Quantitative Models and Construction - Model Name: Three-dimensional Timing Framework Construction Idea: The model integrates liquidity, divergence, and prosperity indicators to assess market timing and risk levels[7][14][16] Construction Process: 1. Liquidity Index: Tracks market liquidity trends[22] 2. Divergence Index: Measures market disagreement levels[20] 3. Prosperity Index: Evaluates industrial prosperity trends[26] 4. Combines these three dimensions to form a comprehensive timing framework[14] Evaluation: Demonstrates stable performance in identifying market timing opportunities[16] - Model Name: Financing-Active Large Order Flow Intersection Strategy Construction Idea: Combines financing and large order flows to identify industries with strong capital inflows[34][40] Construction Process: 1. Financing Flow Factor: Neutralizes market capitalization and calculates the net financing buy-sell difference over a 50-day average[40] 2. Active Large Order Flow Factor: Neutralizes transaction volume and ranks net inflows over the past year, using a 10-day average[40] 3. Filters extreme industries and integrates both factors to enhance stability[40] Evaluation: Achieves stable annualized excess returns with reduced drawdowns compared to other strategies[40] Quantitative Models Backtesting Results - Three-dimensional Timing Framework: Historical performance shows stable risk assessment and timing capabilities[16] - Financing-Active Large Order Flow Intersection Strategy: - Annualized excess return: 13.5% - IR: 1.7[40] - Weekly absolute return: -1.6% - Weekly excess return: -0.1%[40] Quantitative Factors and Construction - Factor Name: Valuation Factors Construction Idea: Focuses on valuation metrics such as earnings yield and book-to-market ratios[46][47] Construction Process: 1. Earnings Yield (ep_fy3): $ ep_fy3 = \frac{1}{PE_FY3} $ 2. Book-to-Market Ratio (bp): $ bp = \frac{Shareholder_Equity}{Market_Value} $ 3. Neutralizes industry and market capitalization effects[46][48] Evaluation: Demonstrates strong performance across multiple timeframes and indices[46][48] - Factor Name: Growth Factors Construction Idea: Captures growth metrics such as revenue and profit growth rates[46][49] Construction Process: 1. Revenue Growth (yoy_or): $ yoy_or = \frac{Current_Revenue - Previous_Revenue}{Previous_Revenue} $ 2. Profit Growth (yoy_np): $ yoy_np = \frac{Current_Net_Profit - Previous_Net_Profit}{Previous_Net_Profit} $ 3. Neutralizes industry and market capitalization effects[46][50] Evaluation: Performs better in large-cap indices and shows consistent excess returns[49][50] Quantitative Factors Backtesting Results - Valuation Factors: - Weekly excess return: 1.5%-2.18% - Monthly excess return: 1.46%-3.85%[48] - Growth Factors: - Weekly excess return: 1.52%-3.89% - Monthly excess return: 0.79%-3.02%[50] Quantitative Portfolios and Construction - Portfolio Name: Index Enhancement Portfolios Construction Idea: Adjusts factor selection based on research coverage to enhance index performance[51] Construction Process: 1. Divides stocks into high and low research coverage domains[51] 2. Applies suitable factors for each domain to optimize portfolio construction[51] Evaluation: Outperforms original index selection methods in terms of excess returns[51] Quantitative Portfolios Backtesting Results - Index Enhancement Portfolios: - HS300: - Weekly absolute return: -0.89% - Weekly excess return: 0.03% - Annualized excess return: 7.77%[52] - CSI500: - Weekly absolute return: 0.16% - Weekly excess return: 0.40% - Annualized excess return: 9.82%[52] - CSI1000: - Weekly absolute return: -0.58% - Weekly excess return: -0.74% - Annualized excess return: 9.26%[52]
