Quantitative Models and Construction Methods - Model Name: CSI All Share Free Cash Flow Index Model Construction Idea: The model aims to select stocks with strong cash flow performance and further refine the selection based on valuation metrics such as free cash flow yield [5][6] Model Construction Process: 1. Define the stock universe by excluding ST/*ST stocks, financial and real estate sectors, and stocks with abnormal price movements or financial irregularities [6] 2. Filter stocks with positive free cash flow and enterprise value, where: $ \text{Free Cash Flow} = \text{Net Cash Flow from Operating Activities} - \text{Cash Paid for Fixed Assets, Intangible Assets, and Other Long-term Assets} $ $ \text{Enterprise Value} = \text{Market Capitalization} + \text{Total Liabilities} - \text{Cash and Cash Equivalents} $ [6][19] 3. Select stocks with positive operating cash flow for the past five years and rank them by profitability quality, defined as: $ \text{Profitability Quality} = \frac{\text{Net Cash Flow from Operating Activities} - \text{Operating Profit}}{\text{Total Assets}} $ Retain the top 80% based on this ranking [6][19] 4. Rank the remaining stocks by free cash flow yield: $ \text{Free Cash Flow Yield} = \frac{\text{Free Cash Flow}}{\text{Enterprise Value}} $ Select the top 100 stocks [6][19] 5. Weight the selected stocks by their free cash flow over the past year, with a cap of 10% on individual stock weights. Adjust the portfolio quarterly [6][19] Model Evaluation: The model effectively captures companies with strong cash flow performance and aligns with the investment theme of free cash flow [6][19] - Model Name: Simulated Free Cash Flow Portfolio Model Construction Idea: This model replicates the CSI Free Cash Flow Index methodology to construct a portfolio for backtesting purposes [19] Model Construction Process: 1. Follow the same stock selection criteria as the CSI Free Cash Flow Index [19] 2. Adjust the portfolio three times a year (April, August, October) [19] Model Evaluation: The simulated portfolio closely mirrors the performance of the CSI Free Cash Flow Index, demonstrating its robustness [23] Model Backtesting Results - CSI Free Cash Flow Index: - Annualized Return: 18.75% - Annualized Volatility: 22.79% - Sharpe Ratio: 0.82 [15][16] - Simulated Free Cash Flow Portfolio: - Annualized Return: 18.75% - Annualized Volatility: 23.40% - Sharpe Ratio: 0.80 [21][23] Quantitative Factors and Construction Methods - Factor Name: Revenue-to-Free Cash Flow Ratio Factor Construction Idea: This factor measures the proportion of revenue that translates into free cash flow, highlighting companies with strong revenue generation but weak cash flow performance [40] Factor Construction Process: $ \text{Revenue-to-Free Cash Flow Ratio} = \frac{\text{Revenue} - \text{Free Cash Flow}}{\text{Revenue}} $ [40] Factor Evaluation: The factor shows low correlation with common factors, indicating its uniqueness [44] - Factor Name: Quadrant Analysis Factor Factor Construction Idea: Classifies stocks into four quadrants based on the marginal changes in revenue and free cash flow [51] Factor Construction Process: 1. Divide stocks into four groups: - Revenue growth and free cash flow growth - Revenue growth and free cash flow decline - Revenue decline and free cash flow growth - Revenue decline and free cash flow decline [51] 2. Construct equal-weighted portfolios for each quadrant [54] Factor Evaluation: The "double growth" quadrant (revenue and free cash flow growth) delivers the highest annualized return, while the "double decline" quadrant performs the worst [58] Factor Backtesting Results - Revenue-to-Free Cash Flow Ratio: - RankIC Mean: -2.28% (CSI All Share), -4.17% (CSI 300), -3.09% (CSI 500), -1.63% (CSI 1000) - RankIC IR: -0.51 (CSI All Share), -0.43 (CSI 300), -0.46 (CSI 500), -0.25 (CSI 1000) [46] - Quadrant Analysis Factor: - "Double Growth" Portfolio: Annualized Return: 13.20% - "Double Decline" Portfolio: Annualized Return: 7.89% [58]
