Group 1: Coal Industry - In June 2025, coal prices are lower than the same period last year, leading to a forecast of a year-on-year decline in industry profits for July 2025, maintaining a neutral outlook for the coal industry [3]. Group 2: Livestock Farming - As of the end of May 2025, the number of breeding sows is 40.42 million, showing a slight month-on-month increase. It is predicted that the supply and demand for pigs will balance in Q4 2025, with pork prices expected to stabilize at the bottom while waiting for a significant reduction in production capacity [4]. Group 3: Steel Industry - A forecast for June 2025 indicates a year-on-year negative growth in profits for the general steel industry. The rolling average of PMI has not exceeded the threshold, maintaining a neutral signal for the steel industry [5]. Group 4: Construction Materials and Engineering - In June 2025, the gross profit of float glass is expected to decline year-on-year, maintaining a neutral signal for the glass industry. The cement industry is predicted to see year-on-year profit growth in June 2025, awaiting positive signals from new housing starts, also maintaining a neutral outlook for the cement industry [5]. - The manufacturing PMI rolling average is stabilizing, while year-on-year data for commercial housing sales shows a slight decline. Economic data remains stable, and expectations for infrastructure support are unlikely to materialize, maintaining a neutral signal for the construction and decoration industry [5]. Group 5: Fuel Refining and Oil Services - A forecast for June 2025 suggests that profits in the fuel refining industry will remain roughly flat year-on-year, maintaining a neutral outlook. Oil prices have not yet formed an upward trend year-on-year, and new drilling activities are also stable year-on-year, leading to a neutral outlook for oil services [6].

Quantitative Models and Construction Methods 1. Model Name: Coal Industry Profit Forecast Model - **Model Construction Idea**: The model estimates monthly revenue and profit growth rates for the coal industry based on changes in price and capacity factors[10] - **Model Construction Process**: - The pricing mechanism is determined by the last price index of the previous month, which sets the sales price for the next month[10] - The model incorporates price factors and capacity factors to estimate revenue and profit growth rates on a monthly basis[10] - **Model Evaluation**: The model provides a systematic approach to track and predict industry profitability trends, but no significant improvement signals were observed for July 2025[13] 2. Model Name: Hog Supply-Demand Gap Estimation Model - **Model Construction Idea**: The model leverages the stable proportional relationship between hog slaughter and sow inventory lagged by six months to estimate future supply-demand gaps[14] - **Model Construction Process**: - The slaughter coefficient is calculated as: $ \text{Slaughter Coefficient} = \text{Quarterly Hog Slaughter} / \text{Sow Inventory (Lagged 6 Months)} $[14] - Future potential supply is estimated as: $ \text{6-Month Potential Supply} = \text{Current Sow Inventory} \times \text{Slaughter Coefficient (6 Months Ago)} $[15] - Future demand is projected based on historical quarterly slaughter data[15] - **Model Evaluation**: Historical data shows that this method effectively identifies hog price upward cycles[15] 3. Model Name: Steel Industry Profit Forecast Model - **Model Construction Idea**: The model predicts monthly profit growth rates and calculates per-ton profit for the steel industry by considering steel prices and raw material costs[17] - **Model Construction Process**: - The model integrates steel prices with the costs of raw materials such as iron ore, coke, pulverized coal, and scrap steel to estimate profit growth rates[17] - **Model Evaluation**: The model highlights the industry's profit trends but indicates a negative profit growth rate for June 2025[21] 4. Model Name: Glass and Cement Industry Profitability Tracking Model - **Model Construction Idea**: The model tracks profitability changes in the glass and cement industries using price and cost indicators, and designs allocation signals based on these changes[23] - **Model Construction Process**: - For the glass industry, the model calculates gross profit based on price and cost data[27] - For the cement industry, the model incorporates coal fuel price changes to predict profit growth rates[27] - **Model Evaluation**: The model effectively tracks profitability trends but maintains a neutral signal for both industries due to the lack of significant positive indicators[27] 5. Model Name: Refining and Oilfield Services Profitability Model - **Model Construction Idea**: The model estimates profit growth rates and cracking spreads for the refining industry based on changes in fuel prices, crude oil prices, and new drilling activity[28] - **Model Construction Process**: - The model uses variations in fuel and crude oil prices to calculate profit growth rates and cracking spreads[28] - Allocation signals are designed based on observed changes in oil prices, cracking spreads, and new drilling activity[28] - **Model Evaluation**: The model predicts stable profit growth for June 2025 but maintains a neutral signal due to the lack of significant upward trends in oil prices and drilling activity[35][38] --- Backtesting Results of Models 1. Coal Industry Profit Forecast Model - **Excess Return**: The model tracks the historical excess return of the coal industry relative to the Wind All-A Index, showing a declining profit trend for July 2025[13] 2. Hog Supply-Demand Gap Estimation Model - **Supply-Demand Balance**: The model predicts a balanced supply-demand scenario for Q4 2025, with potential supply at 18,226 million heads and demand at 18,244 million heads[16] 3. Steel Industry Profit Forecast Model - **Profit Growth**: The model forecasts a negative profit growth rate for June 2025, with no significant improvement in PMI rolling averages[21] 4. Glass and Cement Industry Profitability Tracking Model - **Glass Industry**: Gross profit for float glass continues to decline year-on-year as of June 2025[27] - **Cement Industry**: Profit growth is predicted to be positive for June 2025, driven by lower coal fuel prices[27] 5. Refining and Oilfield Services Profitability Model - **Profit Growth**: The model predicts stable profit growth for the refining industry in June 2025, with oil prices and new drilling activity showing no significant upward trends[35][38]

Quantitative Models and Construction 1. Model Name: Coal Industry Profit Forecast Model - **Model Construction Idea**: The model estimates the revenue and profit growth rate of the coal industry based on changes in price and capacity factors[10] - **Model Construction Process**: - The pricing mechanism is determined by the long-term contract system, where the sales price for the next month is based on the last price index of the current month[10] - The model uses the year-on-year changes in price and capacity factors to estimate monthly revenue and profit growth rates[10] - **Model Evaluation**: The model provides a systematic approach to track and predict industry profitability, but it relies heavily on the stability of the pricing mechanism and external factors like market demand[10][14] 2. Model Name: Hog Supply-Demand Gap Estimation Model - **Model Construction Idea**: The model predicts the hog supply-demand gap six months ahead based on the breeding sow inventory and historical slaughter coefficients[15] - **Model Construction Process**: - The slaughter coefficient is calculated as: $ \text{Slaughter Coefficient} = \frac{\text{Quarterly Hog Slaughter}}{\text{Breeding Sow Inventory (Lagged 6 Months)}} $[15] - The potential supply six months later is estimated as: $ \text{Potential Supply (t+6)} = \text{Breeding Sow Inventory (t)} \times \text{Slaughter Coefficient (t+6, YoY)} $[15] - The potential demand six months later is estimated as: $ \text{Potential Demand (t+6)} = \text{Hog Slaughter (t+6, YoY)} $[16] - **Model Evaluation**: Historical data shows that this model effectively identifies hog price upward cycles, making it a valuable tool for supply-demand analysis[16] 3.
