• The report tracks the prosperity signals of various industries, including coal, livestock farming, steel, structural materials, and fuel refining, based on recent industry operating indicators[9] - For the coal industry, the model uses price factors and capacity factors to estimate monthly revenue and profit growth rates[10] - The livestock farming model employs the "slaughter coefficient method" to calculate the supply-demand gap for pigs six months in advance, based on the relationship between piglet birth cycles and sow pregnancy arrangements. The formula is as follows: $ \text{Slaughter Coefficient} = \frac{\text{Quarterly Pig Slaughter}}{\text{Breeding Sow Inventory (Lag 6 months)}} $ $ \text{Potential Capacity (6 months later)} = \text{Breeding Sow Inventory (t)} \times \text{Slaughter Coefficient (t+6 months)} $[15][16] - For the steel industry, the model integrates comprehensive steel prices and cost indicators (e.g., iron ore, coke, pulverized coal, scrap steel) to predict monthly profit growth rates and calculate per-ton profitability[18] - The structural materials and construction engineering model tracks profitability changes in the glass and cement manufacturing industries using price and cost indicators. It also incorporates manufacturing PMI and real estate sales data to analyze potential investor expectations for infrastructure support[25] - The fuel refining and oil services model calculates industry profit growth rates and cracking spreads based on changes in fuel prices and crude oil prices. It also designs allocation signals using oil prices, cracking spreads, and new drilling activity[27] - Backtesting results for the coal industry show that profit growth signals do not indicate significant improvement, maintaining a neutral allocation view[14] - The slaughter coefficient method effectively identifies pig price upward cycles, with the Q2 2026 potential pig supply estimated at 167.73 million heads, slightly tight compared to the Q2 2025 demand of 171.43 million heads[16][17] - For the steel industry, December 2025 profit growth is predicted to be negative, with PMI rolling averages remaining unchanged, leading to a neutral allocation view[22] - The glass industry continues to show negative profit growth as of December 2025, while the cement industry also exhibits declining profits with no positive signals in new housing starts, maintaining a neutral view for both[26] - The fuel refining industry is predicted to have flat profit growth in December 2025, with oil prices continuing to decline and new drilling activity showing minimal change, resulting in a neutral allocation view for both refining and oil services[33][34]
