• The report tracks industry prosperity signals using quantitative models and indicators, focusing on coal, livestock, steel, structural materials, and fuel refining industries[9] - For the coal industry, the model uses price factors and capacity factors to estimate monthly revenue and profit growth rates. The formula is based on the monthly price index of thermal coal, which determines the sales price for the following month[10][14] - In the livestock industry, the "slaughter coefficient method" is applied to predict the supply-demand gap for pigs six months ahead. The formula is: $ \text{Slaughter Coefficient} = \frac{\text{Quarterly Pig Slaughter}}{\text{Breeding Sow Inventory (lagged 6 months)}} $ This method effectively identifies pig price upcycles based on historical data[15][16] - For the steel industry, the model incorporates comprehensive steel prices and cost indicators (e.g., iron ore, coke, coal, and scrap steel) to predict monthly profit growth and calculate per-ton profit[18][21] - In the structural materials sector, profitability changes in glass and cement manufacturing are tracked using price and cost indicators. These changes are used to design allocation signals. Additionally, manufacturing PMI and real estate sales data are analyzed to assess potential infrastructure investment expectations[24][26] - For the fuel refining and oil services industry, the model uses changes in fuel prices, crude oil prices, and cracking spreads to estimate profit growth and design allocation signals. The model also considers changes in new drilling activities[27][34][35]
