Heston Model — stochastic volatility for realistic options pricing
50k ft — Why care?
Explains why Black-Scholes fails (constant vol assumption) and how the Heston Model introduces stochastic volatility. Captures the volatility smile and skew that basic models miss. Essential for options pricing.
10k ft — Key takeaways
• Black-Scholes assumes constant vol — unrealistic
• Heston models vol as its own random process
• Captures smile and skew for better options pricing

Black-Scholes assumes volatility is constant. The market knows it isn't. 🛑
Enter: The Heston Model. 🧠📈
Instead of treating volatility as a flat number, the Heston Model introduces stochastic volatility. It recognizes that volatility has a mind of its own, constantly shifting and reverting to a mean over time.
By modeling volatility as its own random process, we can actually capture the volatility smile and skew that basic models completely miss. This is how you price options closer to reality.
