories are allocated short positions[33][35]. - **Model Construction Process**: 1. **Inventory Factor**: Changes in inventory levels are calculated to assess supply-demand dynamics. 2. **Dynamic Positioning**: Commodities with declining inventories are dynamically allocated long positions, while those with increasing inventories are allocated short positions. 3. **Portfolio Rebalancing**: Positions are adjusted periodically based on updated inventory data[35][49]. - **Model Evaluation**: The strategy is effective in capturing fundamental supply-demand imbalances but may be sensitive to data accuracy and reporting delays[49]. --- Model Backtesting Results 1.

Factor Name: Roll Yield Factor - **Factor Construction Idea**: Measures the contango or backwardation state of a commodity to capture the term structure premium[35]. - **Factor Construction Process**: 1. Calculate the roll yield as the difference between the spot price and the futures price. 2. Normalize the roll yield across commodities to ensure comparability. 3. Rank commodities based on their roll yields and allocate positions accordingly[35]. 2. Factor Name: Trend Factor - **Factor Construction Idea**: Captures medium- to long-term price trends using technical indicators[35]. - **Factor Construction Process**: 1. Use moving averages, momentum, and other technical indicators to identify trends. 2. Normalize trend signals across commodities to ensure comparability. 3. Rank commodities based on their trend strength and allocate positions accordingly[35]. 3. Factor Name: Inventory Factor - **Factor Construction Idea**: Measures changes in inventory levels to capture supply-demand imbalances[35]. - **Factor Construction Process**: 1. Calculate the percentage change in inventory levels over a specified period. 2. Normalize inventory changes across commodities to ensure comparability. 3. Rank commodities based on their inventory changes and allocate positions accordingly[35]. --- Factor Backtesting Results 1.
