Effective options trading strategies based on volatility forecasting recruiting investor sentiment
This study investigates an algorithm for an effective option trading strategy based on superior volatility forecasts using actual option price data for the Taiwan stock market. The forecast evaluation supports the significant incremental explanatory power of investor sentiment in the fitting and forecasting of future volatility in relation to its adversarial multiple factor model, especially the market turnover and volatility index which are referred to as the investors' mood gauge and proxy for overreaction. After taking into consideration the margin based transaction cost, the simulated trading indicates that a long or short straddle 15days before the options' final settlement day based on the 60 day in sample period volatility forecasting recruiting market turnover achieves the best average monthly return of 15.84% This study bridges the gap between option trading, market volatility, and the signal of the investors' overreaction through the simulation of the option trading strategy. The trading algorithm based on the volatility forecasting recruiting investor sentiment could be further applied in electronic trading and other artificial intelligence decision support systems.
