- The "Day and Night Convergence" new momentum factor is constructed based on the price-volume relationship during intraday and overnight trading periods, aiming to improve the stability of traditional momentum factors by incorporating transaction volume information[7][6][1] - The construction process involves splitting trading periods into day and night sessions, analyzing their respective price-volume relationships, and synthesizing a new momentum factor. The factor's IC mean is -0.045, annualized ICIR is -2.59, and its 10-group long-short strategy achieved an annualized return of 22.64%, IR of 2.85, monthly win rate of 83.33%, and maximum drawdown of 5.79% during the backtest period from 2014/01/01 to 2022/07/31[7][6][1] - The factor demonstrates superior stock selection ability compared to traditional momentum factors, which had an IR of 1.09, monthly win rate of 62.75%, and maximum drawdown of 20.35% during the same backtest period[6][7] - In the full A-share market (excluding Beijing Stock Exchange stocks), the "Day and Night Convergence" factor's 10-group long-short strategy achieved an annualized return of 17.93%, annualized volatility of 8.73%, IR of 2.05, monthly win rate of 76.98%, and maximum drawdown of 9.07% from February 2014 to August 2025[14][7][1] - For August 2025, the factor's 10-group long portfolio returned 9.49%, the short portfolio returned 9.58%, and the long-short strategy returned -0.10%[10][1]

Quantitative Models and Construction Methods 1. Model Name: "Day and Night Convergence" New Momentum Factor - **Model Construction Idea**: The model improves traditional momentum factors by incorporating the price-volume relationship during intraday and overnight trading sessions, leveraging the distinct characteristics of these two periods to enhance signal strength and stability [7][6] - **Model Construction Process**: 1. The trading period is divided into intraday and overnight sessions [7] 2. Price-volume relationships are separately analyzed for each session to identify unique patterns and characteristics [7] 3. The insights from these analyses are combined to construct a new momentum factor, referred to as the "Day and Night Convergence" factor [7] - **Model Evaluation**: The model demonstrates significant improvement in stability and performance compared to traditional momentum factors, effectively addressing the instability issues observed in the A-share market [6][7] --- Model Backtesting Results 1. "Day and Night Convergence" New Momentum Factor - **Annualized Return**: 18.08% [14] - **Annualized Volatility**: 8.75% [14] - **Information Ratio (IR)**: 2.07 [14] - **Monthly Win Rate**: 77.54% [14] - **Maximum Drawdown**: 9.07% [14]
