This chapter explores the use of the Heston stochastic volatility model in improving traditional stock trading approaches. It highlights the model's ability to capture market uncertainty, leading to more accurate predictions of optimal trading strategies. The discussion covers the model's mathematical formulation and simplification techniques.
Heston stochastic volatility model improves upon traditional models by capturing inherent uncertainty in volatility.
The model uses asymptotic expansion and linear approximation to solve the complex Hamilton-Jacobi-Bellman equation.
Incorporating market impact modifies stock price dynamics, adding a term depending on buy/sell order difference.
