Quantitative Models and Construction Methods 1. Model Name: Three-Dimensional Timing Framework - Model Construction Idea: The model integrates three dimensions—liquidity, divergence, and prosperity—to assess market trends and provide timing signals[10][15] - Model Construction Process: - Liquidity Index: Measures the market's liquidity trend - Divergence Index: Tracks the degree of market disagreement - Prosperity Index: Reflects the overall market sentiment and economic conditions - The framework combines these three indices to determine market phases, such as "sustained decline" or "rebound"[10][15] - Model Evaluation: The model is effective in identifying market trends and has been used to guide portfolio positioning, such as recommending a half-position strategy during weak market phases[10][15] 2. Model Name: Capital Flow Resonance Strategy - Model Construction Idea: This strategy identifies industries with strong capital inflows by combining two types of capital flow factors—margin trading and large orders—to generate alpha[27][31] - Model Construction Process: - Margin Trading Factor: Defined as the market-neutralized net margin buy minus net margin sell, averaged over the last 10 days and calculated as a week-over-week change rate - Large Order Factor: Defined as the net inflow ranking of large orders, neutralized by the time series of trading volume over the past year, and averaged over the last 10 days - The strategy excludes extreme industries and combines the two factors to identify industries with capital flow resonance[31][33] - Historical Performance: Since 2018, the strategy achieved an annualized excess return of 14.5% with an IR of 1.4[31] - Model Evaluation: The strategy demonstrates stable performance and lower drawdowns compared to other capital flow strategies[31] 3. Model Name: Research Coverage-Based Index Enhancement - Model Construction Idea: This model enhances index performance by selecting factors based on research coverage levels within different domains of the index[45] - Model Construction Process: - The model divides the index into high and low research coverage domains - Different factors are applied to each domain to optimize stock selection - The approach is applied to indices such as CSI 300, CSI 500, and CSI 1000[45] - Model Evaluation: The model outperforms traditional factor selection methods by tailoring factors to specific research coverage levels[45] --- Model Backtesting Results 1. Three-Dimensional Timing Framework - No specific numerical backtesting results provided in the report 2. Capital Flow Resonance Strategy - Absolute Return: -7.4% last week - Excess Return: -0.7% last week - Historical Annualized Excess Return: 14.5% - IR: 1.4[31] 3. Research Coverage-Based Index Enhancement - CSI 300: Weekly excess return of 0.16%, annualized excess return of 11.22%, Sharpe ratio of 1.99 - CSI 500: Weekly excess return of 0.49%, annualized excess return of 13.35%, Sharpe ratio of 2.79 - CSI 1000: Weekly excess return of 1.16%, annualized excess return of 11.93%, Sharpe ratio of 2.02[45] --- Quantitative Factors and Construction Methods 1. Factor Name: Volatility Factors (e.g., return_std_3m, return_std_6m) - Factor Construction Idea: Measures the standard deviation of returns over different time horizons to capture market volatility[37][38] - Factor Construction Process: - return_std_3m: Standard deviation of returns over the past 3 months - return_std_6m: Standard deviation of returns over the past 6 months - These factors are neutralized for market capitalization and industry effects[37][38] - Factor Evaluation: These factors performed well across different timeframes and indices, with weekly excess returns exceeding 2%[38][39] 2. Factor Name: Profitability Factors (e.g., ep_fy1, ebit_to_ev) - Factor Construction Idea: Measures profitability using metrics like earnings yield and EBIT-to-enterprise value ratio[37][38] - Factor Construction Process: - ep_fy1: Inverse of forward price-to-earnings ratio - ebit_to_ev: EBIT divided by enterprise value, where EV = financial liabilities - financial assets + market capitalization - Factors are neutralized for market capitalization and industry effects[37][38] - Factor Evaluation: These factors showed strong performance, particularly in small-cap indices, with weekly excess returns exceeding 2%[38][39] 3. Factor Name: Behavioral Factors (e.g., rate_up_rate_90d) - Factor Construction Idea: Captures market sentiment by tracking changes in analyst ratings over a 90-day period[39][40] - Factor Construction Process: - rate_up_rate_90d: Proportion of rating upgrades over the past 90 days - Neutralized for market capitalization and industry effects[39][40] - Factor Evaluation: This factor performed well across all indices, with excess returns ranging from 2.86% to 5.94% depending on the index[39][40] --- Factor Backtesting Results 1. Volatility Factors - return_std_3m: Weekly excess return of 2.47%, monthly excess return of 2.26%, annual excess return of 5.37% - return_std_6m: Weekly excess return of 2.37%, monthly excess return of 1.76%, annual excess return of 1.12%[38][39] 2. Profitability Factors - ep_fy1: Weekly excess return of 2.26%, monthly excess return of 2.76%, annual excess return of -0.48% - ebit_to_ev: Weekly excess return of 2.00%, monthly excess return of 1.17%, annual excess return of 3.61%[38][39] 3. Behavioral Factors - rate_up_rate_90d: Weekly excess return of 2.86% in CSI 300, 4.60% in CSI 500, 5.94% in CSI 1000, and 3.14% in CSI 2000[39][40]
