Option Pricing Interpretation
The statistics reveal that while the Black-Scholes model provides a useful theoretical baseline, the real-world mosh pit of market volatility demands a far more sophisticated arsenal—from stochastic models that chase crashing puts to rough volatility that clings to persistence, neural networks that outpace Monte Carlo, and local volatility that sometimes guesses the path—all in a relentless, witty quantification of our attempts to tame the financial chaos.
