LME lead inventory has been destocked, and the long - signal strength on the inventory side has increased. The spread between the near and far months of LME lead has narrowed, the long feedback on the spread side has weakened, and the signal has changed from long to neutral. [13] - **Float Glass**: The operating rate of float glass enterprises has decreased slightly month - on - month, and the supply side has turned long. The transaction volume of commercial housing in first - and second - tier cities has increased, and the demand side is long. Float glass enterprises in Shandong and Guangdong have slightly destocked, and the inventory side continues to be long. The daily after - tax gross profit of float glass made from pipeline gas continues to be in a loss, and the profit side continues to be short. [15]

Report Summary 1. Report Information - Report Title: Commodity Quantitative CTA Weekly Tracking [1] - Author: Guotou Futures Research Institute, Financial Engineering Group - Date: December 30, 2025 - Focus: Colored Metals Sector Cross-Sectional Momentum Reversal [2] 2. Core View - The proportion of long and short positions in commodities has changed little this week. The factor intensity of the colored metals and precious metals sectors has slightly declined, while that of the agricultural products sector has slightly increased. Currently, the cross-sectionally stronger sectors are colored metals and black metals, and the weaker one is agricultural products [3]. - In terms of strategy net worth, different factors have different trends in different periods, and the comprehensive signals vary among different commodities [5][10][13][15]. 3. Key Points by Category 3.1 Commodity Sector Analysis - **Colored Metals**: The short - term momentum of the colored metals sector continues to rise, with a certain reversal in the term structure. Copper and alumina are weak in the cross - section. The time - series momentum of gold rises slightly, and the silver position shows a marginal decline [3]. - **Black Metals**: The time - series momentum of the black metals sector shows a marginal recovery, the cross - sectional differentiation narrows, and the positions of coking coal and coke remain high [3]. - **Energy and Chemicals**: The short - cycle momentum factor of the energy and chemicals sector recovers, and soda ash is in the cross - sectionally short end [3]. - **Agricultural Products**: The cross - sectional differentiation of oilseeds and meals narrows, the overall time - series momentum recovers, but the position does not change significantly [3]. 3.2 Factor Performance and Strategy Net Worth - **Factor Performance Table 1**: | Factor | Last Week's Return (%) | Current Month's Return (%) | | --- | --- | --- | | Supply | 0.02 | 0.02 | | Demand | - 0.03 | - 0.31 | | Inventory | 0.05 | 0.51 | | Spread | 0.00 | 0.00 | | Aggregate of Major Categories | 0.04 | 0.05 | [4] - **Strategy Net Worth 1**: Last week, the supply factor strengthened by 0.02%, the demand factor weakened by 0.03%, the inventory factor increased by 0.05%, and the synthetic factor increased by 0.04%.
