Quantitative Models and Construction Methods 1. Model Name: Size Rotation Model Based on Odds and Win Rates - **Model Construction Idea**: The model integrates the concepts of odds and win rates to capture the rotation between large-cap and small-cap stocks. Odds are derived from valuation differences, while win rates are calculated using multiple indicators[4][30][40] - **Model Construction Process**: - **Odds Calculation**: - Define odds as the ratio of average positive returns to the absolute value of average negative returns - Formula: $ \mathbb{R}_{\mathbb{B}}^{\pm}\,\mathbb{R}=-\frac{\sum_{i=1}^{n}r e t u r n_{i}\,/n}{\sum_{j=1}^{m}r e t u r n_{j}\,/m} $ where $ \mathbb{R}_{\mathbb{B}}^{+} $ represents positive returns and $ \mathbb{R}_{\mathbb{B}}^{-} $ represents negative returns[30][31] - Use historical valuation differences between large-cap (CSI 300) and small-cap (CSI 2000) indices to estimate odds through linear regression[32][36] - **Win Rate Calculation**: - Combine multiple indicators (e.g., Shibor, short-term credit spread, market trend, market volatility, style momentum, style crowding, and calendar effects) to derive a composite win rate signal - Assign scores: 1 for large-cap signals, 0 for small-cap signals, and 0.5 for neutral signals. The average score represents the win rate[40][72] - **Kelly Formula for Allocation**: - Use the Kelly formula to calculate optimal allocation weights for large-cap and small-cap stocks based on odds and win rates - Formula: $ x = \frac{p*b - (1-p)}{b} $ where $ p $ is the win rate, $ b $ is the odds, and $ x $ is the allocation proportion[77] - Adjust weights to ensure they sum to 1 and avoid negative values, forming a complete rotation strategy[77][78] - **Model Evaluation**: The model effectively captures the rotation between large-cap and small-cap stocks, achieving significant excess returns and risk-adjusted performance[78] 2. Model Name: Weighted Size Rotation Strategy - **Model Construction Idea**: Adjust allocation weights between large-cap and small-cap stocks based on the difference in configuration scores derived from odds and win rates[82] - **Model Construction Process**: - Calculate the difference in configuration scores between large-cap and small-cap stocks - Standardize the score difference using a Z-score over the past 250 weeks - Map the standardized score to allocation weights using a predefined mapping table[83] - **Model Evaluation**: This strategy reduces maximum drawdown while maintaining a high level of excess returns and information ratio[84] 3. Model Name: Detailed Style Rotation Model - **Model Construction Idea**: Combine the size rotation model with a growth-value rotation model to form a detailed style rotation strategy, targeting large-cap growth, large-cap value, small-cap growth, and small-cap value[87] - **Model Construction Process**: - Use the size rotation model to determine the size preference (large-cap or small-cap) - Use the growth-value rotation model to determine the style preference (growth or value) - Combine the two signals to allocate to one of the four detailed styles[87] - **Model Evaluation**: The model demonstrates outstanding rotation effects, achieving the highest excess returns and information ratio among all strategies[90][92] --- Model Backtesting Results 1.

Core Viewpoint - The article emphasizes the importance of understanding accounts receivable in the property management industry, particularly in the context of cash flow management and dividend sustainability. It highlights the significant changes in accounts receivable due to recent industry downturns and the need for a balanced development model focusing on scale, quality, and profit [3][4]. Accounts Receivable Analysis - The total accounts receivable for 30 tracked listed property companies increased from 29.18 billion to 75.37 billion from 2020 to 2024, with growth rates of +42.6%, +65.6%, +41.4%, +8.7%, and +1.5% respectively. Notably, from 2023 onwards, the growth rate of accounts receivable is lower than that of operating income, indicating a significant slowdown [3]. - The proportion of accounts receivable from related parties has decreased from 47% to 39% over the past five years, while third-party receivables have increased from 53% to 61%. This trend suggests a gradual reduction in related party risks as the industry stabilizes [4]. - The aging of accounts receivable has worsened, with the proportion of receivables due within one year dropping from 89% in 2019 to 58% in 2024. Consequently, the provision for bad debts has risen sharply from 4% to 26% during the same period, reflecting increased collection difficulties [4]. Investment Recommendations - Companies that demonstrate independent business competitiveness and can effectively reduce related party transactions are deemed favorable. Additionally, firms with strong parent company backgrounds and high rankings in property sales are likely to provide performance support while mitigating related party risks [5]. - Property management companies with natural advantages in merchant payment collection, low long-term arrears, controlled accounts receivable growth, adequate provisions, healthy aging structures, and high collection rates are recommended for investment [5].
