Quantitative Models and Construction Methods 1. Model Name: Heston Model - **Model Construction Idea**: The Heston model is used to calculate the implied volatility of near-month at-the-money options, serving as a market fear index. Implied volatility reflects market participants' expectations of future volatility [8] - **Model Construction Process**: The Heston model is a stochastic volatility model where the variance of the asset price follows a mean-reverting square-root process. The model is defined by the following equations: $ dS_t = \mu S_t dt + \sqrt{v_t} S_t dW_t^1 $ $ dv_t = \kappa (\theta - v_t) dt + \sigma \sqrt{v_t} dW_t^2 $ Here: - \( S_t \): Asset price - \( v_t \): Variance process - \( \mu \): Drift rate of the asset price - \( \kappa \): Rate of mean reversion of variance - \( \theta \): Long-term variance - \( \sigma \): Volatility of variance - \( W_t^1, W_t^2 \): Two Wiener processes with correlation \( \rho \) [8] - **Model Evaluation**: The Heston model is widely recognized for its ability to capture the stochastic nature of volatility, making it suitable for modeling market fear indices [8] --- Quantitative Factors and Construction Methods 1. Factor Name: Multi-Long-Short Ratio Scissor Difference - **Factor Construction Idea**: This factor is based on the difference between the number of long and short signals within industry index constituent stocks. It is used to construct industry timing strategies [15] - **Factor Construction Process**: - Define the number of long and short signals for each industry index constituent stock on a given day - If no long signals are present, set the long signal count to 0; similarly, if no short signals are present, set the short signal count to 0 - Calculate the scissor difference as the difference between the long and short signal counts - Normalize the scissor difference to obtain the scissor difference ratio [15] - **Factor Evaluation**: The backtesting results show that the timing model based on this factor outperforms the respective industry indices in all cases, demonstrating excellent historical performance [15] --- Backtesting Results of Models 1. Heston Model - **Implied Volatility Results**: - SSE 50: 13.63% (down 2.78% WoW) - SSE 500: 15.75% (down 3.31% WoW) - CSI 1000: 17.15% (down 3.26% WoW) - CSI 300: 13.96% (down 2.31% WoW) [10] --- Backtesting Results of Factors 1. Multi-Long-Short Ratio Scissor Difference - **Performance Metrics**: - Timing models based on this factor outperformed their respective industry indices in all cases, achieving a 100% success rate in backtesting [15]
