Quantitative Models and Construction Methods 1. Model Name: PB-ROE-50 - Model Construction Idea: The model is based on the PB (Price-to-Book) and ROE (Return on Equity) metrics, aiming to select stocks with favorable valuation and profitability characteristics[23] - Model Construction Process: - Stocks are selected based on their PB and ROE metrics - The portfolio is constructed by ranking stocks within the universe (e.g., CSI 800, CSI 500, or the entire market) - Regular rebalancing is performed to maintain the portfolio's alignment with the PB-ROE strategy[23][24] - Model Evaluation: The model demonstrates consistent positive excess returns in certain stock pools, indicating its effectiveness in capturing valuation and profitability factors[23] 2. Model Name: Large Block Trade Portfolio - Model Construction Idea: This model leverages the information embedded in large block trades, focusing on stocks with high transaction amounts and low volatility[29] - Model Construction Process: - Stocks are filtered based on "large transaction amount" and "low 6-day transaction volatility" - Monthly rebalancing is applied to maintain the portfolio's characteristics - The strategy is designed to capture the excess information from large block trades[29][30] - Model Evaluation: The model effectively identifies stocks with strong subsequent performance, as evidenced by its positive excess returns[29] 3. Model Name: Directed Issuance Portfolio - Model Construction Idea: This model captures the event-driven effects of directed issuance (private placements), focusing on stocks involved in such events[34] - Model Construction Process: - Stocks are selected based on the announcement date of directed issuance events - Factors such as market capitalization, rebalancing cycle, and position control are considered in portfolio construction - The strategy is designed to exploit the market inefficiencies surrounding directed issuance events[34][35] - Model Evaluation: The model demonstrates the ability to generate positive excess returns, indicating the continued relevance of directed issuance events in investment strategies[34] --- Model Backtesting Results 1. PB-ROE-50 Model - Excess Return (CSI 500): -0.12% (weekly), 2.07% (YTD)[24] - Excess Return (CSI 800): 0.63% (weekly), 2.60% (YTD)[24] - Excess Return (Entire Market): 0.65% (weekly), 3.10% (YTD)[24] 2. Large Block Trade Portfolio - Excess Return: 0.01% (weekly), 23.39% (YTD)[30] 3. Directed Issuance Portfolio - Excess Return: 0.19% (weekly), 4.26% (YTD)[35] --- Quantitative Factors and Construction Methods 1. Factor Name: Logarithmic Market Cap Factor - Factor Construction Idea: This factor captures the size effect by using the logarithm of market capitalization[12][13] - Factor Construction Process: - The logarithm of the market capitalization of each stock is calculated - Stocks are ranked based on their logarithmic market cap values - The factor is applied to identify small-cap or large-cap stocks depending on the direction of the strategy[12][13] - Factor Evaluation: The factor shows strong performance in multiple stock pools, particularly in small-cap-dominated markets[12][14][16] 2. Factor Name: Momentum-Adjusted Large Trades - Factor Construction Idea: This factor measures the impact of large trades adjusted for momentum effects[12][13] - Factor Construction Process: - Large trade volumes are adjusted for recent momentum trends - Stocks are ranked based on the adjusted trade volumes - The factor is used to identify stocks with significant large trade activity and positive momentum[12][13] - Factor Evaluation: The factor demonstrates positive returns in certain stock pools, indicating its ability to capture momentum-driven large trade effects[12][14] 3. Factor Name: 6-Day Moving Average of Transaction Amount - Factor Construction Idea: This factor smooths transaction amounts over a 6-day period to identify trends in trading activity[12][13] - Factor Construction Process: - A 6-day moving average of transaction amounts is calculated for each stock - Stocks are ranked based on their moving average values - The factor is applied to identify stocks with increasing or decreasing trading activity[12][13] - Factor Evaluation: The factor shows mixed performance, with positive returns in some stock pools and negative returns in others[12][14] --- Factor Backtesting Results 1. Logarithmic Market Cap Factor - Excess Return (CSI 300): 1.63% (weekly)[12][13] - Excess Return (CSI 500): 1.08% (weekly)[14][15] - Excess Return (Liquidity 1500): 0.65% (weekly)[16][17] 2. Momentum-Adjusted Large Trades - Excess Return (CSI 300): 1.37% (weekly)[12][13] - Excess Return (CSI 500): 1.05% (weekly)[14][15] - Excess Return (Liquidity 1500): -1.23% (weekly)[16][17] 3. 6-Day Moving Average of Transaction Amount - Excess Return (CSI 300): 1.34% (weekly)[12][13] - Excess Return (CSI 500): 0.63% (weekly)[14][15] - Excess Return (Liquidity 1500): -0.32% (weekly)[16][17]
