Quantitative Factors and Construction Methods 1. Factor Name: Market Style Factors - Construction Idea: The market style factors track the balance and volatility between different market styles, such as large-cap vs. small-cap and value vs. growth[11][13] - Construction Process: - Style Balance: Measure the relative performance of large-cap vs. small-cap stocks and value vs. growth stocks to determine the market's style preference[11] - Style Volatility: Calculate the fluctuations in the relative performance of these styles over time to assess the stability of the market's style preference[11] - Evaluation: The market style factors showed a balanced preference between large-cap and small-cap stocks, as well as between value and growth stocks. Additionally, the volatility of these styles continued to decline, indicating a more stable market environment[11][13] 2. Factor Name: Market Structure Factors - Construction Idea: These factors analyze the dispersion of returns, sector rotation, and trading concentration to understand the structural dynamics of the market[11][13] - Construction Process: - Return Dispersion: Measure the excess return dispersion across industry indices to evaluate the variability in sector performance[11] - Sector Rotation: Assess the speed of sector rotation by tracking changes in sector leadership over time[11] - Trading Concentration: Calculate the proportion of trading volume concentrated in the top 100 stocks and the top 5 industries to gauge market concentration[11] - Evaluation: The market structure factors indicated a decline in return dispersion, slower sector rotation, and reduced trading concentration, suggesting a more evenly distributed market environment[11][13] 3. Factor Name: Market Activity Factors - Construction Idea: These factors measure the overall activity and liquidity of the market through volatility and turnover rates[12][13] - Construction Process: - Volatility: Calculate the index-level volatility to assess market stability[12] - Turnover Rate: Measure the turnover rate of the market to evaluate trading activity[12] - Evaluation: The market activity factors showed a decline in both volatility and turnover rates, reflecting reduced market activity, likely influenced by the holiday period[12][13] 4. Factor Name: Commodity Market Factors - Construction Idea: These factors analyze the performance, momentum, and liquidity of various commodity sectors[27][30] - Construction Process: - Trend Strength: Measure the strength of price trends in different commodity sectors, such as energy, metals, and agriculture[27] - Basis Momentum: Calculate the basis momentum, particularly for the metals sector, to assess the relative strength of futures prices compared to spot prices[27][30] - Volatility: Track the volatility levels across commodity sectors to evaluate risk[27][30] - Liquidity: Measure the liquidity of commodity sectors to assess trading ease[27][30] - Evaluation: The commodity market factors showed mixed performance, with strong trends in energy and metals, weaker trends in agriculture, and high volatility across sectors. Liquidity remained stable overall[27][30] 5. Factor Name: Options Market Factors - Construction Idea: These factors analyze the implied volatility and skewness of options to infer market sentiment and expectations[35] - Construction Process: - Implied Volatility: Measure the implied volatility levels of options on major indices, such as the SSE 50 and CSI 1000, to gauge market uncertainty[35] - Skewness: Analyze the skewness of call and put options to understand market expectations for upward or downward movements[35] - Evaluation: The options market factors indicated a divergence in sentiment, with increased optimism for small-cap stocks (CSI 1000) and reduced optimism for large-cap stocks (SSE 50). This suggests a potential shift in market preference post-holiday[35] 6. Factor Name: Convertible Bond Market Factors - Construction Idea: These factors evaluate the valuation and trading activity of the convertible bond market[38] - Construction Process: - Valuation: Measure the average conversion premium of convertible bonds to assess their relative attractiveness[38] - Trading Activity: Track the trading volume and turnover in the convertible bond market to evaluate market interest[38] - Evaluation: The convertible bond market factors showed a slight increase in valuation, with trading activity continuing to recover, indicating improving market sentiment[38] --- Factor Backtesting Results 1. Market Style Factors - Style Balance: Balanced between large-cap and small-cap, as well as value and growth[11][13] - Style Volatility: Continued decline in volatility, indicating stability[11][13] 2. Market Structure Factors - Return Dispersion: Declined, indicating less variability in sector performance[11][13] - Sector Rotation: Slowed down, suggesting reduced changes in sector leadership[11][13] - Trading Concentration: Decreased, reflecting a more evenly distributed market[11][13] 3. Market Activity Factors - Volatility: Declined, indicating reduced market risk[12][13] - Turnover Rate: Decreased, reflecting lower trading activity[12][13] 4. Commodity Market Factors - Trend Strength: Strong in energy and metals, weak in agriculture[27][30] - Basis Momentum: Highest in metals, declined in other sectors[27][30] - Volatility: High across all sectors[27][30] - Liquidity: Stable overall[27][30] 5. Options Market Factors - Implied Volatility: Increased for both SSE 50 and CSI 1000, indicating higher uncertainty[35] - Skewness: Positive for CSI 1000 (small-cap optimism), negative for SSE 50 (large-cap caution)[35] 6. Convertible Bond Market Factors - Valuation: Slight increase in average conversion premium[38] - Trading Activity: Continued recovery in trading volume[38]
