Quantitative Models and Construction Methods 1. Model Name: Convolutional Neural Network (CNN) for Price-Volume Data Modeling - **Model Construction Idea**: The model leverages convolutional neural networks to analyze standardized graphical representations of price-volume data, aiming to predict future price trends and map learned features to industry thematic indices[79][81] - **Model Construction Process**: - Standardize price-volume data into graphical formats for each stock within a specific time window[79] - Apply convolutional neural networks to extract features from these graphical representations[79] - Map the extracted features to thematic industry indices, such as the CSI Petrochemical Industry Index, CSI Subdivision Chemical Industry Theme Index, and others[81] - **Model Evaluation**: The model effectively identifies industry themes based on price-volume data and provides actionable insights for sector allocation[79][81] --- Model Backtesting Results 1. CNN Model - **Thematic Indices Configured**: - CSI Petrochemical Industry Index (h11057.CSI)[81] - CSI Subdivision Chemical Industry Theme Index (000813.CSI)[81] - CNI Oil & Gas Index (399439.SZ)[81] - CSI Oil & Gas Resources Index (931248.CSI)[81] - CNI Nonferrous Metals Index (399395.SZ)[81]

Group 1 - The underlying logic of the non-ferrous metals, liquor, and large refining sectors is interconnected, driven by the anticipated liquidity from the Federal Reserve's QE in 2026, which is expected to enhance the super cycle of commodities [1][10] - The current investment in the large refining sector is likened to the investment in non-ferrous metals last year, with expectations of a significant price increase in oil and chemical products by 2026, following the patterns observed in the non-ferrous sector [2][14] - The "anti-involution" trend in China is contributing to the upward momentum in the large refining sector, as capital expenditure is being restrained, leading to a significant slowdown in new capacity additions and a clearing of inventories, which supports future price elasticity [3][16] Group 2 - The large refining sector is still at a low valuation level, with significant room for valuation recovery compared to the non-ferrous sector, which has already experienced a systematic valuation increase [4][21] - Recent inflows from public funds, foreign investments, and ETFs into the large refining sector indicate a timely opportunity for investment, as the sector is positioned for a major upward trend [6][27] - The upcoming Federal Reserve QE in 2026 is expected to create a favorable environment for the large refining sector, alongside the anticipated recovery in consumer demand and high-end manufacturing sectors [7][37]

Investment Rating - The report maintains a "Buy" rating for key companies in the oil and gas sector, including China National Petroleum Corporation, China National Offshore Oil Corporation, China Petroleum & Chemical Corporation, Zhongman Petroleum, and New Natural Gas [2]. Core Insights - The report highlights that geopolitical tensions and cold weather have led to supply contraction expectations, driving oil prices up significantly. The U.S. oil production was impacted by a winter storm, resulting in a loss of up to 2 million barrels per day, approximately 15% of total U.S. production. Additionally, the report notes that geopolitical developments, particularly regarding Iran and the Middle East, will continue to influence short-term oil price fluctuations [8][11]. Summary by Sections 1. Weekly Insights - The oil and petrochemical sector saw a 6.9% increase, outperforming the CSI 300 index, which rose by 0.1% [16][19]. 2. Market Performance - The report indicates that the oil extraction sub-sector had the highest weekly increase of 12.3%, while the oil product sales and storage sub-sector had the smallest increase of 0.7% [19]. 3. Company Performance - Notable performers in the oil and petrochemical sector included PetroChina, which is recommended for its stable performance and high dividends, and CNOOC, which is highlighted for its low production costs and growth potential [14]. 4. Industry Dynamics - The report discusses OPEC+'s decision to maintain stable oil production levels amidst geopolitical risks and supply concerns. It also mentions the EU's approval to stop importing Russian natural gas by the end of 2027, which could impact global energy dynamics [24][25]. 5. Oil and Gas Prices - As of January 30, Brent crude oil futures settled at $70.69 per barrel, a 7.30% increase week-on-week, while WTI futures rose by 6.78% to $65.21 per barrel. The report also notes a decrease in U.S. oil production and refinery processing rates [12][13]. 6. Investment Recommendations - The report suggests three main investment lines: focusing on stable industry leaders like PetroChina and Sinopec, considering CNOOC for its strong earnings potential, and looking at growth companies like New Natural Gas and Zhongman Petroleum due to domestic encouragement for oil and gas production [14].
