- Model Name: Barra Style Factors; Model Construction Idea: The model tracks the performance of common Barra style factors; Model Construction Process: The model calculates the returns of various style factors such as market capitalization, book-to-market ratio, growth, and earnings expectations; Model Evaluation: The model provides insights into the performance of different style factors over a specific period[4][14] - Factor Name: Ideal Reversal Factor; Factor Construction Idea: The factor identifies the strongest reversal days based on the average transaction amount per trade; Factor Construction Process: 1. Retrieve the past 20 days of data for the selected stock 2. Calculate the average transaction amount per trade for each day 3. Sum the returns of the top 10 days with the highest average transaction amount (M_high) 4. Sum the returns of the bottom 10 days with the lowest average transaction amount (M_low) 5. Calculate the Ideal Reversal Factor as M = M_high - M_low 6. Repeat the above steps for all stocks to calculate their respective Ideal Reversal Factors[5][39][41] - Factor Name: Smart Money Factor; Factor Construction Idea: The factor identifies the participation of institutional investors based on minute-level price and volume data; Factor Construction Process: 1. Retrieve the past 10 days of minute-level data for the selected stock 2. Construct the indicator $St = \frac{|Rt|}{Vt^{0.25}}$, where $Rt$ is the return at minute t and $Vt$ is the volume at minute t 3. Sort the minute-level data by $St$ in descending order and select the top 20% of minutes by cumulative volume as smart money trades 4. Calculate the volume-weighted average price (VWAP) for smart money trades (VWAPsmart) 5. Calculate the VWAP for all trades (VWAPall) 6. Calculate the Smart Money Factor as $Q = \frac{VWAPsmart}{VWAPall}$[5][40][42] - Factor Name: APM Factor; Factor Construction Idea: The factor measures the difference in stock behavior between morning (or overnight) and afternoon sessions; Factor Construction Process: 1. Retrieve the past 20 days of data for the selected stock 2. Calculate the overnight and afternoon returns for the stock and the index 3. Perform a regression of the stock returns on the index returns to obtain residuals 4. Calculate the difference between overnight and afternoon residuals 5. Construct the statistic $stat = \frac{\mu(\delta_t)}{\sigma(\delta_t)/\sqrt{N}}$ 6. Perform a cross-sectional regression of the statistic on the momentum factor to obtain residuals, which are used as the APM Factor[5][41][43][44] - Factor Name: Ideal Amplitude Factor; Factor Construction Idea: The factor measures the difference in amplitude information between high and low price states; Factor Construction Process: 1. Retrieve the past 20 days of data for the selected stock 2. Calculate the daily amplitude (high price/low price - 1) 3. Calculate the average amplitude for the top 25% of days with the highest closing prices (V_high) 4. Calculate the average amplitude for the bottom 25% of days with the lowest closing prices (V_low) 5. Calculate the Ideal Amplitude Factor as V = V_high - V_low[5][46] - Composite Factor: Kaisheng Trading Behavior Composite Factor; Construction Idea: The composite factor combines multiple trading behavior factors using their ICIR values as weights; Construction Process: 1. Perform outlier removal and standardization for each trading behavior factor within the industry 2. Use the past 12 periods' ICIR values as weights to form the composite factor 3. Calculate the composite factor's returns and performance metrics[5][31] Model Backtest Results - Barra Style Factors: Market Capitalization Factor return: 1.73%, Book-to-Market Ratio Factor return: -0.31%, Growth Factor return: 0.13%, Earnings Expectations Factor return: -0.09%[4][14] Factor Backtest Results - Ideal Reversal Factor: IC: -0.050, rankIC: -0.060, IR: 2.46, Long-Short Monthly Win Rate: 77.4%, September Long-Short Return: -0.42%, Last 12 Months Long-Short Monthly Win Rate: 58.3%[6][15] - Smart Money Factor: IC: -0.037, rankIC: -0.061, IR: 2.70, Long-Short Monthly Win Rate: 81.8%, September Long-Short Return: 0.30%, Last 12 Months Long-Short Monthly Win Rate: 83.3%[6][18] - APM Factor: IC: 0.029, rankIC: 0.034, IR: 2.29, Long-Short Monthly Win Rate: 76.4%, September Long-Short Return: 1.68%, Last 12 Months Long-Short Monthly Win Rate: 50.0%[6][22] - Ideal Amplitude Factor: IC: -0.053, rankIC: -0.073, IR: 2.98, Long-Short Monthly Win Rate: 83.2%, September Long-Short Return: 0.40%, Last 12 Months Long-Short Monthly Win Rate: 66.7%[6][26] - Composite Factor: IC: 0.066, rankIC: 0.091, IR: 3.23, Long-Short Monthly Win Rate: 82.1%, September Long-Short Return: 0.57%, Last 12 Months Long-Short Monthly Win Rate: 75.0%[6][31]
