What is the Model of Heston Model?

The Heston model is a stochastic volatility model used for pricing options, distinguishing itself from the Black-Scholes model by allowing volatility itself to be a random variable. This framework captures the empirical observation that volatility often exhibits mean reversion and correlation with the underlying asset price. The model provides a more realistic representation of market dynamics, particularly in markets with significant volatility clustering.

What is the Volatility of Heston Model?

In the Heston model, volatility follows its own stochastic process, meaning it fluctuates randomly over time rather than remaining constant. This approach allows for the modeling of volatility smiles and skews, which are common features in options markets where implied volatility varies across different strike prices. The model's parameters describe the long-term mean, rate of mean reversion, and volatility of volatility.

What is the Process of Heston Model?

The Heston model's process involves two correlated stochastic differential equations: one for the underlying asset price and one for its variance. This dual-process structure enables more accurate pricing of options, especially those with longer maturities or those sensitive to volatility changes. The model's ability to account for correlation between asset price and volatility is crucial for capturing the leverage effect observed in many financial markets.
